hello, my problem is the monitor LG M237WA show a 1.5 centimeters black borders
in 1920x1080 resolution, i installed the last driver for HD5770 Vapor-x and catalyst 10.4
Widows 7 not detect the monitor, but with DVI the resolution shows without problems
The problem is with the HDMI CABLE with this conection the problem ocurrs, in 1920x1080 it's shows a black border 1.5 centimeters.
The monitor will have come with a driver CD. Check if you have to install some additional drivers from that CD in order to use an HDMI cable.
If it runs through DVI w/o any problems, then why not just stick with that?
