I didn't do any research on cables, and used one I had bought a few years ago for an lcd monitor. It was probably the cheapest one I could get at the time. I don't have any issues with the display, some motion problems with live programing, but that is a software, or pc hardware issue. Myth displays wonderfully. I used a modeline from an email to this list from Jarod. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Yes, but that Webpage is almost certainly assuming 1080i on the part of the reader. I figure that if my card can do 1080p, and the monitor can do 1080p (and, of course, all LCD panels are by definition progressive devices, whether or not the input signal is such), so I'd want the connection in between to be able to handle 1080p.

I've been playing a lot of 1080i content from my PC using Windows Media Player 10, and I have not noticed the problem you're describing here. I do, at times, see my video and audio stutter, but I believe it's due to CPU and/or HDD I/O -- most likely HDD I/O. The stutter is very occasional and only lasts for a split second. The PC I'm using is slower than yours, also. It's a 2.4GHz P4 w/1GB and an nVidia 5700 Ultra. Being that it's only affecting a small portion of your video, I have a feeling your problem may be due to deinterlacing. Perhaps you can try disabling the deinterlacing option to see if it remedies the problem. > 2) /var/log/Xorg.log tells me that the card has a single link >connection to the display.

Based on the information I read here: http://www.datapro.net/techinfo/dvi_info.html#Page03 I don't think a dual-link cable would do you any good, as the monitor can display a maximum resolution of 1920x1080. I'm sure that using a dual-link cable shouldn't hurt, but I don't think you'll get any benefit from it. - Ken ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

It may also be your tv trying to do double duty in i->p conversion? from what I remember people here saying, that TV accepts 1080p signals, does your tv show that it is accepting your computers signal as progressive? > 2) /var/log/Xorg.log tells me that the card has a single link >connection to the display.

Whether it matters I'm not sure. Your TV would definitely have to support dual link, which it should, and the video card would as well, which I'm not sure of. If they do, in theory the picture quality will be better as more data can be sent... I have no experience in practice with this though, but at the price ramelectronics.net and some of the other quality online cable stores have DVI-D dual link cables for, it might just be worth buying one, testing and returning if the results aren't worth the price you paid. -- Steve ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
