The color gamut coincides with the standard sRGB color space in blues, smaller than it in reds and larger in greens. That’s quite an ordinary picture except that the triangle is shifted a little to the right, towards yellow.
The average and maximum brightness uniformity is 4.7% and 11.6%, respectively, for white. For black, the numbers are 8.0% and 20%. Although the uniformity of black seems to be high when expressed in numbers, the pictures above show you that the brighter areas are distributed on the screen in an ordinary way: an X-shaped pattern without strikingly different areas. The white brightness is quite uniform.
The gamma curves are acceptable at the default settings except that the blue curve has a too high contrast which is indicated by the characteristic bend of the curve in the top right of the diagram.
This drawback is lost when the contrast is reduced although the blue curve still goes higher than the red and green curves. Moreover, as I noted above, you shouldn’t reduce the contrast setting too much: if you set it below 30%, dark halftones will become indistinguishable from black.
The response time average is 12.5 milliseconds (GtG). So, notwithstanding the specs, this matrix is actually no different from the above-discussed HG216D. Of course, the HW223DP doesn’t have Response Time Compensation.
The Warm and Nature modes are set up neatly enough while the Cool and User modes (the latter at the default settings) have a big difference between the temperatures of white and gray. Well, if the monitor’s contrast is lowered to 50-60%, this drawback becomes insignificant: the color marked as white in the table above will be outside the available dynamic range.
The contrast ratio is rather high. The brightness is ordinary for this product class and doesn’t make it to the specified 300 nits.
The monitor lacks any modes with brightness/contrast presets.
Highs:
- Neat exterior design
- Low price
Lows:
- Slow matrix
- Problems with darks at a contrast of 30% and lower
- No factory-set image modes
- Non-uniform brightness of black
Recommended usage:
- Text-based applications (documents, spreadsheets, Internet)
- Movies and games that don’t require a fast matrix
