I like OLED a lot more than LCD. The superior color gamut, deep blacks, and motion clarity in particular are all great.
However, OLED always seems to cause me more eye fatigue than LCD.
I've tried eliminating PWM flickering with transparent overlays or DC dimming. It helps, but not to a point of being as easy on the eyes as LCD, let alone how much it ruins color reproduction at low brightness. I've tried blue light filters, both glasses and software. Nope.
After switching to a CRT at my desk last summer, I've gotten a lot pickier. Gaming IPS LCDs have good colors, but the ones that are acceptably fast have terrible blacks and vice versa.
Still, my experience with OLED has mostly been with phones, tablets, and showrooms. Maybe I just need to try a LG CX for awhile.
Anyone else have issues with OLED?

I don’t really notice any flickering on either my tv or monitor. If you can handle a crt, you should be easily able to handle an OLED.
 
No flickering on mine, the only thing around eye strain is when doing HDR at night, it is a little too bright for me, I have to dim it

I found the same when I was using my c7 as a monitor but I assumed the fatigue was due to the ridiculous size and how close I was sitting.
 
Many old ones did. But ya, it's nice most of the good ones these days don't.
Which one did?
The oldest LG OLED television test from Rtings (september 10 2015) shows no PWM modulation.

In fact, as there is no backlight in any OLED display, there is no way or need to use PW modulated backlight.

Mobile OLED displays definitely do have PWM. My Samsung S8 flickers at 240Hz at anything below max brightness. I think it's due to power restraints making distortionless DC dimming like OLED TVs have impossible. Not sure, though.
I didn't dig deep into Rtings before, that's good to know. What I read saying TVs did have PWM must have been misinformed, which is believable.

I know right? I don't get it either. CRTs above 75Hz are absolutely fine for me. But my phone's 240Hz PWM makes me feel like I'm staring into a sunlit magnifying glass; using software to eliminate it with psuedo DC dimming for sure helps. Maybe OLED's pattern of flicker is somehow harsher than a CRT's? I don't know.
Why eliminating PWM flicker only mostly solves the issue is what's odd to me. Non-flickering OLED should be just as comfortable as LCD or CRT, but it's not.
Like I said, maybe I just need to give a big screen a try for a bit.

It most probably was due to ridiculous side and how close you were sitting.

Eye fatigue depends on many factors and different LCD panels will tire eyes differently.

From monitors I use the best eye-friendly monitor has RGB-LED backlight and PWM flickering. It flickers always, even at 100% and still I can look at it all the time and in fact I do. The monitor, HP LP2480zx is bliss to look at. For that reason I have three 🤩 Second best has HD600 and is PWM-free but I would expect monitor for high brightness to be good for eyes. 250cd/m2 on it is default brightness. Worst monitor were W-LED and all PWM-free. Most W-LED monitors are just bad when it comes to eye comfort and cannot be used at anything more than 100-120cd/m2. It was better with CCFL monitors, even if they flickered a little below 100% brightness - but with CCFL flickering was more gentle at least. Still some CCFL lamps were pretty terrible. Just like with W-LED, some are ok while others are just screaming... or are my eyes screaming? Something definitely is when using bad panels.

If OLED are bad I would not say but I do not have much OLEDs.
Had them in phones but I think they were pretty ok. My current phone and my last phone both had high PPI (>500) IPS panels and not OLED and are pretty good. The issue I had with OLED was low PPI + Pentile subpixel arrangement. I can see and read Hardforum fonts at >500 PPI without scaling (it is possbile to not have scaling on phone in web browser) on something like 2560x1600 5.5" so the OLED subpixels are pretty irritating to me. Would much more prefer RGB subpixels. Other than bad subpixels and maybe somewhat dirty look to uniform surfaces I would not say there is anything wrong with OLED tech.

