LCD Motion Blur versus Pixalation?

by mbeoletto / January 23, 2008 3:52 AM PST

I recently purchased the Sony 52W3000 for a great price. I am very happy with the picture quality, the only concern I have is that when watching HD content from my Cable HD Box (Cox Communications), I have noticed some severe pixaltion during fast scenes, in particular, on HBO HD in scenes like the chase scenes in King Kong and football scenes in We Are Marshall.

The kicker is: I own King Kong on HD-DVD and when I watch these scenes via my Toshiba HD-DVD player I do not witness this pixalation, thus I have to believe it has more to do with the content source and noise or compression artifacts, cable vs HD DVD player, than the refresh rate of the television.

I have been half tempted to exchange my t.v. for one with the 120HZ refresh rate. The store reps tell you that the 120HZ will almost eliminate the pixalation issue. But I'm not so sure, I'm having a hard time understanding if motion blur is the same thing as pixalation and from what I read on CNET it doesn't sound like it is. I think motion blur is more ghosting and thus I'll get the same pixalition from Cable HD with a 120Hz set that I get with my current t.v. with the only difference being I spent more money.

Can anyone please help shed some light?

motion blur and pixelation (noise) are two different things. Changing TVs for this issue will not help. The pixelation is from the compression of the signal from your cable. The reason you don't see it on the HD-DVD is because it is a pristine source (or should be depending on the quality of the master and how it was transferred).

You will get them from time to time on cable, can't be helped.

If you can afford to get the XBR4, I would though. It will not fix this issue but it is better TV in my opinion. The 120hz will make a world of a difference in other areas.

Thank you sir. I wish I could get the XBR 4 but unfortunately because of its glass perimeter it will not fit my townhouse's allocated t.v. location and I chose to go with the 52 inch over
the 46" XBR4. I thought in the long term I'd be happier with the bigger pitcure.

Like I said, my only gripe has been the pixelation. In couldn't be
happier with the W3000's HD DVD and XBox 360 performance.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
