I had a new TV I wanted to hook to the computer, but I still wanted to use my monitor. By hooking this up, I was able to accomplish this. I can use my monitor 99% of the time, but if I want to watch something I recorded in Media Center, I flip the switch and it's a done deal! Works excellent, with no hit to picture quality that I can see!
Stay away from this one if you can. On input 'A', the display was ghosted, but otherwise fully functional. When switching to 'B', one of the pins did not seem to contact properly the display was missing colors and had a heavy blue wash. I'll have to take it apart and re-solder the pins to see if it'll work properly.
Stay away from this one. It looks, feels and functions like a cheap switch. You're getting what you pay for and in this case, it's not much.
All I had to do is plug in the cables and I have 2 computers at my finger tips. I use a blue tooth mouse and keyboard so, it was very easy. I don't have to use two keyboards or mouses. It's simply wonderful. I'm a telecommuter and need work and personal kept seperated. Love it.....Oh I needed another cable for this. 1 goes from the box to the monitor and 2 go from each desk top computer to the box
