It's like when game mode is on, it only accepts a signal that's outputting VRR. But when it was off, it just stays in a non VRR mode.
I understand what's happening now. The TV is changing the EDID to include VRR when enabling game mode, but since the device ID stays the same, the EDID override affects both modes, so VRR stays active when disabling game mode, but the TV doesn't support VRR with game mode disabled, which is why you get no signal. I'm not sure how to work around this because there's no way to do a separate EDID override for each mode if NVIDIA's driver considers both modes to be the same display. The easiest option would be to just use game mode all the time. The more advanced option would be to modify the EDID on the TV directly, but usually it's write-protected, and I'm not sure if the service menu offers a way to unlock it, and every firmware update might reset the EDID.

Yea that makes sense, and touches on what I thought might resolve it: having two EDID profiles so the TV can operate in both modes

What monitor do you have? What is the "other tweaking" you did with NVIDIA?

i have the LG 32GN650-B and as for nvidia it was adding a custom res to the dsr list but from what i under stand it cant be done with amd since vsr is driver based and dsr is software based. i tried the vsr tool that you have but it will not show because of what i assume is the aspect ratio that 7680x1440 is 48:9.

Are you using three of these LG monitors? Why not use Eyefinity to combine them?

yes i am its just that eyefinity always end up breaking something or just not work but i guess ill just have to live with that. Sad

maybe one day ill figure it out.

Thinking about this some more, could I export the two EDID versions with CRU as .exe files and that would let me switch between a game mode and non-game mode EDID?

Is there a workaround for this at all? I'm using an RTX5080.

Same TV and same problem, sort of.

Turns out, it is all about VRR.

Disabling VRR allows to freely edit EDID, TV will respond to changes.
Disabling High Refresh Rate in HDMI settings also allows to edit without TV going out of signal, but then Nvidia driver/Nvidia Control Panel freaks out.

this is what i mean. can you look at it?
That's something your monitor is doing. GPU scaling should work around the problem by scaling to the native resolution. For GPU scaling to work, you need to make sure the same refresh rate exists at the native resolution.

my monitor is a samsung odyssey g4 (240hz @1920x1080) so i think that one is the native resolution, and it supports 240hz (i've been using it since i bought it)

but i want to force 1350x1080 @240hz and that behaviour appears.
i dont know what im doing wrong,

i tried gpu scaling ON with three diff options (keep aspect ratio, fulls creen and centered) all of them behave like the image i uploaded there ONLY when i go up from 190hz in the resolution i want to use (1350x1080)..

any hint? (thanks in advance and sorry for my complete ignorance about this subject)

////////////////////////////////EDIT////////////////////////////////////

I GUESS I MADE IT WORK, i had to add that resolution to a detailed resolution extension block AFTER creating it with the SRE.exe Hahaha

hi i have the same monitor and same proplem what is sre.exe can you dm me on instagram [haiitmq] plz

Hi Toasty! Having some issues with getting 4K 120Hz 8bit 4:2:0 on Windows 11. Plugged into a Sony A95K 65". GPU is a AMD 680M (iGPU) and only has an HDMI 2.0b port, plugged into a HDMI 2.1 port on the TV with a HDMI 2.1 cable (confirmed working). I know this setup it works as I can get the above resolution on Linux (Wayland).

I've tried using CRU to adjust the CTA-861 extension block > TV Resolutions. It already has 3840 x 2160 @ 120Hz set.
I tried ticking the 4:2:0 check-box in the top corner. I tried removing all other resolutions except the one I want.
I tried removing every other resolution everywhere else in CRU.

hen trying to add a full custom resolution in the AMD driver, it always throws a "This custom resolution is not supported or invalid". I tried every custom timing from resolution / timing calculators online. I have tried clean installs of Windows 11 home, but usually I run LTSC with both the manufacturer provided GPU / Chipset driver (since it's a laptop) and with the latest from AMD.

Unfortunately Windows will not let me set 3840 x 2160 @ 120Hz no matter what I do. With the stock profiles, whenever setting 120Hz, it will revert to 1080p. After adjustments with CRU, It only shows a maximum of 60Hz @ 4K, even at 4:2:0.

Would you by any chance know a way to get around this? Thank you!

You would have to ask AMD support why their driver allows it with Linux but not with Windows. Technically HDMI 2.0 only specifies supporting YCbCr 4:2:0 with 3840/4096x2160 @ 50/60 Hz, so maybe that's why, but the hardware should be able to do it with 120 Hz anyway. It's likely the TV already defines 3840x2160 @ 120 Hz as supporting YCbCr 4:2:0 through the YCbCr 4:2:0 capability map data block, so you shouldn't have to do anything. I can check if you run this and post the edid-test.txt here: https://www.monitortests.com/edid-test.zip

If you're using CRU, you should keep the resolution to a multiple of 8 or 16 because the monitor can't correctly split other resolutions internally, or you can use GPU scaling which shouldn't have that limitation. SRE is Scaled Resolution Editor.
