|Figure 1. The display showing a message on my work bench.|
The wall mount I built is just a 1100x200 mm wooden shelf attached to the wall with three brackets. The display hangs from the shelf with 4 M3 screws. The heads of the screws are captive in the mounting slot on the top of the display. I first attached the shelf to the wall and then slid the display onto the hanging M3 screws. After everything was fixed, I drilled a hole through the wall for the power cable.
|Figure 2. The screws can move in the mounting slot of the display so that the display can be slid from side to side.|
Of course not everything went quite to plan. The screw holes for two of the brackets originally hit some concrete inside the wall, and while I could have drilled the holes with my hammer drill, I opted to move the brackets instead. This of course left some slightly ugly extra holes in both the shelf as well as the wall. I'll probably fix these later, as I still have to take the display down to paint it white. Also the shelf is a quarter of a degree crooked, which is visible as it is so close to the ceiling.

Anyway, I declare this a success. Now to write some code to have it display useful stuff.
