If response time is paramount this is a bit better than the Sony TVs. The picture quality from the Sonys is better and I believe the Sonys don't use PWM dimming, but I could be wrong on that. I think the Sonys also have some limited 120 HZ at 1080p capability.

Also, if the PIP, PWP, and KWM features are useful to you, this is much better than the Sonys.

The other 40+" monitors out there are all worse or similar to this.

Thank you for the information. I'm sorry I'm a bit of a display noob. I guess PIP = picture in picture, but what is PWP and KWM?

I don't game a lot, but the LG's GTG response time is 5ms whereas the Sony's is 12.8ms. I've never played on anything over 6-7ms, will it be very noticeable? I'm not super competitive, but I play some Overwatch and StarCraft. Also, the input lag of the Sony is 34ms for 4K 60Hz HDR, isn't that pretty bad? I'm not sure what the LG's is, they're never listed for monitors.

When you say picture quality is better on the Sony (I assume you mean the IPS version), do you mean in terms of color accuracy? That's somewhat important to me. Also, which has better blacks and less backlight bleed / near-bezel color shift?

Finally, which has better speakers? I will be using the speakers mostly for watching youtube videos and such, so they need to be decent, but not amazing.

I'm reluctant to get a TV in lieu of a monitor because I've never done that before, but if the Sony is noticeably better, then I will go with it. Thanks and sorry for the barrage of questions.

34ms Input lag is horrible. For a 60hz panel, you want under 16ms input lag or you get more then 1 frame of lag.

Regarding response time, it's all bullcrap. Monitor/TV manufacturers should be sued (lol) for all their false advertising in this area. You have to look up independant reviews by professionals who use oscilloscope and other photo sensors to determine the real response time. Ever noticed how every single TN monitor says 1ms? and every IPS/VA says 4-5ms? It's all complete bullcrap, they say 4ms average but in reality it's 12ms, with some pixel transitions taking 20ms and others 8ms. Things like BenQ blp3200 says 4ms but in reality average 16ms with max of 40ms.

The Sony X800D has a VA panel which means there is going to be way less backlight bleed (on average, I never seen a VA with loads of orange) and no gray IPS glow (eww on TV size), which means it looks better in dark scenes. However the negative of this, VA panels often have slower pixel transitions in dark scenes and if it's too high, can cause smearing (aka looks worse then traditional blur). I prefer VA because IPS has that horrible glow in dark scenes, but VA is also hit and miss if your a gamer due to the response issue.

Anything over 27" right now is hit or miss for gaming.

Thanks. I was considering the IPS Sony, as I prefer IPS to VA. But the response time and input lag points you raised have got me thinking I should probably just go with the LG. Kudos to people who make TVs work as monitors, but I feel like there's always some major compromise. This LG is definitely not perfect. But it's better than the Dell. I wish Dell would release a premium monitor in the 40-43" range.

I just want a 40-43" 4K OLED 120Hz HDR, 100% Adobe RGB, G-Sync monitor, why doesn't that exist. :D
 
"I prefer VA because IPS has that horrible glow in dark scenes"

You know, the color and contrast shift in VA panels is inadmissible drawback and has always been a deal breaker for me. Limited and inaccutate color representation and so on. The positive sides are not enough to justify this. And finally IPS panels are the most expensive technology in LCD screens, even tough they ditched the S-IPS displays - the best LCD displays ever created, and did this out of financial considerations.

Some people keep saying this but I have a TN in my lounge room from 2008 that has zero glow, zero blb and looks fine even far away. Yet the IPS i'm sitting right infront of right now has a white area in the bottom left and I got lucky, an ultrawide IPS i had before it it looked like someone was shining a yellow torch in the bottom left and a white one in the bottom right. Even the 28" 4k TN I had was excellent, it's not like Im going to be sitting on the damn floor or on a 45 degree angle, the only time it looked a little dark at the top was when I sitting so low it was ridiculous.

I recently tried a $400 AUD 32" VA monitor and it was amazing quality. No BLB, no glow, could stand anywhere in my room and it looked excellent, only downside was the respones time was horrible it smeared everywhere.

