How to display video simultaneously on two monitors without a computer?

Question

Video

There is a task - there are two monitors (not yet purchased, you need to understand which ones to take) and a video. How can I get these monitors to show this video at the same time in a closed loop, without using a computer?
UPD: The video will be from a flash drive, the question is how to simultaneously submit it to both screens

Answer 1

Without a computer - almost nothing :)
