SONY 34" CRT Tube HD widescreen KV34HS510 cannot do 4:3 pr..

Archived from groups: alt.tv.tech.hdtv (More info?)

Very odd ?

This KV-34HS510 FD Widescreen CRT Tube television cannot do 4:3
progressive scan images . The image on the screen when attempting to
do this is just visual noise.

For example, on a SONY Widescreen TV, by pressing the "Wide Mode"
button
on the remote there are four options:

WIDE ZOOM: 16:9
NORMAL: 4:3
FULL 16:9
ZOOM 16:9

If the originating media is in 4:3 format, the ideal setting
would be NORMAL.

The problem is for my television, this NORMAL setting doesn't work
if the originating 4:3 source is in progressive scan mode.
This hasn't been a problem in the past as in these cases where
I want to see a 4:3 source from a DVD in 4:3 format on the SONY TV, I
just change
the DVD player setting from Progressive scan to Interlaced and it
works
like a a charm.

However I now have a potentially unsolvable problem in that I bought a
DVI cable in order to generate images from my computer ATI video card
DVI port to my SONY TV DVI input in order to use my SONY HiDef
television as a pseudo flat screen computer monitor.


A PC video card generally generates images in 4:3 format.
The DVI cable from the PC video card to the SONY KV34HS510
works like a charm in in the 16:9 mode: WIDE ZOOM, FULL and ZOOM but
not in NORMAL 4:3. My ATI video card naturally generates images in
Progressive scan
not interlaced format so I get the same fuzzy image in 4:3 mode when
generating images from my PC to my TV. I'm a photo buff by the way
and I like to show digital photos from my PC to my TV just like 1960's
era slide shows I experienced as a kid. An S-video cable has
worked in the past but this is just 480i whereas the DVI cable allows
for more stunning images approaching 1080i (?)

Finally my question. Is there something wrong generally with this
particular SONY
KV34HS510 model in regards to progressive scan 4:3 or is it just my
particular TV that has this problem ?

Do I call a SONY technician to look at this TV or do I arrange with
SONY
to exchange this TV for an identical ( or similar) one that works in
Progressive scan 4:3 mode?

I LOVE this SONY KV34HS510 TV by the way in all other
regards except for this one glitch. I really want to get this TV
working properly with input from a DVI cable working in 4:3 mode
however.

Thanks in advance for any advice or ideas ???

How are you connecting your DVD player to the TV? Svideo or composite? Be
aware, as far as I know svideo doesn't work with progressive scan-you need
to use component.

So you are saying that at one time it DID work? When did the problem start?
Did you change something in your setup?

Why are you trying to display a 4:3 PC resolution on a widescreen monitor?
Set the PC for a 16:9 ratio, I cannot see any reason to be displaying a 4:3
resolution. That way you will fill the whole screen and nothing will be
distorted.

While I could be wrong, I think maybe you just need to learn more about what
you are trying to do. By the way, Sony will have nothing to do with you
hooking up a PC to your monitor. It wasn't meant to be used as a PC monitor
and they just will not support it. Check out some of the web forums and a
utility called powerstrip for more info.

Also, does your TV have DRC mode? I use DRC mode to change my component
480i DVD player (xbox) to 480p.

According to SONY Online Support:

1) SONY does not support PC to HD DVI TV connections and they
recommended that
I disconnect the TV from the PC immediately.

2) Since the KV-34HS510 has a 16:9 aspect ratio it will not support a
progressive
scan 4:3 source input.

So it appears the PC to HD TV DVI cable connection solution in this
case is to get the PC Video card to generate Interlaced video in
4:3 aspect ratio OR configure the PC Video card to use the 16:9
aspect ratio
with Progressive scan. Either situation should work.

As I said the PC 4:3 Progressive Scan to HD TV 16:9 Progressive Scan
using
a DVI cable worked superbly except for the cropped picture on the TV
which
is not ideal as digital photos are usually in 4:3 format.
