Just a quick datapoint. I just installed a cheap nvidia FX5200 card *
(http://www.newegg.com/product/product.asp?item=N82E16814125191) with a
DVI->HDMI converter ($13 from some random seller on Amazon). So far,
I've got it working nicely on my JVC 56G786
(http://www.tvauthority.com/DILA-and-LCOS-TVs/JVC-HD-56G786.asp) . I'm
using the latest 6629ish version of the nvidia driver from portage
(Gentoo) at present.
I was able to get a nice picture using Jarod's generic modeline from :
http://www.wilsonet.com/mythtv/mythhd.php
ModeLine "960x540p" 37.26 960 976 1008 1104 540 542 548 563 +hsync +vsync
I'm still working on testing the HDness of my setup.
Found some HD test patterns at: http://www.w6rz.net/
So, it works for me (YMMV). I _do_ have a problem with overscan. The
TV has a good bit of overscan both during bootup and inside of X. I'll
be playing with modelines to get it fixed in X, but I haven't seen any
way to fix the console overscan.
* The card is 1/2 height (low-profile), but doesn't come with the
low-profile bracket. I had to reuse one from an old 1/2 height card.
Hope some of this helps,
