The monitor’s color gamut is larger than sRGB in greens but smaller in blues and reds.
The average uniformity of white brightness is 4.9% with a maximum deflection of 14.7%. For black, the numbers are 6.4% and 18.4%, respectively, which is an acceptable result.
The gamma curves are normal at the default settings except that the contrast is rather too high for the blue curve as is indicated by the characteristic bend of the curve in the top right of the diagram.
It’s better at the reduced contrast: the curves are all shaped well and go near each other, although lower than the theoretical curve for gamma 2.2.
The monitor does not have Response Time Compensation. Its matrix is not fast having an average response time of 12.2 milliseconds (GtG) with a maximum of about 20 milliseconds.
Although the color temperature measurements produced good results formally, I didn’t like the image in the 6500K mode as it had a clear greenish hue.
The color gamut diagram is built for the 6500K mode to show you the answer. The point of white (marked with a white circle) is shifted upwards, towards greens, relative to where it must be (marked with a cross). The numbers in the table above are reasonable because it virtually makes no sense to measure the color temperature with such a shift of the white point. The color on the screen is not white while the term color temperature refers to white only.
There was no greenish hue in the other modes but most users are not going to be satisfied with them as they produce an image that is too cold or too warm. So, the only way to make the HG216D reproduce colors normally is to set it up manually, achieving a correct reproduction of white.
The brightness of white and the contrast ratio are typical for a modern TN matrix. This technology has progressed recently in this respect. A contrast ratio of 300:1 is finally a thing of the past.
The monitor doesn’t have factory-set modes with preset values of brightness and contrast.
- Low price
- Some flaws in the design of the front panel
- Slow matrix
- Sloppy color temperature setup
- No factory-set image modes
- Low quality of interpolation at non-native resolutions
- No HDMI-DVI cable in the kit
- Text-based applications (documents, spreadsheets, Internet)
- Movies and games that don’t require a fast matrix
