The result: overwhelming
POSITIVE:
- Absolutely no backlight bleeding
- No pixel -and sub-pixel defects
- By a lack of aggressive AG coating even the smallest font very sharp and clean readable. This was an important reason for me to choose a PLS display (and no e-IPS panel by LG - which are installed anywhere). Furthermore, as a result, absolutely no glitter and no 'dirty' second level.
- By a (presumed *) strongly attenuated PWM of backlight LED's no flicker in the area of the manually adjusted controller (0-100%) detectable, although the backlight is relatively slowly driven at 180 Hz (except for brightness adjustment by operating means of ambient light sensor -> See 'negative'). * For details on the PWM Please PRAD.de (S27A850 - Test from the big brother and the Forum for S24A850) read.
- Absolutely silent use
- External power supply. From my own experience I know that cheap eastern ELKO's often can lead to premature failure. Mainly affected are almost always the power supplies. If this wear so should also be true, not a problem; a new notebook power supply is then procured quickly.
NEGATIVE:
- Down-regulation of brightness. Who has a very diffuse lit office (or even like this 'Data Processor') will be surprised how bad the monitor will turn down. In daylight here a brightness of 20% is set. For me, it is bright enough. Evening 20% is definitely too bright. Even 0% is for my eyes here in the dark (it burn only 2x 11Watt ESL) too strenuous.
It may well be that in this respect'm somewhat sensitive since my predecessor (CRT) was set to be relatively dark.
Allows manual setting (0-100%) that is so for my needs nothing (except I'm doing my main ceiling light on). However, there is the possibility to activate a Eco ambient light sensor to the monitor.
This (and with different settings of the sensor) you can let the new monitor even darker adjust it, as my old monitor.
Since the brightness of the monitor that's now adjusts depending on the ambient light actually should be included under 'POSITIVE' - if he did not realize the impact instantaneously by the environment. Pulls in daylight (large skylight without curtain) a cloud over, he dims immediately comply down (ambient light, too dark). He darkens in small steps (and then lightens to the cloud in stages) disturbs a little, as there is no still image is flat. These steps control Especially falls in an already relatively darkened display on - when the display is already relatively light, the shades did not fall on (or it is no longer graded from there, but only by changes in amperage controlled illumination). Possibly is a pure matter of habit, but an inertia / Loss / integral regulator would have this on a Sensitive -and- Abflackern taught more rest.
- Here it comes with using the environmental sensor to another disorder (has already earlier pointed top). At low screen brightness at a given stage sometimes slight flicker at different frequencies can be perceived. However, we are here at a illumination brightness that you can no longer set by manual control - since we are here still below the going to adjust my regulator. So far I could this flicker relatively rare - and if, only perceive in ambient light sensor is activated. I guess you meet with the ambient light exactly to the switching threshold of the ambient light sensor where his control established. Such rules gradually tainted used in the lower brightness regions, the next level may be slightly too bright and he classifies then immediately a step back - and the game starts all over again.
Well, I've shaded with a piece of an old phone card the corresponding sensor match. So it is much slower and become even more useful. Even in my dark work environment (in the evening). If you want to run the monitor in normal ambient light in the office, you will notice of the negative characteristics of the ambient sensor hardly anything. Once a setup disable this area - and rest.
- In backlight check I noticed that during the black display (you can when you boot the Windows logo of Win 7 well recognized) is not a true black play (20% brightness / black ambient = dark room). I will in this respect even get me a calibration device - perhaps goes there still something. During normal light environment and in normal Windows everyday but that does not stand out so. Then it also looks like true black.
All summed up: I am absolutely convinced of the quality of this Monitores - although the big brother a higher LUT (but also I have with my 6-Bit LUT + HiFRC no banding), and PIP (Picture-in-Picture) support , Otherwise, this is a class monitor, I would buy immediately.
