Step 2 - Locate the IOGear 2 port video splitter
Step 3 – Disconnect the VGA cable that is connected to the projector/smartboard.
Step 4 – Connect the your device cable to the projector cable with the coupler end.
Step 5 – Connect other end of the VGA cable to your device (laptop or iPad).

From time to time we are asked to move around into different teaching space, but in order to make a lesson be consistent, we need to use the same resources. This includes using LCD projectors. If we are teaching most of our lessons in a dedicated space that has an LCD, that is great, however, when we go into a teaching space and need a projector, we can either bring one on a rolling cart or learn to connect to the existing system.
The existing systems are most likely to consist of a stationary classroom desktop computer that is probably connected to a smart board and an overhead LCD projector. In this blog entry, I will only address connecting to the overhead projector.
The classroom computers are most often comprised of a tower (or flat desk console), a keyboard, a mouse and a monitor (screen). In our district they a still using the old analog VGA cables to connect the tower to the monitor. When it is connected to the overhead LCD projector, the VGA cable goes to a 2 port video splitter. The 2 port splitter has one input and two outputs, so it sends one signal to the monitor and one signal to the LCD projector. Those signals are mirrored signals meaning they supposed to show the same thing on the projector as the computer screen. Note: the resolution is going to be higher on the desktop monitor than it is on the smartboard or on the computer screen because of the lower resolution limitations of the LCD projectors.
