Post subject:	Changing from S-vid to DVI
Sorry if this is in the wrong forum, it seems there may be a couple of overlapping choices. I have a pretty much stock R5F1 install running a GeForce 6600 connected to a Sony TV (36HS-510 as I recall) via the card's S-Video -- there's no 'proper' monitor. I want to upgrade the configuration to connect via the DVI connector. (I've confirmed that the TV can accept the connection if I can figure out how to make xorg drive it...) This is my second step in converting my KM Box to HD. (The first was disk space, the next would be tuner.) The problem I'm having in looking into this is not in finding information, but rather quite the opposite. There seems to be too much out there. From what I've been able to distill, It sounds like 'all' I have to do is: get the right mode lines for defing the video modes. setup the front end to change modes for the source resolution. I know the TV can do 1080i and 720p, but I've heard people complain about the video when driving 1080i. I know the set can NOT do 1080p. The tube is a 4:3 that can do the "squeeze trick" so I want 4:3 material in 480 otherwise the squeeze kicks in, and it's like watching a 17" set. (I think 480p is ok, but higher resolution kicks in the squeeze.) Sooo, my questions for the experts here: Is it worth going 1080i or should I stick with 720p? Are there other files to back up first? Does anyone have a working xorg.conf that would speed me on my way? I don't need to reinstall KM do I? Any other tips??? Thanks. Joe

I've just taken the jump from an SD s-video telly to an HD HDMI telly (a 32" samsung). Litterally, 10 minutes ago... YMMV, Mine's a 16:9 LCD, so your's may be different, but here's what I did. Find the resolution for the telly: It was in the manual, as it's a standard LCD mine's 1366x768. Find modeline(s): I went to the mythtv wiki, where people have posted modelines, and I took anything that was 136x768. I say 136 because I've heard some people having better results with 1360, and there were a few 1368 ones on the page too, so I took them all, and I ended up with a list: Code: Modeline "1368x768-1" 85.478 1368 1424 1536 1792 768 771 777 795 +hsync +vsync Modeline "1368x768-2" 85.478 1368 1424 1536 1792 768 771 777 795 +hsync +vsync Modeline "1366x768-3" 85.500 1360 1440 1552 1792 768 771 777 795 +hsync +vsync ModeLine "1360x768-4" 85.5 1360 1424 1536 1792 768 771 777 795 +hsync +vsync Modeline "1360x768-5" 84.50 1360 1392 1712 1744 768 783 791 807 +hsync +vsync Modeline "1360x768-6" 85.50 1360 1476 1588 1776 768 771 777 795 +hsync +vsync Modeline "1360x768-7" 85.5 1360 1416 1528 1792 768 771 777 795 +hsync +vsync Modeline "1360x768-8" 72.000 1360 1424 1456 1560 768 771 776 790 -hsync +vsync ModeLine "1360x768-9" 84.6 1360 1424 1568 1776 768 769 774 795 Modeline "1368x768-A" 85.50 1368 1478 1590 1776 768 771 777 795 Modeline "1360x768-B" 85.500 1360 1432 1544 1792 768 771 777 795 Modeline "1360x768-C" 84.50 1360 1392 1712 1744 768 783 791 807 Edit Xorg.conf I then inserted these into the monitor section of my xorg.conf file, and also edited the screen section to look like this: Code: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultColorDepth 24 SubSection "Display" Depth 24 Modes "1368x768-1" "1368x768-2" "1366x768-3" "1360x768-4" "1360x768-5" "1360x768-6" "1360x768-7" "1360x768-8" "1360x768-9" "1368x768-A" "1360x768-B" "1360x768-C" EndSubSection EndSection I also commented out my "ConnectedMonitor" and "TVOutFormat" options in the xorg.conf. Connect the telly I plugged an HDMI > DVI cable into my telly + 6600GT in the myth box Rebooted, and it worked. The details my be different for you, but the process should be similar. Good luck, I'm just stunned by the quality of my set, it's lovely
