REVIEW: Meditec SHB-22S6 TW Part 9

But let us focus on the subjective impression of the picture: As can be expected of a monitor with a TN panel, the Meditec’s viewing angles are poor vertically and just about good horizontally. Viewing angle stability on the Meditec SHB 22S6 TW is comparable with that of the FSC H22-1W, whereas the Samsung 226BW performs a little better.

Generally, more sensitive users would be better advised to purchase a monitor with a VA (MVA/PVA) or IPS panel, since slight colour and contrast changes can be perceived even when you move your head when sitting in front of the screen. In addition, because of the poor vertical viewing angle, a monocoloured wallpaper never has exactly the same tone at the top and bottom of the screen. However, this is true for all monitors that feature a TN panel.

Apart from small brighter patches of 0,3 – 0,5 cm, the illumination is very even.

When viewed with the naked eye, the illumination of our test monitor is very even. Narrow stripes of light are only visible at the edges, especially at the top and bottom; these are probably caused by the panel’s being too taut. However, there are no clouds or star-shaped bright patches.

When the brightness distribution is measured, the Meditec SHB 22S6 TW also provides a good result. Apart from those on the very edge of the screen on the left, the deviations from the guide value are all within a very good range. The largest deviation is in the top left hand corner, but this is smaller than the largest deviation on the FSC H22-1W.

Measurements and calibration

Normally, we use the so-called native settings of a monitor to gain the largest possible colour space. Since the Meditec SHB 22S6 TW’s colour space is larger after calibration and since banding is visible before calibration, we assume that the calibrated settings are closer to the monitor’s native settings than the standard values of 50.

The sRGB colour space, which is important for most users, being used in Internet sites and digital cameras, is covered well overall by the Meditec SHB 22S6 TW– as is the ISO coated printing colour space. The LCD can cover a large spectrum of yellow and red tones, but does not cover all green and blue tones of the sRGB colour space completely.

The coloured box represents the monitor’s colour space; the grid shows the sRGB colour space. Colours outside of the coloured box cannot be displayed by the monitor. The illustration is three dimensional, with the light colours and white to the front in the left hand picture. The right hand picture shows the view from the back, with the dark colours and black to the front of the image. In those places where the coloured box goes past the grid, the monitor’s colour space exceeds the sRGB colour space; in those places where the grid protrudes past the coloured box, the monitor’s colour space is smaller than sRGB.
