I recently bought a new PC and monitor and after hooking it up I noticed all my electronic (video) equipment were having graphical/image problems.

First off any form of video on the PC (streaming/downloaded/dvd/games) have lots of motion artifacts and/or blurry/sluggish/poor quality picture. The PC (HP slimline) and monitor is Samsung 226cw. I checked on my old Toshiba laptop and saw that was having the same issues.

At the time I thought something was wrong with my new comp., but then I noticed that my tv (JVC 27in) was showing lots of motion artifacts as well. Its not as bad as the pc but still noticeable esp. on sports games. I have Comcast cable.

I then tested my HD DVD player and XBOX 360 (using my Sanyo Z3 PJ) and to a lesser extent saw the same problems. On 360 games jagged edges were much more visible, and some colors looked off and blurry. On the HD player standard def movies looked horrible even being upconverted, and on high def movies looked slightly downgraded but ok.

I have no idea what is causing this, although it did start when I got the new pc. I unplugged it when I was running the PJ but that didn't do anything. I was thinking that maybe it was some kind of electrical issue. I have everything on surge proctors but they are old and not top shelf. Also I live in an apartment so could it be some kind of interference from neighbors equipment.

Has any one herd of this, or have any ideas how to solve it?

Is your laptop having the issue when it's only running on battery? Ie, not plugged in.

Yeah, but it's old and doesn't run well on the battery alone.

Your new PC probably does not take the interlaced video from an ordinary DVD and make good PC video (progressive) frames out of it. This is the primary source of motion artifacts.

Inside a DVD player, making progressive frames (de-interlacing) is step 1 and upconverting is step 2. Trying to do both steps at the same time gives poor results. If step 1 is done poorly, step 2 won't fix it.

Depending on its size and how finely focused the electron beam is, an ordinary analog CRT TV displaying ordinary interlaced video may show motion artifacts all the time to folks with really keen eyes.

Putting interlaced (and un-upconverted) video from an ordinary DVD player into a Sanyo 'Z3 should give good results as I am told the 'Z3 does the above step 1 quite well for SDTV. I'm not sure about 1080i input which also needs step 1.

Your new PC may also not have fast enough software if not a processor chip to keep up with the motion in the video subject matter.

A weak battery is probably not the problem if this is your laptop.

Component video cables that worked fine for SDTV can leave you with ghosts, a softer overall picture, and/or smeared colors on HDTV material.
