This is a good monitor:http://www.amazon.co.uk/BenQ-GL2450E-Widescreen-1920x1080-Brilliant/dp/B00AK5F6LI/ref=sr_1_3?s=computers&ie=UTF8&qid=1374794312&sr=1-3&keywords=BenQ+GL2450
60Hz refresh rate (so if you have vsync turned on you can play games at around 60FPS
5ms which is a good response time
good price
very good manufacturer (quality products)
nice and thin
native resolution is 1920x1080 so you can play games full 1080p
I have one and it is a really good monior to play games on (such as Borderlands 2, Half life etc)
I have used a monitor with a 2ms response time and I noticed NO difference.
