It can´t be true that u can´t play the game on the monitor. You haven´t even explained what exactly the problem is. Do you have a black screen or what? I have the syncmaster 740bf (17") at home and can play every game I want. You have the same monitor, but 19" response time 2 ms (gray to gray). Push the auto button check the connection cable turn the monitor on. Try all the buttons on the front side especially the button left from the auto button.
