Has anyone had any success with custom resolutions for higher refreshrates, such as 144Hz 4k, or 240-480Hz 1080p? I tried a little but it all just fails. Really a missed opportunity for LG here, this is for sure the best monitor for 4k120, but it couldn't have been that hard to let it accept 240...

It somehow glitches so gsync is still running. Can confirm It worked for me too. The TV reports VRR on, BFI (truemotion) is grayed out, etc. However, without any workarounds, 4k 120 10bit 444 Limited simply works for me, no glitching needed. OLED55CX6LA .26 firmware. RGB full doesn't and...

I have a EU unit (OLED55CX6LA), the .26 firmware was up briefly on the lg uk site.

That is already fixed on .26 firmware with 4k 120Hz 10bit 444 limited. (rgb full 10but has the stuttering issue - but also more banding, so 444 limited might be preferable either way unless they also fix the rgb-full banding in later firmware as well)

What we call sdr (and the srgb colorspace) were standards created with the limitations of the CRT technology. When other technologies like LCD and plasma started popping up, while they were capable of wide gamut, higher brightness etc, they still had to adapt the old standards based on the CRT...

Spent some time to tweak the settings for minimal banding, using the spears munsil video and the lagom.nl test image. First off, the sharpness setting causes banding. Very obvious effect, just turn it up and down with the test image/video. (needs to be set to 0 - lg's presets are often 15-25, so...

I'm just curious if you really have oled blacks over 51 brightness? I don't. 100 contrast 52 brightness for me kills blacks. 100 contrast 51 brightness still has oled blacks. (and to be very precise, if I turn the room pitch black, and set a full black screen, 100 contrast 49 brightness is the...

Do you still have oled blacks at 60 brightness? If so which model? Or do you sacrifice the blacks for calibration? I also run 100 contrast game mode (this seems necessary to mitigate black crush), and then brightness 51. brightness 52 and up no longer provide total black on my 55cx, but rather...

Vsync can't to my knowledge do large range vrr, no. Very few would ever have bought a single g-sync monitor then. But i tried to disable v-sync, and that changes the mode from VRR to fixed and hides the VRR option in windows (and to even turn VRR back on again, g-sync needs to be turned on...

That was over a year ago on an older build. That's not what it says or does now. 16 months and one major windows build and several smaller windows builds ago, or so :D I made a video, with a pattern that would easily show tearing. It is also perfectly smooth, but i guess thats hard to see in...

Nope, it 100% works, and nowhere in the setting itself does it state what you claim. frame limited 100 or 110 or 115 fps would've had stutter and/or tearing and it has absolutely none.

I am sure that I am running with v-sync on and as mentioned frame capped to 100, or 110, or 115 or 118, and all these framerates are smooth, tearing and stutter free.

I think I found a mode that actually works, and I also suspect explains why some people can uncheck the "enable settings for the selected display". If windows VRR is enabled, that probably kicks in when g-sync is turned off. and windows VRR actually seems to work perfectly. when you disable...

"This update will not, it seems, be available for roll out quite as quickly as the update that fixed the previous RTX 30 issues; LG’s response suggests that it hopes to have the ‘stutter’ firmware in circulation before the end of the year. " Anyway, since 4k 120 8bit 4:4:4 g-sync works I'm not...

This seems correct. So I have 3 options currently on the .26 firmware: 1. 4k 4:4:4 120 8Bit g-sync on amd freesync off. Seems more or less flawless in functionality. 2. 4k 4:4:4 120 10bit g-sync on amd freesync on. Needs framecap around 105-106, stutters at higher fps and the functional range...

Didn't work for me, but I'm on the .26 firmware. Only thing that works for me is freesync on in tv settings and fps cap 106.

Did you try the different hdmi ports on the gpu too? I read someone on reddit only had one functioning hdmi 2.1 or so.