Also different OLED panels use different tech. So something like LG TV's will use completely different OLED technology than Samsung AMOLED. In fact these OLED TV panels from LG use blue OLED's + yellow phosphor to give white light and then use color filters so the light spectrum itself should be pretty similar to LCD. I am personally waiting until they make better OLED TV's like QD-OLED that uses quantum dots instead color filters and doesn't use yellow phosphors at all. Those should be considerably nicer overall and brighter (read: will burn-in slower ;) )
 
I haven't encountered any kind of eye fatigue using either of my OLEDs. My 65" C9 is about 8' and my 55" CX I use as a monitor it sit about 3' from.

It could be the viewing distance / size. It may be an uncomfortable foxed focal point for your eyes for long term viewing leading to eye fatigue. Another possibility is the contrast / brightness but you seem to have explored that side of it so I would consider the focal length / viewing distance. Do you wear glasses or have you been to an optometrist? I didn’t think I needed glasses until recently since I could see fine but noticed eye fatigue after longer computer sessions, and it turned out I needed glasses for computer use and reading only.
 
"The superior color gamut"

Actually color volume is one of OLEDs weak points. I found that out comparing my 48CX directly next to my PG32UQX which has way better colors.

The OLED is probably just better calibrated.

There is really no comparison in HDR when it comes to bright colors. OLED's are really muted compared to a PG32UQX. It's really one of the Asus' strongest characteristics because nothing outside of those $10000+ professional displays comes close to it's gamut coverage.

Here is the G9 Neo with it's really poor 89% DCI-P3 color gamut vs the C1 in terms of color volume:

In that case I agree. 7% and 9% difference in color gamut is noticeable indeed.
In sRGB space, though, I expect them to look identical.
 
Only fatigue I got was from the color shift on some solid lighter colors like white and grey giving me an annoying cyan color off-axis. More mental fatigue than eye fatigue.
 
No fatigue here, btw. OLED is very good for eyesight because you have to move your eye balls around the screen, since it is large, unlike staring into a smaller PC monitor, and that staring deteriorates the eyesight. Also OLED does not use PWM.
 
If you are sensitive to flicker----you may also be sensitive to the near instantaneous pixel response of OLED. And therefore.....60hz refresh may feel stuttery, to you. I've seen a fair amount of people say that 60hz content such as games, on OLED, can kind of feel like 30hz on an LCD. Due to that drastically lower pixel response.
 
I don't find 60hz to be stuttery but 30FPS and below is far more choppy looking than on a LCD.

Film content which is I think 24hz looks so bad at times that I feel like I can count the frames.
 
Yeah 30 fps console games on OLED is not a great experience. You get used to it but the judder can be noticeable. No problems at 60 fps.
 
My LG OLED TV is easier on my eyes than any LCD I've had (the measured brightness is set to around the same value on those displays, I have a meter). It also doesn't affect my sleepiness like LCDs do, LCDs seem to keep me awake far longer than I should be, and it's a pain the next day (if I have to get up). I guess that's likely related to the blue light thing, since OLEDs should have almost none. (I never took any measures against that, besides using a reasonable brightness and decently calibrated displays). Or maybe it's just because of black not being black, so more light shooting at my eyes overall.

But yeah low framerate doesn't look good on OLED that is something to keep in mind. And no real experience with OLED phones and tablets here, somehow never owned one so never used one for more than a few minutes. But reading reviews there seems to be some that do have PWM, for power saving reasons (I would imagine).

How so?
LG OLED's (if you are refering to those) are using white oleds + color filters for each RGB subpixel. While OLED is blue OLED + yellow phosphor which is the same trick they use in W-LED from which most LCD backlight is made these days. LCD also use color filters.

True OLED like AMOLED uses different organic LEDs for each color.
QD-OLED, the tech I am personally waiting for will use blue OLED + quantum dot filters. Hopefully without white subpixels. They are there to help with brightness making high brightness gamut smaller than low brightness gamut making HDR highlights less vibrant. Overall current OLED TV subpixel layout is very not optimal for viewing with large gaps between pixels. I really hope for normal RGB layout and if not then at least something resembling one.
 
I'm not sure but a quick Google returns a lot of results including a certification that LG OLED TVs have which says they emit much less blue light than comparable LCD TVs.
 
