I've run out of screen real estate on my 10" tablet. I'd like to have a 15" or even 20" touchscreen display to mount on the wall.
Seems like Android tablets mostly max out at a 10" screen so I'm contemplating running a 15" portable monitor with a 4GB Raspberry Pi 4. I have no experience with Raspberry Pi's but I can definitely figure it out.
Wondering if anyone is doing anythign similar or has any other ideas for displays larger than a 10" Tablet? Is a 4GB Raspberry Pi 4 up to running an 15" 1080P screen, displaying a Sharptools dashboard with a few live camera feeds running?
I am using an Odroid C4 to drive a 15.6” Asus Zenscreen Touch. Display my Sharptools dashboard with it, although I don’t keep any live camera feeds on it. I wanted a large display with thin bezels, as well as something that could just be stuck on the wall flat without sticking out much from the wall. When it works, it’s awesome. It’s pretty finicky, though, so I have to unplug and replug the USB cables every now and then. Probably wouldn’t recommend the exact same setup unless you are willing to fiddle with it, but I haven’t found anything else that would work better yet. Interested to hear if anyone else has.
Getting sufficient power to these portable monitors, without draining their batteries, seems to be challenging. The Zenscreen requires a lot of juice. Have to use the right USB cables or else it won’t supply enough power.
Thanks JustinL, I could get sufficient power to the screen but definitely want something that's going to not be finicky. My tablet just works like 98% of the time but just need more screen real estate.
Thanks @snell for the suggestion too. That's a little more than I want to spend but a good option otherwise.
Hmm. Will have to maybe just test out a Raspberry Pi and mobile screen. Can always make use of the Pi somewhere else and return the mobile screen if the setup doesn't work I guess.
Not sure what your price point might be, but sometimes there are similar things for cheaper. On eBay for example I just searched on "android tablet digital signage" and found a very old (Android 4.4) 22" for ~$200 and a 32" for ~$400.
There were also a bunch of touchscreens that came up in a variety of sizes as well.
I was looking at those 22inches drawing tablet for a while. Some will work with just a pen while other with touch. Just waiting for my 17inch Iview AIO touchscreen to kick the bucket before I could upgrade . Yes, I am afraid of my wife.
I run a RPi3 connected to a 24" 1080 touchscreen monitor I bought on ebay for $75 (pre COVID). There are some guides on setting up the RPi as a kiosk on Chrome. From what I remember there is a setting to make the SD card read only so it doesn't get corrupted. I have mine on a ZigBee outlet and only turns on when scheduled to reduce power usage.
Dell p2314tt, I run 3 image streams on a hubitat dashboard from Blue Iris fine. The only issue I have encountered is there is no way to refresh the screen, but I could set up a reset button on the dashboard if I really wanted to.
