Review on LENTION 6FT USB C to HDMI 2.0 Cable Adapter - 4K/60Hz Compatible with MacBook Pro, iPad, Chromebook & More (CB-CU707, Silver) by Ian Iknokinok

It worked! I can not believe that. I have an NVIDIA GeForce RTX 2080 on a laptop. When two Samsung TVs are connected, both running at 4096 x 2160 at 59.94 Hz, the internal display has a resolution of 3840 x 2160 at 60 Hz, all three working simultaneously. Two TVs are connected, one with an HDMI cable and the other with this product. I'm very glad it worked as advertised! (Of course I have to say that 59.95Hz looks different than a full 60Hz built-in display, but it's still a lot better than the <30Hz that many other cables can barely handle.)
