CalDigit USB-C to HDMI 2.0b Video Adapter - 4K Display Support, HDR, Compatible with Thunderbolt 3/4 / USB 3.1 / USB4 for Apple MacBook Air, 2016+ MacBook Pro (USB-C to HDMI 2.0b)

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.

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

Really good quality cable. Well made and works well.

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。

Using it with wqxhd monitor, thing is cool as can be. Coming from an hdmi adapter that started showing glitches an becoming incredibly hot this is such a better performance. Caldigit always trusted also, just buy it if you need this conversion.
