The UI on external Monitor turned into red

Hi,

I have a problem with an external monitor. I recently added a post about my laptop display was displaying everything in yellow (link to the topic: The UI turned into yellow)

The solution was to switch in the BIOS from discrete graphics to switchable graphics.
The problem now is that when I connect an external monitor, the whole UI turns red, as before yellow.

I don't really know how to explain how it looks like, so I will leave a link here to a image hosting site with a photo of my problem: 5c7e34bc-eb37-4405-9621-a7ccd0b4aadd — ImgBB

I just want to add that it is not the hardware fault, because it was already tested on other devices.

Can you help me please?

Has it been red the whole time? I see the "solution" for the yellow color is from nearly six months ago.

I have never connected an external monitor before, I only found out about this problem today.

Can you examine the monitor and try to determine what the model number is?

It's Philips 241v8la/00, but as I said, I don't think it's hardware fault, I have Windows 10 on other partition and it works well.

There should be a color menu accessible on your monitor where you can manipulate the color bias you are seeing and try to achieve a more reasonable balance.

That may be true, but keep in mind the manufacturer made a special driver for this device that is only available for Windows.

Even if you did not intentionally download this driver, it is very likely your machine was able to download it (or a version of it) without your knowledge or with an unobtrusive notification while you were setting up the monitor.

It is impossible to say exactly what that driver does, but it is certainly possible that it automatically adjusts the color of your monitor for you, or other things that you will have to do manually without the special driver.

Some models have this kind of graphics auto switching, but it (the automation) is designed for WinOS and it seems to communicate with WinOS video driver.
As some times reported, BIOS firmware shows/hides one video card during activity changes, with unknown (and uncontrolled from Linux) logic.
If there is an option for Always All Cards On, or similar, Linux should be able to control them both. Nvidia proprietary driver for Linux has released some kind of automation per workload (a kind of auto-switch). Maybe this could help you with your issue, or not. (You are now using Open Source nouveau) :person_shrugging:

In the meantime, you could test if opening some program like Firefox (demanding app) with prime do produce something different.

DRI_PRIME=1 firefox

what is the connection ? hdmi, usb-c etc. going via a dock etc
