Monitor yellowish shortly after start-up?

I have a rather annoying problem at the time of my home office:

When I start my PC, my monitor is still beautiful white in terms of colors! But after about 10 seconds it starts to turn yellow (in several short steps - takes about 2-3 seconds). Then it is also quite dark and so orange!

Since the monitor is white at the beginning, I think the problem is with the PC!

The colors of the PS4 also look great!

PC: Lenovo MQ920

Monitor: Benq RL2755hm

(Yes, night mode is disabled!)

If the monitor works otherwise, I tap the graphics card that gives up the ghost.

Check all cables. Try another monitor to see if it is on the laptop output?!

Can you check them?

The PC would only be one year old.

I have already exchanged the HDMI cables - without success.

Unfortunately I have no monitor available. But as I said - the monitor works with the PS4

The problem is probably with the graphics card. Actually you can't do anything big anymore, it will eventually no longer display a picture and then you would have to get a new or at least a used one, or if there's still a guarantee on it, contact the respective manufacturer ^ - ^

I also have a Lenovo s c h e i… In the company, it works flawlessly on various projectors in the meeting rooms. In some the picture flickers or goes away for a second.

Yes, by exchanging what is not possible with your think center.

Try another output. There should still be the VGA and a DP output. Possibly. Is only the HDMI port grizzly

Would be extremely stupid if it didn't work anymore

Doesn't have to happen right away, but it could happen. Depending on usage
