Who are you asking? There are a few Omnibots (5403 and 2000) with screens installed on them.

i am asking DJ sures. he made this video on how to do it.

The same question was asked by another member yesterday and has been answered.

The screen is an automotive monitor, measure the omnibot for accurate size but I believe Matt used a 6" in Omnimc.

It does not connect to the EZ-B. DJ had it hooked up to an ipod which basically played back a video. If you install an onboard PC which can run ARC you could use ARC commands to start videos etc. however the specifics will vary depending on what your intention is for the screen.
