My computer, HP a6110n, only has a VGA connection. My moniter HP w1907 has input for VGA and DVI.
What I'm thinking about doing is replacing the video card with this one:
The question is, would using DVI improve playback quality of videos and be worth the investment in a
new card? Or possibly an even better card? Also, I want to avoid replacing the 250w PSU.

Bartman, if the only reason to replace the graphics card is the monitor, I don't think it is worth it. I have the exact same monitor (HP w2207) on 2 different systems. One with a VGA attachment and the other one with a DVI attachment. To tell you the truth, I cannot make out any difference. I had also hoped that there would be a difference (although the display quality of the monitor is excellent in both cases), but that was not the case.

OK. That's good to know. I would hate to spend the money ( even $20 ) if it won't make an appreciable
difference. As you said, the display quality of the monitor IS excellent. Text looks fine, but DVD
movies are grainy compared to my HDTV. Just thought DVI might help with that. But I will trust your judgement on this since you do have the same monitor.

Thanks, Bart

Your DVD movies may be grainy because they come in a Codec unsuitable for the system. I would ask ScottW - he knows this stuff. But I have to tell you that I have never played DVDs. So on that part, I cannot really make a judgment. Maybe someone who has done that should voice an opinion.

Bart, your LCD display is better for static images then for moving ones. Also, consider that DVD movies are stored at 720x480 resolution (NTSC) so to be displayed on your monitor at 1440x900 (native), the individual pixels have to be quadrupled in size. This increases the blockiness of the image.

Your HDTV, even if it is also an LCD, will use edge-softening to reduce the blockiness of the image. Analog displays, such as CRTs, have a natural image softening effect that most people find pleasing. Your living room HDTV would probably not produce text that is as sharp as the computer monitor. These monitors have different purposes and, by default, are adjusted to suit the primary use.

Amazing ScottW. I knew you would have an explanation, but how did you learn all this stuff. I better get on the ball because else I will die dumb - lol.

That's what I suspected and I'm glad we have someone like you who is knowledgeable in this area.
Thanks to you and again to whs. You both prevented me from spending money unnecessarily.
