    stuttering image with apple tv on external monitor via hdmi

    So yesterday I connected my 4K TV to my MBP via the HDMI Port to watch apple TV.

Image quality was flawless otherwise. This was...

    I bought a USB 3.0 (USB-A) to HDMI adapter but was too late to notice it wouldn't work with Mac - Windows only; as such my Mac simply won't recognize my Sony TV. Unfortunately a return is not possible due to the damaged package, so I thought since there's the Device Firmware Update mode which is...

    Hi :) I'm wondering if anyone is using an M1 Mac and Kodi for HTPC purposes? Or might test it for me ;) I know that Big Sur supports HDR output, but this might not translate to video content being put out via HDMI with the proper HDR metadata and so on. I also see that the first release of Big...

    I’m currently using an HDMI 2.0 cable. Would I benefit by upgrading to an HDMI 2.1 cable? As far as future proofing goes, I wonder if the next Apple TV hardware will take advantage of the HDMI 2.1 technology.
