TV-Out problem


D

Dan K

I have an ATI Radeon 9800 Pro which has been having problems with the
TV-Out capability. ATI has been less than helpful in trying to help
me resolve them. The issue is the quality of the picture is very
poor. Before anyone interjects and says TV-Out quality is normally
poor, I am aware of that, but it is even worse than it should be.
Specifically what I am seeing is as follows: While the PC boots the
TV-Out quality is as expected. I can clearly see my POST and early
boot-up sequence. The Windows XP splash screen looks perfect, than
right when the scrolling progress indicator on the splash screen
pauses (mine always pauses for a split second after being up for a few
seconds.) the picture becomes very snowy. Shortly thereafter the
picture goes away entirely. Now this happens whether I have any ATI
specific driver loaded or not. (That is to say, even with no ATI or
Windows drivers for the 9800 Pro loaded, I get TV-Out up to this
point.) If I do have the latest 9800 Pro drivers loaded, I must
enable TV-Out from the driver control panel, however the quality is
still very poor as mentioned above. I had a 9700 Pro in the past
which seemed to work fine (except it would overheat so ATI sent me a
new 9800 Pro replacement)
Additionally, after messing around with it for a while, I decided to
re-install Windows from scratch. Everything worked perfectly for a
few weeks (including TV-
Out) but then just today, the problem came back. There is nothing I
can put my finger on in terms of software I have installed, or driver
updates I may have gotten to cause the issue. I have obviously
re-installed all the video drivers to no avail. I have also
un-installed anything I could think of since It last worked. No dice.
Tried restoring to a restore point where I know it worked, still no
help.
If anyone knows of any issues, has seen this problem before, or has
any info on how I can proceed, I would appreciate it very much. I am
a software engineer, so no need to dumb it down for me.
I am currently running SP2 with all the latest updates. However as
mentioned before, I have not updated Windows in the recent past so it
did work with SP2 installed previously.

Just an idea:

Check the frequency. on the back of the tv it will say 120 volt, 60hz ,
make sure the frequency is set the same on the computer.

The reson it may be clear while booting is the system uses the bios
defaults, then widows takes control once its booted

control panel>display>settings>advanced>monitor

Thanks John, but the 9800 Pro (and most newer video cards) have a
seperate DAC for the TV-Out (S-video) connector, which is forced to
60Hz, regardless of the frequency of the VGA output. Besides if the
frequency weren't matched there would be an even more pronounced
problem such as scrolling and tearing of the image, not just a snowy
image.
Thanks for the idea though, glad to see some good feedback.

Quick update...
It appears the problem is caused by my Sound Blaster Audigy. It turns
out if I disable the digital audio output on the Audigy (which by the
way is connected to the same amplifier that receives the S-Video
input) the problem goes away. Of course now I don't have sound!
(Simply disconnecting the RCA cable accomplishes the same as turning
it off in the driver.) The reason it worked for a while was because I
just recently reconnected the digital audio output after re-installing
Windows. (It had been connected for over a year with my 9700 Pro and
worked fine.) Therefore it is my conclusion that there was a hardware
redesign between the ATI Radeon 9700 Pro and the Radeon 9800 Pro which
made the S-Video output more susceptable to interference. Now why the
Audigy card is causing this interference is another good question. I
doubt neither Creative Labs, nor ATI will take any responsibility for
this issue.
My next step will be to attempt to connect everything into the same
outlet (computer, monitor, amp, tv, etc.) to prevent any ground loop
possibilities and see what happens.

Later,
Dan K.

You are as full of shit as the idiot who told you to check the ****ing mains
frequency, you dumb ****. If you actually bothered to read, you'd note
that's what he was telling you. You're just spouting words to make yourself
look good because you've got a mad idea in your head about the cause. No
doubt it's because you are simply unwilling to admit that you've got cheap
shit kit with equally cheap shit chipsets that are susceptible picking up
buss noise.

London to a bucket of shit says you have a cheap shit motherboard with some
cheap shit ALi, SiS or VIA crap on it.

And if that's not true, London to a bucket of your mashed brains says you
think the 9800 Pro, or any ATI card for that matter, is a worthwhile waste
of money.

Offload the ****ing thing to some other idiot on eBay and get a real video
card. Like mine, for example. ASUS V9999 Ultra. **** me dead, even the lowly
nVidia FX5500 shits on the AT 9800 series. I know. I just threw my old ATI
9800 XT into a linux server. Command line work is all the ****er is good
for.

entertaining and makes more sense.) I looked in nanau last night,
but didn't see any mention of them." -- Ron Sharp

You May wonder if they are simply unwilling to admit that they have
got cheap shite kit with equally cheap shite chipsets that are
susceptible picking up buss noise. But that does not make it so.

ATI cards ARE COMPLETE AND UTTER SHITE (and they know it)

AVOID THEM!(rip off merchants)

stick to nvidia (a superior product)
