9800 Pro TV out, bad?

[I discuss]

I am surprised to see that the 9800 pro TV out quality is really bad,there
is a brighter bar on the screen, very obvious on a dark background, and the
image is kind of washed out...

Is this normal for ATI9800 pro?

All TV out on all cards is shite. Tvs are not a good display for
computers.

Well, for starters, my old card, an Asus V7100 delux combo, doesn't output a
rolling brighter bar on TV screen!

The TV-Out quality on my 9800pro (s-video) is noticeably better than the
TV-Out quality (s-video) was on my Leadtek GeForce3. I'm very happy with it.

I'd suggest fiddling with the overscan, color saturation, gamma, and flicker
filters settings before making the conclusion that the 9800 pro's tv-out is
sub-par.

 

[I discuss]

Really? I am using the S-video too.

The major beef I have is that there is a bright bar (brighter than the rest
of the image) rolling from the bottom of the screen to the top constantly.
it is very obvious on the dark background image.
You don't have that? are you sure?

I will not use overscan, it cut off too much content on a TV screen.
By the way? do you have a full screen image on TV without turning on
overscan?

What do flicker filters do?

I'm very surprised to hear this. I have a 9800Pro and the TV output is very
good with my setup. I'm using the regular line out into a 20 year old NEC TV
and it looks fantastic. I watch DVD's and cable channels that are feed
through my VCR into my Hauppauge WinTV PCI Card. What I find interesting is
that the TV/VCR output is much better on my TV then when viewed on my
monitor. I always thought that my TV card was not that great tell I got my
9800Pro and ran it into my TV. DVD's look crisp and the color's are great.
Sorry your card is having problems. I'm assuming you have an AIW 9800Pro?
Our do you have a TV card ? What is a "brighter bar" ? Have you tried
adjusting the ATI color controls?

Thanks for replying, JLC.
The card is a brand new 128m 9800 pro, not an AIW

Two things I am not happy about the TV out:
1) The image does NOT fill the TV screen, there is a frame around it. if I
turn on "overscan", the TV screen is full, but I lose parts of the images.

2) There is a brighter area scrolling from the bottom to the top of TV
images, noticeable when a dark background is shown on TV.

Since I'm only using my 9800's output to watch DVD's/TV on my TV I set my
monitors resolution to 800x600. Then I switch the output to the TV which
turns the signal off to my monitor. That way the output is easily fit to the
size of the TV screen by using the ATI TV size controls. I don't use
overscan. If you just double click on the TV when you're looking at the ATI
output applet, this will bring up the controls.What are you using your TV
for? Are you outputting DVD playback? Have you had a card in the past hooked
up to this TV and did it look OK? I'm wondering if it might be your TV that
is having the problem. Do you have another set that you could try it out on?
Good luck OK, JLC

Hello Tony,

I own a Sapphire Radeon 9200 videocard.
It is connected to my tv via composite video out because my tv does
not have a s-video in connection. (should buy another tv...).
I am just curious to know if all you guys who connect to the tv via
s-video out have the same irregular s-video out that is on my 9800.
A normal s-video out has 4 -how shall I put it... little holes, like I
find on all other s-video outs, just not on ati (radeon) based cards.
Did you buy your video cables from that one internet address that is
named on the Ati-site? Because that is the *only* address I was able
to find that sells s-video cables compatible with ati radeon cards.
And they seem to be very proud on it. And secondly: why for God's
sake *have* Ati cards such a special s-video out? Just curious to
know!

If you're not using overscan, then you can use the other controls in the ATI
control panel to manually scale the output size to your liking (though it
doesn't work flawlessly, it should get you close). As far as the magical bar
of scrolling brightness, I'd first check to make sure you're svideo cable
isn't defective. Also, depending on the length of the s-video cable, you
might want to invest in a HQ cable like this -
http://www.monstercable.com/thx/productPageTHX.asp?pin=1609 - I'm using the
8-ft'r and it has made a huge difference over my first, cheaper s-video
cable.

Of course, there is always the possibility that your hardware is defective
and or your TV is defective, but we'd want to rule everything else out first
before reaching that conclusion.

 

[Tony DiMarzio]

The female pin configuration on the Radeon is designed to be compatible with
S-Video natively, and with composite via the included ATI composite adapter.
When a standard S-Video cable is inserted into the Radeon, the remaining
unused hole(s) lie dormant and will have no negative effect on the video out
quality. You WILL want to use the included ATI S-Video to composite adapter
if you're using composite, else you'll lose color information.

As far as the web site you mentioned that says it had the only ATI s-video
cables goes, I'd send them a little email for false advertising and
subversive marketing techniques.

That some sort of power supply issue either a problem with the computer or TV

Hello,

try pulling out all connection cables from your TV, except the
S-video cable from your graphics card, this solved the problem for me.

As soon as you connect more than one elcectrical network on my
TV, I get these distortions, I solved it by buying a special
filter and plugging it between my antenna connection and the
antenna cable.

Hi,

yes, I think in english it is called earth loop.
The german word for the device I am using is "Mantelstromfilter".

Earth loops are when you get multiple paths to earth, which can set up
unwanted oscillations. With analog audio applications, it's customary
to set systems up so that earth loops are eliminated: eg, screens are
only connected at one end, earthing is all done through one device
etc. This is because the effects of a loop are immediately obvious:
hum etc. I suppose digital signals should not be so badly affected by
earth loops, but it's certainly not impossible that they would be.

A problem that is solved by disconnecting all leads but one (which
should mean there is only one earth path, particularly if one
connected device is not earthed) and/or the use of a filter (which
might well reduce or remove the unwanted oscillations) does suggest
that earth loops might be involved.

If it is caused by an earth loop, the best solution would be to sort
out your earthing arrangements so as to eliminate multiple paths to
earth.
