If it were related to the bandwidth of the video card being the bottleneck due to slow hardware or outdated drivers I would have expected the embedded Intel graphics on my buddies computer which uses RAM for video memory to be much slower than my Asus 8600GT w/256 megs of video RAM and always up to date drivers. Both of us are running 720P out of the PC's since 1080P is too small to see anything very well when sitting on the couch so you could say this is right in my graphics cards resolution/performance sweetspot but his wasn't too shabby either. I would expect a bit of video card bandwidth limiting with my setup on 1080P though. My buddies setup clearly does better motion. Admittedly my setup is not the absolute latest and greatest but it's a pretty screamin card that does much much better on this particular test when feeding a CRT at a similar res instead of this LCD.
To really see it you have to wiggle a window around pretty quickly. I just tried it again and definitely see multiple outlines of the edge of the window closely trailing behind the real window and quickly disappearing when I shake it around quickly kind of like that old mouse trailer effect windows used to have. When I plug in the CRT and do this it's a nice crisp clearly defined edge no matter how quickly I move the thing around.
If you want to see something really gross put your video card in interlaced mode instead of progressive mode.
This isn't the only test that shows the motion blur. Panning movie scenes etc also highlight this shortcoming of LCD's. It's actually a pretty well known problem of this relatively slow technology. Think of it like this: why else do you think we are limited to 60Hz refresh rate max while best CRT's are up in the hundreds of Hz? They are getting better all the time with this but last years tech like my Aquos are definitely not up to what CRT's are/were capable of in their heyday.
Check out the Wiki link below. It's not too bad and notice the star of this blur page seems to be LCD screens with nary a mention of plasma and no mention of DLP. Note that they also seem to hold CRT as the reference to shoot for with respect to blur. Note that I wouldn't consider wikipedia necessarily a final arbitrar but this time it seems to correlate well with my own understanding.

Thats still a nice card you're running. I run my display at 1080p as the 720p looks fuzzy too me on my Sharp 52 inch Aquos. My Plasma which has a native resolution of 720p looks great when running the video card at 720P. I use a Nvidia 8800GT 256 bit with 1 Gb of ram... Smokin card by the way!!!I get to look at the Mits DLPs on a regular basis as I install them from time to time in customer's homes. I admit I'm not a big fan of these TVs. They look dim too me.
For someone that wants a large screen for cheap..they are the best way to go. However..the bulbs in some of these units are terrible! I've seen countless failures in these TVs. The bulbs are only rated for 2000 hours, if you get 4000..you're just lucky!
Thanks for the link. Very interesting stuff, from owning both Plasma and LCD..neither is perfect too me. But I'm not one to do a lot of splitting hairs with this stuff. I enjoy watching movies on a regular basis with my PC.
I did notice on my buddies Sharp(same panel as mine) some trailing effects with a certain BR movie. I however haven't seen this trailing effect with my BRs. He uses a standalone Blu ray player and I use my PC of course.
It seems as some videos are more prone to this than others..like live sporting events. I don't know..this technology is still being perfected ..even on the camera end. I give it a few more years and the flat panels will exceed CRT in those aspects that they may come in short now.
I have a CRT 36" Sony Wega that I tried to watch a standard DVD on recently. You couldn't give me a CRT now! lol
I hadn't used my Wega in almost 2 years after crossing over to flat panels. It is still sitting unused as I type this.
I went from a Sony Wega to a Panasonic 50" plasma. I alsways liked my Wega, with its enhanced magnetic squeeze, it made DVDs look great. However, since I got the plasma, I would never go back, either. I have the 50" Panasonic, and a 37" LG LCD I got for the kids Wii, and I like the plasma much better for DVDs, even though the LG still looks very good.
I still think plasma has the edge in picture quality, no matter which LCD you compare them to. I also agree that typical in store sets are never set up properly. Get them home and set them up to some calibrated standard, and they all look much better.
Yeah..I agree the Plasma's as a whole do have an edge in the cinematic department.
The LCDs are just a little more friendly when it comes to other task..like gaming or everyday computer monitor use.My next flat panel will be a Panasonic Plasma..it will only be for Movie and normal TV watching though. I see a 60" in my future ..maybe next year! ;-)
