Calibration and Viewing Angles

Most monitor vendors today will advertise the color accuracy of their displays to some degree on marketing material, and the ASUS PB328Q is no different, quoting 100% sRGB. More often than not we find that the out of box experience with monitors can be quite poor, favoring heavy blues and oversaturated colors rather than actual color accuracy.

The ASUS PB328Q does a very good job with its out of the box, uncalibrated testing result, by simply selecting the sRGB preset. The grays are balanced well and it looks like reds and greens are a bit oversaturated but overall the experience without going through the hassle of self calibration or even downloading our calibration file, is pretty good for this VA panel.

Going through a full calibration gives us a nearly perfect sRGB representation, pulling back the greens and yellows a bit to balance it out. This is what you expect from a monitor that you can use for professional development and content creation. 

This diagram shows the result in the typical XxY fashion – the color triangle represents the before-calibration result while the dashed line represents (close to) the final result.

Calibration Profile Download

The Windows color profile management interface is a bit of a mess, with the need to select and enable a profile in multiple layers of the interface. The best guide for loading and enabling a profile can be found over at TFTCentral. We used the following tools to generate our own calibration profile:

Our calibration profile was created using the lowest calibration speed in a dimly lit room. Here are the required settings if you wish to use our profile:

  • User mode 1
  • Brightness: 21
  • Red: 42
  • Green: 39
  • Blue: 50
  • Profile download: (HERE)

The above profile was created specifically for a color temperature target of 6500K at a luminance of 120 cd/m2 (nit). Gamma 2.2. Remember that the only way to get a correct calibration on your specific panel is by using a colorimeter on that very panel. The above settings and profile will only get *your* display to a perfect calibration if it has the exact same properties as our test sample. A perfect match is unlikely, but this should get you far closer to calibrated than just running with defaults.

Viewing Angles

VA-based monitors tend to sit between TN and IPS screens in terms of viewing angles though we have seen that creep closer and closer to IPS in recently iterations. 

Front

Bottom

Top

Side

The straight on view is nearly perfect which is good news for professionals, developers and gamers alike. Views from the bottom, top and side angle are less impressive with the creep in of the reddish hue indicative of color shifting. There is no noticeable inversion of colors, which you would likely see in any TN screen, so the VA-screen inclusion for this product from ASUS definitely pays off.
