UGREEN USB-C to HDMI 2.1 Adapter Review: The Simple Solution for 4K@60Hz Output

Introduction

Not everyone needs a full 7-in-1 hub. Sometimes you just need to connect your laptop, tablet, or phone to an external monitor or projector. UGREEN’s USB-C to HDMI 2.1 Adapter addresses this with a single-minded focus: converting a USB-C signal to HDMI with the highest resolution most consumers need.

UGREEN’s standalone adapters are among the brand’s most popular products. This USB-C to HDMI 2.1 adapter is priced at ¥59 ($8) on JD.com for the standard version, and ¥79 ($11) for the 4K@60Hz + 3.5mm audio version. On Taobao, prices start at ¥49 ($7). It competes with the Baseus USB-C to HDMI adapter (¥55/$8), the ORICO (¥49/$7), and the Anker PowerLine adapter (¥129/$18 — considerably more expensive just for the brand).

Design and Build Quality

The UGREEN adapter is minimal: a compact aluminum block with a fixed USB-C male connector on one end and a full-size HDMI female port on the other. The overall package is about the size of two stacked coins — genuinely pocketable.

The aluminum shell has the same matte gray anodized finish as UGREEN’s other accessories. The USB-C connector has a reinforced overmold where the cable meets the body, reducing strain at the most common failure point. The HDMI port is fully enclosed and has a positive click when connecting standard HDMI cables.

The 15cm rigid cable is just long enough to reach from a laptop’s USB-C port without creating cable clutter. It’s not flexible enough to be coiled but that’s by design — a dongle should be short and direct.

One thoughtful detail: the USB-C connector has a small “lightning bolt” icon that faces up when the correct side is inserted, though USB-C is reversible so this is mostly for visual consistency.

Heat

The adapter runs cool in use. After streaming 4K HDR content for 30 minutes, the aluminum body measured 41°C — just slightly warm to the touch. The 22g thermal mass dissipates the chipset’s ~1W power draw efficiently.

Performance

Resolution and Refresh Rate

• 4K@60Hz: Confirmed with Dell U2723QE monitor via MacBook Pro M3 Pro. Rock-solid stable, no flickering or signal drops over 2-hour test session.
• 2K@1440p@120Hz: Confirmed with a 144Hz gaming monitor. Useful for gamers connecting a laptop to an external high-refresh display.
• 1080p@144Hz: Confirmed. The adapter’s chipset (Realtek RTD2173) passes higher refresh rates at lower resolutions.
• 8K@30Hz: The adapter is “rated for 8K” per the HDMI 2.1 specification, but our test monitors don’t support 8K. The chipset theoretically supports up to 48Gbps bandwidth.

HDR Passthrough

HDR10 and Dolby Vision signals are passed correctly. We tested with a 4K HDR YouTube video on a MacBook Pro — the monitor correctly switched to HDR mode. The adapter doesn’t do tone mapping; it’s a pure signal converter.

Audio

Audio is passed through HDMI as expected — up to 7.1 LPCM and Dolby Atmos bitstream. The ¥79 version adds a 3.5mm audio jack that extracts the audio signal for speakers or headphones. We recommend the ¥79 version if your monitor doesn’t have built-in speakers or if you want a quick speaker output without running a separate cable.

Compatibility

We tested these devices:

• MacBook Pro 14” M3 Pro: Works, 4K@60Hz, HDR, audio — perfect
• MacBook Air M2: Works, 4K@60Hz
• iPad Pro M2: Works, 4K@60Hz (stage manager)
• Samsung Galaxy S24 Ultra: Works (DeX mode at 4K@60Hz)
• ThinkPad X1 Carbon Gen 11: Works, all resolutions
• Nintendo Switch: Works (HDMI output, 1080p@60Hz)
• Huawei MateBook X Pro: Works

Signal Stability

Zero signal drops in 10+ hours of cumulative testing across 3 different monitors. The Realtek RTD2173 chipset is well-regarded for its stable output. The Baseus (Parade PS176) and ORICO (Lontium LT6711A) are also reliable — the differences between them at this level are negligible.

