The largest leftover issue is finding a setup with enough outputs. | If your source is a PC, that PC's ability to deal with multiple monitors (which has been around for a ''long'' while now) will do all the splitting up at the video card stage. | ||

capture cards do not come cheap enough for this to make much difference with a dedicated splitter | |||
