Quoted from the section on this:

“Glossy screen finishes reflect less light overall than other screen finishes. Because there is less light reflected back, the blacks in the picture remain darker than they do on TVs with a semi-gloss screen. Contrast is one of the most important elements of picture quality, and so it is safe to say that, overall, glossy screen finishes offer the best picture quality of any screen finish.

This is also why matte screens are no longer around. The perceivable depth of blacks isn’t as great with matte, and so in that regard, the picture looked worse than it does with semi-gloss or glossy screens.”

I have a very old matte finish monitor, and after spending a week with a new TV with a glossy screen, the reflections were maddening along with poor black uniformity. The blacks on this monitor look superior to that of the glossy screen TV. As someone who has used tons of matte screens and a fair number of glossy, this sounds like bunk to me and more a reverse engineered explanation why the fact we don’t have matte screens now is “actually better” when it really isn’t.

Same thing for why bigger TVs are considered better than smaller - it’s beyond frustrating that manufacturers seem to think those who want a quality screen just want bigger and bigger all the time. I’m in a small room and already using pretty large screens for the room size, I literally cannot fit the sizes which have the best pictures and qualities to them so I’m left with compromises even “money is no object”. The TV industry is extremely frustrating in their march for “progress” in this manner.
