I don't think it should. I run the CX48 with 2 4k monitors works fine I don't see any really FPS drop compared to benchmarks.I'm planning to use the LG CX 48 + 27" 144Hz IPS monitor on the same GPU (GTX 1080 atm, 3080 in the future). Does anyone know if this will reduce fps? If it does, how much in general? Thanks.
I have a 144hz 1440p Gsync monitor and a 60hz 1080p monitor connected in addition to the TV. I don't get any difference in benchmarks with them connected or disconnected...but if I have the 1440p monitor at 120hz my 3090 never clocks down from 3d clocks and is about 50w more power at idle.I'm planning to use the LG CX 48 + 27" 144Hz IPS monitor on the same GPU (GTX 1080 atm, 3080 in the future).

Typically it doesn't, but it depends what you're doing on the other screen. If you're watching videos or something while playing a game it might. If you just have a web browser showing a static page or discord or something like that it doesn't matter in my experienceI'm planning to use the LG CX 48 + 27" 144Hz IPS monitor on the same GPU (GTX 1080 atm, 3080 in the future).

Thanks everyone. Yeah, I'm just gonna use it for Discord, sticky notes, hwinfo, and other static info.Typically it doesn't, but it depends what you're doing on the other screen.

This is what I use.Didn't someone create a wiki that collects all the best advice on configuring/using this TV? I thought I recall reading that way way back in this thread. It would be super to have a link if anyone knows of this. This thread is way too long to easily extract the best advice from.
Use the RTings white balance settings also unless you calibrate.Bookmarked. Thank you!
OK thanks, noted. The monitor should be arriving on Monday or Tuesday so I will dig into set up then.Use the RTings white balance settings also unless you calibrate.

GeForce Hotfix Driver Version 460.97 is outThe hotfix addresses the following issues:
With HDR enabled, black levels are incorrect. 
Anybody already tested if its realy fixed ?
Wow! Cyberpunk is on another level now that the black level is fixed. Looks fantastic.
I upgraded to 03.21.09.Some guy on reddit said the new fw 03.21.09 fixes the raised blacks/flickering greys on HDR/Dolby Vision and VRR raised black/flicker issues! Anyone can confirm?
Hotfix 1.05 just announced with "Added some warmth to HDR." in the patch notes. We'll see WTF that actually means when it drops for PC.To be clear, this doesn’t fix the separate Cyberpunk HDR black level issue as far as I can tell. It fixes the relatively minor black level problem on the nvidia side but regardless HDR in 2077 still has grey blacks and looks like it has a grey filter over all the colors, due to it being derived from a scaled SDR image. Right? I hope I’m wrong, only tested for a minute and couldn’t get to an obvious problem area.
When you turn on Screen Shift, it only takes effect after the first timeout delay. This behaviour changed on an earlier firmware.I checked it by toggling screenshift on and seeing that there was a change. Previously when it was broken it would show off, but you would turn it on and nothing would happen, then when you turned it back off you'd see a change.
You still see the screen flash when enabling/disabling it. In previous firmware when it was bugged on but showing off, you saw no flash when turning it on (because it was already on) and then a flash when you turned it off.When you turn on Screen Shift, it only takes effect after the first timeout delay. This behaviour changed on an earlier firmware.
https://github.com/bradgearon/hdr-switchIs there a faster way to turn HDR on and off in Windows besides right clicking the desktop and going to display settings? Would be cool to have a shortcut pinned to the start menu or quicklaunch on the taskbar.
What HDR mode and Max brightness / Midpoint are you using ?Wow! Cyberpunk is on another level now that the black level is fixed. Looks fantastic.
I’m also curious what other people are settling on. So far the following looks best to me:What HDR mode and Max brightness / Midpoint are you using ?
now you can call hdr_switch_tray while it is running (in the tray) with a paramaeter 'hdr'
Just got my CX and thanks to this message i finally understood that my CX was displaying HDR even if it was stating 8bit...
Is there any way to know when there is a 10/12bit source from the hidden menu for 24hz?
how come the CX can display the correct info,12bit for the PS5 but not my shield!?
30 on the slider is still quite bright. 7 is more like 120nit.Cool options. It's nice that it can be triggered with scripting
That way I could set it to a streamdeck key to toggle it on and off if I wanted to.
Like a lot of other people in this thread, I've instead been leaving HDR on in windows 10 all the time. You just turn the HDR desktop brightness setting down very low in the extended windows hdr color settings until it looks like SDR levels. I think someone measured that a setting of 30 on the win10 HDR color brightness slider is equivalent to 120nits but you can easily be comfortable using a lot lower than that.
Active HDR content still switches to full 100% brightness range capability for HDR, with the HDR overlay flag popping up when it kicks on. So having desktop HDR settings color brightness slider turned down to SDR levels does not affect the active HDR metatdata content of movies or games ability to use the full 100 brightness range (~800nit) of the display so you still get the full HDR capability that the CX is capable of. I've had that slider zeroed out before and it would have otherwise made games and movies look dim and bad if it translated to them. Full screen HDR content's metadata is based on absolute values , not relative values (though displays do have to further tone map due to brightness range limitations of current displays).
Earlier, I posted the formula to calculate the slider value for any desired brightness in nits.30 on the slider is still quite bright. 7 is more like 120nit.
Make sure you have dynamic tone mapping set to HGIG for any game with a peak brightness calibration, I was doing this wrong for a long time, because the settings are named oddly. 350 peak brightness is really low.Best solution I've found for the Cyberpunk HDR black level bug: tweak shadow level and gamma in the Geforce Experience overlay. I've messed with it a lot and IMO this gives the best picture compromise without having to mess with TV settings just for this game. I have it set to the following right now with the newest hotfix driver and it's pretty decent. Blacks are black, highlights are bright, colors are not washed out.
Tone mapping: 1.75
in Geforce Experience Brightness / Contrast filter:
Shadows at +15%
Edit: adjusted brightness to 350 and tone mapping to 0.55 with same shadows and gamma since it way overexposes in bright daylight conditions otherwise.