I did experience eye fatigue with the out of the box settings of my C1 since I had to break it in for about 100 hours before bothering to calibrate it. I lowered the brightness for more comfortable viewing. After calibration with an SDR luminance target of 110cd/m2 which is the optimum for my room lighting conditions, no more eye fatigue.

Yeah...
LG CX spectrum at 6500K
spectral_6500k.png


If I showed the "CX OLED" graph to random person and ask what produces this spectral distribution they would say it is typical W-LED backlight of the typical W-LED monitor and not "OLED"

LG 27GN950 at 6500K
spectral_6500k.jpg

If I showed this they would probably start going OLED direction. It doesn't look like typical CCFL or even CRT and certainly doesn't look like typical W-LED.
I have LG 27GP950 which uses probably the same or very similar panel and in fact it is very comfortable to use. Previous W-LED panel was horrible in comparison.

In comparison actual OLED monitor (LG 32EP950) with true RGB OLEDs. Each pixel is its own type of organic filter. No blue OLED + yellow phosphor + color filters nonsense.

Light spectrum matters a lot for eye comfort. It might be even the single most important factor.
I have seen bad displays with light that causes my eyes to experience pain, especially at higher brightness levels and I have seen displays which can be watched very bright without any issues. People jumped to conclusion that PWM causes these issues but that does not explain why some PWM monitors are perfectly usable while some PWM-free monitors are terrible. In fact most early W-LED panels had terrible LEDs in them with high luminance blue light peaks. If on top of that they had flicker then it is easy explanation. Easier than "light spectrum" and some graphs... though from this graphs one can easily see there is something going on there ;)

In any way, LG OLED TV's are not really good representation for OLED when it comes to light spectrum.
Somewhere in the future LG plans to replace their white OLEDs + color filters with blue OLEDs + Quantum Dot filters. This will change light spectrum a lot. Hopefully they will make them comfortable to use rather than reach for other parameters at expense of comfort. I mean it is possible to sacrifice eye comfort, though I do not think it would be a very good idea, especially for TV :)
 
No issues at all. I've had by LG B6 for 5 years now and recently picked up a sony a80j.
 
XoR_, you're doing the Lord's work. Are you measuring those spectrums yourself?

I strongly prefer CRTs. I think displays have gotten so complex that our reactions to them aren't understood.

I experience eye fatigue, yeah; I think more importantly, new displays cause anxiety, foggy thinking, and they keep you up at night. CRTs don't. I don't fully understand it, but I'm almost sure it's due to spectrum. It might be to some degree PWM backlights, but they're less common now. It's also not due to sharpness. If sharpness kept you up at night, CRTs would kill you, and 4k displays would be a panacea. That certainly isn't the case though.

I think a good example of how complex displays have gotten is the perception of brightness. I think the perception of brightness is how we ended up on these blue LED things in the first place. People preferred them at the store, when technologies were changing. But man, on your desk, they're awful.
 
No fatigue here, btw. OLED is very good for eyesight because you have to move your eye balls around the screen, since it is large, unlike staring into a smaller PC monitor, and that staring deteriorates the eyesight. Also OLED does not use PWM.
This is utterly false. Your eyes are always moving when reading, eyestrain is worse with a large OLED because of how much extra movement they require (not just eye, but head and neck) which flies in the face of every article ever published about ergonomic comfort and eye fatigue. You will not find people sitting 14" away from a giant television in any office in the world, the only place you'll find that is on this forum.
 
XoR_, you're doing the Lord's work. Are you measuring those spectrums yourself?
Not yet.
I plan on getting i1 Pro 2 spectrometer or something similar. I will need it for hardware calibration of LG 27GP950 and spectrometer is really the only calibration tech that can universally work with any display tech.

BTW. It is possible to see this spectrum using something like prism. Different displays show different band of colors with something like RGB-LED having RGB bands very separated while sRGB W-LED displays showing more smooth transitions in longer part of the spectrum and distinct and bright blue band.

