Cannot display this video mode

[Johnz]

When i turn on my pc, theres error appear 'Cannot display this video mode, change computer display input to 1920x1080@60hz'. I am using 1920x1080 before this happen.

this happen only when im using graphic card as my display. I can enter bios but theres some green line on the interface as u can see in the picture.

Have you tried a different monitor or a TV?

not yet. No extra monitor

the green lines can be the result of a bad cable or just a loose connections.  They can also be from gpu problems.  I would start by swapping out the cable or trying a different connection on your gpu. 

 

Also is your card a 290 flashed to a 290x or is it actually a 290x?

 

And if you cant get into windows because of this you can boot into safe mode and remove the drivers and it should work after that
