Okay but it supports 5 monitors. 1 via HDMI and 4 via the Thunderport / DisplayPort Type-C outputs. I've got a Lenovo Thinkpad and I use a $15 Type C to DisplayPort adapter and it works fine at 4K @60Hz
The specs say it supports 6K @60Hz over the Type-C ports and 4K for the HDMI port
In general I agree with you, but I think that may be a limitation of Asashi right now. So if you want a display it may be your only choice for a desktop.
