My monitor flickers and the width is narrow

if I hit the monitor it goes back to normal for a while...I tried to adjust it etc, I am
getting very discouraged....

is this a sign

a) bad monitor
b) bad video card
c) my eyes or my brain is defective

Also , can a monitor be fixed or just toss it out with my TV?

 

your monitors electronics is broken, i think.
does it run ok when you switch to a low resolution (800x600 or so)??
i think it can be repaired without too much fuzz.

 

not worth fixing unless some kind of special hi $ monitor. buy a new one. they are so cheap now.

 

If it improves when you hit the monitor the its the monitor, if its better after kicking the computer , probably the video card ( without getting highly technical).

Reconnect the video cable but sounds like bad monitor.

 

LMAO...classic stuff.

try de-gaussing it first from the monitor menu...
