I recently had the opportunity to test the Rock Cables USB-C to HDMI adapter (Model Number: Rock Cables), a cable promising 4K@60Hz performance. This review details my experience using this adapter with various devices, from my MacBook Pro to my Samsung Galaxy S22, highlighting its strengths and weaknesses.

The Rock Cables adapter boasts a sleek silver design with a durable braided nylon cable. The 6.6-foot length provides ample reach, and the aluminum HDMI connector seems robust. The key selling point is the advertised support for 4K@60Hz resolution, which is crucial for high-quality video output. The claim of backward compatibility with lower resolutions is also a valuable feature.

I tested the adapter with several devices and resolutions. On my MacBook Pro, achieving 4K@60Hz was seamless. The picture quality was excellent, with vibrant colours and crisp detail. I also connected my Samsung Galaxy S22, successfully mirroring my phone’s display onto a 4K monitor. The performance remained consistent throughout my testing period, with no noticeable lag or signal dropouts. I also tested lower resolutions (1080p and 720p) with various devices and experienced flawless performance, confirming the claimed backward compatibility.

However, it’s important to note that, as the product description mentions, the USB-C port on your source device needs to be a full-pin type-C port and the receiving device must support 4K@60Hz to obtain optimal results. I did encounter slight compatibility issues when attempting to use this with an older monitor that did not fully support HDMI 2.0. This was expected, given the limitations of the older hardware.

Pros:

• Excellent 4K@60Hz performance with compatible devices.
• Durable braided nylon cable and robust connectors.
• Good length (6.6 feet).
• Backward compatibility with lower resolutions.
• Sleek design.

Cons:

• Compatibility issues with older, non-HDMI 2.0 monitors (as expected).
• Requires a full-pin USB-C port on the source device.

Overall, the Rock Cables USB-C to HDMI adapter provides excellent value. The 4K@60Hz performance is impressive, and the build quality feels premium. While compatibility issues are possible with older devices (as clearly stated in the product description), the adapter delivers on its promise for most modern devices. I would recommend this adapter to anyone needing a reliable and high-performance way to connect their USB-C devices to a 4K monitor or TV. Just ensure your hardware meets the requirements stated.
