### ⭐ Limited to 4k 60hz with macbook air m3
*by S***N on 2 January 2025*

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

### ⭐⭐⭐⭐⭐ Great adapter - highly recommend!
*by M***M on 13 July 2026*

Great adapter - highly recommend!

### ⭐⭐⭐⭐⭐ 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
*by し***ん on 28 February 2026*

【 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。