I strongly prefer CRTs. I think displays have gotten so complex that our reactions to them aren't understood.
Image of CRT is most artificial thing human eyes could stare at. LCD and OLED are much closer to reality.
Doesn't mean CRT must be more tiring as strong but momentary stimulation and then cones resting for most of the time staring at black screen might be better. Might but usually is not and it is rare people prefer CRT for eye comfort. It happens though. I find CRT more tiring than LCD. Even worst LCD were less tiring than using CRT for desktop.

For TV I do not have OLED so I cannot comment on them. I have plasma. They are like CRT in that they use phosphors and flicker. They also use dithering heavily which is both their biggest flaw and surprisingly great advantage. I love how games look on plasma when sitting very close to the screen, somehow.

W-LED was perfect choice for LCD panels backlight. It is cheaper to put bar of LEDs than manufacture expensive CCFL lamps with mercury inside then and which need failure-prone high voltage power supplies. Panels with LEDs can also be made thinner.

We use the same way of creating white in the current generartion OLED TV panels for the same purpose. It is cheaper to use this tech.
And also because we use this tech I do not want to jump on this tech. There is fortunately something that will replace this nonsense and it is called QD-OLED. They will still use blue OLEDs but red and green subpixels will be derived using Quantum Dots. Much less light wasted converting blue to red/green with quantum dots than converting it to white using yellow phosphor and then using color filters. OLED screens will get brighter with the same power output from blue OLED ==> at the same brightness they will live longer ==> less burn-in. Hopefully they will perfect this technology until I decide plasma is not good enough... probably when Playstation 6 comes out and games are actually in 4K and not 4k-wanna-be which look better on 1080p screen.
 
Film content which is I think 24hz looks so bad at times that I feel like I can count the frames.

But that's the wonderful "film look"! (It's actually not how film looks, but that's what people say). I've learned to stop worrying and love motion interpolation.

We are so used to it that being the way films look in motion that anything higher looks odd. E.g. if you watch TV series that are filmed at 30 fps they somehow feel worse. It's a weird phenomenon.

I watched I think The Hobbit in 48 fps in theaters and that seemed oddly smooth at first but then your eyes adapt and then it looked normal. It's a shame that format did not catch on.

Having used an OLED TV as a desktop monitor for over a year now, for me it has not caused any eye fatigue. Eye fatigue is such an individual thing that you can't say that X causes it or Y does not cause it, in the same way that some people (including me) feel sick playing games in VR while others are fine. Generally running at reasonable brightness is the most helpful thing for avoiding eye fatigue as most displays nowadays are capable of excessive brightness.

Have you tested yourself for display motion blur fatigue?

It doesn't affect everyone, but it's an ailment that occurs more often with ever-bigger-screens and for VR. Low persistence operation helps a lot of motion sickness and certain fatigues. There are definitely issues with other fatigues (PWM, gamut, blue light, etc) but motion fatigue is increasingly major due to the growing sizes and FOV of displays.

OLEDs have less motion blur than LCDs running at same Hz, but many OLEDs are not running in low-persistence operation like CRTs and plasmas are. MPRT is more than 10x bigger cause of motion blur than GtG is -- there are two different pixel response benchmarks, and non-strobed OLEDs have extremely high MPRT numbers (bad). Even the best strobed OLED TVs don't generally do better than 8ms or 4ms MPRT, unlike LCDs which can now do ~0.3ms MPRT when properly cherrypicked and configured to zero-crosstalk operations.

Display motion blur may not be your ailment -- people are also affected by PWM or by blue light or by stutters or by other issues -- but motion-blur-induced nausea and strains also exist. This is becoming a bigger problem with brighter, bigger, contrastier wide-FOV screens which amplifies fatigue from issues such as blur or stutter, etc.

