I bought this product specifically to stream 4K at 60 fps from my gaming PC to my TV. My TV is a 55" 4K HDR Toshiba Fire TV. My graphics card has an HDMI 2.0 output and I know my TV can stream 4K video at 60Hz (as shown in the manual and I verified it with a YouTube video (tested from the app on the Fire TV). If I set my computer to 60 hertz in 4K, the signal drops. It's stable at 30 hertz, but that's almost impossible for most of my games, and it makes it very difficult to stream anything from my computer. I am very disappointed in this product and would advise anyone looking to buy it to look elsewhere (and make sure the product you choose clearly states that it can support 4K at 60Hz , if you wish).
