pixialization with comcast

12-31-2007, 12:26 AM
Has anyone had a problem with comcast recently as far as pixilization. I get it bad when im watching digital channels such as HBO or Cinemax. I have had three repair guys come out and look at it and 2 of them said that it was my LCD which is a samsung..I called Samsung and they came out and said that it wasnt the T.V. which i figured because I only get pixilization when i weatch cable and not on other sources such as my 360 and Upconvert DVD player. My personal take on it is that they have overmaxed there bandwith because we just recently added 5 or 6 HD channels and I think the digital and analog channels are suffering because of it. Does anybody have a similar problem....I live in Fort Wayne, IN

There can be any number of issues that cause pixelization. The most likely culprit, in my experience, is the wiring in our own homes. In some cases, the wiring is too low-quality. In other cases, it is simply split too many times, or with bad splitters, to deliver a strong enough signal. In still other case (my most recent experience) my cable signal was too strong, and I had to remove a signal amplifier to get rid of pixelization. (Keep in mind that at one point, the signal was too weak, requiring installation of the amp -- that just shows how this can change over time.)

Bandwidth utilization doesn't typically cause pixelization. Instead, excess bandwidth utilization is typically noticed in the form of graininess.

You definitely need your cable company to come back out to fix the problem.

Up in South Bend I have never had that problem with HBO or Cinemax. Beautiful picture on both. Must be your line.

Switch out all the cable and the splitters. It is true that too strong a signal can be a problem too.
