Screen image not showing everything

[EPIC_2]

Hello guys!

Yesterday I opened my laptop to clean it from dust and had to take it apart to the fullest.
After I turned him on again he is not showing everything of the screen.
It's like a part of the screen went outside the display (image is bigger and for example task bar is way lower than my screen is = can't see it anymore)
I don't really know what to do now..
It's even appearing in bios boot and plugging the cables in and out didn't help.

It's an old HP Pavilion G7

Thanks for replies!

Since it happened when you took it apart, go over the screen connections and make sure it's all plugged in properly. Did you check the display settings in Windows? Is it set to the correct resolution and refresh rate (should be 60).
