Display problems

[mordox]

So last night i was watching a serie on my Q10 pro and everything was great. This morning i woke up and i boot my media box, after it booted the screen looks a bit shit like i am watching a old tv.  The screen seems blurry and i don't know how to fix it.

I did check the setting of de Q10 pro and the display settings go to max 1080p 60hz (while i got a 4k TV). If i am correct i could find the  4k settings in here before but i cant enable them now. So i did  check if there was a update avaible, but i am already on the latest version. So after i could not find the problem i did a factory reset but it stil does not fix the problem. THe menu stay's a bit blurry/vaguely and also when i start kodi the problem stays. After i switch back to TV on my pioneer reciever the screen is great again. So it seems to be a problem with the Q10 pro, but i am a bit of a noob to find the problem.

Can you guys help me?
