Conference room projector only one VGA interface, and the conference table requires 4 VGA desktop socket, how to connect?
For example: A, B, C three A computer, A computer access display screen, then B B computer access display screen, and then display the C C access to the computer screen, then pull out of C B after the computer display screen, A display, B pulled out of the computer screen, if the C access C computer display the picture, always automatically switch the signal the last road access.
Recommend using products: automatic 4 in 1 out VGA switcherImplementation function: after the first access, that is: the last access to the VGA signal is automatically detected and preferred to switch the output (this type of product can also be used to switch the remote control).
Advantage: don't need people who need to switch on the plug connection table projection of your computer, it will automatically switch out, if the 4 are connected, second people still want to re projection, so second people can be VGA line from the table and plug pulled out, then, second people is the last way, will automatically switch out.