There are counter-acting effects though. Stutter also causes fatigue. Reduced motion blur can amplify visibility of stutter. An additional unexpected factor is that faster OLED GtG pixel response can amplify visibility of stutter at the same frame rate. RTINGS actually measures the stutter amplification caused by fast pixel response, and determines if the display has low-framerate modes that compensates for this issue. It's why 24fps film sometimes weirdly looks more stuttery on OLEDs than on a Pioneer Plasma or on LCD. The phosphor gentle fade-decay on the plasma, and the slower LCD GtG attenuates the motion. This may or may not be desirable for people. One fix is to use a higher frame rate (e.g. 48fps HFR or 120fps HFR) but not all films are available in HFR, and not everyone likes that effect. If your stutter nausea is bigger than your blur nausea, adding a very slight amount of blur (slowing down the pixel response when playing back 24fps), it can reduce nausea. Everyone reacts differently to specific line-items (PWM, stutter, blur, flicker, tearing etc). Not everyone sees in quite exactly the same way.

Now if you only play 120fps+ HFR material (e.g. only play video games, not films/movies), your fatigue cause may be from something else than stutter/blur. However, even 120fps HFR material is much more motion blurry than low persistence operation (e.g. via strobed/ULMB or via 300-to-1000fps ultra high frame rate operation for concurrently low-persistence sample-and-hold).

MPRT(100%) blurring can never be less than frametime on a sample-and-hold display, which is a major MPRT bottleneck on low-Hz sample-and-hold displays, including OLED. The only way to lower MPRT is briefer frames. Either of higher framerate at higher Hz, or by flashing the frames (like CRT) to shorten visibility time per unique frame. One way or the other.

There are people that become fatigued by motion sickness, often need to upgrade motion quality to compensate for the bigness/betterness of the screen. The massive sizes of ever-bigger-screens, with the massive improving brightness and improving contrast, really puts motion quality problem blunt-force into your face with increased chances of fatigue. Stutters are bigger at the same frame rate! Blur is bigger at the same frame rate! All because of a bigger, brighter, wider-FOV screen. Here, there are many situations where 60fps and 120fps sample-and-hold often do not fix motion fatigue.

Option 1: Sample and hold method of motion blur reduction: Increase Hz & framerate
Upgrade your motion by increasing Hz and frame rate by a factor of 2x-4x and see if it helps. General Blur Busters recommendation is geometric upgrade curves (60Hz -> 144hz -> 360Hz -> 1000Hz) or via (60Hz -> 120Hz -> 240Hz -> 480Hz -> 1000Hz) to get the noticeable motion ergonomic benefits via strobe-free methods of blur reduction. As much as your GPU will allow.

Option 2: Strobed/impulsed method of motion blur reduction: Turn on strobing such as BFI or ULMB
Intentionally microsecond-precise synchronized impulsing (flickering) a display like a CRT to fix display motion blur. While it is a pick-poison method, it is a good kind of flicker that solves a worse evil (blur) for some people. Choose an OLED with as BFI feature that works at high refresh rastes, such as LG CX OLED with 120Hz+BFI available. Alternatively if you have to go LCD strobing, you need to do a few tricks to overcome LCD limitations. You want framerate=refreshrate=stroberate if using a low persistence technology such as BFI or ULMB or DyAc. If you try to strobe an LCD, remember to improve strobe quality and reduce your double-image-effect strobe crosstalk via refersh rate headroom. (strobe crosstalk is also a source of nausea for some). For example, the XG2431 can go zero-crosstalk be made to look a CRT at lower refresh rates such as 100Hz+QFT or 120Hz+QFT, despite being a 240Hz panel. If you decide to use an LCD, however it gets problematic for strobe quality at max Hz. Major LCD VR headsets such as Valve Index LCD or the Quest 2 VR LCDs do a trick where the panel scans-out very fast (like a 1/240sec LCD) with long intervals between scanouts. This produces more time to hide LCD GtG between refresh cycles, unseen by human eyes, for perfect zero-crosstalk strobed LCDs that only recently became available -- but you must cherrypick and configure them correctly. For top-class desktop LCD strobing, you want to buy more Hz than you need, and strobe far below max for the ultra quality strobing luxury. Now, that being said, the LG CX OLED can do BFI to as low as 4ms MPRT (achieving 60fps=Hz or 120fps=Hz material with roughly the same low motion blur of 1/240sec sample-and-hold), something the C9 and C1 series cannot do. Regardless of LCD or OLED technology which requires different tweaks, impulse-display tweaking techniques required to make flat panels look like a CRT (in perfect zero-crosstalk motion, zero double images) is very counter-intuitive sometimes.

