Show images on a monitor using Arduino via Wifi Consider a computer monitor hanging on a wall. Next to it is an Arduino Uno with a wifi. Is it possible to create something like this? Using wifi it should be possible to send data (images) to Arduino. This will be output to a monitor, like an image gallery. Images can be any type (videos included). 

Is it possible? Where does one start?

Thank you.
I have somewhere in my stash a shield that enables an Arduino to overlay graphics on the screen. But it is kinda crude and low-res. What you're trying to achieve is definitely not for Arduino, it is way underpowered.

You'd better look into doing this with something like a Raspberry Pi.
