MacBook Pro 14” 2021 PWM screen flickering?

[RiverOak]

Has anybody used the Iris-tech app? Apparently it gets rid of dithering by forcing an 8bit colour profile and uses whitepoint to lower brightness so the pwm stays at the 14.8 max and not lower.

I tried it, but it was not able to change the bit depth of the native panel. Has this been changed recently?

I don’t know. But when chatting to the developer, he was quite confident it would do it. By then again he wasn’t aware of the constant 14.8 pwm frequency for instance on the 14” so not sure how much real works testing he’s had on the 14”.

Anyone tried the M2 machines? Do they also have the same problem?

I came across this command from the ledstrain.org forum which is supposed to disable temporal dithering:

sudo nvram boot-args="enableDither=0 PE_i_can_has_debugger=1 iomfb_RuntimeProperty_enableDither=0"
