I want to use either an ipad or sony tablet as a larger 2nd display. The problem being the st16 outputs through hdmi which is fine if you are flying in your lounge and want to connect to the tv! I have trawled through goodle search but i am struggeling to find anyway to provide a wired connection. A dedicated 10" battery powered HD field monitor with hdmi input is around £300 which seems a daft option when i have two tablets avalible! Anyone with any ideas?
