ok...i got this hair brained idea to put 8 or 10 screens onto ONE 46 LCD HD tv. I found a video splitter that will only do quads. Is it even possible to put 10 computers onto one screen? I figured someone here may know the answer and point me in the right direction. The 4 screen splitter is 4k. The sales person couldnt tell me if I could daisy chain another splitter and control that with one keyboard. If it's not available, then why not?
