LPA works fine without the monitor attached. Got to use it with hdmi just fine. (glad I averted it being completely dead. It really just took learning how to use the supplied PSU)
Does anyone else have this issue with a monitor attached? Do you just mainly use DC power vs USB-C?

Theoretically speaking, Alpha and Delta's Intel CPU/SoC eDP port can support up to 3840x2160 @ 60Hz resolution (note this is interface spec only, not actual real life, say gaming, performance.)
Naturally, one has to select the right type of eDP glass (at least, 30pin, eDP, etc. etc.) to achieve such high resolution (4K UHD.)
BTW, at 17.3 inch, the 4K resolution, in its finest details will be a challenge for bare eyes.

hello,
how can I resolve the compatibility issue you mentioned below. I have the old generation 7 "LCD and I want to use it.
What can be the solution?
"MIPI display designed for LattePanda 1st genernation is not compatible with eDP display connector designed on Alpha and Delta. This compatibility issue is caused by different CPU architecture and positioning."

B173RTN02.2
I found ribbons on aliexpress. You need 30 pin, .5mm pitch, with the correct gold connector on one end (IPEX, I believe), and the bare plated ribbons on the other. I bought one “a” and one “b”. One version has the top side ribbon exposed, other version has the bottom side exposed (relative to the metal connector). So one type reverses the connection order. Not sure which is which and don’t know which one I actually used to get it working, but see the picture and you will know which you need to find. They both came in one package weeks after I ordered them, once again study the pics to get your bearings.
One thing that I do know now, is that pin 30 marked on the LCD must connect to the side of the connector on the latte panda that says “touch”. (See pics again)
So yeah it’s working, no bios changes or drivers etc, happy. My screen does have a few dead pixels curiously in the shape of letters “dB”, I’ll give that to the fact that yeah it’s China, these discount screens didn’t make prime time, so the factory owners brother sells them on Amazon. No big deal for me.
Type-B (the picture on the right), at least, for my 11" LCD eDP display.
P.S., a nice trick is when ordering the eDP display, ask the selling to get the flex cable for you and ship at the same time. You might get a fairly good discount on the cable/shipping on that.
