REVIEW: Meditec SHB-22S6 TW Part 6
The brightness can be set at between 0 and 100 percent, though more than 100 steps are required, since one push of the button is not equivalent to a change of one percent. The scope of the brightness is relatively narrow; in the standard setup, the LCD’s brightness is 282 cd/m², which is equivalent to 50 %. 100 % is just a little brighter at 312 cd/m² and the lowest value is 188 cd/m² (0 percent). A lower brightness level is only possible by regulating the colour channels.
The contrast is set at 50% as standard. At this setting, one button push is equivalent to 1% on the bar. If the contrast is raised above 50%, the lightest grey tones are simply replaced with white. When the contrast is lowered, all grey levels become equally darker thanks to Frame Rate Control and the LCD only begins to replace dark grey levels with black from around 10%.
Changing the contrast on the Meditec SHB 22S6 TW brings about a corresponding change in the three colours red, green and blue.
Here, the image sharpness can be set at between 0 and 4 in digital mode. The standard value is 0.
The factory setting for the integrated speaker volume is 70 %. Even at 100 %, the speakers are very quiet – it is better to mute the speakers (0%), since otherwise they emit a peeping noise from around 50 % even when there is no sound.
OSD display time
