Pixel latency is another term used for the refresh rate (mhz).
Color rendering is the amount of colors that the LCD can display without being effected by an external source of light.
There are a few main things that you should take into consideration when looking at an LCD...
· Response Time
· Maximum Resolution
· Viewing Angle
· Contrast Ratio
· Surface Type
Personally - I have never bought a monitor (CRT/LCD) from the store prior to researching the specifications.
You should definatly look into a ViewSonic. You will be more than happy with the quality, as well as the features.
Hope this helped!
