want to use 3 monitors

[Robert Oaks 0]

Usually we install a PC with GEO 600 card, and 2 monitors. We install a 19" monitor in the lobby of banks, and a 15" by the computer as a set-up monitor. The 19" is on 24/7. When the 19" monitor is in the range of 100' from the computer we use a video splitter which allows the monitor to be up to several hundred feet. If it is a short distance, we just use an A-B video switch. We have an upcoming application to use (2) 19" monitors that will be on 24/7, along with the 15" set-up monitor (only on for purpose of set-up and viewing recorded events). One 19" will be about 100' and the other 19" only 25'. How would you handle this? Thank you very much for your input. Robert
