Yes DisplayPort MST hubs exist such as: https://www.tripplite.com/2-port-displayport-1.2-dvi-multi-stream-transport-mst-hub-1920-1080-1080p~B156002DVIV2 Even tripple adapters: https://www.startech.com/ca/AV/Displayport-Converters/Triple-Head-DisplayPort-Multi-Monitor-MST-Hub~MSTDP123DP I suspect that one needs active adapters to convert DP to VGA/DVI/HDMI, while a single DP+ port on the motherboard can use passive adapters instead. Most boards seem to have DP+ ports these days, although I am sure exceptions exist. > I just need HDMI to DVI converters for some rather old 1080p monitors that > are still working perfectly fine.

Seems the ITX board selection for AMD is rather crappy so far. Quite a few choices with better ports for intel it seems. -- Len Sorensen --- Talk Mailing List [email protected] https://gtalug.org/mailman/listinfo/talk
