Re: A10 w/GT2560 V3 replacement LCD showing black bars?

Underscan occurs when a video signal does not reach the edges of your monitor and leaves a black border around the image. Normal broadcast TV content is "overscanned," meaning the image bleeds/scans past the edges of the screen so it fills the entire monitor.
