Dissapointing given the price
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.

Incapable adapter
I was forced to buy a few different brands one after another, because they all seem to make claims that are not entirely true. In this adapter's case, it cannot achieve HDMI 2.1 spec to the word. When attempting 4K 120Hz HDR with LPCM audio, the adapter can only go up to 4:2:0 compressed format, which means 'fuzzy' colours as it is an old way of transmitting compressed lossy video image data to a screen, pure uncompressed RGB requires higher bandwidth, which is what the HDMI 2.1 spec allows for! This adapter is incapable of RGB 10bit @ 120hz in 4K, as such it should not be labeled 'HDMI 2.1' adapter. Those who are after a Thunderbolt 3/USB4 compatible 8K adapter, to help you avoid having to make returns (I'm doing you a favour here by saving you on headaches), in the end the one that worked without issue was https://www.amazon.co.uk/dp/B0B57T77H3

Limited to 4k 60hz with macbook air m3
This adaptor is not able to display 4k at higher refresh rates than 60hz when using HDR on a MacBook Air M3.

MacBook Pro M4 Maxの性能をフルに引き出す、現時点で唯一無二の選択肢
【 注文のきっかけ 】 新型のMacBook Pro M4 Maxを導入し、デスク環境を8Kモニターで構築しようと考えたのがきっかけです。本体のHDMIポートを使わずに、Thunderboltポートから高リフレッシュレートかつ高解像度で出力できる信頼性の高いアダプタを探しており、信頼のCalDigit製を注文しました。 【 良かった点 】 ■ 圧倒的な描画スペック HDMI 2.1規格にしっかり対応しており、8K出力はもちろん、高リフレッシュレートでのヌルヌルとした動きを体感できます。HDRや10ビットカラーの階調も非常に美しく、クリエイティブワークにおいて妥協のない映像環境が手に入りました。 ■ 安定の接続維持 安価な変換アダプタにありがちな、スリープ復帰時の暗転やチラつきが一切ありません。M4 Maxのパワーをロスなくモニターに伝えている実感が持てます。 ■ 洗練されたビルドクオリティ CalDigitらしい堅牢な作りで、放熱性も考慮されている印象です。長時間高負荷な映像出力を行っても、動作が不安定になることはありませんでした。 【 気になった点 】 ■ ケーブル自体の硬さ 断線防止のためか、ケーブル部分がやや太く硬めです。取り回しに少し慣れが必要ですが、その分耐久性は高そうなので、据え置きでの使用であれば問題ありません。 【 総評 】 ハイエンドなMacBook Proユーザーや、最新のゲーミングモニター・8Kテレビを活用したいプロフェッショナルな方に最適です。 安物を買って相性問題に悩むくらいなら、最初からこれを注文しておくのが正解だと断言できます。最高のスペックをフル活用したいなら、必携のアイテムです。

Caldigit delivers, but for a price, as usual. Perfect for Mac M series.
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).

信頼のCaldigit製品
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。