Strobed OLED MPRT vs Strobed LCD MPRT
With today's technology, strobing currently reduces display motion blur more than increasing refresh rate does. Achieving 1ms MPRT requires 1ms frame visibility time. Eliminating the black frames means 1000fps 1000Hz to do "1ms MPRT" strobelessly on a sample-and-hold display. So the only easy way to achieve 1ms MPRT is via strobing, and even TV-size OLEDs don't yet go below 4ms MPRT despite being near-0ms GtG. Due to Talbot-Plateau Theorem and the brightness limitations of OLED, strobing an OLED will usually darken an image far more than strobing an LCD, since it's easier to voltage-boost the strobe backlight to compensate for brightness limitations during strobing (Maintaining hundreds of nits during 1ms MPRT). Also, some people blur fatigue is solved at 4ms MPRT so you will be perfectly fine with an LG CX OLED (not C1), while other people require 1ms MPRT or less for blur fatigue to be solved. However, 4ms MPRT is still very decent for most people, if you are able to run a LG CX OLED at 120Hz BFI at full 120fps frame rate -- creating a final 1/240sec MPRT -- for currently the best large-format OLED motion clarity without too much brightness loss and without objectionable flicker. YMMV.

TL;DR: There are two ways to reduce display blur, if you later find out you get fatigue from display motion blur:
- Increase refresh rate (and frame rate); or
- Add impulsed operation (like a CRT)


(...we know this, because Blur Busters ;) ...)

Most similarly sized LCDs at the same distance are better for me. I use plenty of bias lighting, and reducing blue light hasn't worked.

That said, if you use low persistence (strobed) operation with LCDs, make sure to get more refreshrate headroom to eliminate strobe crosstalk. 240Hz LCDs will have less crosstalk at 120Hz strobed (50% Hz headroom), than 144Hz LCDs do (<20% Hz headroom), as Hz headroom is needed to hide LCD GtG in VBI in dark between strobed refresh cycles.

For example, the XG2431 can be made to look a CRT at lower refresh rates such as 100Hz or 120Hz, despite being a 240Hz panel. Also, LG CX OLED can do BFI to as low as 4ms MPRT (achieving 60fps material with roughly the same low motion blur of 1/240sec sample-and-hold), something the C9 and C1 series cannot do.

(...we know this, because Blur Busters ;) ...)
This is an interesting take. I didn't realize OLED had bad MPRT. Just tested my Galaxy S8 and it wasn't pretty- 15.3ms.

Potentially, and this isn't based on much, motion blur might play into why I usually can't stand PWM flickering on blurry LED LCDs and OLEDs, but have no problem with flickering as low as 75 Hz on CRTs. It could be something like the CRT's motion clarity somehow partially nullifies the negative effects of flickering, where the blur of LCDs and (most) OLEDs exasperates it.
It's similar to how people on ledstrain.org talk about having eye fatigue with flickering on LED LCDs, but no problem with flickering on CCFL LCDs, due to CCFL flickering being less aggressive (CCFL bulbs taking longer to go from off to on than LED).

I have not yet tried OLED capable of BFI. If BFI helps solve my problems, it would prove motion blur is somehow a factor in my fatigue like you say.

I have a Dell XPS 9560 with a 4k 60Hz IPS screen, and you can cook a grilled cheese sandwich by the time a pixel has transitioned (40ms BtW and 57ms GtG, yes you read that right lmao). While the screen is fairly comfy, probably thanks in part to 0 PWM flickering above 20% brightness and high DPI, it isn't as comfortable over long sessions as the older laptops I had before it, either. I'd be curious to experiment with the tweaks you mentioned to see if they help.
I actually managed to overclock it to 334 Hz at 720p a long time ago. xD I'm not sure if it's frameskipping yet, and I'm not sure how to test it since BlurBusters doesn't work on Linux.
But, though the more noticeable thing is reduced input lag, 334 Hz is definitely a tad less blurry than 60 Hz on this display. So, it might be worth experimenting with in terms of eye fatigue. I already think I have an idea of a way to set up a blind test for it.

