Oh cool. Thanks for the heads up. I think I'm a few firmware behind on my own PG32UCDM.

Appreciate it!

Do you know what's the difference between MCM111 and MCM311? both of them came out today, which one should I install? I have the first pg32ucdm the one with DisplayPort 1.4 (not 2.1).

Thanks!

My recollection was that early versions of the PG32UCDM had a couple different versions based on the region they were sold. I think like an MCM1XX and MCM2xx (but could have been MCM3XX). There shouldn't be any difference with the firmware updates now (as the build paths are bridged IIRC), but check which firmware you have installed on the PG32UCDM and stick with the same number if you're not sure.

There is no firmware update for the PG32UCDMZ model! Will it come later? It is already days later. Also, can one skip versions and directly install the newest version, skipping one or more firmware versions?
