What I was asking about was the contrast ratio as opposed to the response time.
I have 2 AGM 19" widescreen that have a response time of 4 ms and a contrast ratio of 500:1.
I was just asking ( and was surpised by such high contrast ratio of 1400:1 that the LGM had) was what different contrast ratios do or look like and how relevant they are to a business user (mostly 2D charts, no gaming) like me if I buy additional monitors.
here is the missing point.
lg uses the dynamic contrast ratio which gets contrast at 2000:1 or even i see 2500:1 contrast ratio from monitors from lg.
however the true contrast of thesescreens is 600:1 or less.
