After playing with 3 different NVIDIA cards and various driver revisions, I am starting to wonder, "Am I better off with an ATI card?" I Have my MythTV system attached to a Panasonic HDTV Tube via DVI, and also have an AudioAuthority 9A60 VGA->Component adapter available. So far, I have had nothing but bad luck with the NVIDIA cards, because of the following factors:
1. My Panasonic HDTV requires HDCP on the HDMI input, which I connect to with a
DVI->HDMI cable.. This limits the cards that will work to the 6xxx and 7xxx product lines.
2. Version 7667 (at least) and above NVIDIA X11 drivers have an issue when used with the
9A60 where the screen is wrapped half way around the screen (i.e. the
left and right edges meet in the middle of the screen). This means I can't use the 9A60
with the 6200 card.
3. Version 7XXX and above drivers also have broken support for VBLANK sync. This pretty much
precludes using my NV6200 unless I can live with the tearing.
I've tried installing both an 5200 and 5500 series card in the same system with mixed results. While the 5500 worked as expected with the 9A60 and 6629 drivers, the video quality so much worse than the 6200 card with the 7667 or 8174 drivers that I couldn't live with it. The 5200 card was less cooperative, and would just lead to a black display when X started. Everything was running as expected, I just couldn't see it.
Given all of this, would I be better off getting a cheap ATI card for this system? I've seen a few mentions lately of people using ATI, which I know has been discouraged historically, but seems to be becoming less of an issue.
Anyone have any experience they could share?
Thanks!
