These Adapters will allow transmitting signal between VGA video ports for distances up to 100' (approximately 33 meters) over CAT5, CAT5e, CAT6 Network cable (not included).

The distance and quality depends on length of the cable, and the resolution that you'd like to transmit. In our tests we were able to transmit 1280x1024 resolution over 50 ft. (17 meters) most of the time. Sometimes it goes up to 150 ft. (50 meters), that we cannot guarantee. This adapter will allow you to connect your personal computer, DVR, Media Center, or Game console VGA video port to TV, Projector, Remote Monitor with available VGA input for ultimate multimedia experience (gaming, slide shows, presentations, downloaded movies, etc.)

Product Feature:

This is an alternative solution for more expensive long range adapters - 400'-1000' over CAT5 
Compared to other VGA-over-something solutions, it's cheaper, compact, and does not require external power 
CAT5 is cheaper than a VGA cable (whether you're buying pre-made Ethernet cables or crimping your own off a roll) 
You can run Cat-5 easily through conduits (you may use shielded CAT5 for the best performance without conduit)

Useful Tips:

Make sure that the your connection works over regular VGA cable 
For the long runs try to avoid jack connections, for the best result use straight network CAT5 cable 
CAT5 cable may be affected by close proximity of fluorescent fixtures. If possible, keep it at least 2 feet (0.5 meters) away 
You CAN NOT use switch, router or hub to transmit video using these adapters 
CAT5 cable may be affected by close proximity of fluorescent fixtures. If possible, keep it at least 2 feet (0.5 meters) away 
You CAN use VGA switches, splitters, and amplifiers 
DO NOT use crossover network cable. Use either 568A, or 568B wiring on both ends 
If connecting to a TV with VGA PC Input, and there is the message “Unsupported PC Signal” check your manual for maximum or fixed resolution of your TV PC input. In most cases it is 1024x768. The other way to test the limits is to lower your PC video card resolution to 800x600, then gradually increase it. Some TV's and monitors require fixed resolution of the video card in order to display picture
