Are you just trying to freeze or replace the computer monitor? Motion should be able to track the computer monitor and replace the screen image or treat it to remove or reduce the filter.

I havent tried freezing it. I tried replacing the monitor with a black bezier but it isn't clean enough. my speaker moves ever so slightly and he is in front of the part of the monitor. not sure how to freeze it can you expand on that?

Motion or After Effects are the tools to do this. Neither are particularly easy to learn. Was the camera locked down on a tripod? I just meant finding a clean frame of the monitor, exporting it, bringing it into photoshop and cutting off the background and bringing that into fcp and editing it onto a higher video track. Adjusting the crop when the speaker moves in front of it will be the problem.

Any chance you could chroma key it? In your editor put the original footage on the bottom, then your clean frame of the monitor, then a duplicate layer of the original footage. Use a chroma keyer to isolate the speakers clothing. (Select the color of the clothes and invert the mask. I think you need to clock the triangle in the lower left of the effects panel and there's an option to invert the mask there.) That will overlay the presenter's clothes over the monitor and depending on how the shot is composed should do the trick.
I would definitely use a frame of the monitor on, though. If you use a black frame it could look unrealistic for a few reasons. First you will have light coming from the monitor, but it will be off. Things will be illuminated by a monitor that has been blacked out in editing. Also, unless you're willing to spend a while texturizing and doing lighting, it probably just won't blend in with the lighting in the room. You'll have a pitch black box where there should be reflections and highlights from other lights in the room.
