I am a (semiproud) new owner of the Gemini, and I am considering buying the Planet's HDMI adapter. However, I have a crucial question - what resolutions does the HDMI output support? Basically from the hardware point of view; by reading various discussion I am starting to suspect that this is fixed at the LCD resolution of 2160×1080. Since there are monitors (and especially projectors) that support only certain resolutions (or up to a certain resolution), is there a way of changing it? Has anyone here successfully connected Gemini HDMI in lower than native resolution mode? I am mostly interested in Android and Linux, but I am not sure if the current Debian supports HDMI at all.

Failing that, I would go rather for {chrome,mira}cast instead of the cable, but the same question remains, I am not sure if it is possible to change the resolution here.

I've has bad luck getting the PC adaptor to work with different screen. I eventually went with a DisplayLink adapter and it works with any screen I plug it into (even with an HDMI adapter attached). That doesn't really answer your question, but it might be an avenue worth exploring.
