Well first off the PS5 is 1440p capable now. The LG monitor is one of the best in the business of gaming monitors. It goes to 144 Hz so it will support the 120 Hz of the PS5 easily. Note you may need to go into monitor settings to enable the Hz FPS high modes. But overall if you want to use it with PS5 it seems easy. 1440p with 120 Hz. No idea if will support VRR though.
