I have a powerbook with an FX5200. The tv I have it hooked up to, (Samsung DLP), is capable of 1900 x 1080, so is the card. But when I switch to that resolution my display gets garbled. Could it be that i need to interlace my video, or is that even possible? The picture even gets screwy in 1900x1080 @ 60hz. Any ideas? Thanks.
