So I received my Hyperpixel 4.0 yesterday. I have tried several different avenues to approach this, however, it doesn’t seem that my display operates correctly.
I have set up an account with DAKboard, so I can display calendar entries on this HyperPixel. I follow all the steps to the letter, and when it reboots, it is a black screen. When I touch the screen, on occasion, it will show the desktop, only on the side I touch. Seems to happen more on the side of the GPIO pins. When I say it shows the desktop, I say this sparingly. In that, it is extremely compressed and doesn’t have anything resembling proper scaling. Then this “ghost” of the desktop disappears.
I have flashed, Jessie, Stretch, and Buster images at it. Tried different Rpi boards, a 3, 3B+. Not trying one of my 4s. They are occupied.
