    Hi! I just wrote a tool in order to fix the bad white point on my 16.2" 2021 MacBook Pro. After checking in a shop I saw that there was noticeable inconsistency in factory calibration between units, leading to some displays being more red, more blue, or worse like mine with a depressing...

    iPhone 13 Iphone 13 Abysmal Video Quality?

    Hello, everyone I'm a very loyal Apple user, therefore there's no phone for me other than the iPhone, and I recently upgraded from an Iphone XR to a 13 and I love it. Everything about the phone is amazing, especially the screen (once again, coming from the very cheaply made XR). There's one...

    iPad Pro M1 12.9” - do you max out the brightness when watching DV/HDR10 movies?

    On my OLED TV, the OLED Light (equivalent to iPad’s brightness, despite its name) is set to maximum, because that is what is recommended. HDR10 and Dolby Vision content is tone mapped from darkest to brightest areas and the maximum brightness ensures highlights get bright while darks stay dark...

    Why is getting 4K YCbCr444 @ even 60Hz so difficult?

    A lot of discussion exists on getting 4K @ 60 or 120Hz with 10-bit HDR and 4:4:4 chroma subsampling (YCbCr444) with an external monitor, but seemingly mostly on the M1 forums. And even then there's little discussion about how to actually get it to work beyond the discussion of the theoretical...
