For some reason, the sidebars on my 40XBR4 have suddenly changed from black to grey when watching a 4:3 SD channel. The output from my TWC cable box is 16:9 with 4:3 in letterbox. It seems that the change of the sidebars to grey has also been accompanied by a decrease in resolution. Any idea why this has changed and what can be done to get the black sidebars back. I much prefer the black background when watching these channels and am a little concerned that there may be some burn in with the grey.
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?
