Anyone know a lot about eDP cable pinouts?

A display I'm looking at to upgrade a laptop to, model NV156FHM-N4B, has "H-sync" (H-Sync for active pen) at pin 24 according to the datasheet. I assume this is for G-Sync support but I'm not sure, but it would be nice to know what it is and if it's necessary.

 

I'm choosing between display upgrades for a laptop and really want this specific one for its high contrast ratio and color gamut, but the one problem is that my stock display doesn't use pin 24 on the 30-pin EDP connector, and after examining the stock eDP cable there is indeed no wiring for that pin. Maybe my laptop's firmware supports H-sync on that pin but probably not. It's an HP-15bs234wm.

 

So, if all other necessary data/power/ground pins are compatible, am I safe to at least try this display out and expect it to work?
