I got pretty lucky! These models (among others from competitors) are known to have issues such as dead pixels, Backlight Bleed, and bad quality control in general, but even after getting a refurbished model? Pure perfection.
Came with the smallest amount of backlight bleed in the right hand corner, and that was it. No dead pixels, no links or panels problems, and Overclocked just fine to 165 hz.
At a price of $550 instead of the usual $800+ these days for a new one, it's a steal and a great monitor to boot if you have the rig capable of it.
