I own a mini desktop pc which is connected to a 1920x1080 monitor via VGA.  At full 1920x1080 resolution everything looks fine.  However, if I switch to 1280x720 I get HUGE 3" black bars on the sides AND 2" black bars on the top and bottom of the image, resulting in a 16:9 720p image which takes up about half of the area of my monitor.  It's as if my desktop thinks that I'm using a 4:3 display and scales the image down to fit.  The same issue does not occur when I connect the same display to my laptop via VGA, so I'm convinced there is a software issue here.

Any ideas?  This one's got me stumped!

My monitor does this if its scaling options are enabled. It treats everything that is not 1080p as 4:3, including 720p.

If this is the problem, the solution is the following:

1. Go to the setup menu of your monitor.

2. Find its scaling options and disable them. Set to full size/stretch/whatever.

3. Open CCC/VECC.

4. Set your resolution to lover than native.

5. Go to My digital flat panels section and enable GPU scaling (maintain aspect ratio)

6. Set your resolution back to native.


Note: You need a digital connection (DVI, HDMI or DP) to have GPU scaling options. It won't work with standard VGA (D-SUB).
