Anyway I am sure I'm just looking in the wrong place, but I'm still confused about what some of the HDMI 2.x Support settings do.

I am using an LG C1 OLED as a display with nvidia 3080 gpu. I attached my current settings. I have Max FRL at 48 Gbps and TMDS rate set to 660 and I know what these do. I have deep color up to 48-bit enabled and understand these. I know what DSC is but don't use it.

Most of the other ones I'm clueless: Fast Vactive and ALLM and FAPA start are enabled but I'm unsure if they should be. M delta, Cinema VRR, and Negative M VRR are all disabled. I'm curious in particular what these last three do and if they might be useful for me?

I don't have the HDMI 2.1 specification, and there isn't much info about this online, so I'm not sure what everything means.

Fast Vactive means the TV is capable of using a higher pixel frequency to complete the refresh scanout faster. I don't think this applies to VRR because VRR already does this inherently.

Auto Low-Latency Mode means the TV is capable of automatically switching to a low-latency mode when requested. I don't know if Windows drivers use this feature. This is probably something game consoles use.

FAPA start location has something to do with the frame accurate packet area.

Cinema VRR means the TV is capable of handling film refresh rates outside of the VRR range.

M delta and Negative M VRR have something to do with VRR calculations.

10 years now I've been talking to you ToastyX How are you!
Auto Low latency mode and fast Vactive - Are they only for TVS? Or any monitor that benefits from HDMI 2.1 such as the LGOLED 27 with a 4090?

Any HDMI 2.1 display could implement those features. ALLM has no purpose if the monitor already doesn't have lag, and fast Vactive has no purpose with VRR because VRR already scans at the fastest rate.

Monitors with the G-SYNC processor normally don't support custom resolutions, so you'll have to use GPU scaling. It'd be easier to create GPU-scaled resolutions using SRE: https://www.monitortests.com/forum/Threa...Editor-SRE

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)

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 @ToastyX

I tried to follow these instructions with my LG OLED to enable dolby atmos/surround on my PC https://www.gamerevolution.com/guides/66...-with-earc

Although after doing these things, my tv refuses to display anything from the PC

I tried to go into safe mode and running reset-all.exe

Would appreciate your help here. Thanks!

Hello, I have a problem. I recently (about half an hour ago lol) installed Windows 11 and can't set the appropriate resolution. The thing is, I'm using an old CRT 1680x1050 60Hz monitor connected to a GTX 1650 via a VGA to HDMI adapter, so when I first install Windows, the system thinks my native resolution is 800x600, and after installing the drivers - 1024x768. On Windows 10 I just added my native resolution to the CRU and everything worked just fine, but Windows 11 just ignores any changes to the CRU as well as the SRE. The only thing that works (kinda) is the NVIDIA control panel, but the colors start to get distorted. For example, some color wheel looks fine, but the gray to white gradient looks like a bunch of big gray bars. And by the way, it shows me that i'm using "DVI-PC Display". What can I do to make everything work the same as in Windows 10? Once again: CRU doesn't work, and neither does SRE.

Does CRU works on the new RX7600? Or has AMD completed fused-off third-party EDID access with RDNA3?

Can anyone confirm it?

Thanks!

i wanna create custom resolution 1920x800 but my computer or my screen doesnt respond this settings im trying i don't get any error and no feedback all ways and methods and still doesn't work can aynone help me please.

EDID has been broken for all AMD cards since the 22.12.1 driver that was released alongside the 7900 cards. Use the bug reporter tool to report EDID overrides not working and hopefully it'll get fixed at some point. I've been filing bugs for every release.

What does CRU show? If you see "Generic Non-PnP Monitor" with no resolutions defined, then the monitor doesn't have a valid EDID. Windows 11 doesn't seem to support EDID overrides for monitors without a valid EDID for some reason. You would need an HDMI to VGA adapter that provides its own EDID, or you can add an HDMI EDID emulator like this one: https://www.amazon.com/dp/B08RCMFLMK/?tag=mtests-20#ad
