How can I get my MK808 mini Android PC to output to my TV?
Its the resolution setting. That or your tv/monitor doesn't support the default setting. I was switching mine to all the different sizes and switched it to one my monitor didn't support. Was a total pain to switch back as I flipped it to some off size. Just try every tv/monitor you can find until it comes up. I have noted on a few occasions, it doesn't seem like its booting up right away, I had to unplug and wait a minute, then retry.
