ViewSonic Optiquest Q9b-2 vs ViewSonic VA912b tft monitor review
Screen on both monitor is 19" large.
Both of compared TFT monitors : ViewSonic Optiquest Q9b-2 and ViewSonic VA912b have the same maximum screen resolution (1280x1024).
These TFT monitors have decent response times of their pixels (8 ms).
Only ViewSonic Optiquest Q9b-2 is able to produce very bright picture (300 cd/m2 luminance), ViewSonic VA912b has brightness 250 cd/m2.
Optiquest Q9b-2 has good contrast ratio (700:1) but that is not the case with VA912b (500:1).
These LCD monitors are poor for watching tv programs or movies since they haven't decent horizontal viewing angles (VA912b has 160º and Optiquest Q9b-2 has 150º).
Verical angle is 160º on VA912b and 135 ºon Optiquest Q9b-2 and those values makes them unsuitable for watching movies.
DVI input which has ViewSonic VA912b is its adventage.
