Apply's displays are pretty much all glossy. PC monitor manufacturers seem content on allowing Apple to have this de-facto monopoly over glossy screens; further adding to the irony is that everywhere you look online about this topic there are hundreds of people asking "where can I find a monitor that works on PC which looks as good as an iMac" -- and unfortunately modern iMacs can no longer double as displays for PC's.
I think anyone who thinks matte is better should put a matte protector over their phone for a month, then rip it off, and see if they really still prefer matte. Chances are, the moment they rip it off they'll realize the clarity they've been missing out on. Then, consider that it makes even LESS sense to have a matte desktop gaming/entertainment monitor than a matte phone, because a phone could be used anywhere but a desktop monitor would be positioned such that it's guaranteed to never have glare!
I believe there are maybe 1 or 2 glossy displays for PC's out there but unfortunately they're extremely expensive, don't come in 1440p, and don't have 144hz refresh rate.
I have a monitor which is great in every way except the matte coating. It seems like it would be so easy for them to just make literally the exact same monitor, but glossy style, and rake in all the money from the high-demand, zero-supply situation.
