I'm using this cable with an RTX 2080 Super FE USB-C connector and connecting it to a 34" 3440 x 1440 (60Hz) ultrawide monitor. It worked without any problems and the cable also supports/transmits audio. I had no issues with flickering or black screen. I didn't turn off my computer either, I just unplugged the other cables and plugged in a USB-C to HDMI cable and it worked right away. The monitor recognized the HDMI source and switched without problems. I've always liked the quality of the iVANKY cable, nice metal case for the connectors with thick braided cable. This cable seems to be very versatile since almost all devices use USB-C . I recommend iVANKY and its cables, quality material.
