[mythtv-users] DVI to Sony HS420 series HDTV

[Paul Miller]

I read somewhere that all HD sources use a 16:9 aspect ratio.  My 
television is 4:3.  Should the DVI signal still be 16:9?

Here are some of my results:

1080i (1920x1080 interlaced):  no display; does not appear to be 
supported by ATI's binary driver.  The Windows driver has an option 
to "force 1080i" mode, but it does not appear to work with my 
hardware.

720p (1280x720):  image is left justified, truncated on the right, and 
there are large black bands on the top and bottom.  Using the TV's 
zoom function results in the image being cropped on all sides.

480p (720x480):  image appears to be cropped on only the left and 
right sides, but is fullscreen.

ATI Radeon 9700 AIW Pro with ATI's binary driver 8.8.25 (1/17/05) and 
XFree86 4.3.0.  Display is Sony KV-27HS420.
