I've just remembered the other way to figure out the maximum supported resolution, count the number of pins on the eDP connector. 30 pins is two lanes, 40 is four. Since you need four for UHD and it looks like we have 30 pins on the Pinebook Pro there's no UHD panel support.
Indeed from the picture posted above your post I count 32 pins on the connector labeled "EDP":

But:
2.7 Gbps per eDP lane (as per RK3399 datasheet) means that 30-pin eDP (2 lanes) is only enough for FullHD.
QHD needs 4 lanes at 2.7 Gbps or 2 lanes at 5.4 Gbps (HBR2).
UHD needs 4 lanes at 5.4 Gbps (HBR2) or 2 lanes at 8.1 Gbps (HBR3).

Grr, so this means FullHD is the maximum, unless final design changes to 40-pin eDP connector, or it is somehow possible to operate the RK3399 eDP at more than 2.7 Gbps per lane. And the folks at the FOSDEM booth talked nonsense.
