Yes, I only use SDR if I'm browsing the internet and HDR on all games like you. Did you have the same black crush when you first used the monitor with novideo? Like without editing CRU or NVCP or anything

It was long ago, I don't remember, but I couldn't fix it with primaries, that's all I can tell. So I googled even further and tried icc method. Still looks ok for me no matter how I look, I can't complain, we should be lucky to have such a solution, amd gang took the l again lol.

The only difference seems to be you changed more things in CRU, but if it wasn't colour related idk. Anyway, I don't think your monitor is cursed lol. I bet if you formatted Windows and started completely new, reset all your monitor settings then it would probably be fine. Only seeing square 7 or 10 first seems like it's too much of a difference in just how the panels are built and I guess is more likely to be a settings issue. But I just got this monitor a month ago so I'm clueless about this stuff

You never know unless you try, but I don't plan on reinstalling os in the near future. Well maybe when ms finally fixes their 24h2 builds, then I can do a clean reinstall. Too much hassle to do it anyway. 23h2 still is the safest choice now. And old nv drivers, post-50xx ones are a mess. Currently I'm on 561.09, works in all games, maybe when new ones start complaining about it, I'll consider updating to 566, a bit newer working driver branch.

I know that's a bit late, since it's a thing for several months already, but for someone who will be reading or searching for this.
Despite looking much better than PG27, hdr in this model can still look odd with yellow colors, when there's a lot of yellow lighting or dim desert-like sunlight. Not that bad, of course, but if the surface is also yellow or skin-colored, it will produce a mustard film, almost as if there's too much color on the surface.
That's where adjustable hdr comes to the rescue, that was introduced in 104 firmware. Those who used the previous PG27 model (they have the same panel) are well aware of this and that it can be mitigated by setting 8200k color temp. Now we can set it too, it has the same effect, mustard spots are almost gone. But you can also set your own rgb values. I don't know how color temp is set internally, but from what I can tell, if I set my preferred sdr values, it fixes the lighting, but the picture becomes a bit less bright, naturally. Setting them to 80-90 values almost matches 6500k mode, but it still helps and looks bright enough.
Considered mentioning all this when I remembered that I was initially giving suggestions on how fix yellow colors in sdr to _zebracrossing666, then I launched FF VII Remake in hdr and booted into chapter 3, where there's a lot of yellow sunlight and remembered that now I actually can try different color temps and here we are.

Are you using 90 or 100 brightness in HDR? I found that 100 brightness loses a lot of shadow detail and blows out basically every colour, I get that it warns you the PQ curve is affected when you switch to 100, but it really looks bad to the point I don't like using it.

What colour temp do you have on HDR? I have mine set to 6500K and it looks way more yellow than what I expect 6500K to look like. 6500K is supposed to be on the cooler side yet I see warm/orange being the more pronounced temp

Yeah, I've noticed this too, also seen this before, it was mentioned in one of the reviews at least. It happens even after asus supposedly fixed it in 104. Moreover, some people report that the screen has better peak brightness with 90, than 100.
So I use 90.

I was experimenting with my current sdr values and upped them to 85-80-87, so +10 flat for every value, because the original were noticably dimmer. Looks way better than before, despite being a tad dimmer than 6500k preset. As they say if it works, do not fix it, so I'm not going to tweak further, that'll become a neverending search for the ideal picture and I'll spend more time tweaking than actually enjoying games. That thing better left for those who at least own a colorimeter and know what they're doing.
Also 8200k looks not so bad, if you prefer a colder look. It depends on a scene, if it's bright upping color temp will make a little change, if any, and vice versa, if it's dark, colder temp will brighten the scene. In some cases even 7500k is enough to fix orange issues.
That's just me tweaking and comparing stuff in one game for no longer than an hour, but I guess it's more or less universal across the board.

I made a video showing the screen tearing with no VRR no sync at all on Cyberpunk, apologies for the quality, I'm using a low-end phone from 2019. However the screen tearing is visible on the bottom half of the vertical bar of light in the video, at least I can see it, it's like small parts of the light bar are being sliced. Not the usual screen tearing where a giant horizontal line is visible across the screen. After 0:13 is a different video showing the light-bar with broken VRR + Vsync + Low latency mode. Again, probably can't see well, but there is no screen tearing at all with this. I guess it COULD just be Vsync + Low latency mode doing stuff, but I read online that Vsync by itself adds noticeable latency, I presume even with Low latency mode. Yet it actually feels smoother for me

If you're happy with the result, then of course use it. I'm just saying that I can see the (minor) stutter with the CRU tweak. It looks the same as VRR off to me.

What settings do you use if you still use this monitor btw? I mean strictly in terms of using VRR or not, or any sync.

For games that don't stutter much and thus have very little VRR flicker, I use g-sync at 144Hz with a 90FPS cap (I don't need more than that.) 144Hz results in less visible VRR flicker because the display doesn't jump all the way to 240 during frametime spikes.

For games that do stutter more and thus have too much VRR flicker, I use 180Hz (with g-sync disabled in NVCP) and cap to 1/2 refresh rate (90FPS) with SpecialK. Input lag is very low that way, because capping FPS below the refresh rate eliminates vsync lag. There is no stutter because SpecialK can cap the framerate perfectly to exactly half:

240Hz with a 1/2 cap to 120FPS is an option as well.

No frame skipping.

You might see bright squares (frame duplicating).

Yep. Just like with the mouse cursor test, some squares are bright:

Hey, I just did this frame test while VRR is enabled and with the custom VT lines method.

Here is the pic

To me it doesn't look like I have frame skipping or duplication, but do you agree or am I missing something? Also you have it set to 180hz, is this because you set the refresh rate to 180hz in Windows and just used default VT lines that comes with VRR at this refresh rate?

One thing I have noticed, and idk if it's me paying too much attention at any weaknesses of this method, but moving the camera around in a game may look slightly more juddery than default VRR settings, even though the frame test here looks okay

Here is the pic

I said that the 180Hz mode is broken and that every other mode is not affected.

Hello everyone, i wanted to disable Text Clarity as some people suggested here, but i don't seem to have that in my settings

Do you guys know why?

Yes but you also said editing the VT lines just produces the same results as switching to 180hz ie VRR isn't actually working even though it looks like it's working in the OSD and mouse movement, and that this causes frame duplication. I have changed the VT lines on 240hz to the point VRR flicker is gone, but I have no frame skipping or duplication(I think, only found out about this test)
