Wondering about PWM Flickering presence on 4K version? Could someone confirm that 4K LCD screen not used PWM method for controlling brightness. Very important for human eyes
While I don't think my 4k model had PWM, i was only able to confirm upto 1000Hz. (i used my camera to compare it to an XPS 15 9570 which has 1000Hz PWM, both at min brightness) i did not see any waves of brightness on the screen as i cycled through the shutter speed.

Guys, 2 months ago you said that you will test the 4k model.
Well, is there any news about this specific 4k model? I would really love to read a review about it.
While i might not be able to provide you with the exact same results as notebookcheck's testing methods, i was able to test my 4k aero 15x with DisplayCAL and an Xrite i1 Display pro. Brightness distribution was good, (once i go home i will upload the pic) it scored 99.3% AdobeRGB and nearly 1600:1 contrast. for PWM see what i wrote above. Now, a good surprise, the screen was bright at 400 nits! It was subjectively as bright as my Dell XPS 15 9570's 4k panel. I forgot to jot down the display's model, but it was an AU panel. I do apologize for lack of evidence (except for brightness and distribution) I wasn't expecting on returning the unit.
