I've mentioned a Hitachi 65G500 65" rear projection TV in a previous question about surround sound. I've noticed very large pixelization, but only with shades of red. To describe further, when there is a scene in entirely red lighting, there isn't a smooth separation from one shade of red to another. What I see are large red squares of different colors, kind of like you are looking at the scene through a red stained glass window. It is like the TV is trying to make smooth separation, but it doesn't have enough colors to do it.
This happens on digital cable channels that are coming through at 480p along with analog channels. Since it is only with red (I've never seen it with any other colors), it is hard to always catch and I haven't seen it on any HDTV 1080i programs. I haven't tried it with a DVD player yet, but I'm going to seek out scenes soon.
My question: is this something normally expected with big screen TVs (red-only pixelization), or is it a potential problem with my Hitachi. Is this expected or do I have a problem.
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?
