Technically regarded the signal for the computer monitor over the Beamer is rerouted, so that both at the monitor and over the Beamer the same picture is spent. Many models have however additionally also entrances for similar sources e.g. video recorders. The dissolution of diagram of the Beamers is limited both by the abilities of the diagram subsystem of the heading for computer and the Beamers. At present available Beamer supports however ith D R. at least the SVGA-standard (800x600 pixels).
A substantial criterion for the usable barness of Beamern with larger projection distances and/or surfaces is the brightness of the lamp. Beamer, which are used in larger conference rooms, should carry out between 1.000 and 4.000 ANSI lumens. The reaching of such and higher light achievement sodium mostly becomes-steaming TLA dung lamps uses.

- LCD light gates
