Hi I'm looking to buy a new monitor for my computer. I'm currently using an nokia 500xa. It's got a contrast ratio of 300:1 and 30ms response. It's pretty damn old and I think it's time for an upgrade. I just have a few questions about monitors. 1) What the average contrast ratio of a monitor? 2) Should I get a monitor that has dynamic contrast ratio or static contrast ratio? 3) Is dynamic contrast ratio any good? 4) Is this monitor good: http://www.jr.com/JRProductPage.process?Product=4158793? Any help would be appreciated.
