Vertical Bars

[antonylord]

My system uses a MSI ATI Radeon RX9200SE video card driving my analogue TV (not widescreen) via a S-Video cable.

It seems I have very faint vertical bars - they're wide and move slowly horizontally. They're especially noticeable on dark backgrounds.

I've tried different cables, moving things about, using the same power outlet all without luck - the whole system is on a power filter too.

Is this just noise from the PC power supply? How do I solve this?

Now to silence that machine!

Cheers, Antony.

Did you try a good cable?

I bought thick sheilded cables.

I bought them in the electronic section of Big Lots.
Good RCA cables dirt cheap.
They made a world of difference.

One thing you can try is a different power supply.
It could be the fan in it.

I am having what I believe is the same problem.

Screenshot - You can see one of the bars across the middle of her body and the static at the top. It looks the same in full screen mode, but I windowed it to facilitate taking the screenshot.

I get horizontal lines of washed out color that slowly move vertically from the bottom of the screen to the top. I also get a thin line of static noise at the top of the picture. I am outputting to both a monitor through the VGA port and my standard analog television through the S-Video port in my video card. The lines and the static line are on both the television and the monitor. Also, overall color is more washed out through the card than it is through the television tuner. The wash out is disappointing, but the bars and the static are a definite deal-breaker if I can't get them resolved. Does anyone have any ideas?

Do you guys use Philips tv sets, by any chance? They are known to have these artefacts, in Swedish (directly translated) called "fog pilars"... I haven't found any solution... The fog pilars seem to get better (less noticable) if I use my scart inputs on my tv instead of my s-video input.

Yes, stefan, I do have a Philips tv. I'm in the US though so I have an NTSC tv without a SCART connection. My only options are S-Video and RCA. I don't have an S-Video to RCA cable, but I might see if I can find an inexpensive one and give it a try. Thanks for the information. Any ideas on the static at the top of the tuner picture? It shows on both my monitor and the tv, so it has to be the Hauppage card.

Yeah, the static on top of the picture is closed caption data. It has to be included somewhere, so it is transmitted in the area that is not normally shown on a tv set. You can usually adjust your graphics card settings as to not show the topmost part of the screen. I'm not quite sure, but you might be able to fiddle with settings in config.xml. Do a search on the forums for "overscan".
