Thanks in advance to anyone who may be able to help. HDTV = Sony KV32HS500
which is suppose to have 1080i capability. Video card = ATI AIW 8500DV with
DVI output and component video output (via ATI dongle). When I use DVI,
resolution is limited to 640 x 480. Someone on this newsgroup recently
recommended selecting a Sony monitor (GDM-w900) as my output device. This
allowed me to chose a resolution of 1280 x 1024 (my HDTV has a 4:3 aspect
ratio). This was much better except that the 1280 x 1024 only fills up the
central area of my HDTV screen. I still get black lines on the top, bottom,
left and right sides of my screen - these are unused portions. Any
suggestions out there? I tried using powerstrip but that didn't really seem
to do anything useful. When I use the ATI dongle for component video output,
my display is always in 16:9 aspect ratio (for example, 1152 x 648) which is
not useful.

Have you tried using DVI for the connection instead of component?

I'm in the same group as you. I have the exact same TV except I'm using
an NVIDIA card with DVI output (not that it makes a difference). From
what I have determined, you are stuck at a ?x480. If you go higher, it'll
change the horizontal sync rate from 31 hz to 33.5 hz which will trigger
the TV to go into 16:9 mode. So if you're looking for a 4:3 resolution,
you're stuck with 640x480, 720x480, etc.

The TV can do other resolutions such as 540p, 720p, and 1080i, but they'll
be letterboxed 16:9 resolution.

We're both out of luck when it comes to 4:3.

I have a KV32HS500 as well and I'm having a horrid time trying to set
up DVI with. Where can I find a list of all the available resolutions
(with timeings, h/vsync rates etc.) And am I to understand whenever
the hsync goes over 31 I'll get those ugly bars?

Is anyone else setting up a DVI connection to this tv on linux?
