Office work / Web Design profile

Below you can see the results from the accuracy color checker with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange etc. The results are without and with the Office work / Web Design profile.

We’ve created the profile at 140 cd/m2, optimal white point (D65, 6500K) and sRGB gamma mode.

Gaming and Movie Nights profile

We’ve also measured how well the display is able to reproduce really dark parts of an image. It’s essential when watching movies or playing games. The left side of the image represents the display with stock settings while the right one with our custom profile for gaming and multimedia. On the horizontal axis, you will find the grayscale and on the vertical axis the luminance of the display. The display offers good visibility in dark areas of an image but it’s further improved by installing our profile.

We illustrate the first five levels of the gray (1%-5% white), right after black level, using the five boxes on the image below. Keep in mind that whether you can distinguish them or not strongly depends on the settings of your current display, the calibration, the viewing angle and the surrounding light conditions.

Health-Guard

Pulse Width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable by the human eye. In these light impulses the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our specialized article on PWM.

Our equipment was able to detect pulsations on LG LP156WHU-TPG1 across all brightness levels but at extremely high frequency (40 kHz). This means that the display may have an impact on users with extra sensitive eyes, although it’s quite unlikely.

The Health-Guard profile eliminates the PWM.

With our Health-Guard profile installed, you can benefit from reduced blue light emissions. You can see the levels of emitted blue light on the spectral power distribution (SDP).
