If you are used to a more bluer white point then yes it will appear that way. Give it a bit and your eyes will eventually adjust.

50 OLED Light + 50 SDR Brightness should give you around 150 nits in PC mode. Setting OLED Light to 36 while leaving SDR Brightness at 50 will give you about 120 nits.
Note that the graph says "OSD Brightness" when it is referring to OLED light. It is recommended to leave SDR Brightness set to 50 and control how bright the screen is with OLED Light.
And bear in mind 120nits is an "enchanced" normal because most sets need it. In theory, 100nits is ideal. And I'm very happy in the 20s in a dim room. It's plenty bright and where I like it for reading and gaming.
HDR content is a different matter entirely.
But for SDR and desktop I can't imagine going over 30, or it starts getting uncomfortably bright for long reading sessions anyway.

desktop reading is totally different than media and images. I have dark themes and I can use a brightness slider addon "turn off the lights" on my web browsers too, which can leave images and videos untouched. (I also have a color changer addon with a quick drop down menu for background and text color wheels).
If I was using the OLED as my only display (rather than a dedicated media and gaming "stage").. with some work apps that had no way to be in dark modes I'd probably set up one of the named sets of inputs in the TV OSD just for apps/reading and swap in and out of it with the mic on the remote.
I would never want to use my lower "white-page" reading brightness levels...
... that I use with my addons (mostly for web pages what have a white background - if I don't want to use the color changer addon-on on them)
... as the same brightness (and color brightness) I use for media and pictures. They'd be too dull.
Same as if I am using an ebook reader on my tablet.. it would be set way dimmer in the e-reader than if I was viewing photos, art and videos outside of it.
Dark background themes and app settings work fine on everything else. I use a 3rd party file browser (directory opus) that has a ton of options. The aforementioned browser addons for both firefox and chrome, 3rd party notepad like app with dark background, 3rd party email app with dark background/theme, dark mode chat apps, streaming apps, youtube dark mode, slickdeals dark mode, etc etc. along with a high contrast dark windows theme.. you get the idea.

OK... I'm starting to think that there is something wrong with my OLED then...
Here are few photos of it set OLED light to 100. Total dark room, no lights, SDR Windows.
What you guys are explaining, in dark room, this OLED light set to 100 should blind my ass like a sun, right?
And still, I can read everything ok, even white Google page doesn't blind me - is pretty vivid, but not that bright...
Tell me why?

Only way to know for sure is to get a colorimeter and measure the maximum light output with OLED light set to 100. Sustained windows up to 25% are nearly 400 nits bright which is definitely enough to blind you in the dark (as well as accelerate burn in). Have you tried messing with peak brightness settings?

You want contrast at 85 and brightness at 50. Having those lower is doing weird things. Just adjust OLED light when you want to change the "brightness".
Think of ASBL increasing your panel life by another 3000-4000 hours if using it as a PC monitor. IMO it's not worth disabling it because of this. But I agree it's not ideal and probably a bit too aggressive. I don't really care much about it in desktop personally. It's mostly annoying when it triggers in media. It even happened when I was watching Kingdom last night. Your call whether it is worth disabling or not.
It looks really bright to me from your photos. OLEDs naturally look dimmer than backlit LCD, because LCD literally has a flashlight shining to illuminate the entire screen regardless of each pixel value. Whereas OLED illuminates per pixel, so the overall brightness will change depending on the content you're viewing. You are used to super bright screens it sounds like. It will probably take a while to get used to it but you should turn it down.

I think it must be me then - sounds like you're right - I'm used to overall brightness of LCD screen, sitting 50cm from 40" VA panel for last 5 years.
Now, sitting 50cm from OLED I see only brightness from pixels, not the whole screen, so it feels like its dark.
Keeping OLED to 30 (20 even), Contract 85, Brightness 50, color 50.
I need to get used to it now.
ABSL isn't bothering me ever, with brightness 20-30 in SDR. I've not seen it happen in a game or video, only on the desktop when leaving a static window for a little bit (I don't do work on this display so don't care). Only way I can make it happen in a game is by leaving a mostly static menu open, or finding a scene with practically zero motion and not move the camera at all (aka be AFK). Of course pausing a video works too.
That's a good thing though, means if I forget to toggle the screen off when walking away for a few minutes it will mitigate the damage.
If you have a low OLED light setting to begin with, it's probably not too bad to disable it anyway. Should not make much of a difference in the long run.

Can anyone help me?
Lg says it's normal
I think if you're mostly just gaming or watching content it can make sense to turn off ABSL - it can be really obnoxious sometimes and isn't doing much anyways to protect your screen in those instances.
I've never heard of this... How would the screen be swollen in the middle? It's a flat piece of glass. It sounds like an obvious defect to me if so, though. Do you have pics showing it?

Just disable it. You will not regret it. Thank me later
I used to be the same day; you'll adjust after a few days.
There is no point in running it in anything but Game mode when connected to a PC. That offers the lowest input lag and if you just copy the settings from Expert (dark) you will get very similar image quality.
If you want you could just hook up another HDMI input to your GPU and set that to use different settings with instant game response disabled on that input. But IMO it's not worth the effort.
For streaming services I would just use the built in apps which can all have their own picture settings.
ASBL is awful if you do use it on the desktop. It will gradually dim the display all the time and often it can be hard to get it out of that dimmed state without showing a big white window to it. Disabling it from the service menu made it just much better, I don't care that it will reduce its lifetime a bit. I have a blank screensaver set to turn on in case I forget to turn on the display when I take a longer break.

