Samsung sync master monitors were well known for bad capacitors, if you have a esr capacitor meter you can check in circuit, if not look for dome shape at the top of the capacitor, a dead give away it is open, also check for poor solder connections in the power supply inverter board area.
The fault sounds like a invert problem, the inverter supplies high voltage to the CCFL lamp which provides the backlight. If you see a dim image when you look at the LCD screen at a sharp angle then this confirms this diagnostics.

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
Sounds like the Backlight balance sensor circuit is shutting down the inverter supply. A weak bulb can cause this or a malfunctioning sensor circuit can cause it too. Best method to troubleshoot is to substitute good bulbs; if it still shuts down, look for a pair of small electrolytic caps on the inverter board near the bulb sockets. They may be weak.

Sometimes this is due to graphics cards, but most of the time it is due to drivers. If it does not happen when you are using your PC for other things the problem probably just lies with the graphic card, driver, and this particular game or any game similar. Drivers are the most notorious! Check your requirements on the game for graphics cards recommendations! Let me know!
