In order to rid most of the rainbow effect, I am planning on running dlp projector from HTPC with a higher refresh rate. Perhaps 72hz or 85hz??. Infocus never put there max v-sync range in their tech specs??. Anyone have experience with this projector (LP-340) running from a HTPC at higher refresh rate??. What was the fastest you could go up to and doed it make a difference to rainbow or does the projector just downsample it back to 60hz regardless. Also for DVD only, is there a big difference from SVGA to XGA ??
