I've got an HD card for my computer and a standard 4:3 monitor that's a few years old now. HD content looks pretty good, but I get a lot of noticeable interlacing lines when there's any movement in the picture. It wasn't too bad on the ABC broadcast of Lost tonight, but it was absolutely atrocious on the WB's Supernatural last night. In one particular scene, I almost couldn't tell what was happening because of all of the interlacing. At one point, I ran an s-video cable out of my video card to the TV, and I don't think the problem was noticeable there. It wasn't a very thorough test, so I can't say for sure. But, I'm wondering if this problem would go away with a better monitor. In this one's monitor properties, it lists only two interlaced modes: 43 and 47 Hertz. Only the 43 will display, and it displays this mode in a wider width than the monitor can really handle. I can move the mouse to the side of the screen, and it scrolls the image. The interlace lines do seem to go away, though. I think the top supported refresh rate is 75 Hertz. Would a more modern monitor probably have a higher refresh rate, more interlacing options, and probably eliminate the problem?
