If u r worried with TV frame think about Fresnel Lens. Enlarge monitor image, it is effectively disappear monitor FRAME for multi monitor setup by using 2 or 3 lenses. Before i buy my actual tv i was also thinking in a set of 3 monitors combined with fresnel lens. About Fresnel i have a doubt in one thing, i don't know if this will reduce the quality of the image.
