Satechi’s new USB-C cable and adapter convert USB-C video to the latest HDMI 2.1 format with 8K resolution support. In addition, the company has launched a USB-C Ethernet adapter that permits devices like the iPhone 15, iPad, Mac and more to connect to fast 2.5 Gigabit Ethernet.
As Apple’s consumer computers no longer offer an Ethernet port, the 2.5 Gigabit Ethernet adapter is essential to take advantage of high-speed local networking.
USB-C cable and adapter with HDMI 2.1 8K support
Your Mac doesn’t support external 8K displays unless it’s an M2 Pro or M2 Max model. To connect an M3-based iMac, MacBook Air Pro or MacBook Pro to an 8K display, you’re going to need an adapter. Thankfully, Satechi’s new USB-C to HDMI 2.1 8K cable and adapter have come to the rescue.

The cable connects to your Mac’s USB-C port, giving it HDMI 8K video output at 60Hz. The adapter outputs a Mac’s display to an HDMI-enabled monitor.
“For those prioritizing smoother motion and reduced motion blur in their visual content, the devices also offer a 4K/120Hz output option,” Satechi said.
2.5 Gigabit Ethernet doubles the performance
The only Apple computers to incorporate Ethernet are the Mac mini (1Gb Ethernet, configurable to 10Gb Ethernet), Mac Studio (10Gb Ethernet) and Mac Pro (10Gb Ethernet). To connect a Mac laptop to Ethernet, you definitely need an adapter like Satechi’s new USB-C 2.5 Gigabit Ethernet Adapter.

It doubles the performance of traditional Gigabit Ethernet, giving you faster network speeds and file transfers while being downward compatible with 1-gigabit devices. So, why would anyone need 2.5 Gigabit Ethernet in the first place?
Anyone into video editing, gaming or streaming knows that faster Ethernet accelerates retrieving media assets and backups on their NAS storage.
Gigabit Ethernet maxes out at 125 megabytes per second, meaning it takes at least eight seconds to transfer a one-gigabyte file. With 2.5 Gigabit Ethernet, the same file transfers in a little over three seconds, or at 312.5 megabytes per second.

So whether gaming, streaming or video editing, you’ll benefit from faster home networking (you’ll also need a router that supports faster Ethernet standards). On Windows PCs, this accessory also supports Ethernet pass-through mode.