I can simply select 10bit rgb with no issue with 4k 120Hz on my 3080, and hdr works. maybe properly clean driver reinstall, if you haven't?

and if you enable amd freesync?

So i thought id try every combination with the above status window to see what it says, and with instant game respone+amd freesync turned on + gsync in nvcp, it actually seems to work? Didn't have much time to try so please reproduce. (still maxes out at 5.5Hz for me). But it seemed to work in...

There is a hdtv-test video where he shows that if you spam the green button you get a link/resolution/refresh/vrr status window. Mine on .26 firmware always shows 5.5Hz as max, where with vrr on it can variably drop. 5.5Hz in 120Hz content. His video however, seems to show the proper refreshrate...

Can you even downgrade from .26 to .25? i put .25 on a usb to try and it just says no updates.

Hmmm... the one i have is 03.11.26 actually.

On hdmi 2.0 you only get 60Hz 8bit rgb. for 10bit you need to drop down in refresh, but you can do it if you want to watch video content for example. 10.25 and 10.26 have been out, but judging by previous replies in the thread possibly been recalled (likely since they don't work properly).

I think this is a glitch with the "instant game response" mode not triggering properly sometimes, turning it off/on again fixes these issues for me, i need to do it sometimes when turning the tv on, but not always. Definitely perfectly smooth in the 100-120 fps range. Turning off instant game...

The extra bandwidth would be pointless for picture quality, but 144Hz would be neat. I feel that these oled's now are as near perfect as display tech has ever been, and if i upgrade in the future it will be for higher refreshrate.

I have the same issue maybe 1/5 times i turn on the tv. It is solved for me by disabling then re-enabling instant game response. For it to work at all, you need 03.11.25 or 03.11.26.

While everything seems to work perfectly now (03.11.26), sometimes when i turn the tv on i have to disable/reenable instant game response, else black flickering. Anyone else got the same?

03.11.25 pushed to EU now. (still getting random black flashes, though rarely, and still looks like 4:2:2 with asus tuf oc 3080). [edit: just in case, i tried changing from hdmi4 to hdmi1 on cx, noticed pc icon had reset, fixed it, everything works, 4k, 120 g-sync, 4:4:4 - no idea if hdmi4 has...

Got my 3080 yesterday, and can only conclude what is already known; 4:2:2 displayed even though the gpu can send 4k/120/rgb/10bit signal. Works well enough for now with instant game response off and vsync i guess - still beats the previous 4:2:0.

Possible, but that makes no technical sense? It still needs to have bandwidth to accept and process the signal and then it's just more work to downsample than to just display it fully. The CX is clearly capable of displaying a full RGB signal at 60Hz, so it should just be a matter of bandwidth...

It can. (From SweClockers forum), but reportedly vrr has issues.

New firmware today, 03.10.44, no idea what it does/can't find patch notes.

The colors shouldn't be washed out. I think it's some sort of semi-rare windows configuration error or bug. Back when PG27UQ was new and people were discussing early windows/game HDR, some people complained about washed out colors in hdr, but it never happened to me (nor most people). About one...

When you enable windows hdr, you also get a slider for sdr content brightness, just adjust that. has worked generally fine for over two years.

How many dimming zones does it have? the g9 only has 10.

Are you sure you turned cleartype off? in windows you need to uncheck the box and still go trough all next-next-next-finish steps to turn it off. The text on this site, or in notepad should look perfectly normal, for example, since it is white on gray/black on white. The headers saying "today...

Probably something wrong, 4k 120Hz 4:2:0 looks perfectly fine for me for moving rendered graphics, except for the mentioned fringing (on colored text, black/white text looks normal with cleartype off). Cleartype simply can not work with reduced color resolution, since it tries to use rgb...

Turn off cleartype when using 4:2:0, apart from that, you can use larger scaling - 4:2:0 only looks really really bad on pixel-thin details.

Doesn't work on my 55CX, it actually accepts it but colors are all messed up and not fullscreen.
