In reply to my own post on page 109:
The display arrived yesterday and I spent the day completing my sensor panel. Here is the result.
Short review of the display:
The mounting for the display is not yet optimal and will be replaced by something more stable. There is also the option of mounting the display on the back with a 75x75 VESA bracket.
About the display itself:
Bought at AliExpress, NVArcher Store, this is the 14 inch CNC Black version. Shipping to Germany took about 3 weeks. The quality of the display is absolutely outstanding, the front is reflective, it's even FreeSync and HDR compatible and supposedly capable of 144Hz according to the OSD. However, I wouldn't necessarily use it for gaming because of the rather unusual format. Power supply via USB-C works without problems, I use it via an HDMI->DP adapter on my PC. According to the OSD, the second USB-C port on the display is also able to receive an image signal, but I haven't tested this yet due to the lack of a DP->USB-C cable.
I can recommend it after about 2 days of use, the long-term test is still to come.
