Signal Splitters for Videowall-type Setups?
TwoHeadsAin'tGoodEnough asks: "For our current contract, my company needs to find video splitters which don't just replicate the same signal across all monitors. Googling isn't helping too much, because thousands of people are selling video splitters, but they're all the wrong kind. We need to split a signal onto 4 displays. (Each display is going to be a 52" plasma screen, *drool*). It doesn't matter whether we are splitting analog vga output or dvi output, so long as it works. Any suggestions?" These type of setups are commonly called "videowalls", and there is a library out there called VWLib that can be used to manipulate such systems. Some videowalls are custom affairs, but I'm sure there are commercial entites out there that build complete setups. Have any of you tried to put something like this together? If so, what were your experiences? Update: 03/12 9:15pm EDT by C :After digging thru the Slashdot Archives, this story was found that might also shed some light on the subject.
The way I have done videowalls in the past is to use the zoom feature on the plasma screens (most expensive screen have this feature). All you need do is zoom the 4 screens so they are all showing a different quarter of the output screen then you use a standard video splitter to split up the output from 1 computer to the four screens...
