Apple M9178LL/A vs ViewSonic VG2021M tft monitor shopping review
Apple M9178LL/A have larger screen (23") than ViewSonic VG2021M (20"). With its declared 1920x1200 maximum resolution Apple M9178LL/A monitor beats ViewSonic VG2021M with its 1400x1050. You shall not have ghost feeling when scrolling on ViewSonic VG2021M due to its pixel response time of 8ms, but we cannot say the same for Apple M9178LL/A since pixel response time is 16ms. Since VG2021M has luminance 300cd/m2 it can produce much brighter picture than M9178LL/A which has luminance 270cd/m2. Both TFT monitors have poor contrast (VG2021M has 500:1 and M9178LL/A has 400:1). Horizontal angle is 170º on both and therefore you might feel unconfortable watching movies . Vertical viewing angle is bad on both monitors (170º at Apple M9178LL/A and 155º at ViewSonic VG2021M) for watching movies. If you want to be able to connect your monitor to older computers, Apple M9178LL/A isn't good choice due to lack of VGA input. DVI input which these monitors have allows you to use with new video cards. More Information
