Unfortunatly, that is the limitation of NTSC TV. If you want to get to
1024 res on a big screen, you are looking at getting an HDTV :-( I
believe that NTSC is limited to 320xsomething and just wont display any
higher.
Jason,
Thanks for the reply.
I think that its just that we heard about other cards that for one
reason or another seem to do better for example in a video4linux post
from 9/25/2002 (okay, okay, I agree, I keep my archives too long )
entitled " G400 interlaced TV output" Billy Biggs describes the
G400 as:
....
Ville Syrjälä did some work on the G400: he got the maven registers
set up to put the TV output in interlaced mode at full resolution, plus
he did a kernel patch to give an interrupt every field. This lets me do
cool stuff.
http://vektor.theorem.ca/graphics/tvout/dfbtv/
That is a test application: it takes input from a V4L source (obV4L)
and outputs it to the G400, field synced. The pass-thru output is as
close to full quality as we're going to be able to get. I'm very
impressed. Doing a PVR app is going to be awesome now.
...
Perhaps its just that some of these cards may not be designed/configured to display to TV Out to the best of their ability for one reason or another. I'm basically curious as to what others have found...

Hi,
A friend (Its never the person writing the email right ;) ) is looking
for a videocard that will display at variable screen resolutions (
640x480, 800x600, 1040x780 etc) to regular NTSC TV Out (480i S-Video
preferred interconnection) in such a way that would allow readable text
on the TV.
For instance, his ATI Radeon 9700 while displaying to TV output would
not render readable text on his TV and it would not allow him to adjust
the screen resolution. You can barely read it (Please correct this
statement if he was using the card incorrectly..he was using the S-Video
Output on it). You know that its there, you know where you're going
so-to-speak but you can't see "squat". The reason for the text is to
not have to have a monitor on top of the TV cluttering up the living room.
Any ideas as to what types of card(s) if any would solve this problem?
(Links are welcome)
BTW, this card would be a solution to displaying Divx, Xvid type movies
as played on a PC onto his TV as well as to eventually migrate the PC
into a PVR system down the road ( eventually upgrading to HD ).
Hopefully not too tall of an order...
Sincerely,
Tim Schoenfelder