I also bought an IPS tv once. my god that was bad, the off-axis gray glow was insane it made Alien look like some washed out garbage.

The only IPS I actually like is the AOC AGON ag271qg and I got mad lucky with that panel, and it cost $900....

If you have that much to say about VA being bad, you must really hate TN... O_O

on lg site they claim its gamut is 72% NTSC. 72% ntsc means 100% srgb, isn't it?
I'm looking for a big monitor for watching movies on streaming and editing my photos/video. 100%
of srgb is the minimum for me seen that wide gamut big monitor are too expensive for me now
 
Fry's has this monitor for $578 /w promo code. It's in the weekly circular. No ship obviously. I think the deal ends the 16th.

PWP was supposed to be PBP which is picture by picture, which is a screen split. KWM = Keyboard Video Mouse. This is the function of the monitor that allows you to hook up multiple computers to the same monitor and control them using the same mouse and keyboard.

I didn't notice anything painful in FPS games on the LG. The input lag on the Sony is likely noticeable in FPS games, but its very dependent on the person. 34 isn't so high as to be unplayable for most people.

By picture quality I mean that the contrast is better on the VA Sony panel and I believe the IPS Sony has a wider color gamut than the LG. The Sonys might also have better subpixels, which would make text clearer. I also presume the Sonys won't have the edge shadows that the LG does.

The speakers on the Sony are likely better, but I used the ones on the LG and they were perfectly acceptable for watching videos and such.
 
most of youtube videos are still 480p. One question for who own this monitor, how do they appear?
thanks
 
I've had my monitor for about a month using it 10+ hours a day. Ask me anything (as long as it's not too much work for me to answer). :)

I am overall very happy with the monitor. The only issue (which isn't much of an issue) is the issue other people have also mentioned, that the monitor occasionally flash to black for half a second. It hasn't happened more than once per day so far though. The monitor may or may not have PWM but it is nothing that has bothered me so far (maybe I am not as sensitive as other people) My previous monitor was a 2233rz (120hz monitor).
 
"The monitor may or may not have PWM"

Well, it has PWM and there is proof for that. That`s the cheapest dimming method and given the price it`s understandable, but the LG guys write everywhere *FLICKER SAFE* which is a bold lie.

Agree that LG shouldn't be misleading people but I don't see flicker even at %20 brightness.

I wouldn't let PWM keep you from buying this display unless you know you have a sensitivity to PWM.

I don't see the dark bands at a reasonable viewing distance either. I see them if I get close and get the angle right. I couldn't imagine using this display so close. It's too big.

Given the price, I think this display is an great placeholder until 40" 4k FALD HDR 144hz monitors are a thing.
 
Don't you guys find such big monitors hard to use for computer use, say gaming with keyboard etc?

Oh, sure, I didn't mean to say that they should get away with lying. All I wanted to say is that whether or not it has PWM, it's nothing that has bothered me in my use of the monitor.

Surprisingly no. I was against such big monitors for a long time, but I decided to pull the trigger for this monitor anyway since I am going to be using it primarily for productivity (instead of getting a multi-monitor setup). At a proper distance the size really doesn't bother me and it also works fine for non-competitive games (I played a fair bit of GTA V).

You're right. 43 inches is too big. Ignore the fact that every other thread in the display forum is about looking for a good 40+ inch 4K display. :angelic:

Lol. Yeah, people have been asking "isn't that too big to use as a monitor?" for years now. My first large display was the Westy 37" that was so popular years ago, and it was a game-changer in terms of immersion. Today, with 4K becoming mainstream, the case for a large monitor can be made even easier since 4K is so difficult for most people to use on smaller displays if they don't want to use scaling.

I think the 43" displays are in the sweet spot for me personally, in terms of size. My Samsung 48" is just a hair on the large side, which is unfortunate because the only thing stopping me from getting an OLED is the fact that I currently can't seem to find one smaller than 55" (aside from the very short-lived Dell 30" OLED monitor). And OLED makes all of these little side discussions where people argue the merits of IPS vs. VA, etc. moot as it supposedly blows ALL traditional LCD tech away in terms of IQ.
 
