I'm now running 2X 22" LG Monitors on my PC, but one of the monitors isn't displaying correctly... 1 monitor is an LG 22EN33 connected to my R9 290, using a VGA to DVI adapter, and the 2nd monitor is an LG 22M45 connected to the same card by a HDMI cable. Now, my 22EN33 is displaying at 1920x1080 and is using up all of the screen, however when I try and display my 22M45 at 1920x1080, the display just gets a black box around it by about an inch each side and won't take up the full area. To make it fit I have to display it at 1680x1050 and it looks awful.
I've tried using the driver disk that came with it but it didn't help, AMD Catalyst Control didn't help and neither has window's own display control...
Both screen's are 22"s, both are LED, both HD and both LG but only one is working correctly
In AMD CCC go to the "My Digital Flat Panels" tab. Then click on "Scaling Options", select the monitor that has the black bars, then move the scaling slider. This should stretch the 1080p image to the borders of the screen properly.
