Of the several VA panels I tried, the 32GK850F showed the least amount of pixel latency artifacts. Most noticeable is when you pan the camera in dark scenes, usually manifesting as a purple trail behind dark objects. It can also happen in brighter scenes involving small changes in pixel colour, like clouds.
Due to overdrive on freesync monitors being fixed, the lower the refresh rate, the worse the overshoot. Truth be told, it didn't bother me! But, I tried three of them and all had faults so I give up! I still recommend it though for anyone looking for 32" as the first two actually had good panels with the best black uniformity I've seen on a monitor!
Thanks very much for your reply, really appreciated.
