Hey Jack23Napoli,

We'd recommend reviewing this article as it provides information on using 4k displays with your Mac which could apply to your TV: Use an external display with your MacBook Pro – Apple Support (AU)

You can find information on connecting your iPad to 4k displays here: Charge and connect with the USB-C port on your iPad - Apple Support

"HDMI displays or TVs

You can connect your iPad to an HDMI display or TV with a USB-C to HDMI adapter. Adapters that support HDMI 2.0 can output video from iPad Pro and iPad Air (5th generation) at 4K resolution and 60Hz, while iPad Air (4th generation) and iPad mini (6th generation) can output video at 4K resolution and 30Hz.

The Apple USB-C Digital AV Multiport Adapter is also compatible with iPad. This adapter can output video from iPad Pro and iPad Air (5th generation) up to 4K resolution and 60Hz,* while iPad Air (4th generation) and iPad mini (6th generation) can output video up to 4K resolution and 30Hz.

Your iPad can output Dolby Digital Plus audio streams via HDMI, but not Dolby Atmos. Also note that your iPad will play HDR10 or Dolby Vision content via HDMI when HDMI 2.0 adapters that support these formats become available.

* When you use the Apple USB-C Digital AV Multiport Adapter with your iPad, its Home Screen and apps appear on HDMI displays at 1080p and 60Hz. When you begin playing video content, the resolution switches to match the content, up to 4K at 60Hz. Turn on the Match Content option on your iPad in Settings > Displays."

Thanks!
