Well this is unexpected.
Went outside, left computer on for about 40mins (was downloading some games)
Came back
Now my monitor has developed what I can only describe as a grey diffused semi-circular, pencil like smudge starting at the of screen edge, right on the lower part of the monitor (in the middle) extending 2 inches upwards.
Benq 2222HDL (I also updated amd drivers to 12.6 today an hour before this happened but I doubt its that?)
Need some help guys
Thanks
