TFT screens on the market that it's quite difficult to make a recommendation. I use two 19" TFTs on a daily basis - one is an AOC and the other an LG.
On balance I prefer the LG, although to be honest there's not that much difference between them in terms of display quality. The only real way to make judgments about monitors is to see them working - go to computer stores and see what they have on display. One person's idea of a good display isn't always the same as another's.
