The Samsung TC241W has a maximum contrast ratio of 1000:1. That's 100% less contrast ratio than a 20000000:1 flatpanel monitor, which is the most common contrast ratio. The worst contrast ratio of all PC monitors of a comparable type and age to the TC241W is Mega Contrast and the best is 100000000:1.
Alternative flatpanel monitors that have a 1000:1 dynamic contrast ratio currently available which you might want to look at include a cheaper PC monitor such as the Samsung SMT-2232 (£358.00) or you might consider a higher rated PC monitor such as the Eizo ColorEdge CS230 (£426.99), or the Samsung S27A850.
If you would prefer a PC monitor with a higher contrast ratio then you might also want to consider the LG 32WL30 (£521.80) (500000:1 and cheaper) or the MultiSync EA244 (£306.00) (25000:1 and higher rated), or the MultiSync EA294WMi (£459.57) (25000:1 and higher rated) both from NEC.
