Important Notes

The computer and both displays must use a common resolution

Splitting of the VGA signal can degrade the video appearance

Passive cable only duplicates (does not extend) the PC screen to a monitor

VGA cables (sold separately) are required

Audio is not supported over VGA, it must be transmitted separately

Specifications

Host Connector: VGA Male

Display Connectors: 2 x VGA Female

Customer Feedback

"Splitter works with 2 displays plugged in at the same time. If you only have one display plugged in with this splitter, the image will become distorted as the signal is intended to be split and passed through to two displays."

"The video works well, but the screws were too short. Not a deal breaker for high-quality video transmission, and it won't be in danger of becoming unplugged anyway...THIS ITEM was for displaying the same computer video output on two screens, both my monitor and my TV (which has VGA input, no HDMI).
To have my computer audio AND video wired to two different outputs in two different rooms, I needed the following:
This VGA splitter (1 male to 2 female) and
a 3.5 mini-stereo splitter (1 male to 2 female)
which gave me the inputs needed for my original PC audio and video cables AND I now have the additional audio and video connections needed to send those signals to my TV.
To get the a/v to my tv I also needed:
A 35ft VGA cable (which had an integrated 3.5 audio cable ) with all male connectors. It was run from the computer through the floor and under the house and up to the TV.
Add a 3.5 mini-stereo adapter (1 female to 2 RCA male plugs)
Plug the VGA into the TV, and insert the adapted RCA plugs into the TV...Ta-Dah!
Now (if you have your computer set for it) you have your TV showing exactly what is on your PC, and the volume can also be changed with the TV remote.

Additionally:

My computer has Windows Media Center, which can schedule and record like a Tivo if you have a TV tuner, so I bought a USB tuner (for the new ATSC HighDefinition TV signal). I added a great indoor antenna (actually a super small outdoor type Dtv2B 2-Bay Uhf Antenna) and now have all my local channels and a free 11-day viewing guide on my computer! Now, I can set up my fave series to be recorded ahead of time, and watch them when I want.
The last thing I bought was a remote with a USB infrared receiver that is "WMC" compatible (Windows Media Center) and now I can choose what show to record and which one to watch, all from the comfort of my Laz-y-Girl recliner! The next room is close with an open floor plan, and the line of sight for the infrared receiver for the remote 25 ft. away works just fine. Ahh!"

"STC provided me with this great Y splitter monitor cord that allowed me to take my computer and send it to 2 different monitors at the same time. At least that was the plan. The tech that my job offers me is a bit older than the ideas I had in my head. I purchased this cable splitter without checking the devices I had. They could not do the task I wanted at work. Now, it worked at home, but that was not where I needed it. They thankfully were willing to accept the cord back with no damage to it and very slight use... I hope to work with them again."
