BenQ PG2401PT, 24-inch Color Accurate Monitor Review

Calibration With Palette Master

BenQ offers an alternative to the traditional OSD calibration in the form of a bundled app called Palette Master. It’s derived from X-Rite’s i1 Profiler software and offers adjustment of color gamut, grayscale, gamma, luminance, and screen uniformity. We installed it on our test system to give it a try. If you want to use the utility, you need an i1Pro, i1Pro 2, or an i1Display color meter.

After selecting Profile from the Home screen, the first set of options lets you specify the target color gamut and maximum luminance. If you select a custom gamut, you can enter the X and Y coordinates, along with the white point and gamma.

Next, you choose how precise your calibration will be by selecting the number of measurement patches. Small is 118 measurements. That's plenty in our opinion. If you select Large, over 400 patches are measured and you can expect to wait at least an hour for completion.

After positioning the meter, calibration is performed without further intervention. The result screen gives you a photo and a few color samples to make a before/after comparison. Once you're satisfied, save the profile to either the Calibration 1 or 2 memory slot. All of the data is stored in the PG2401PT’s firmware and an ICC profile is generated.

You can also create a screen uniformity look-up table. The grid size can be 3x3 or 5x5. By default, Palette Master measures 100-percent white (level 255) patterns, but you can use patterns at levels 16 or 128 if you want greater precision at lower brightness points.

We compared Palette Master’s results to our own OSD calibration and found them almost identical. The only discrepancy was a luminance reading about 7 cd/m2 higher than what we measured using CalMAN.

The biggest bummer tied to using the app is once you’ve set up a calibration memory, the Brightness control is locked out. If you want to change just the luminance value, you have to redo the entire process.
