I have tried multiple monitor configurations for trading with mixed results. Each monitor gives off several degrees of heat which is cumulative as most rooms ventilation is fixed by the diameter and length of the ductwork. I am looking for a heat rating on monitors so that I could basically forecast my anticipated office temperature increase. This is a large trading office with two systems, one with a 24" and one with a 37". Have tried up to eight 19"'s but the result was too much heat and a sluggish response.
