I created color profiles in windows with Spyder X Elite for my both Displays. Now i added both profiles to my displays on zorin. On my main display (4K) connected with Display Port all is fine. But my second display (1080p) connected with HDMI looks like too much contrast. This was without adding color profile too.
Why this happens? In Windows contrast looks normal.
I have experienced minor differences in display when using one monitor connected via display port and another connected via HDMI. It can help to have matching connections.
Same as me... and I also happen to be using one display port and one HDMI connection since the Nvidia card only comes with one HDMI port and three DP ports.
But I have not experienced this contrast difference.
Could it be because of the 4k TV being used? Have you checked the onboard settings of the 4k screen? Are you using fractional scaling?
The high contrast is not an issue on the 4K Display Port Screen. It is an issue on the 1080p HDMI Screen. When i boot into my Windows 11 the issue is not present. So its not a display onboard setting. I dont want to change the display onboard settings cause i dont want to mess up my calibrated monitor settings in windows 11.
For testing purposes, can you open Software & Updates and in the Additional Drivers tab, switch to the Nouveau open source Nvidia driver (You must reboot after the switch). Then test if the contrast is still present. This step is not intended as a solution, but a test.
Now it has completely destroyed my Zorin. After I installed the Nouveau open source X11 driver, I could only get into the system via Wayland. However, this did not solve the problem with the poor picture. Then I installed the 535 open nvidia driver (stable, tested) and now I can't even get into the login screen. I just get a black screen with a blinking cursor in the top left corner. Nothing can be entered.
I could now boot into zorin again because the nvidia drivers were deleted. I have now reinstalled the nvidia proprietary driver (not the open one) and now everything works again. In any case, the display problem of my second screen has not been fixed.
No there was used the open source driver by deafult after removing the nvidia software components. from my mainboard there is no cable going out. Only 2 cables directly out of my graphic card
Let me research this a bit. I do not believe we can do much with the Nvidia driver. The test of Nouveau was to determine how flexible the card is. Apparently, not at all. My own 3060 is also finicky, so I understand the feeling.
I doubt this is a hardware issue since the issue is not present on Windows OS. But it may be that the drivers supplied to Windows are more complete. What Nvidia is willing to supply to Linux can be meager...
