[QUOTE="KevL, post: 385234, member: 11798"] Hi Jameson To be honest I've given up trying to understand what actually goes on when a pc outputs video. I think my problems were down to "bad" bios version and/or catalyst drivers. Now that I have version F7 Motherboard bios and Catalyst 9.2 drivers the picture passes the bloomberg test whether I set screen res to 720x576p @ 50Hz by HDMI or 1280x720 @50Hz by HDMI. Not sure about de-interlacing versus scaling error on my previous combination of bios/vid card driver. Pic was OK at 576p out but bad at 720p out. Presumably the deinterlacing is done before scaling???? The difference was then only the scaling???? Anyway I'm getting a really nice picture now and have screen res set to 720p. This is having no effect on video quality but the MP menu is a tad sharper (noticable on fonts etc) at 720p c.f. 576p (for obvious reasons). Kev [/QUOTE]
