The device had the same times on some (sub) pixel errors, which the good impression but clouded. On the other hand, they are from a normal viewing distance not annoying, but must be actively sought. Therefore, the unit remained. Combined with the 5-year warranty, it would have to be repaired due to deterioration. The image quality is excellent, the custom calibration helpful, but the image changes only marginally. ie, the default setting is ever quite useful. Glow or so I do not see or I do not want to see ;-) The auto shut-off is pleasant, the automatic brightness control unusable in terms of both calibration and the control characteristic, but can be switched off. The toolbar is not illuminated and therefore in a dark room practically only by trial and error to use. But okay, in practice should not be changed anyway a calibrated monitor. Speakers enough but is not a pleasure. In sum, I can recommend the device for the intended purposes well. Clear is still room for improvement, but price relative the device is good.
