[Designed for Microsoft Surface] Cable Matters 48Gbps USB-C to HDMI Cable 6 Feet / 1.8 Meters Supports 4K 120Hz and 8K 60Hz HDR – USB4, Thunderbolt 3 and Thunderbolt 4 Port Compatible

TL;DR version:This uses the Synaptics VMM7100 (Spyder) chip. It will convert USB-C to HDMI 2.1. It supports 4K@120Hz and VRR.I have a laptop that has three USB-C/Thunderbolt ports, but no HDMI port. This cable allows me to connect to an HDMI display or TV. Keep in mind that Thunderbolt supports DisplayPort, which is not compatible with HDMI/DVI. This cable contains the necessary Synaptics VMM7100 to convert the signal to HDMI 2.1.I tested it on an LG B3 OLED at 4K/120Hz, and it worked. VRR technically worked, but was a little glitchy. I also tested it on a Vizio 4K television (no VRR) and it worked at 2160p/60Hz (4K). I wasn’t able to test 8K as I don’t have an 8K display (who does?). I also tested this cable with my Steam Deck. It worked fine with both picture and sound at 1920×1080.The cable seems well built and isn’t too thick. It also has a small hook and loop (Velcro) cable tie attached to it, which is convenient.Two minor issues come to mind with a product like this. One, the signal conversion may introduce too much lag as the chip in the cable needs to convert the DisplayPort signal to HDMI. So, if you’re a hardcore gamer you’ll want to pass on this and use a monitor with an actual DisplayPort connection (you’ll want to use a variable refresh display as well). Two, since there’s an actual chip inside the cable, the ends get warm. Not that big of a deal I know, but worth mentioning.I have various other display cables from Cable Matters that have been in service for years, and I’ve had no problems with them. [...]
