I have been able to get some pretty good results with SDTV and/or DVD playback @540p Powerstrip timings. However, I have been unable to generate a 4:3, 1080i configuration (e.g., 1440x1080). Is this even possible? I notice that even the ATI Radeon/Powerstrip guide at the top of this forum doesn't list any "true 1080i" modes for 4:3 HDTV sets. Also, even if possible, would I gain much in PQ with 1080i vs. 540p during, say, DVD playback? I have a 32" display.
