what do you mean the best resolution to "reduce yes train high or low"
the benq monitors seem to be the leader in the technology.
this page is a year old but it lists the flicker free monitors available at the time and the ones in blue are links to reviews on those models.
it is kind of a matter of preference. the higher the resolution the sharper the image will be. But things will also tend to be smaller and maybe more difficult to read.
what i think may be the best thing is to use the higher resolution but then resize your desktop to make everything larger under the personalization options. that way you kind of get the best of both worlds
