I made a adapter board which can drive the back light and pinout a full size DP port.
The backlight driver is running in constant current mode and dimming is done through a digital potentiometer.
The input is 5V compatible, but preferred to have ~ 2A to provide enough power for back light LEDs.
The screen from ebay is far from perfect, next time I will try to order to oversea seller, at least they have a reasonable price to begin with.
The Lcd is pretty capable, it compatible to various non-native resolutions, like 800x600, 1024x768 etc. However, I can tell Intel integrated GPU has better compatibility in non-native resolutions than AMD integrated GPU.
The casing is card board, the laser cut acrylic is too expensive to me ....
Anyway, here are the pics.
