hell yeah, got displayport alt mode over usb-c working on rk3588 pocket reform with mainboard 2.0!in the end it was a DP lane polarity issue: USB3 allows lane polarity swap for better PCB routing, but DP doesn't. tricky when you need to reuse the same lanes for both.

but wait... does that mean MNT Pocket Reform can have 3 displays now (1 DP, 1 HDMI, 1 internal)? yes, yes it can!

@mntmn Bare aluminum case looks interesting to me. Any plans to release it as purchase along the mainboard 2.0?

@mntmnUSB-C hubs with multiple display outputs usually use MST, maybe one of those would be easier to get than an MST-supporting display?@ignaloidas

@mntmnThat is great news, congratulations! 🙌What are the odds this would work with the i.MX8MPlus too?

@hanno that would only be possible with a modified mezzanine (carrier card) for the imx8mplus, because hdmi/dp are on the same lines and are normally routed to hdmi out on the mainboard

@wolf480pl@mstdn.io @mntmn@mastodon.social yeah, my thoughts on usage are the sameThough it seems like rk3588 can't support MST, while the (lower-end) RK3576 can https://lwn.net/Articles/1031560/

@ignaloidas @wolf480pl yeah i also remember this as a newer feature. also not sure how useful it would be for 2 lanes

@mntmnIf I'm reading the table here https://en.wikipedia.org/wiki/DisplayPort#Refresh_frequency_limits_for_common_resolutionscorrectly ( it's for 4 lanes so divide fps by 2, then by 60 to see how many monitors fit)with 2 lanes and HBR3 one should be able to get 2x 1440p60Hz, right?@ignaloidas
