PREVENT OVERSCAN ON SHARP LC-42SB45U

I bought a Sharp 42" TV (LC-42SB45U) back during a Black Friday sale for $500 and I've been having a problem with overscan. I don't like to use the Nvidia desktop-resizing tool because all that does is give you a custom resolution. It irritated me that I couldn't get my 1080p TV to properly display a 1080p signal from my HTPC over HDMI. Apparently Sharp TV's are really picky about when they'll let you choose their "Dot-by-Dot" scaling mode but I finally figured out a solution.

I had to go to Nvidia Control Panel > Change Resolution > Add Resolution > Create Custom Resolution > Timing and then select "CVT reduced blank" in the "Standard" drop down. Then Test, accept, ok, confirm, whatever to get back to using that resolution.

After doing that I had a 1920x1080 image that fit my TV perfectly because the TV now let me select the "Dot-by-Dot" scaling mode. So anyway, that should point you to a possible solution if you're having overscan problems.
