Several years ago now, when the world and I first discovered home theater, I ran across a rather simple formula for calculating the best screen size (4:3 back then) given the distance to the audience, personalized to your taste. It had to do with determining the viewing angle you are comfortable with. Now, I can't find any such formulas.
Anyone out there run across a means of calculating the desired screen size (now WS) given distance to the couch?
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?
