I bought an Acer H233H and have it connected to my ATI 4870 via HDMI. The resolution on the monitor is 1920x1080. I set the display resolution to this setting, but the image of the desktop does not fill the full screen. Instead the desktop is framed by wide, approx. 1 inch, black margins on the screen. It seems my card is stuck on 1680 x 1050. But soon as i remove the HDMI cable and put DVI.. the screen is normal..
can some one pls help me
Does anyone know why my graphics card is doing this?
