Strengths:
It looks nice. The fabric sheath over the rather chunky cable is eye pleasing.
Weaknesses:
Using an RTX 3080 card and an LG C1 OLED TV. Cannot set resolution/refresh higher than 4K/60. Turn on TV's "Deep Color", turn it off; pair either setting with the various bit depths offered by Nvidia control panel. Nothing works. In general NV control panel thinks the TV can do nothing more than 1280x720 under the "PC" section of resolution list, and 1920x1080 under the "Ultra HD, HD, SD" section. Cycling thru a certain sequence of resolutions will cause the control panel to offer 4K at 60 Hz, but it has to be done just right, and it never offers 120 Hz.
By contrast a 10' Club3D HDMI2.0 cable I have will let me set the system up at 4K/120 at 8 bit/channel RGB with no fuss (though after a while running a game the screen will start to flash - it's not actually a 48Gb/S cable).
Don't buy this cable, the best it can do is 4K/60 with 8 bits per channel RGB.
Additional Comments:
Cannot configure 4K/120 with RTX3080 & LG C1.
