We just switched phone carriers and bought 4 new Samsung phones - and were given Four 32" 720P Samsung HDTVs for doing so. They are Samsung UN32J4000 32-Inch 720p LED TVs that go for about $200 each on Amazon. I was planning on selling them but the wife asked a once-in-a-lifetime question in reply - can we use them to build a video wall?

 

She has a wall that she can't decide how to decorate in the office. She thinks it would be awesome to turn it into a video wall if we could do it on the cheap - when are we ever going to have 4 TVs just laying around again? Any thoughts from the group? Would a 2x2 video wall be worth it?

You are one lucky man!

Keith Mallett. yes - for a multitude of reasons, but she is definitely a "keeper".

Hang on to her. Those are hard to come by!

 

On the cheap... What kind of price range are you looking at? For photos, I assume...

I setup a video wall a few years ago for a t-mobile store, but those TVs were designed for that use. They had a setting where you could specify the number of TVs in the grid and where each TV was located then they all daisy chained together.

 

I'm guessing yours don't do that though, so your best bet would probably be USB->VGA adapters connected to a cheap laptop or mini tower. The refresh rate on USB2.0 devices isn't that great in my experience, but probably good enough for stills.

I was thinking maybe something that could display a rotation of pictures using a RasPi2 but could also stream HD video from our Plex server.

Hi Pete, what phone carried was offering this deal?

[G+_Pete Warner]

AT&T deal when purchased through Best Buy.

It depends on what you consider cheap. But if you're thinking in the RasPi arena, It is possible, and here are several sites showing it: http://lmgtfy.com/?q=synchronized+raspberriPi+for+multiples+screen+video

The best part of that LMGTFY was the typos Google corrected lol.

It looks like there is a Pi Wall project (http://www.piwall.co.uk/information/10-create-your-own-gpl-movie-piwall), but that requires a Pi for each TV and another Pi or laptop for control, plus a network switch.

 

A Pi Zero may be an option, but the adapters and accessories would add up (USB OTG + Ethernet, MICRO HDMI to HDMI)...

 

Sounds like a fun project though.
