Audioplus if the finish of the monitor is glossy you might get good results but if it's not and does have some texture or grain in it I'm affraid you'll end up with a glossy patch compared with the rest of the plastic. Maybe just very limited fine grit sanding will be enough to lessen the problem but it will depend on how the plastic surface is iluminated. If you use a plastic care product be certain that it's OK for the plastic material you're dealing with. This will diminish the gloss increase but before doing anything try in an area of the TV that is not that visible like behind the set. Hope this helps
