[QUOTE="mowog, post: 19320, member: 12370"] Outputting component video from a PC graphics card is a pretty challenging exercise. My setup uses a GigaByte ATI x300 card, and a custom VGA -> SCART cable to connect to my Sony SD widescreen TV. Because the TV is only SD I've not attempted any HDTV resolutions, and because the ATI cards can only reliably output NTSC resolutions I have my HTPC running at 856x480@30Hz with Powerstrip. Even at a sub-PAL resolution, the picture quality is amazing; far better than you can get using an S-Video TV-out. The TV you mention has a vertical resolution of 1080i (interlaced) or 576p (progressive scan). You *will* be able to output those resolutions from an ATI 9800 Pro, but it can take a fair amount of effort to make it work. How you do it depends on what inputs your TV has -- in my case, I had to make a custom VGA -> SCART cable, and then connect it to the DVI port using a DVI-I -> VGA adapter. If your TV accepts 3xRCA or 3xBNC inputs for Y/Pr/Pb then the ATI HDTV adapter is your best bet. You'll probably still need Powerstrip, though.. even though the Catalyst drivers have HDTV support. Either way, you won't find a PC graphics card with native PAL resolution support -- they simply don't exist. You *will* be able to make an ATI card do the job using Powerstrip, but as I said above it takes a lot of patient fiddling and experimentation, *and* a willingness to destroy your TV in the process with way-out timings. Anyway, here are a few links to help you on your way :) [url=http://www.avsforum.com/avs-vb/showthread.php?s=4f4908ba0ba60ad91b168b67b0ff0292&threadid=206854]Custom resolution guide for HDTV-POWERSTRIP-RADEON[/url] [url=http://www.avsforum.com/avs-vb/showthread.php?s=&postid=1737825]HOWTO: YPrPb component output on any Radeon for under $5[/url] [url=http://ryoandr.free.fr/english.html]VGA - SCART cable guide[/url] [url=http://www.avforums.com/forums/showthread.php?t=136811]AVForums - VGA->SCART RGB[/url] Good luck!