The only problem I have with 40" is the lack of aftermarket stands and mounts. Seems like everything is for smaller PC monitors or much larger TVs.

There are a few arms suited to the 40" class but I don't like arms. My display is sitting on a plastic step-stool as I continue to search for a stand. Ghetto as hell.

It's easy, I just assume you and everyone else is just crazy. Dunno if there is a big monitor that size with the boxes ticked. e.g good response time, good input lag, no pwm for starters. I know the Philips everyone loves has horrible smearing.

Click to expand...

I've been doing it off and on sense like 2008, todays TV's are definitely more forgiving than LCDs from back then but end of the day TV's are designed for a different purpose so not as much emphasis is put on some things like uniformity and input lag mostly. as for the X800E specifically I'm quite happy with it for my uses but I'm sure there would be people that are not. So far I have noticed a number of relatively minor issues with using it close range as a monitor.

the most apparent issue and this seems to be a common one with any display this large up close that is flat is the edges appear dim on white screens esp far left and right edges, its a viewing angle thing as if you move your head side to side it goes away, its not really apparent outside of all white full screen windows.

it has black uniformity issues with all black screens that appear as large vertical bands or waves if you will, once again only really apparent with completely black screens (like say when i'm booting my PC etc)

I have noticed in one game so far quite a lot of pixel blurring with the right conditions, Arma 3 near nighttime in the woods so lots of green grass blades, when i moved the pixel blur of the light dark green was very visible to me. interestingly enough this is the only scenario where it has been this noticeable to me and at this point a few months into ownership i've played a fair amount of games on the TV.

lastly for those who care about input lag, its got input lag for sure. if you get it stuck into the wrong picture mode or resolution input it becomes very noticeable but as long as its getting the right 4k input It hasn't been enough to bother me personally but people that are more sensitive might find it to be too much.

All in all considering my uses these days I'm still very happy with the TV, I mostly use it for desktop use, TV and Movies and these days i'm definitely much more of a casual gamer looking for great graphics and single player over being a competitive multiplayer person like i used to be when i was younger so it fits the bill for me.
 
^ And the thing is, many of the downsides that you mention can affect monitors as well. I've had several "gaming" monitors with banding, blurring, and uniformity issues (not cheap no-name monitors, either).

Input lag and lack of proper chroma subsampling were, at one point, some fairly big drawbacks of using a TV for a monitor but both of those things have been improved on many sets to the point of being a non-issue to all but hardcore twitch gamers. The tech has improved and it's no longer difficult to find a TV that serves as a great monitor, which is a good thing if you're in the market for a large display since there are still relatively few 40"+ monitors and the ones that exist tend to have some unique issues as well.

With the proliferation of 120 Hz+ gaming monitors, I would say one of the biggest drawbacks for a gamer using a monitor as a TV is that you're going to be stuck at 60 Hz in most cases. I owned a 120 Hz gaming monitor by Samsung and I sure would love to have that level of smoothness and motion clarity on my Samsung 48" 4K, but it's not a dealbreaker. For me, a large immersive display is more enjoyable than a smaller, faster one. Though I hope that one day a 40"+ 4K 120 Hz+ monitor will exist (do current HDMI/DP standards even support that much bandwidth?).

My next move is very likely to be to an OLED TV like the LG, since pretty much everyone who has gotten one says the image quality is a total game changer and whatever drawbacks might exist aren't enough to make them even consider going back to traditional LCD technology.
 
Indeed many of the drawbacks can be found in even high end PC monitors and you are correct the biggest difference at this point in time is lack of native high refresh TV's that will take 120+ hz input at higher than 1080p res.

I used a TV as a monitor for around 5 years. My biggest complaints were:
  • missing/crappy support for non standard TV resolutions (anything other than 1080p / 2160p)
  • slow to recognize resolution changes (takes so long you never see the BIOS on reboots)
  • lack of power management (remains fully powered up even when PC shuts off video signal)
  • slow to power up
  • no displayport input
  • need the remote control to do stuff
  • no physical power button
I use a real monitor now am I'm very happy I made the switch.

