Edit: Actually it looks like resolution fixes the issue, in part. Playing Horizon 4@1080p and 75fps+ and I still get the ghosting. At 1440p it's gone.
Hey ASUS, please tell us something about this issue... will you fix it through a monitor firwmare update (if possible) or what?
New BIOS 308 for ASUS GL703GS...
Is the inverse ghosting less evident now (smaller dark trails) or is it just placebo?
