Sony s71r (i need help)

Hi, i just buyed a Sony s71r and is a great monitor it had better characteristics than the Hyundai Q17, but i tested games as Quake 3 and when im playing i can see how the image have afterglow, and also with serious sam 2 who have big maps i cant see it so easy but when i put in front of an object and move the mouse rapid i can see the image blurred. U can play games but the blurred can see when u move fast and turn fast in all games.

that happen also in the Hyundai ? please help me, i need to know it because i have buyed this panel thinking there wouldnt be problems with afterglow (that panel is 16 ms), and is a great monitor but if hyundai dont have afterglow as i said then i would have to change the sony.

Thanks all & sorry for my english.
