Desplay imagine from Arduino to pc monitor

Due to a change in collaborators I have been left to try and work out how to set up an artwork using an Arduino with little prior knowledge and was wondering if anyone knew of any forums or videos that cover this issue:

I am trying to project an image on USB connected to a USB host sheild on an Arduino uno to a computer monitor via the mini desplay port (using a hdmi adaptatior).

I have to use this set up as my work tours for a number of months without my supervision and my previous partner suggested the Arduino as a method of instantly desplaying an image the moment power is switched on.

Hope this makes as much sense as possible, any leads valued immensely

I would use a Raspberry pi. Far simpler and no additional components needed.
