Are you by any chance using a KVM switch or adapter on the connection from monitor to computer? Sometimes those prevent the proper reading of information about the monitor and cause issues like that. Try connecting directly to computer instead and see if problem disappears.
I am not connecting trough one of those.
It is connecting directly to the PC. It have the video card that comes with the mother board so no extra video card, also.
TY.

I'm not sure what answer is on this. Maybe someone else knows.
Post back with exact monitor model that you are using. Also, go to Menu -> System -> Create System Report and attach the report it generates to your post for people to look at. Maybe there will be a clue to the problem in the report.
Only other thing I can think of is maybe the cord being used from monitor to computer is faulty. If it is the kind that is not permanently attached to the monitor, maybe you could try a spare cord to connect with to see if that is the problem. (I've had a bad monitor cord myself that caused strange problems.)
Monitor is a Dell E773s
This computer had win7 before, the display/aspect ratio size of it looked fine. I enter the BIOS and it look fine, I don't think it is cable problem.
I really appreciate you are helping me trough this.
I am attaching the report file.
