Hi guys,

I have strange artefacts when playing video or TV. Sometimes they are hardly to recognize and some other times they are very prevalent. Video-Resolution is PAL.

An artefact looks like a vertical stripe of about 20 pixels width that is a little bit darker or lighter than right or left of the stripe. The stripes goes from the top to the bottom, all have the same width.

My screen is completly covered from the left of the right with theses stripes. All have the same width like this. The width of the strips DOES NOT depend on the zoom-mode.

Normally you don't see these stripes, but sometimes one of the stripes really a bit darker/lighter than their neighbor and you see it.

I don't think that it's an MPEG-artefact since it does not depend on the zoom-mode.

Update: When I increase the resolution to 1024x768, they disappear... Why?

Regards & thanks for any help.

Daniel

What TV do you have? I had the same thing with my LCD TV when I first got it. Was driving me mad and only occured at its native resolution. I am using VGA input though.

I eventually narrowed it down to being my gfx card output a less than ideal signal on its analog port. I would assume isolation being the cause there. I now use a dvi 2 vga adapter and use the dvi port of my gfx and I have a perfect picture. It could also have to do with a low budget cable offering not enough isolation. Upgrading my cable at first brought some improvement.
