REVIEW: Hyundai W220S Part 10

As usual, interpolation side effects are less pronounced on the W220S in moving pictures. The resolution 1.280 x 800 stands out negatively because of the blurry overall impression.

Overall, however, the Hyundai W220S delivers a good result in terms of interpolation. The degree of sharpness is at a high level almost without exception. In addition, the user is offered two options for improved interpolation with the justified and 1:1 display. This is especially useful for older games without widescreen support. Alternatively, the scaling can be carried out by the graphics card for the small number of unsupported resolutions. However, modern cards often have problems with this option, which is why interpolation via the monitor would be preferable.

Responsiveness

The following section should only demonstrate the general gaming characteristics of the monitor. We will examine the 3D effect in a later section. The manufacturer indicates a response time of 5 milliseconds for the W220S. With this theoretical value, the model does not match the manufacturer’s details for many rival models. However, the suitability of a monitor for gaming is also dependent on factors such as the controversial input lag and a possible corona effect. All factors depend on the implementation of the overdrive function, which can be switched on and off via the OSD.

During our test, the activation and deactivation of the overdrive function demonstrated no change with regard to the response time, input lag or corona effect: the controls are always very direct, no corona effects arise and only the slow response time is expressed through above average streak formation, which is not only due to the fact that the W220S is a Hold Type display.

The image quality is not always convincing in games. Because of the poor grey resolution, colour gaps arise in dark scenes in particular. The night sky in the shooting game "Crysis" is one example.

Input lag

Because of the low lag in Windows usage and direct controls in games, we would guess that the input lag is low. However, our detailed test procedure should reveal any lag, however low.

For the measurement, a new tool called SMTT is used, which uses hardware-expedited image output via Direct3D to display several highly precise counters at the same time and minimise other lags which may affect the measurement.

To this end, the image from the Hyundai W220S was cloned on a tube monitor and photographed. The most recent values displayed can thus be compared with each other in order to assess the extent of the lag.
