In this video I'm showing you two different video cables so you can connect your MacBook Pro to an external 4K monitor at 4K 240Hz. One cabe is a HDMI to HDMI 2.1 cable and the other cable is a USB-C to DisplayPort 2.1 video cable, sometimes called a Thunderbolt to DisplayPort cable or Type C to DisplayPort video cable.

Did you know that the base M4 MacBook Air can also output a 4K 240Hz video signal? Check out this video youtu.be/kzv65EmX6F4

Links to stuff used in the video and my usual stuff:

For the ACASIS website use the promo code TB20 for 20% off the TB501 and TB501 Pro. For everything else use the promo code David15 for 15% off. I don't know how long the TB20 promo code will last, if it is not working then use David15 for 15% off the TB501 and TB501 Pro.
