[t520 + nv 4200m]
Been trying to track down where my migraines at work have been coming from and have finally realized that this laptop is the primary culprit.
It appears that the main screen is very blurry and is crushing my eye sockets. No idea what the deal is.
I've recently tried updating to the latest stable NVidia driver release and haven't seen any difference. What on earth could this h/w be doing to make the screen just blurry enough to give me serious migraines during normal use.
