You can activate the HDMI port on your ProScan TV to display video and picture in the highest possible resolution. HDMI, or high definition multimedia interface, is a connection standard that is supported by the electronics industry to deliver full HD content between a source and a display. The dual capabilities of the cable allow you to clear up the tangle of wires behind your home theater system and make connections in just a minute or two.
Turn off the ProScan TV and the video source.
Plug one end of the HDMI cable into the "HDMI OUT" port on the rear of your set-top box, DVD or Blu-ray player.
Insert the other end of the HDMI cable into the "HDMI IN" port on the input panel of the ProScan TV. Turn on the TV and the video source.
Press the "Input" or "TV/Video" button on the ProScan TV's remote until the image from the source appears on the screen.
