If I was going to settle for a 19" TFT it would be a mid range one, something with 8ms response time and a contrast ratio of 800:1. Then with the money I would save I would put it on my Credit Card to save up for a better GFX Card… or maybe a new HDTV…
It’s really all relative to your situation. I my self am not made of money so will buy the mid range things on everything in my PC apart from Graphics cards where I normally buy the beast thing going. You have to ask your self a question. “Do I need the best 19” TFT monitor”, will you actually need all the features like 2ms and 1600:1.
If you’re made of money and have no problems, then yeh buy the best of everything. But since your going for a 19” monitor I suspect that is not the case so in my eyes you would be best to spend the money on a bigger monitor since I would take more pixels over better pixels for graphical work any day!
But then to answer your question, the LG looks to have the best specs out of all of them, although I have heard a few things about blank screens and gaming with there f-engine splash screen popping up. But that only seems to effect games not desktop work, that’s if it is an actual problem with that model of monitor. So I would choose the LG if I had to.
