Tech Tips March 2012
For decades, VGA (Video Graphics Array) ports have been essential for connecting laptops to presentation systems. In the switch from analog to digital video signals, laptop computers are making the transition from VGA to HDMI (High-Definition Multimedia Interface). Soon, consumer devises will no longer come equip with a VGA port, but instead, will come only with the HDMI port.
Why HDMI? HDMI is a compact audio/video interface for transmitting uncompressed digital data. HDMI transmits a better quality video signal, offers High Definition audio, a more secure content protection, and enhanced communication between the video source and the display source than does VGA.
What does this mean for me? (A) Because the HDMI output is digital video and VGA is analog video, the switch will require a converter. Unfortunately, a VGA to HDMI adaptor cable does not exist, so a converter will become a necessity. As you might imagine, most schools and conference rooms that are outfitted for analog video will need to be converted to digital video. (B) If you have copyright material embedded in a PowerPoint presentation, the content will not play when the computer output is switched to HDMI.
What’s happening to VGA? By 2014, new models of consumer devices will no longer produce High Definition video with an analog video connection. (For Blu-ray players it was January 1, 2011.) New computers having the capability to play HD video will only get HDMI output connectors.
The switch is referred to as the Analog Sunset.
