@PerryLi I have been using Cave Painting on my monitors since January and I think that's helped my sleeping habits tremendously. Instead of 1am, I'm now turning off my screens and heading to bed around 10pm these days.

@lskang your question is about the arm GPU, not the processor itself like the rest of this thread.

What we know is that the Adreno GPU (on Snapdragon X) does not support external monitor color changes at all and so we have a workaround in the works that uses a shader instead. It's not ideal...
