Two points to remember:
1- The display offered by this screen is remarkable not fault on this point.
2- The screen produces a continuous high-pitched whistling sound and very unpleasant when the brightness is reduced (mandatory reduction because the default brightness setting is too powerful for prolonged use). The whistling reminds one we hear sometimes with old CRT televisions. It becomes clearly audible, approaching about 90% of the default brightness and increases below this setting. It is inaudible to 100%. That night whistling sharply in ease of use of the screen.
Knowing this flaw, I do not rachèterais this screen if it again.
Regarding the note I attribute two out of five stars because failure whistle and the display quality seem totally contradictory. I never imagined that such a defect could be a product of this level.
A clarification: I use the screen only for the photo (amateur use of a raw file processing software + visualization of course photos).
