LG 27UD69 is working fine (CR+BR) #88

Open marckrenn opened 6 years ago

marckrenn commented 6 years ago

In combination with a MBP 2017.

As the LG craps out over a contrast of 72 anyway, I've naïvly offseted its contrast by changing the following LOC:

https://github.com/marckrenn/BrightnessMenulet/blob/27UD69W/BrightnessMenulet/LMUController.m#L80

Now, when

the brightness of the LG now matches the one of the MBP. Hooray!

Same should also apply to other LGs with the same panel as well:

I have LG 24UD58 and your build does not works. As I see it can't get the current value of BR and CR.
I have the same issue https://github.com/kfix/ddcctl but I can set the absolute value with ddcctl.
For example ddcctl -d 1 -b 50 -c 50 successfully set brightness and contrast to 50. The issue is that I can't get current values.

Here is the log of running your build in cli:

Hey @zhovner,

try this fork here, Florian added a proper calibration GUI.

I'm currently not at home, so I can't tell the exact values I'm using, but I think I'm using MIN: -10 and MAX: 80 to match my MBP 2017.

Hope that helped 😃

Have a great weekend,

Marc
