The max resolution the MT will output is 1280X720 from my experience.
It will readily play back any 720p video (depending on the media player), but 1080p wouldn't be possible. I believe shmackshmack was simply stating that his monitor was 1080, not that the MT can output to that resolution.
To the OP-we've discussed this before on the forums, and the probability of getting HDMI-out is low. Again, as Whyzor, myself, and many others have said, this is due to the proprietary nature of Moto's drivers and their reluctance to release them (they're a company, they have to make money, blah blah blah...
)
I would say for now we're SOL. While I would like to think the current Google/Moto merger would change that, I doubt it. Be patient, as agentc13 said, and wait.
The devs are nothing short of miracle-workers (seriously, I don't care what any of you say), but everyone has limits on what can be done without a full team of people who are able (read: paid) to do this full-time. It's a difficult and lengthy process.
Just sit tight, and see what happens.
