I saw some comments that extension cables did not work well. I wanted to use mine with my Xbox and no way am I going to sit that close . Using a long HDMi cable and this Amazon.com: Lemorele HDMI to USB C Adapter 4K@60HZ, HDMI to Type C Adapter, Compatible with Nreal Air, Rokid Air, Thunderbird AR, GRAWOOA, Switch Base, Steam Deck Base, PS4, PS5, Xbox : Electronics along with the supplied usbc works well. Maybe possible to use something similar to that to extend the usbc display?
Gonna go with this one. Lots of good reviews and some that say it works with rokid max, including the audio. Cant find the official ugreen one in stock or from any vendor I want to deal with. The elebase one had bad reviews saying it went bad after a while. Gofanco doesn't support hdmi audio. Theres also the siig one actually referred to by official Rokid reddit account. Would have preferred one with a male hdmi connector, but this one just seems to be a safe bet at this point.
Silly to have to do DP->HDMI->DP over USBC, but whatever... Amazes me that there is no simple DP->USBC adapters that it should just work. USBC uses DP signal for video...
