This video demo shows how easy it is to make any VGA projector wireless. With the plug-and-play Wireless Video Presentation System from Black Box, a roomful of Wi-Fi laptop users... more/see it nowcan access a VGA projector wirelessly from hundreds of feet away—eliminating the need to swap cables at the projector when you want to switch presenters. The video guides you step by step through a typical conference room setup, including how to connect to the Wireless VPS and how to configure it through its user-friendly admin screen. collapse
To ensure the best video resolution, it’s important to match your video extension device with a compatible grade of cable. Some multimedia extenders are not designed to transmit video across... more/see it nowcable that’s higher than CAT5. In fact, with these extenders, the higher-grade cable may actually degrade video.
The problem is with the cable twists of CAT5e and CAT6 cables. To reduce signaling crosstalk, these higher-grade cables have tighter twists—and more of them—than CAT5 cable does. For this reason, the wire distance that an electrical signal has to travel is different for each pair. This doesn’t normally cause a problem with data, but if you’re sending higher-resolution analog video signals across long cables, you may see color separation caused by the video signals arriving at different times.
To avoid this, you could use only the lower-grade cable with the extenders. But what if you already have CAT5e or higher cable installed in your building, or you simply want the latest and greatest copper wiring? Order an extender receiver that features built-in skew compensation so it can work properly with higher cable grades at longer distances. collapse
