Why 1440p appears to have been abandoned is beyond me!
I have a PG279Q which I do love but it isn't without its issues and does have a single dead pixel albeit luckily in a really hard to see spot on the edge.
Gimme 1440p, quality HDR, IPS/OLED/MicroLED and High refresh rates and I'll be a happy man
Not sure if I would want OLED for gaming (super dark games will be impossible to play from experience) but certainly I do want 1440p 144hz IPS with 1ms response time.
I already have that but just a TN. It shows too next to an IPS monitor.
