New monitor question

I have a NV 460 GTX (1 MB) GPU, and am currently running FSX on a 5 year old Samsung 16:9 monitor. (My earlier monitor was a Sony reflective / glossy 4:3 screen that had the issues of the reflective screen from light behind the monitor, but had very bright and vivid colors). The Samsung was a matt (non-reflective) screen, which solved the reflectivity issue but the colors were much darker and less vivid, and not easily fixed by the monitor settings (which seemed to introduce noise and artifacts when I tried to overcome the dullness of the image).So, now it's time to do it again. Hopefully more successfully! I sit about 6 feet from the monitor (I see posts in this sub-forum with recommended screen sizes for various distances from the viewer). What I'm not sure in what I should be looking for are factors such as Anti Glare, Resolution, Refresh Rate and Response Time, and what else there may be that I might need to look for.Thanks, Bruce.
