CalDigit USB-C to HDMI 2.1 8K Adapter Dongle - High Refresh Display, HDR, 10 bit, Compatible with Thunderbolt 3/4 / USB 3.1 / USB4 for Apple MacBook Air, 2016+ MacBook Pro (USB-C to HDMI 2.1 (8K))

This adaptor is not able to display 4k at higher refresh rates than 60hz when using HDR on a MacBook Air M3.

TS4に使用しています。映像関係のケーブル類は安物を使うと予期せぬトラブルが起きることがあるので、お値段高めですが信頼できるこちらの商品を選びました。今のところ問題なく安定して使えています。個人的に価格は気になりませんが、HDMI端子が大きいところが少し気になります。写真左側が同社のHDMI2.0までのアダプター、写真右側が本製品です。全長はどちらも同じ、HDMI端子部は本製品の方が長いですが、幅と高さは若干ですが本製品の方が短い・低いです。

This converter is more expensive than others, but entirely worth it if used on a daily basis, like most CalDigit products (I also own a TS3). I use it on a Mac M1 and it reaches 85 Hz on an AW3821 WQHD+ (3840 x 1600).

CalDigit TS4で他のメーカーのアダプターを使用した際に認識しなかったので、純正品と考え購入しました。 少し大きいですが問題なく使用できています。

The CalDigit USB-C to HDMI 2.1 8K Video Adapter let me down. Even though it has great reviews I have found it to be of inferior performance compared to offerings from other manufacturers, making it hard to justify the price premium paid for this product. On top of this, it's worth noting that the adapter lacks DolbyVision support. If you're planning to connect it to an iPad or device capable of outputting DolbyVision I would avoid this adapter (see pic attached). For SDR / HDR10 output it will work fine but it's overall performance is still worse compared to other adapters. The adapter I went for in the end is (https://amzn.eu/d/jm5iyYy), I hope this saves you the hassle of trying different products and dealing with returns. The build quality of the adapter is great and in line with other CalDigit products, ease of use also receives a 5-star but they won't make up for the other drawbacks.
