I bought this cable to enable 4K 120Hz on my RTX 3080 PC and LG C9 OLED TV. The image dropped for half a second about every 30 seconds. This cable may not be able to handle 48Gbps or similar. Edit: - I tried another brand of cable and it's the same, the problem turned out to be the TV itself, LG just released v5.00.30 and the problem was fixed.
