I'm coming from an IPS monitor myself, huge difference

This is definitely recommended if you're looking for the ultimate upgrade to your gaming experience. I used to have a standard 1440p IPS panel, but the difference with an OLED monitor is truly night and day. It's like my graphics settings have been boosted from HIGH to ULTRA in-game, purely because of the display. I personally never imagined it would make such a difference.
Is it a must-have? Absolutely not. If you're looking to upgrade, I'd prioritize your PC components first. But if you already have a system that can handle 1440p gaming perfectly, then this is definitely recommended.

I'm very pleased with the product. Unfortunately, only one DisplayPort cable is included, but multiple connections are possible. Nice, thin bezel, and a sturdy platform. It can be rotated/adjusted in multiple ways, so it's very versatile.
