I haven’t seen evidence of such panels. The high-res-with-touch panels I’ve seen, have touch on a separate connector and use high-res 40-pin eDP pinout. Please do share if you found something (would love to put it here!), but as far as I’m aware, such panels don’t exist. So, 2 types of 40-pin eDP panel connectors, not 3.
Yes, the Framework eDP cable uses the high-res eDP pinout.
The FrmW eDP cable only carries high-speed data lanes to the 40-pin high-res panel connector, and doesn’t carry touch signals. It does carry all the lanes available - that is, 4 of them.
On the mainboard-side custom connector, there’s provisions for both high-res eDP (4-lane) and touch. The touch signals on the mainboard-side connector aren’t used in anything we’re aware of, except research from someone on Discord that I don’t currently have link for.
BTW, the mainboard-side connector happens to also be 40-pin! Confusing! I suggest we just call it the “mainboard-side connector”, omitting pin amount to avoid mixing it up with panel-side 40-pin connectors.
Yes on the former, idk what you mean on the latter.
Yes, for some, it seems that 5V is used as touch voltage. Regardless, this is the smallest of our problems at the moment, and is easy to work around.
Sure, find a 40-pin high-res (touch-less or with touch on different connector) panel and plug it in. Perhaps, check if the pinout’s matching, but it’s standardized enough that it ought to.