I still use a big TV for couch gaming. Doesn't bother me as much there because of the way I use it. I sit down, game for a long time, turn off, go do something else. When I need to work on the PC I bring it over to my real monitor. No more missing BIOS screens.

A lot of those points vary depending on the TV

on the X800E specifically

resolution issue hasn't been a problem at all it has displayed everything i have thrown at it including the bios of course, it is slightly slow to take the signal for the bios but not so slow i will miss it.

lack of power management i encountered in the past but with the X800E it will turn off after loosing signal from the PC after whatever set time i tell the TV to.

slow to power up, not really unless it needs an update (android tv) then well yeah gotta play the update game but on the typical nope, i in fact turn on my PC first then my TV normally and still see the bios screen.

no displayport, of course no displayport but HDMI is just as capable and there are adapter cables if one needs to use them they are after all almost the same exact thing.

no physical power button - varies by model but most do but yes the remote is more convenient to use in the majority of cases. the X800E has a physical power button but its definitely not easy to find or use instead.
 
Lack of displayport is a big deal if you have more than one PC. 60hz 4K HDMI KVMs don't exist. You might be able to use an active DP to HDMI converter to drive a TV from a DP KVM. I asked about that in a different thread and got 0 answers. Seems like a gamble to go that route without proof of someone else doing it successfully.

Actually, I don't see anyone else posting this, but one of the biggest drawbacks of using TVs as monitors (at this size) is the lack of "Picture-by-picture" aka the ability to tile several INPUTS into your display. That's HUGE for a big panel like this… You can basically set a TRUE multi-display configuration in a single panel, completely borderless. For example: you can set a single 3840x1080 strip at the bottom, and 2x 1920x1080 at the top… That's basically a triple display setup with a single display. That difference is PRICELESS between a TV and a big panel monitor…
 
Thanks for the replies, everyone.

Getting ready to purchase this: Reason is i want productivity at 4k and gaming at either 4k or 1440p
  • I want a monitor where i can game at 1440p (since at 4k FPS might be low on some games based on my graphics card and cannot do that well with a TV): Is this true? Otherwise i could consider the Sony X800d

  • I am not that sensitive to PWM (currently i have the Auria 1440p monitor but keep it at peak brightness; still has some PWM i.e. multiple lines in the UFO test but not as bad as lower brightness):
    • So can i keep this monitor as peak brightness? 350 cd/m2 is bright but not that bright i think
    • How is the pWM above 75% of peak brightness and above


  • Lastly, i really wish this can be made freesync capable: Does anyone have any info if there will be a firmware upgrade coming out soon and the HW itself can support that?

So finally, are there any alternatives based on my requirements other than the Korean monitors (ha ha i have one so should not shy away from them.. but just asking)

It runs fine at 1440p.

%100 is too bright in my opinion.

I don't see PWM at %35. I'm not saying PWM isn't there just that I don't see it.
 
Phillips just announced a 43" 4k HDR monitor at IFA, I believe it will be using a newer panel, which hopefully will have less shortcomings and no PWM.

I returned a 43" 7500 series Samsung recently because even with the curved screen the edges were color shifted due to the angle I viewed it at and the VA screen. Otherwise it was great, but the color shifting on the 3-4 inches on each side was too unpleasant. This being an IPS panel won't have the same issue.

This panel is only 60HZ though so I think Freesync won't matter unless you're gaming at 4K with high settings and can't maintain constant 60 FPS.
Click to expand...

I use a Wasabi Mango UHD400 myself, FreeSync makes a huge difference even at 60hz just to throw my input out there from experience. I didn't know if I was going to be happy with the lower performance with my new Vega 64 compared to my 1080 ti, but the experience is much smoother with the Vega hands down. The trick is to completely disable v-sync and use AMD's frame cap at 59 fps, say goodbye to input lag and tearing at the same time.
