[mythtv-users] pcHDTV and HDTV

[Steele Price]

set proper modelines and possibly adjust your TV in Service mode to
reduce/increase overscan and there are no black borders, the biggest problem
I have is in 720p, My Sony had WAY too much overscan (like 30 pixels per
side) and I still need to adjust that out in service mode, but in the short
term, I just made settings to Xine and MythTV to use a borderless window
mode instead of fullscreen.  I don't notice any real difference except the
size is now perfect with 2 pixels of overscan.

You can spend a week trying to find information on AVForum, I think I spent
even more, and it's 99% windows based using powerstrip.  I have all the
modelines needed for any standard broadcast resolution and will have them up
on my website in a day or 2.  These were the most difficult thing to find,
modelines that actually worked and didn't destroy the tube by setting a vga
refresh rate.

I tested alot of different resolutions, 1080i, 720p, 480p, etc.  and decided
that 720p was by far the best looking and most consistent. there is great
debate over 1080i vs. 720p, but if you want to see any text from your
computer, you won't be wanting interlaced anything.

I've done some of the research, but no real world testing. AVForum is a
good place to try to find people who've done it. In fact there's diy
instructions for making a component converter there(though I haven't
been brave enough to try it yet) If you're building a box around it and
want widescreen, my suggestion would be for an NVIDIA MX series card,
since they support widescreen resolutions and have acceleration for MPEG
files(which is currently being worked into Myth). Once XVMC is fully
enabled in Myth a rather slow 1.2 Ghz machine should be able to do 1080i
no problem. I'd love tohear other people's take on this though.
Especially anyone running a VGA to component converter into a widescreen
HDTV. I'd love to know what's needed to ensure there are no black
borders. Anyway, keep us all informed on what you find out and I'll do
the same when I finally break down and buy a converter myself.

This is encouraging.  I've been waiting for a card like this for many
months now.  Now that is available and a known commodity, I can start
planning a machine around it.

One question I haven't done much research on, not directly related to
the card but never the less very important...
What output options are there to drive from a graphics card to a HDTV
using component cables?  My HDTV doesn't have DVI inputs, so I need
either a card or converter with component outputs.  If its a native
video card, then I assume it has to be running in the native
1920x1080 interlaced mode?  Etc, etc, etc.  Again, it may not
be a big issue, I've just haven't done the research yet.

Thanks,
Brian
