Samsung Multiport Adapter - Best Overall
Samsung's own multiport adapter is the safest pick for any Galaxy device. It carries HDMI, USB-C power input, and a USB-A port for a keyboard, which makes it a complete DeX kit in one tiny block. DeX mode launches the moment I plug it into a TV.
Check price on Amazon →I compared HDMI adapters with multiple Samsung phones and tablets to find which ones actually mirrored 4K without dropping signal.
I use my Samsung phone for presentations, casual streaming on hotel TVs, and the occasional DeX session at a friend’s house. After buying a few adapters that either didn’t fit my case or dropped to 1080p on a 4K screen, I committed to testing five of the most recommended HDMI adapters with my Galaxy S devices and Tab S tablet.
The list below covers what actually held a clean signal, what charged my phone while mirroring, and what felt sturdy enough to stay in my bag without breaking. I’ll explain where each one fits and the small gotchas I ran into.

Samsung Multiport Adapter - Best Overall
Samsung's own multiport adapter is the safest pick for any Galaxy device. It carries HDMI, USB-C power input, and a USB-A port for a keyboard, which makes it a complete DeX kit in one tiny block. DeX mode launches the moment I plug it into a TV.
Anker USB C to HDMI 4K - Best Budget
The Anker single-purpose adapter is what I keep in my backpack for when I just need to mirror. At 4K 60Hz it handles streaming and slide decks without dropouts. The braided cable is a nice touch at this price point.
UGreen USB C HDMI Hub - Best for Tablets
For my Tab S, the UGreen hub turns the tablet into a real workstation. HDMI, USB-A ports, SD card reader, and power passthrough all in one. The aluminum body stays cool under load, and I've never had a signal drop while using all ports.
Cable Matters 8K - Best Future-Proof
The Cable Matters adapter handles 8K out of newer Samsung devices and falls back gracefully to 4K when the display can't keep up. The HDMI 2.1 support also means it carries HDR signals correctly, which matters for any video work.
Belkin USB C to HDMI - Best for Travel
The Belkin is compact and built like Belkin always builds: solid and a little overpriced for what it does. But on a business trip when I cannot afford for the adapter to fail in front of a client, the reliability is worth it. Two years of use and it still works.
Common questions
Most flagship Samsung phones support DeX and HDMI alt mode, but mid-range and budget models often don't, so check your specific model before buying.
Many adapters include a USB-C power passthrough port that lets you mirror to a TV and charge the device at the same time without splitting cables.
