Do you know a way to adjust monitor RGB ?

That's why I don't like AMD. Yes, there is a way to configure the monitor (resolution and color), but it is not obvious where to look and as I don't have an AMD, I cannot guide you how to find it. While in nVidia control Panel all settings are straightforward, you don't have to guess where they might be! I think your next graphics card should be an nVidia

PS: I haven't checked with recent AMD cards, but in the past using an nVidia you had almost perfect image and colors, no tweaking required, while using an ATI/AMD card would have poor quality, even in native resolution, and needed some tweaking to get an acceptable image. Even after tweaking it was nowhere near the nVidia quality. Text wasn't very clear without using ClearType configuration to make it better.

PS2: From Google AI:
To configure colors in AMD Adrenalin, right-click your desktop, select "AMD Software: Adrenalin Edition," then go to the Display tab. You can either enable Custom Color to manually adjust saturation, contrast, and color temperature, or use Display Color Enhancement for pre-set options like "Vivid Gaming" or "Dynamic Contrast". For game-specific settings, navigate to the Gaming tab, select the desired game profile, and enable Custom Color there to apply settings only to that game.

Needless to say that before changing any colors from software, make sure you have neutral colors from your monitor controls. You can set 6500K color temperature, but I find it a little yellowish and I don't like it. I prefer to manually set all R, G, B values to 80% or 100%, so I get a neutral image, not too cool, not too warm. I then adjust the colors from Windows, and I fine-tune them from my nVidia Control Panel. For example, I have to set "digital vibrance" to 36 (default is 50) because I get too much vivid colors on my Sony TV monitor.

ColorControl v10.4 is out, it works also on AMD Radeon:
I suspect that it has something to do with the wrong color space being used.

EDIT: Here's confirmation from someone who was apparently also having the same problem of getting exaggerated redtones:

@hdmi ColorControl did not actually work. it is like color management.

Load AMD Control Panel and look carefully all the tabs. Somewhere you can select the display colors, however it's not as easy to find as in nVidia Control Panel. What was AMD thinking when they made their Control Panel?

I'm unsure, but I believe nowhere.

Custom color? That should be.

Nowhere. Maybe it was in the old ATI drivers

I was referring to the screenshot on post #25, it looks to me like modern AMD Control Panel. See the Display section, custom color. I guess you must first change the color temperature from 6500K to "custom" or "user" so it gives you access to the individual color values. Like I said AMD Control Panel is counterintuitive...

PS: Having a second look at the screenshot I spotted "Desktop color" top right. I am replying from my smartphone and I don't see all the screenshot unless I zoom and "pan-and-scan".

@spapakons no way to adjust RGB values

What can you do in "Desktop Color" section? It might help you get rid of the red hue and get a little more natural colors.

Create a color profile. exactly like calibrate display color

If AMD Control Panel has no means to tweak the desktop color, then it is yet another reason to stay clear from AMD products and stick with nVidia which also has greater performance than equivalent AMD ones.

I wonder if "William654" would be happy just to raise the color temperature a bit? (Post 25.) That'd tend to take things away from the red.

In that case, I would gradually raise it to 8000K+ and then to 9000K+.

Multiple users have reported online that disabling that option for HDR makes HDR look a million times better, though...

First, I would make sure that the pixel format is set to "RGB 4:4:4 Pixel Format PC Standard (Full RGB)".

This is applicable for 1080p. I might be wrong, but I think for 4K resolution the color format is automatically changed to YCbCr limited range.

Did not work with me but thanks for all the help.

Have you tried both Desktop Color and Game Color options top right? One of them should let you change individual R,G,B values, otherwise AMD proves one more time is no match for nVidia.
