Default LCD Contrast Test

This is the app I used to test: https://play.google.com/store/apps/d...eencolor&hl=en

Contrast - Black: Squares 6 and above are clearly distinguishable, 4 and 5 are just about visible
Contrast - White: All squares are distinguishable
Color Scale - Brightness: All squares are distinguishable
Color Scale - Saturation: Highest 4 squares are equally saturated on all but orange, light blue and grey


This is with an AUO panel and default white balance - I'm hoping someone with a JDI panel (or indeed another AUO) can weigh in with their observations.

I have the JDI (Novatek) and confirm the same crushed black levels with Color Test and Display Tester - except that only 7 and above are distinguishable. White contrast and brightness are the same as yours, but color saturation tests vary between the two apps .... personally I trust Display Tester better, which shows blues only are moderately over-saturated.

The crushed blacks are definitely noticeable in dark scenes with or without X-Reality. The panel is quite warm compared to others, and the White Balance settings are somewhat useless since they involve an overlay filter, it seems, and so just darken the screen.

Yeah not too happy with the white balance setting compared to voodoo/cm colour settings on my old galaxy s, but gets the job done for the most part. Call me crazy but I like it even warmer than default

And hopefully there will be some software improvements to the display in Kitkat

Assuming you don't like the idea of dismantling your phone to check the back side of the panel you might want to follow my instructions in this post.

Z1c black w9 telenor-hungary auo-panel (no "blue" problem)

To dark, the dark areas (too high contrast/gamma), dislike me...
But, good deep-black.

Automatic background light regulation not a good idea (automatic brightness: OFF, x-reality: OFF ).



- sorry my bad english -
