When it comes to planning out the video signal distribution of your event, there are numerous choices. All of them have their strengths and weaknesses. Here is our first post to help you on your video distribution journey!
Let’s Stop with – VGA (Video Graphics Array)
VGA was created by IBM in 1987 and was the gold standard of hotel AV for many years. Carrying the Red, Blue, Green, Horizontal Sync, and Vertical Sync signals, it could support many resolutions.
The 15 pins that made up the connector were fragile and would often fall off or lose a solder joint causing the image to lose a Red, Green, Blue, or drop it altogether. It was limited in range and would have to have an amplifier in line to help reach a display with any integrity over 100′ (sometimes less).
Although the resolutions could reach HD quality the frequent discussions about AV terms like “ghosting and “horizontal and vertical crawl However, the advantage was that there was no (Extended Display Identification Data) to worry about It didn’t require a “handshake” pass the signal.
The connector also had screws to secure it ensuring it did not disconnect during use. Many reminisce about how easy it used to be to plug something in and have it function even if it did not work perfectly.
