Yep! Just about any driver board that can convert between different input formats will also have an OSD.
I’m kinda surprised people have so many questions about this. I dug up the emails. I paid $176 incl shipping/tax to zjtechhk for a B156ZAN03.4 panel, eDP cable, and a MST9U11Q1 driver board (which has DP, HDMI, and USBC inputs, eDP output, and a ribbon cable to a PCB with 4 buttons to control the OSD)
It was an awesome deal at the time, but I’m pretty sure all these components are obsolete by now.
But does it have a terrible menu system, that takes 1 button press to change the color of gaming LEDs but 10 button presses to change the input? If not, it will never compete with commercial monitors.
It’s for factory workers that assemble laptops. Despite the label, it’s perfectly ok to touch it. There’s a flex PCB behind the label that drives the backlight and converts the eDP signal to pixels. It’s normally protected by the laptop bezel so it’s somewhat fragile. If you bend it, you’ll break traces on the PCB or pop components off.
You are! My first laptop ~15 years ago had a super thin (1mm?) fluorescent tube below the panel where the flex PCB would be. It used thousands of volts to start the backlight.
My panel (and anything from the last decade) uses LED backlights so I would not expect anything above 60V.
My current daily driver is the XB273K (27” 4K 120hz)
