I'm a new member here, but have been reading some of the material for quite a while, and also am a ZisWorks x39 owner

On a 240Hz 1080p TN display with pixel overdrive enabled, I'm noticing what looks to be similar to "color-burn" or "dodge" of intense colors under strafing motion (e.g. image a poster on a wall, and strafing side to side while facing the wall - the poster looks normal at rest, and then appears to have a "color burn" applied to it under motion. It returns to it's normal (correct) appearance again at rest).
Has anyone else ever observed this kind of phenomenon? I'm going to do more tests later today and try to determine whether it's panel-related/panel-specific, or a generic artifact. And moreover, try to determine whether something we're doing in our engine is causing the issue, or whether again, it's a panel issue (or an optics issue - though I'm inclined to doubt that)...
This is vsync@240Hz with no dropped frames.
Thanks in advance for any feedback, particularly anyone who might have insight!

P.S. For those interested in high refresh displays (probably everyone here) - heads up that we're quietly developing a game/graphics engine which is already capable of driving 4K@1500Hz+ in complex interactive scenes today (unfortunately no displays actually support displaying this many pixels this fast, of course) - but hopefully one day we can help be a driving force in creation and adoption of actual 1KHz+ displays...