Guys, is there a setting I'm missing to make text look better?
Its almost ok, but on dark backgrounds I can see this "shadow" or double letters kinda thing.
Hopefully this photo shows it - look at the d letter.

I believe this is an effect of ClearType on Windows combined w/ the WRGB subpixel layout. There are various hacks to minimize it if you search around for color fringing on an LG OLED. Also make sure you are in 4:4:4 chroma.

Get Better Cleartype Tuner, set it to use Grayscale antialiasing and restart the computer. That's IMO the best thing for Windows text rendering on these displays. Disabling Cleartype works but IMO looks crap. OSX is far better with the way it handles no font smoothing.
Also make sure you are running 4:4:4 color space. This requires that the icon for your TV input is set to PC and RGB is selected in Nvidia Control Panel settings or the same thing on the AMD equivalent.

Wait, what do you mean by 4:4:4 - I thought Nvidia panel needs to be set to YCbCr444 - should it be RGB? If yes, how am I gonna set it to 444?

I'll also add.. don't sit too close to it. I had a 32" 1440p and the text and anything else would show edges if I tried to sit 1' to 1.5' away. When I sat at a more appropriate distance for it's ppi .. it's PPD and default font sizes looked great. Also in the same vein, don't try to make the fonts smaller than the ppi's limitations just because you are sitting too close as that will be worse too.
THX 's standard has optimal viewing angle for movies as 45 to 50 degree width. On a 48" 16:9, 50deg starts at ~ 44.4" screen to eyeballs. This results in ~ 76 PPD.
That's for movies though, to see the whole scene. It's a good baseline but I sit closer for some games at 38" to 41" away. I wouldn't bother sitting closer than that (and then complain about the ppi and font edges).
The PPD at that THX 50 degree is the same as what the ppi would look like at all of these monitor sizes at these distances below. For general usage and gaming I would sit closer (putting a little more of the scren's extents into the periphery) but this gives some idea of the distance ratio between all of these screen sizes PPD wise at ~ 76 PPD.
You can adjust that tool to compare nearer.
e.g. 54 degree viewing angle and the same ~71 to 72 PPD at 4k on all of them at those distances would be:
48" 16:9 display = 41" view distance ( ~ 3.5 ' )
42" 16:9 display = 35.9" view distance ( ~ 3' )
31.5" 16:9 display = 27" view distance ( ~ 2.4')
27" 16:9 display = 23" view distance ( ~ 2')

what is the best way to clean the screen?
https://www.lg.com/us/support/help-library/cleaning-your-lg-4k-oled-or-led-tv-webos-CT10000020-20150154791049#:~:text=Cleaning your 4K, OLED, or,may not be too late).
Only a microfibre cloth according to LG, no water or anything.
Personally I have a small spray bottle of distilled water+light cleaning fluid, advertised for TVs/screens/lenses, that I spray onto a microfiber and use that. And very lightly clean the screen. Scratches come from pressing too hard when cleaning, which is likely to happen if you don't use any cleaning agent at all cause it's hard to remove some stuff.

Thanks. I have a microfibre cloth but will need some cleaner as well. What cleaning fluid do you suggest? I have anti-reflective glass cleaner that I use for my glasses. Mix that with distilled water?

Yes you can just set it to RGB. This gets you 4:4:4. YCbCr444 does pretty much the same thing, all that changes is where any possible conversion happens, the end result is the same.
Do NOT use glasses cleaner - they usually have alcohol in them. Which will strip the coating of the screen.
If you have distilled water just use that, you should be fine. Only use liquid if you can't easily remove with just a dry cloth.
I use this stuff: https://www.amazon.co.uk/Ecomoist-Natural-Screen-Cleaner-Microfiber/dp/B00DX7GLW8/ref=sr_1_5?crid=2VMAVCCRN2NRG&dchild=1&keywords=ecomoist+natural+screen+cleaner&qid=1610732097&sprefix=ecomoist+n,aps,149&sr=8-5
Mostly because I had it on hand for my iPad, and it's not easy to get distilled water in the UK.

There is no solution for the text. The OS doesn't have control over the white sub-pixel and can never anti-alias text properly on this panel.
His text looks a lot worse than mine. I don’t have the green fringing. Try the cleartype tuner if you haven’t already.

That pic he took is from very close to the screen though too. How far away is he sitting? Sitting too close in reltaion to ppi = a lower PPD so will always look bad. (Using text sizes too small in relation to the ppi will also look bad).
...27" 3840x2160 at 2.0' away is 73.5 ppd (and 53 deg horizontal viewing angle)
...48" 3840x2160 at at 42.5" away is 73.5 ppd
...27" 3840x2160 is 57.9 ppd at 18" (1.5') away
...48" 3840x2160 is 57.9 ppd at 32" away
Same goes for sitting too near at a desk for 1440p on 31.5" 1440p diagonal screen like the VA I upgraded from, and it's why VR resolutions are still an issue currently (even though they use lenses to change the focal point).

hey all, I installed one of the desktop clearing apps as recommended in this epic thread, so that my desktop is pure black. I am not finding the trashcan via searching in Windows and I need to empty it. I am used to doing so from the desktop icon.
Can anyone explain how I can access it now? Thanks.
