Hi all,

I have a PC running WinXP and containing an ATI RADEON X850 XT video card.  I recently purchased an RCA HDTV that I am also using as a monitor on the PC.

When I tried using the TV's VGA connection, the shadowing and distortion was so bad that I could quickly see it wasn't going to be usable.  So, I purchased a DVI-to-HDMI cable and connected the PC to the TV that way.  The display now looks great, but a new problem was introduced that I've been dealing with for a few weeks, and that I'd like to resolve if possible.

Since connecting the PC to the TV via the DVI-HDMI cable, the display is a little "too big" to fit on the screen.  In other words, any icons that I have in the far-left position on my desktop are about halfway off the left side of the screeen, part of the taskbar is pushed off the bottom of the screen, etc.  Unfortunately, the TV does not have any built-in functionality for adjusting the screen size and positioning under its HDMI menu like it does for VGA.  I've tried using some screen adjusting options within the software for my ATI card, but they also don't seem to have any affect on the HDMI connection.

One additional oddity that I'll mention that may or may not have any bearing on this problem is that when I set my PC's display resolution to the "native" resolution of the TV, the display is so blurry that I can't read it.  I actually have to set the resolution to something a bit lower in order to get a clear display.

Can anyone tell me what I could try in order to make the display properly fit on the screen?

What you are seeing is overscan on the TV. TVs usually display only about 95% of the image they are presented (called overscan) so that the video noise at the boundaries of the image are not display. This works well for TV signals.

For PC's of course you want to see the entire image.  You have overcome the major obstacle in getting a PC image to the TV - that is getting to work over HDMI.

Then use the Catalyst control center software to adjust for overscan, Check here

Thanks for the help.  I updated my ATI Catalyst software to the latest version, and this time I figured out how to use it to adjust the screen size.
