Hello to anyone who views this,

Whenever I put a game in fullscreen, purple and other colored lines pop up and it becomes unreadable... I tried other resolutions and they all do it... The weird thing is that some games (like the stanley parable in 1080p) don't do it and others (like serious sam 2 or just cause 2) do it...

Graphics card: Amd Radeon hd 5040

Windows 10

Intel core i7 870 2.93 ghz
(keep in mind i dont know what that means... lol)

6gb ram

my monitor is an acer h243h



I thought it was my graphic card at first, but on youtube people are playing games on fullscreen using that card...

As soon as i put the game in windowed mode (big or small) the glitching stops...

My monitor is plugged through an hdmi cable...

The glitchy lines are not plain colors... you can cee the came and the colors change... It feels like playing on a one million year old screen inverted color screen...


Thank you for any help...
