REVIEW: Eizo S2242WH-GY Part 13

Interpolation

In the OSD of the Eizo S2242WH, three scaling settings are available: "Full screen", "Enlarged" and "Normal". The latter stands for one-to-one display, which means that even at non-native resolutions, the monitor can allocate a pixel per pixel – provided that scaling via graphics card is deactivated. Thus, the image display is always razor-sharp, but no longer uses the entire screen surface.

Native resolution of the Eizo S2242WH.

The next lower 16:10 resolution of 1.680 x 1.050 pixels is slightly stretched in height and width as soon as it is scaled to full screen. Scaling to "Normal" helps. Thus, the image displayed is as sharp as at the native resolution.

The Eizo S2242WH demonstrates interesting, not to say erroneous, behaviour for the resolution of 1.440 x 900 pixels. If this is to be displayed one-to-one, the image is still displayed as interpolated. Here, there is probably an error in the firmware, since this effect does not arise at any other resolution we tested.

Left: 1.440 x 900 pixels interpolated. Right: 1:1 display is not correct.

If a 4:3 resolution is displayed using the scaling option "Enlarged", the image is stretched in height to the size of the screen, but the width is displayed in the correct resolution. If a 16:10 resolution is displayed, this is always stretched to full screen, but not truncated, and thus provides the same result as "Full screen". The sense of this scaling option is not really understandable because of the 1:1 display.

Interpolated display of 1.280 x 1.024 pixels.

Left: 1:1 display. Right: stretched in height.

Even the smallest resolutions such as 1.024 x 768 or even 800 x 600 pixels are displayed sharply one-to-one by the Eizo monitor. Because of the small pixel distance and the resulting very small image display, this scaling will occur rather rarely in practice.

Interpolation Games

We tested how the Eizo S2242WH displays an interpolated image in gaming using a scene from "Call of Duty: World at War" in five different resolutions and compared these with each other. The result can be seen as outstanding. Hardly any difference is noticeable; even when a 4:3 resolution is stretched to full screen, there is hardly any negative effect. Only at very small resolutions of 640 x 480 or 800 x 600 pixels is the image display angular and blurred. Given the high native resolution, this effect is naturally not surprising.
