Samsung UE50NU7472 Color Problem in Games

Good day to all!

Recently bought a new RTX 3070.
Was trying to play some old games with DSR from Nvidia above the native resolution of my TV(3840x2160) like 4096x2160 or even 8k.

But immediately after I change resolution above native the colors change and look somewhat bad, like a red and/or yellowish filter was applied. This happens both at mere 4096x2160 or very high resolutions like 8k.

My PC is as follows:
Ryzen 5900x + 32GB DDR4 + RTX 3070 + 1TB NVME SSD + Windows 11x64 PRO.
The TV is a Samsung UE50NU7472 with 3 HDMI 2.0 connections.

Nvidia Control Panel Settings:

Manage 3d Settings:
Sharpen on
DSR Factors cu Smothness 0%.
Power Management Prefer Maximum Performance

Ajust color enhancements:
Digital Vibrace: + 70%

Use Nvidia color settings:
Output color format: RGB
Output dynamic range: Full
Scaling: No Scaling

TV settings:
Backlight 50 max
Contrast 50 max
Brightness default
Sharpness 10 default
HDMI Black Level Low
HDMI UHD Color activated on HDMI 3(arc) which is connected to RTX 3070 with a high speed HDMI cable

I made comparative pics with phone. If I make print screen pics they look normal but taken with phone show the problem.

Q:What is the issue?

This happens in all games.
Also the color issue, it happens on desktop if I change it to 4096x2160 or above. So not only in games.

Do you know if your TV actually supports the resolutions you're feeding it ? I'd be surprised if a 4K TV supported higher resolutions than 4K but, then again, I'd expect you to get no picture rather than a picture with dodgy colours if that was the case, so I might be wrong.

TV spec tables used to contain lists of supported resolutions but I've just checked mine (to get an idea) and can't see that information. You might want to check your TV's specs or manual ?

Assuming he's doing it right then he's feeding it 3840x2160. The resolutions he's talking about are the DSR settings. It's essentially a alternative implementation of of Supersampling AA but the supersampled resolution is often chosen to specify it's strength rather than the traditional multipliers.

Are you running in HDR mode or not?

Digital Vibrance stands out in your list. If it's incompatible with DSR then it's possible it's being disabled when DSR is activated which would result in a colour shift.

I'd also be tempted to try disabling the deep colour support on your TV.

TV has HDMI 2.0 which supports 4k 60FPS or up to 8k 30FPS.

HDR in Windows is off.
I disabled HDMI UHD Color. Digital Vibrance default. DSR off.
The same thing happens when I increase resolution to 4096x2160. Shift in colors. A annoying filter on the image. The colors look like very oversaturated.
I can still chose 4096x2160 with DSR off.
Looks really bad.


The same thing happens on the desktop if I change above native resolution.
