Am I the only one who believe Mac should just stick to 1080 resolution? it makes everything much better

You are just using it wrong

Kinda low rez, don't you think? I'm rather fond of the "retina" level displays... 27-inch (2560 x 1440) is kinda like a minimum for serious work for me. My 15.4-inch (2880 x 1800) laptop display is almost eyegasmic. A big reason I upgraded to the iPhone XS was because because of the 458 ppi Super Retina OLED screen. When I first saw one, my eyes did have 'a moment' :-D

Dots, must... have... more... dots!

I think you might just be only one
