Unchecking the Enable settings for the selected display model checkbox fixes this. You can test for stuttering by looking at the Hz value in the FreeSync Information screen on the CX when running at a constant framerate capped below 120 fps. If the Hz value changes while the frame rate is constant, G-SYNC is stuttering.
It works fine. That's what I use globally on the desktop and in all games. The G-SYNC stuttering fix is posted above.
I had to settle for greyscale, because Cleartype just added too much fringe to the edges that really stood out at times. Some apps/colors/fonts are fine, but you'll occasionally get a combo that Cleartype butchers
So with the workaround all of these together work properly at the same time: HDR, GSYNC, 4:4:4, 10-Bit, 120hz? So no more compromises with this screen and latest firmware? Just trying to be clear.
having spent some time tuning cleartype on this screen - I think you have your contrast too high if you can see that green edge. I know when a white edge splits a pixel you get full red + full green + no blue and it looks just like that even on an LCD. I repro'd it on my screen and took this picture - the green edge is clearly visible in the photo but I cannot see it unless I place my nose about 6" from the screen - and from that close it looks no different than an LCD:
Well, if he's disabling display specific VRR settings for the display it could fix the stuttering but yeah, you'd think it would disable VRR for that display which means tearing or reverting to regular v-sync (or fast sync) if either of those was still enabled.
Powercycle the TV and disabling G-Sync, apply, reenable G-Sync.
Well then the obvious solution is to turn off cleartype altogether.
I'm using 10-bit RGB. Are you sure G-SYNC is active in-game? The CX says VRR even when G-SYNC is not working in-game. Does the G-SYNC Compatible Indicator show up if you enable it? I sometimes have to disable and enable G-SYNC for it to start working.
Comparing the OLED with different subpixel antialiasing setups. RGB and BGR have clear fringing that I don't spot on LCDs so the subpixel structure of the CX 48 is not ideal for these. Grayscale works fine to my eyes but took me a bit to get used to it as Windows does a bit of fuckery with it for some fonts on legacy apps.
Unchecking that box just disables Freesync afaik.
I also see the 5.5Hz bug on the VRR hidden osd, spontaniously jumping up and down when I get into the mentioned situations on my 2070S..
In my case, unchecking that box makes the Hz value stable with G-SYNC at any locked frame rate below 120 Hz, and the stuttering stops.
Do you constantly hit that locked framerate? Because then it's not G-Sync working, but just no stuttering/tearing due to a stable framerate..
Some people have it working with certain settings combos, as well as with certain games. If it was straight up broken and never seen working, I'd be hesitant. But we know it's possible and we know it's close. I'm not worried
That's what worries me. If it was straight up broken LG/nvidia/MS would have to react.
This seems correct.
With what card?
3080. Inno3d x3
"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. "
I'm just glad they think they can fix it. If they can make 4k120 4:4:4 10-bit HDR and GSYNC all work at the same time without stutter, it will restore my confidence in them for future TVs.
8-bit didn't make any difference. G-SYNC still stutters unless I uncheck Display Specific settings. It runs the same as 10-bit.
This might kick a hornets nest but... can someone explain the downside of 8bit 4:4:4? Is it just some banding and limited HDR? Or is HDR completely disabled
You can definitely still run HDR, because you've been able to do 4k 60hz RGB 8bit HDR Gsync on Turing since the TV came out.
As far as I know, yes. I haven't seen anything else on this TV that's a deal breaker (is the raised-blacks for VRR still a thing?)
Yes it did because I can switch back to 10bit with that check box off and it's a mess. I tried the check box thing and enabling VRR via Windows 10 over a week ago with no success.
I get extreme stuttering at 8-bit with Display Specific settings checked. Just need to wait for a fix. With the box unchecked, i need to toggle G-SYNC off & on each time my display switches off.
Linus finally made a video about our screen
And I get no Gsync if I uncheck it regardless if the display switches on/off
Yeah this is why LCD screens above 120hz are dumb. They can't actually transition that fast, it's all just marketing bullshit that leads to a blurry mess of overshoot.
