The CalDigit USB-C to HDMI 2.1 adapter solves this problem by providing an easy and affordable way of connecting your computer to a wide variety of monitors up to 8K in resolution. This adapter is a convenient solution for those looking to add a video output to a Thunderbolt 3, Thunderbolt 4, USB 3, or USB4 Type C equipped computer. It features high grade components and extensive emissions shielding in order to deliver you the best and consistent video quality.

Review: I have a pile of DP to HDMI adapters I've tried. This CalDigit one is the ONLY one I've found to work reliably and I have four of them plugged in, currently. Even the CableMatters adapter doesn't work as well as this one. If you are still having issues with this adapter, it is probably your cable. Before you blame the adapter, combine it with a RUIPRO Fiber Optic HDMI cable. Yes, even down to 6ft or even 3ft in length.
Review: This adaptor is not able to display 4k at higher refresh rates than 60hz when using HDR on a MacBook Air M3.
