They did, at least for some of the presentations. qole's presentation, for instance, was run from a Nokia-owned tablet in which the kernel and other software had been enhanced to support a USB-to-VGA adapter.* Where that wasn't feasible, a document camera was used. I was underwhelmed by the quality of that unit though.


* Were Nokia to able to finally release these modifications, a USB-to-VGA adapter plus a scan converter would be another answer to the thread starter. However, the need for that scan converter would make this solution only slightly less ridiculous than the document camera one.

I must say though, it's a poor data projector that doesn't support at least RGB in this day and age, and while I understand trade-offs must have been made for size, that PICO projector doesn't even accept Y/C. That's a shame.
