@8666b6b1 Do you own a Pi? If so, those come with a number of complementary licenses for RealVNC IIRC. I've had good luck getting that up and running. 

 @Eric Zhang @8666b6b1 iPhones have had video out for ages, and most mid-range up Android phones do, too. I have occasionally used the lightning-hdmi adapter to show presentations when other hardware crapped out. 

 @aea3822c Nice! Getting a mixture of He-Man and Ghost vibes from that :D
