Problem: Recently I added a 47" LG tv as a 2nd display on my computer and the display is off centered. A black bar approximately 1 1/2" thick on the left hand side appears.
Set up: ASUS essentio CG5290 purchased back in 2009. I have a partitioned hard-drive which has 2 operating systems. Has a Nvidia geforce gtx 260 graphics card. The monitor that came w the computer is a 24" display hooked up via DVI cable. The 47" lg tv is hooked up via a DVI-to-VGA adapter to a vga cable.
What I have done: Below is a list of attempts that have not worked.
I tried unplugging and replugging my cable from my comp to my TV.
Changed the tv as the primary display.
Had the tv as the only display.
Used the Nvidia control panel "adjust desktop size and position" function. This will move the screen over giving vision of the right hand part of the image, but the black bar remains.
Changing the resolution from the Nvidia control panel only changes the size of the black bar. (800x60 is currently the only setting that will get rid of the black bar completely, but that defeats the purpose of having the tv)
Other info: At startup even when the tv is not the primary display, the first few screens before I select which operating system display on the tv. This is the only time the black bar does not appear. After I select the operating system to run, the black bar appears.
black bar on the left side of 2nd monitor wont go away.
