I know the lower the pitch the sharper the image, but how is it that monitors with higher ag pitches get better scores than monitors with lower pitches? for examples the iiyama Vision Master Pro 451 has a 25mm at center and a .27mm at corner but yet it get's a higher rating at more sites than the Mitsubishi Diamond Pro 920 which has a .24mm unified pitch, if I'm not mistaken, doesn't unified pitch mean that the screen is .24mm from center to corner? if so, how is it able to be rated lower than iiyama Vision Master Pro 451, what other factors can cause a monitor to have better overall image quality besides it's pitch and bandwidth?
