- "Marty Junior stood in the next room, calling out numbers at a big screen. The screen responded by showing six different pictures for six different television programs. The thing Marty Junior was watching was some sort of giant, multi-channel video screen — a screen that hung crooked on the wall. Jennifer had to push back an urge to rush out there and try to straighten the picture out."
- —From Back to the Future Part II by Craig Shaw Gardner (quote, page 77)
A multi-channel video screen was a large wall mounted flat-screen television capable of displaying at least six channels at once.
The video screen also had the capability to show The Art Channel across all the separate screens that comprised the larger screen. Through the AT&T system, video telephone calls and video conferences could be held on the screen as well.
Marty McFly, Jr. was able to watch six channels at once — namely "channels 18, 24, 63, 109, 87 and The Weather Channel" — and then was disappointed when he could only watch two channels at once on his video glasses.
The 300+ Channel Universe was available on this video screen.
- The multi-channel video screen envisioned for 2015 proved to be an accurate prediction on the part of Bob Gale and Robert Zemeckis. as in the real 2010s including 2015 wall mounted wide screen televisions are common. In March 2009, six and a half years before the setting for Part II, the "DirecTV" television service provided a feature called "Game Mix" which would allow subscribers to watch four channels for a few weeks while the NCAA college basketball tournament was in progress. "See up to four games simultaneously on a single screen. No need to switch from station to station" was the tagline. Although DirecTV hired Christopher Lloyd to reprise his role as Doc, and recreated Hill Valley, for a commercial, there has been no Back to the Future tie-in in conjunction with "Game Mix". On October 27th, 2009, Cablevision also launched "QuickView" channel mosaic which allowed cable subscribers to watch nine channels at once of either sports, news, or cartoons on a single screen. The audio of whichever specific channel box is highlighted is activated for the viewer, and it is easy to tune to specific channels via the Select button. Viewers can tune back to the mosaic view through the "last" or "B" buttons on the remote.
- The video screen was remarkable for for its futuristic view of interactive media.
