Asus XG27AQDMG Discussion

High Hz on OLED produce excellent strobeless motion blur reduction with fast GtG pixel response. It is easier to tell apart 60Hz vs 120Hz vs 240Hz on OLED than LCD, and more visible to mainstream. Includes WOLED and QD-OLED displays.

Hi and thank you very much for the response. Regarding VRR, do you enable it? I am currently using it with G-Sync + V-Sync enabled on NVControl, refresh rate 240, ultra-low latency mode, and I must say that from what I have seen, I haven't noticed any tearing. Anti-flicker disabled? Then, forgive me, but I have one last question: when I try to use novideo_srgb as you indicated in the first post and check the "clamped" option, the screen seems to have a light film (I don't know if I made myself clear). I should mention that I hadn't loaded any sRGB profile in the Windows environment
I use VRR for some games. I disable it in some others. It depends on whether the game has VRR flicker or not.

I don't see any "film" with novideo_srgb.
I think he means the colours looking more washed out when you enable the clamp, which I also experience.

It does kinda look like a translucent white filter is added, using either the ICC profile from Rtings/Asus, same thing happens. But it also makes white skin not look sunburnt which is nice.

But when I enable EDID primaries + Clamp instead of a colour profile, it seems to remove the over-saturated look from skin etc, and also doesn't add this white "filter", or whatever it is that's happening with the colour profile + clamp. Do you also experience this? The only colour profile in my Windows settings is one for HDR, SDR is empty so it's not a double clamp

It should look about the same as when using the monitor's built-in sRGB clamp (Color->Display Color Space->sRGB) with the only difference being that there's less black crush.

sRGB gamma using an ICC profile in novideo_srgb will result in the image becoming washed out, that is true.I now removed the suggestion to calibrate to sRGB gamma. If you want sRGB gamma (which raises blacks) you can switch Windows to HDR mode instead, which does the same thing. (Windows uses sRGB gamma instead of 2.2 for displaying SDR content in HDR mode.)

What do you think is most accurate for SDR? Idk anything really about colour accuracy and stuff, but EDID primaries + clamp seems the best to me. I can see up to Square 3 on black level test with this on 100% brightness, square 4 on 50%.

And about VRR, if I play Elden Ring with VRR on it limits refresh rate to 60hz(with HDR on). Does this mean the gamma is not correct bc it's at 60hz? And if so would I have to raise or lower the gamma when the refresh rate lowers to such a degree?

Sorry if you have already answered this, it's my first OLED and I want it to be a good experience

I also use that. Plus 6-bit temporal dither in both SDR and HDR.

You can't fix gamma at lower refresh rates through the monitor itself. You can use reshade and a shader for fixing the black floor if you want.

Me, I just use LSFG with 60FPS locked games to get 120FPS.

is gamma lowering due to VRR also lowering a common issue in OLEDs? or this monitor specifically?

To be honest I don't even notice any difference in HDR at least, fluctuating VRR doesn't seem to make the screen darker or anything

It's a common issue in many OLED screens, but not all. There's laptop OLED screens for example without this issue. Also, there's an OLED monitor with a g-sync module (the only OLED that has one) and it also doesn't have this issue.

It's something that's only noticeable in dark scenes with lots of shadows. You can use a keyboard binding to toggle the RTSS limiter on/off for example to switch between 60FPS and 240FPS with g-sync enabled and see shadows become brighter/darker.

I'm a new owner and so far it's been enjoyable. I got a reasonably clean panel which was a bonus, I went through hell a few years ago trying to get a clean OLED TV.

Anyway, my issue is that I'm struggling to get a stable frametime in Cyberpunk. I'm running at 120hz and limiting the fps to 75 and the game really doesn't like this. It works beautifully in other games like Doom Eternal and Morrowind but Cyberpunk stutters (and flickers) terribly unless I raise the fps cap closer to max refresh.

I can see that the fps is fluctuating up to 120 so I guess that CRU is kicking in.

Locking FPS closer to max refresh is far smoother but still not perfect.

If I disable all fps caps and even vsync the game runs astonishingly smooth for a while but eventually has a bout of extreme stuttering that can only be fixed by enabling and disabling vsync in the menu.

Anyone have any idea what's going on?

*Edit*

I forgot to mention that this is only affecting DLDSR resolutions. Native 1440p seems ok.

Also I can't use 75hz mode at all in either native or DLDSR. It's a stutterfest.

On my previous monitor I set refresh 75hz and capped at 70. It was perfectly fine. The only change I have made is the new monitor.

*Double Edit*

I figured it out. It turns out Cyberpunk has a quirk where the desktop resolution has to match the DLDSR resolution or else it stutters. I totally forgot!

I've not played this game in a while because I wanted to christen an OLED monitor with it. Tonight's the night.

Does the 6bit dithering fix affect the colors is any negative way?

I can't see a difference in the colors.

I just bought the monitor, and the novideo_sRGB 6-bit solution really helped with the color banding issue that was driving me up the wall. I really appreciate it!

Quick question: this is my first OLED, and I chose it because of the great value and the high ratings it received (on RTINGS and HUB). However, does having to lower the bit depth to fix this issue suggest that the monitor is more limited than it seems? Should I consider getting a better model instead? I was torn between the MSI MAG 271QPX QD-OLED E2 and this one, and eventually went with this one, but after struggling with color banding, HDR not being as impressive as expected, and some slight VRR flicker, I’m starting to have second thoughts.

I’m actually considering switching back to an IPS monitor.
