Review: Works great on MacOS @120Hz - I've been trying to find an adapter that will work with my Macbook Air M2 and my Alienware monitor AW3425DW (3440x1440) at high refresh rates. The other adapters I bought only got me 60Hz. This one works perfectly @120Hz native resolution. Review: Best accessory I've purchased for Macbook Pro - 4K 120hz on M1 Pro Macbook - Purchased this so that I could use my M1(Pro) Macbook Pro with a 120hz 4K Monitor over HDMI. This isn't supported by default and when you plug in to the integrated HDMI port, you are limited to 60hz. Delighted that when I received this adapter, 120hz 4K over HDMI was supported by default - I didn't even need to update the firmware as some online forums suggested. I guess these newer built devices are shipping with the newer firmware by default. Couldn't be happier. No longer need to manually switch Displayport on my monitor! ## Features - Certified USB-C to HDMI 2.1 Adapter: Upgrade to HDMI 2.1 or future-proof your setup with the Cable Matters USB C to HDMI 2.1 Adapter; HDMI to USB C cable adapter combines the latest HDMI 2.1 standard with the versatility of USB-C; The HDMI USB C adapter (USB C adapter to HDMI) supports up to 8K 60Hz resolution on compatible displays and devices; HDMI to Type C adapter is perfect for ultra high resolution displays - Stunning 8K@60Hz / 4K@240Hz Resolution: Connect 8K or 4K 240 Hz gaming monitors and TVs to laptops, smartphones, tablets, and more with a USB HDMI adapter; USBC to HDMI adapter (USB-C to HDMI adapter) supports a maximum video resolution of 8K 60Hz with RGB 4:4:4; Enjoy high-quality video with no loss in picture quality with the Thunderbolt 3 / Thunderbolt 4 to HDMI adapter - Vivid Video Experience: The 8K HDMI to Thunderbolt adapter supports USB-C devices with DP Alt Mode support; HDMI to Thunderbolt 3 adapter is Thunderbolt 3 port / Thunderbolt 4 port compatible; USB-C adapter supports HDR for breathtaking colors; Auto Low Latency Mode (ALLM) support for lag-free gaming with the HDMI to USBC adapter; Enjoy surround sound audio for lifelike sound with the USB C HDMI adapter - Wide Compatibility: Take advantage of 8K resolution support on a newer desktop computer or laptop like Lenovo, DELL XPS with the HDMI to USB C cable 8K; The USB C HDMI cable is compatible with newer Nvidia RTX 3000 series and AMD Radeon RX6000 series graphics cards or USB4 (USB 4) and Thunderbolt 4 port on a laptop with 11th generation Intel Tiger Lake CPU and Intel Iris Xe graphics or later versions; 8K video is compatible with Intel Evo laptops using the USB Type C to HDMI adapter - Innovative and Durable Design: Premium construction of the USB Type C to HDMI adapter 8K features a premium braided cable for durability and prevents fraying; Metal connectors and aluminum enclosure of the USB-C HDMI adapter provides a premium look and feel and improves the performance of the HDMI 2.1 to USB C adapter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08MSWMXT4 | | Best Sellers Rank | 9,097 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 47 in DVI to HDMI Adapters | | Brand Name | Cable Matters | | Colour | Gray | | Compatible Devices | Desktop, Laptop, Monitor, Television | | Connector Type | USB Type C | | Country of Origin | China | | Current Rating | 3 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (957) | | Item Weight | 0.02 Kilograms | | Manufacturer | Cable Matters | | Model Number | 201388-A | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Product Finish Type | Metallic | | Specific Uses For Product | TV, PC, Monitor, Laptop | | UPC | 818707029640 | | Unit Count | 1.0 Count | | Warranty Type | Limited | ## Product Details - **Brand:** Cable Matters - **Colour:** Gray - **Compatible devices:** Desktop, Laptop, Monitor, Television - **Connector type:** USB Type C - **Specific uses for product:** TV, PC, Monitor, Laptop ## Images ![Cable Matters 48Gbps USB C to HDMI 2.1 Adapter, Supports 8K 60Hz / 4K 240Hz HDR, Thunderbolt 4 to HDMI2.1, HDMI 2.1 to USB C Adapter, Compatible with Thunderbolt 5 - Max Resolution on Mac is 4K@60Hz - Image 1](https://m.media-amazon.com/images/I/71WlITM-lhL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Is this adapter bidirectional?** A: No. It only coverts video from USB-C with DP Alt Mode or Thunderbolt 3/4/5 ports (host) to HDMI displays.

The other adapters I bought only got me 60Hz. This one works perfectly @120Hz native resolution. ### ⭐⭐⭐⭐⭐ Best accessory I've purchased for Macbook Pro - 4K 120hz on M1 Pro Macbook *by S***N on 11 April 2025* Purchased this so that I could use my M1(Pro) Macbook Pro with a 120hz 4K Monitor over HDMI. This isn't supported by default and when you plug in to the integrated HDMI port, you are limited to 60hz. Delighted that when I received this adapter, 120hz 4K over HDMI was supported by default - I didn't even need to update the firmware as some online forums suggested. I guess these newer built devices are shipping with the newer firmware by default. Couldn't be happier. No longer need to manually switch Displayport on my monitor! ### ⭐⭐⭐⭐⭐ 120Hz with M1 Pro Mac - great customer service! *by F***N on 29 January 2024* Bought this specifically to get 120Hz out of my M1 Pro Macbook Pro as I had moved to a LG C3 42 inch TV as a monitor. Asked to confirm this was the right one (it was) and they sent the instructions for how to apply and update. All done, and it worked straight away with my Sony TV (as a test). However when I got my C3, I could only get 30Hz out of it (using a known good cable that handled 120Hz directly on the PC straight off the bat and would do 60 Hz straight from the Macbook). Contacted Cable Matters and within the day I received a brand new firmware update which worked and I got 120Hz with the LG C3. They even confirmed that it would work with the latest update of Sonoma. Note: You will need a USB-C or Thunderbolt connection which supports DP Alt mode so don't get disheartened if it doesn't work after the update. A great product backed by fantastic customer service from Cable Matters (all responses were within the day). Special shout out to Grace from Cable Matters who was brilliant! ## Frequently Bought Together - Cable Matters 48Gbps USB C to HDMI 2.1 Adapter, Supports 8K 60Hz / 4K 240Hz HDR, Thunderbolt 4 to HDMI2.1, HDMI 2.1 to USB C Adapter, Compatible with Thunderbolt 5 - Max Resolution on Mac is 4K@60Hz - Cable Matters 80Gbps USB C to DisplayPort 2.1 Adapter, 16K@60hz, 8K@240hz, 4K@960Hz and HDR Support - Thunderbolt 5/4, USB4 Compatible with VR Headset, MacBook Pro, iPad Pro, XPS, Surface Pro - Cable Matters 32.4Gbps USB C to DisplayPort 1.4 Adapter, 4K@240hz, 8K@60hz, and HDR Support -Thunderbolt 4 / USB4 Compatible with Oculus Rift S, iPad Pro, iPhone 16/15 Pro, MacBook Pro, XPS, Surface --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/296169203-cable-matters-48gbps-usb-c-to-hdmi-2-1-adapter](https://www.desertcart.pe/products/296169203-cable-matters-48gbps-usb-c-to-hdmi-2-1-adapter) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-15*
