Just wanted you to know my very specific test situation as I had to work with it. So if I can use a different entry and exit I will update my review. But for this test I have an HP Specter x360 13 inch with a 4k OLED touchscreen and I used this dongle along with two 8k/60-4k/120 HDMI 2.1 cables to connect to my VIZIO OLED which It may be the Specter laptop's fault - it may only be able to output 4k/30 (the screen spec says it outputs 4k/60 ), so I'll rate it three stars for now until I find other options to test.
