The best deal on a cheap HDMI monitor I've been able to find is actually a TV. It has HDMI, VGA, RCA type analog video inputs. It has a DVD drive tucked in behind the screen, you can plug a USB memory stick or SD card into it to view pictures or play MP3s. And it runs on 12 volts: comes with a wall wart and I think also a cord with a cigarette lighter plug, but it has a standard 2.1 or 2.5 mm coaxial power input jack. Try to find a 12 volt HDMI monitor otherwise and they're expensive. I bought it to use with my DSLR for focusing so it at least had to run on a battery pack and be portable. I've used it, not extensively yet, connected to a Pi, with the HDMI input. Then I tried connecting it to a 6 meter ground plane antenna in the attic and discovered a TV station showing every episode of all 5 Star Trek series, so right now it gets used as a TV. The only problem I've had is that after dropping it a dozen times or so on a concrete floor the mute button on the remote is sluggish. I bought the 13 inch, but the same electronics are also used with bigger displays. Looks like they all use 1333x768 resolution. The EDID does work correctly with a Pi, you can use it without a config.txt file. A menu, reachable by remote, switches between the inputs. I bought a 13 inch for $140 but Walmart lists a few at $125 now. They're made up to at least 32 inch. https://www.axessusa.com/product-category/televisions/television-dvd-combo I have a tvd1801-13, I see there's also a tvd1803, don't know anything about that.

It was much worse than just being carefull. This was on a medium Have you considered a touch screen? https://www.raspberrypi.org/products/raspberry-pi-touch-display/ That's smallish at 7 inches but one-piece computer-monitor combos are all the rage on alibaba. A capacitive keyboard doesn't need to be much more than 2 spirals for each "key" etched as printed circuit traces. When you touch it the capacitance at that key changes. That can be mounted behind something like a flat sheet of glass and still adjusted to work. Whatever gets on the surface you just wipe off. The glass could be Pyrex like some stove tops. It takes at least a propane-oxygen flame to get hot enough to melt Pyrex, almost white hot. Probably a lot of reinventing the wheel to bring all that out to a USB plug unless you can find something surplus. -- Credit is the root of all evil. - AB1JX
