HannStar HW223DP

As opposed to the previous model, the HW223DP is based on a 22.0” matrix.

The specs seem to differ a lot, but it’s not really so. The difference in the specified response time – 8 milliseconds against 5 milliseconds – can hardly be perceived with the eye because neither matrix has Response Time Compensation. They are going to be equally slow in practice. The viewing angles, very modest in the HW223DP model, are measured using the more honest method with a contrast ratio reduction to 5:1. If measured by a reduction to 10:1, the numbers would grow up to 160 degrees just like in the HG216D specs.

The HW223DP looks nice thanks to the rounded-off outline of the case and the overall compactness. Strangely enough, this monitor is almost 1 centimeter narrower than the HG216D (509mm against 518mm) despite the larger matrix.

The stand allows to adjust the tilt of the screen only. It can be replaced with a standard VESA mount if you want.

The monitor is equipped with analog and digital video inputs. The latter is a standard DVI connector, and the box contains all the cables necessary. There is a line audio input for the integrated speaker near the video inputs.

Besides that, the monitor has an integrated 4-port USB hub whose ports are located on the right side of the case.

The control buttons are at the bottom edge of the case, somewhat to the right, but their labels are on the front panel making it easy to find the button you need. As opposed to the HG216D, the power indicator has reasonable size and intensity and is not distracting at work. Quick access is provided to the sound volume setting and to the auto-adjustment feature.

By default, the monitor has 100% brightness and 70% contrast. I selected 50% brightness and 53% contrast to achieve a 100nit white. The monitor regulates its brightness by means of backlight modulation at a frequency of 240Hz.

Color gradients are reproduced without banding at any settings, but dark halftones are indistinguishable at 30% or lower contrast. If the contrast setting is higher than 70%, the monitor loses light halftones.
