X-bit Labs took a look at a couple of 19" LCD displays: Acer AL1916W Asd,
NEC AccuSync LCD93VM,
Samsung SyncMaster 940N,
Samsung SyncMaster 940T and ViewSonic VA1903wb.
I guess you won’t be surprised to find that seven out of the eight monitors tested for this review are based on TN matrixes. This technology can boast neither good viewing angles nor a high contrast ratio in comparison with *VA or IPS matrixes, but it has one important advantage over them: TN matrixes are considerably cheaper to make. The manufacturers save not only on the type of the matrix, though. Almost all the models you’ll see in this review lack Response Time Compensation technology. The developers probably think that the response time is already high enough for office work. Some users may also take no notice of the slight variation in the specs. There seem to be little difference between monitors with a response time of 4 and 5 milliseconds, but it is actually very big, much bigger than 1 millisecond, as you’ll see again in this article.
Check it out over here. The reviewer says there wasn't a clear winner in the roundup.
