Brightness And Contrast Ratio  Touchscreen Computing: Gateway
ZX4931 And HP TouchSmart 310  Frankly, it isn't very meaningful
to compare the out-of-box performance of one monitor to another.
If you want to know what a monitor is capable of, you need to
normalize settings in the same way you benchmark two graphics
cards. That's what calibrating a monitor does; think of it as
benchmarking under controlled settings.  Once calibrated, HP's
TouchSmart 310 starts looking more impressive. While we cannot
maintain a 200 cd/m2 white luminance, we can calibrate the black
to a deeper tone, which results in a contrast ratio of over
1000:1. In comparison, Gateway's ZX4931 starts to falter as we
calibrate. In order to achieve a 6500 K white point and a 2.2
target gamma, we have to drop white luminance. The ZX4931 still
produces respectably dark blacks, but the drop in white
luminance results in a contrast ration of ~800:1.  React To This
