Macbook brightness on external monitor

My Dad recently purchased a Samsung 570 27 inch monitor to aid viewing text when using his current model Macbook Pro. The output is through his Thunderbolt port. He is finding the image quite dark compared to his laptop screen and can't seem to find any info on brightening it at the monitor end. Are there any options within the Macbook to brighten the output? Suggestions appreciated.

You're in one of the high speed response modes, faster or fastest (brightness control is disabled in these modes). Under the Game section of the menu.
It would appear the issue is not with your Mac, but rather with the 'games setting' on the monitor.
