after two month of use , I feel I do not make a good choice . horizontal movement be not smooth at all . it hurt the eye , especially when watch sport program and action movie . after buy , I find that it be a 24 frame per second projector instead of a 60fp one . Eco mode must be set every time you turn the projector on . the good thing of the pro 8200 you read from the manufacturer be true and plenty to consider , but the extremely annoying horizontal juddering or shake effect must also be consider .