Dynamic tone mapping on - This one makes sense. Dynamically every frame, the brightest part of the scene is assigned the peak brightness the display can do, and the rest of the scene is scaled accordingly. This can make parts of the scene change brightness that shouldn't if one spot on the screen goes from say 1500nit to 10000nit and the rest of the scene stays the same. Even though the rest of the scene didn't actually change in the signal, it will darken in the frame with a 10000nit spot because it is proportionally way less than 10000nit.
Dynamic ton mapping off - This is the one that threw me. The "off" part refers to the "dynamic", not the "tone mapping". "Dynamic tone mapping off" = static tone mapping. Everything in the scene 4000nit and above is assigned peak brightness on the display, values 0-3999nit are assigned brightness proportionally to where they fall between 0nit (OLED black) and peak brightness (something like 850nit on a CX). What this means is if you properly configure peak brightness in a game to 800-900nit like the TV can handle, you're actually only setting a peak brightness around 200nit because the tone mapping is being scaled with 4000nit as the peak.
HGIG - This is "tone mapping off". The TV will display exactly the signal it gets, any part of a scene that's brighter than it can display is clipped to the peak brightness of the display. So if you're in HGIG mode and send a frame that varies from 1000nit-10000nit brightness, the entire screen will be the same color/brightness solid white because it is all being clipped to peak brightness. But if you can tell a game via calibration settings that your peak brightness is 800-900nit, the game won't send any frames with brightness higher than that, and your TV will display exactly what the game is sending. That's why this is what you want if you can set peak brightness in a game.
Acording to HDTVtest you will get best result with playing it in SDR.Yeah, I've been messing with it since I discovered the Geforce experience trick .. never installed it before. Set brightness to 750, tone mapping to 0.85, shadows to +3 and gamma to -12 and it seems pretty solid. Already had DTM on HGIG mode.
edited: ok, patch 1.05 just went live and there's a major change in how HDR is output ... completely stops the filters from working well. Will have to check out if it can output black properly at night.
I have to say I'm pretty impressed by everything I have run across about this.
I have one probably very stupid question. Here is an OLED (pretty new tech) great specs, etc. and at these kinds of sizes... how in the world is this 48 incher more or less the same price as my 27 inch Asus ROG Swift PG27UQ? Supply and demand?
