I have a Sony SXRD kds-50a 2000 (green screen, therefore looking for a new TV) that does very well in my room facing four large windows and three more on the side. The only Sony TV I can find that seems to be a matte screen is the KDL60W850B. Do you think this will work in our 20x20 room? Seems like all the 4k models are glossy screens. Am I on the right track? I have been researching this for approximately two months, and I must say you have the BEST info that I can find (that applies to me) on the web. Thank you for this great site!