I've seen software for Windows that does BFI at the cost of input lag (unlike hardware BFI). Would be nice if something like it existed for Linux.

I am also leaning towards one of the culprits of my eye fatigue being temporal dithering or pixel flicker. If non-CRT low persistence displays still don't work, I'll keep more focus on dealing with pixel flicker.

We are so used to it that being the way films look in motion that anything higher looks odd. E.g. if you watch TV series that are filmed at 30 fps they somehow feel worse. It's a weird phenomenon.

I watched I think The Hobbit in 48 fps in theaters and that seemed oddly smooth at first but then your eyes adapt and then it looked normal. It's a shame that format did not catch on.

Having used an OLED TV as a desktop monitor for over a year now, for me it has not caused any eye fatigue. Eye fatigue is such an individual thing that you can't say that X causes it or Y does not cause it, in the same way that some people (including me) feel sick playing games in VR while others are fine. Generally running at reasonable brightness is the most helpful thing for avoiding eye fatigue as most displays nowadays are capable of excessive brightness.
I'm running my LG C9 65" using 60% OLED LIGHT setting, and most of the time I also set Energy Saving to Medium, to make it still dimmer in the evenings. I use the OLED TV as a PC monitor, mostly for web browsing and watching videos, and too much brigthness burns my eyes. For dark/low contrast videos, I turn off Energy Saving to see it better, and for some movies I might increase OLED LIGHT for improved experience.

Regarding video frame rate, due to OLED's fast response time/lack of motion blur, motion smoothing becomes more important. In particular, horizontal panning in anime looks especially bad. Without motion smoothing it's more like a slide show instead of smooth movement. But if I turn on motion smoothing on LG C9, it produces visual artifacts around subtitles - it's not very good at handing the edge between a moving background and stationary subtitles. I hope the algorithms get better in the future. I wonder if simulated motion blur would work as an alternative to motion smoothing. Or maybe BFI would help (I've tried it only at 60Hz and that was too flickery)

P.S. I used to get VR motion sickness in the beginning, so that I could play Dirt Rally or flight simulators only 30 minutes at a time. But nowadays I no longer get motion sickness. It's something that people can get used to, though it'll likely take many months.

I like OLED a lot more than LCD. The superior color gamut, deep blacks, and motion clarity in particular are all great.
However, OLED always seems to cause me more eye fatigue than LCD.
I've tried eliminating PWM flickering with transparent overlays or DC dimming. It helps, but not to a point of being as easy on the eyes as LCD, let alone how much it ruins color reproduction at low brightness. I've tried blue light filters, both glasses and software. Nope.
After switching to a CRT at my desk last summer, I've gotten a lot pickier. Gaming IPS LCDs have good colors, but the ones that are acceptably fast have terrible blacks and vice versa.
Still, my experience with OLED has mostly been with phones, tablets, and showrooms. Maybe I just need to try a LG CX for awhile.
Anyone else have issues with OLED?
Unfortunately all the OLED TVs based on LG panels flicker and in my case this also causes eyestrain and headache. Had to return an otherwise beautiful Panasonic OLED due to this.
The dips in the graph you can see in post #7 indicates drop in luminance. Seems to be the way these panels refresh so none of the TV's options affect the flicker.
It's pretty easy to capture the flicker using a camera and playing around with different shutter speeds. See attached gif

How are these newer Oled monitors like the Alienware 34"?? once the sizes come down with a good refresh rate I'll pick one up hope I don't have to wait around 5 years. Like waiting for Camelot Unchained to come out.
 
Yeah, all LG OLEDs flicker. If you want really flickerless monitor, you should look at IPSs.
Comparing my current OLED 42c2 to the prime IPS panel installed in the Predator X38, which really has no flicker, the IPS is certainly more comfortable to stare at. Although it loses all other merits, I wouldn't trade.
