I currently have a 27" 1440p 180hz IPS gaming monitor as my primary screen and two 100hz monitor above as my work monitors. I'm considering going to a two monitor stack and trying to decide on a new gaming monitor and really leaning towards OLED 4k. I will likely stack the OLED 4k on bottom as my main and use the IPS monitor above it. Let me know what you think as far as 1440p vs 4k and OLED vs IPS and a recommended size. Both monitors will be used for gaming and work (I work from my house.)