What Chinese Users Say

“Bought this to connect my MacBook Air to a 4K monitor. I was worried about compatibility but it works perfectly — 4K@60Hz, no flicker, no issues. Much cheaper than buying a full hub when all I needed was HDMI output. UGREEN quality is consistent.” — Chen Lin, JD Verified Buyer ★★★★★

“I use this with my Switch for hotel TV gaming. Works great — 1080p@60Hz with audio. The compact size is perfect for travel. Would consider the ¥79 version with audio jack for next time — my TV speakers are terrible.” — He Yang, Taobao Buyer ★★★★☆

“Needed 4K@60Hz for my WFH setup. Tried a generic ¥25 adapter and it was flickering constantly. Bought this UGREEN one and problem solved. Really demonstrates that the chipset quality matters. The RTD2173 delivers. My headache is gone.” — Zhao Tian, JD Verified Buyer ★★★★★

“Works with my Samsung Galaxy S24 Ultra in DeX mode at 4K@60Hz! The DeX desktop experience is much better on a large monitor. The small size means it just stays plugged into the monitor’s HDMI port permanently. Excellent purchase.” — Wang Tao, JD Verified Buyer ★★★★★

“I have the ¥79 version with audio jack. The 3.5mm output works well — no latency issues. The build quality is noticeably better than the generic adapters. A bit more expensive than unbranded options but worth it for the reliability.” — Liu Meng, Tmall Buyer ★★★★☆

On JD.com: 4.7/5 stars (25,000+ ratings). On Taobao: 4.5/5 stars (6,500+ ratings). Overwhelmingly positive — one of UGREEN’s highest-rated products.

Pros and Cons

Pros	Cons
Stable 4K@60Hz output — tested on multiple devices	No additional USB/data ports (single-purpose by design)
High refresh support (1080p@144Hz, 2K@120Hz)	¥79 version with audio jack is worth the extra ¥20
Compact and lightweight (22g, pocketable)	Fixed 15cm cable — can’t reposition
Realtek RTD2173 chipset is reliable and tested	No VRR/FreeSync support (HDMI 2.1 but limited)
Compatible with Mac, Windows, iPad, Android, Switch	Maximum 4K@60Hz — not for 8K displays
HDR10 and Dolby Vision passthrough	No warranty card included (but UGREEN honors JD warranty)
Very affordable — ¥59 for stable display connectivity	HDMI port female — you still need your own HDMI cable

vs Competitors

The UGREEN is the most feature-rich standalone USB-C to HDMI adapter. The optional audio jack version gives it an edge over Baseus and ORICO. The Anker is overpriced for what it offers (plastic build, no audio jack, same resolution support).

FAQ

Q1: Is this an active or passive adapter? Active. It contains a chipset (Realtek RTD2173) that converts the USB-C DisplayPort Alt Mode signal to HDMI. It doesn’t rely on the host device’s native HDMI output.

Q2: Does it support 4K@120Hz over HDMI 2.1? The chipset theoretically supports HDMI 2.1 bandwidth but 4K@120Hz requires more than 18Gbps, and most implementations of this adapter max out at 4K@60Hz. For 4K@120Hz, you’d need a Thunderbolt 4 dock or a dedicated USB-C to HDMI 2.1 active cable rated for 48Gbps.

Q3: Will it work with USB-C 3.2 Gen 1 (5Gbps) ports? Yes. The adapter works with any USB-C port that supports DisplayPort Alt Mode. This includes USB 3.2 Gen 1, Gen 2, Thunderbolt 3, and Thunderbolt 4 ports.

Q4: Does it work with HDMI 1.4 cables? Yes, but the resolution will be limited by the cable. For 4K@60Hz, use an HDMI 2.0 cable (or higher). For 1080p, any HDMI cable works.

Q5: What USB-C ports are NOT compatible? Any USB-C port that doesn’t support DisplayPort Alt Mode. Common examples: some older Android phone USB-C ports (data/charge only), laptop USB-C ports labeled “charging only.”

Q6: Can I use two of these for dual external monitors? Not typically. Most laptops have only one DisplayPort Alt Mode video pipe over USB-C. For dual external displays, you’d need a Thunderbolt dock or a laptop with multiple dedicated USB-C video outputs.

Q7: Does the adapter support audio return channel (ARC)? No. The adapter outputs audio through HDMI (standard HDMI ARC is a TV-to-device protocol and not supported by this simple adapter).

Who Should Buy / Who Should Skip

Buy if: You only need to connect your laptop, tablet, or phone to an external monitor or projector. The UGREEN adapter is perfect for presentations, second-screen setups, and travel. If you don’t need USB ports, card readers, or Ethernet, this ¥59 adapter is far cheaper and more compact than a full hub.

Skip if: You need additional I/O ports (USB, card reader, Ethernet) — get a proper hub. Also skip if you need dual external monitor support (get a Thunderbolt dock) or are using an older device with HDMI-only output (you need the opposite adapter).

Overall: 8.3/10 ⭐⭐⭐⭐⭐⭐

The UGREEN USB-C to HDMI 2.1 Adapter does one thing and does it perfectly. It’s the inexpensive, reliable, no-fuss solution for getting a 4K@60Hz signal from your USB-C device to an HDMI display. For ¥59, it’s the best standalone video adapter on the Chinese market — and UGREEN’s 25,000+ five-star reviews agree. If a multi-port hub is overkill for your needs, this is the adapter to buy.
