Based on your suggestions, I played around with my settings last night to see if I could improve on the extremely poor s-quality I'm getting out of the FX5600XT (possibly a Gigibyte card) I put in last week. Compared to the onboard Nforce2 quality I was getting, it sucked! So, beware, I believe that it varies from manufacturer to manufacturer. and was really happy with the results, so I wanted to respond, so maybe more people would see your advice. I'm not sure I could tell much difference by setting the overscan to 250. It was just very slight on my card/tv. But, setting this made me adjust my GUI size IN MYTH SETTINGS/APPEARANCE down to ~540x750 and set the offsets to X = 15 Y = 20 so that everything stayed on the screen.

Scrolling text used to be fuzzy, but now is crisp -- almost too much with a harsh edge. The Flicker Filter made the biggest difference. I get a bit of flicker in the horizontal lines in the GUI, but that is expected on an interlaced TV. To control this somewhat, I have my Flicker Filter set to ~12. Turning up the Saturation helped a little to improve the vibrancy, but this card isn't a good judge of color. I have a new MSI FX5200 coming today from newegg; will play more this weekend. Thanks for the (as always) very good suggestions, -rac _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
