How to Use a Dual Video Monitor VGA Y-Splitter Cable
A Video Graphics Array (VGA) Y-splitter cable enables simultaneous display of the same image from a TV screen to another monitor, from a laptop to a PC monitor, or from one PC to two separate monitors within a short distance. In the latter cases, however, you may need a better video card to support a higher resolution. Its personal benefits are to effectively create two video screens for home-viewing pleasure and to create wider, dual screens while working in the home office. Commercial purposes include setting up training modules and displays during trade shows.

Turn off the power of both your TV and the other monitor. Make sure both sets are unplugged from their outlets for safety reasons.

Attach one end of the Y-splitter cable to the back of your TV screen. Use the main or single end of the cable, which is color-coded to match the port at the back of the TV screen.

Attach the other end of the Y-splitter cable to the back of the second monitor. Use one of the two remaining free ends, which are also color-coded to match the port on your second monitor.

4
Plug your TV in first and then the other monitor, and switch on the power buttons of both sets.
-
5
Observe if there are identical images on both screens. Expect the image quality of either or both the TV and monitor to be a little more rough and shadowy than usual. Remember that the signal is being halved toward each output. The image quality should remain sharp when you use only one monitor at a time.
