Many members have said thanks for my post here so I thank you all humbly & understand that some more detailed info shall help others before & after buying LCD.
Before buying
Be aware! 2/4ms is grey to grey response time and not black to white which is
actual response time, don't fall prey to advertising gimmicks millisecond response time is all crap meant to please ignorant people so they can boast about their wide screens. Original response time is far over 16-18ms (black to white) & you see flares when you do a Direct X test, so beware advertising is meant to please us not serve our actual needs. Any fast response time u see less than 12ms is GTG not BTW so be aware that they had a bottleneck created all these years to achieve faster response times & suddenly overnight they are now offering fastest 2ms LCDs too.
I found later while color calibrating via spectrophotometer that these TN panels advertised as 8bit supposedly are actually 6bit plus 2bit interpolated & that's why they lack the gradients & can never pass that Grey gradient test mentioned below.
I suggest all the members here not to buy these wide screen monitors without actually testing them with your comp & the following software.
passmark monitor test (trial works for a month I guess)
PassMark Software - PC Benchmark and Test Software Passmark monitor test has R/G/B smooth gradient test & a grey gradient test which is where
most monitors fail. No banding should occur in any of the colors.
Another excellent utility which I used to benchmark my Lenove LCD was "Eizo monitor test" download it from this page.
PRAD | Eizo monitor test
With Eizo number 12 & 14th test are the most difficult test for LCD to pass my lenovo passes all of them perfectly hence I bought it.
Dead Pixel Tester
Dead pixel tester with display aids and illusions.

Pay Rs 500 more but ensure you test it with actual graphic cards as in India the dealers dont provide any return policy, once billed to you they wont take it back.
