- There are two possible solutions here; the clean one, the recommended one,
- the one that will produce absolutely the ultimate in performance, build
- strong bodies twelve ways, and make you the envy of your one-monitor friends,
- is something called a "distribution amplifier," which takes a single input
- but provides 2 (or more) outputs. Several companies (Covid and Extron come
- to mind - check your local AV distributor, or the Thomas Register) come to
- mind. These things are available for up to and beyond 1280x1024 workstation
- display timing. (You'll need something like 100 MHz bandwidth *minimum* for
- an acceptable image at this resolution.)
-
- The quick-and-dirty kludge of a solution is to open up one of the monitors
- and remove the 75 ohm termination on all the video inputs (assuming that
- your monitor doesn't simply have a switch that lets you go from "75" to
- "HI Z" or something like that), and then connect to this monitor with BNC
- "T" connectors to allow you to connect a cable to the second monitor, which
- then goes at the end of the whole string. It works almost as well, but now
- you're stuck with either using two monitors all the time, or sticking an
- external terminating resistor on the "T" if you're not using the second unit.
