Getting A Gauge

As with all monitor testing, we start off with our calibration process. While the Philips 239C4QHSB boasts a brightness of 250 cd/m2 and a dynamic contrast ratio of 20,000,000:1, we always prefer to measure these figures for ourselves to establish a better gauge of the capabilities of the device.

First up, the pertinent numbers which should give you a base line on what to expect from this particular Philips monitor when you plug it in.

Basic Measurements
White Luminescence 266.2 cd/m2
Black Luminescence 0.38 cd/m2
Static Contrast 700.6:1
Color Temperature 6300 K

These measurements were taken with the brightness set at the maximum level, standard out-of-the-box settings and all other enhancements and features turned off.


Calibration

Trying to get the monitor to the 120 cd/m2 brightness sweet spot with the help of our Spyder testing equipment, we found out that for properly calibrated picture, you should drop the brightness setting to 31 (out of a 100). The results of our calibration can be seen in the screenshot below.

Before calibration, the visuals of the monitor had a slightly green tinge to them. Calibration rectifies this problem to a great degree, but unfortunately it does not eliminate it completely.


Screen Uniformity

With the help of our Sypder test equipment, we were also able to determine the screen uniformity of the Philips monitor which can be seen in the graph below.
On average, the panel has a deviation of about 5 percent at 100% IRE which is not too shabby. If not for the Spyder calibrated report, when viewing regular content, we were unable to discern any serious uniformity discrepancies.

IRE is a unit of measurement for video signals. The numbers 100% denote the fact that the color ranges from black all the way to white. Using 100% IRE for screen uniformity allows us to gauge the performance of the screen across the entire spectrum of visible light.
