Have my new 5120 connected to my HTPC via DVI-D. I've used Powerstrip to set my HTPC res at 1:1 (856x480 @50hz) and it looks great As an experiment and cos its meant to support up to XGA and HDTV resolution I tried upping the HTPC res to 1024x576 and 1280x720. I can get the PJ to detect a signal at 1024x576 but I get shimmering blue vertical banding across the whole screen. The bands are very bright and can be seen more clearly on a dark background. At 1280x720 I cant even get the pj to detect a signal. I've logged this out to Benq but had no response yet. Anyone have any ideas why ?
