I have a new Compaq desktop to which I have added an ATI Radeon X1050 PCI Express video card.
It is hooked up over the DVI to my Panasonic 42" plasma.

I have set the resolution to fill the screen, however I can't see the edges of the screen on the TV. For example, I can only see the top 1/3 of the taskbar and can't see any of the minimize, maximize, and close icons in the upper right so corner.

Is there any software which will allow me to adjust the output from the video cards so as to shrink the screen?

On a related note, the computer will not boot unless I have a monitor plugged into the VGA port on the card. does anyone know what is causing this or how to work around having a second monitor by my TV?

Thanks.
