I'm wanting to buy a BenQ G2420HDBL but I'm unsure what the contrast ratio's, and whether it is dynamic or not, means in laymans terms. Am I only gonna get 1,000:1 generally and 5,000,000:1 on certain things? Or am I better getting the BenQ G2420HDB which has standard 40,000 contrast ratio? I will mainly be using it for web design.

Any advice / explanation welcome .... thanks in advance
 
lols @ 5000000:1
Most of these figures are utter nonsense. You "may" get the quoted figure using the dynamic range, but in all honesty most people turn off dynamic contrast and/or dynamic brightness it just really messes things up imo.

Most monitors use rgb colour space, and there is only so black you can go, i.e. black. Good contrast means being able to distinguish between colour scale in the rgb space not how black the screen can go. As an example my monitor quotes a static range of 1000:1 in reality its actually about 870:1. And my monitor (nec ea231wmi) shows subjectively black as black but I doubt it is actually black according to the rbg scale. When you turn on dynamic contrast what tends to happen is a the colors look compressesed. So if you have a dark scene everyting will look dark, if you have a bright scene everything just looks overly bright and washed out. Ideally what you want os the monitor to be able to keep the dark scenes dark and the bright scense bright with the full colour range in between.

If your really concerned about constrast then you need to pick up a pva or ips model and be willing to take the extra cost.

The difference between the LED and non-LED version of those Benq's are pretty negligible. Power consumption will be the only difference that is noticeable, picture quality wise they will be very similar.

Just get the cheapest one imo.
