It depends on the source device. HDMI 2.1 devices generally require the 48GBPS cable for full feature support, like 4k/120 with HDR video and varible refresh rate. 18GBPS cables can support 4k/120 without HDR and 4k/60 with HDR. Series X, PS5, computer with a recent AMD, Intel, or NVidia GPU, home theater receiver with HDMI 2.1 4k/120 or 8k/60 support, or Apple TV 4k generation 3? Get the 48GBPS cable and use HDMI 3 or 4.

For HDMI 2.0 (ports 1 and 2 on the TV), an 18 Gbps cable will work perfectly, since this cable will handle the maximum video resolution and audio supported by HDMI 2.0. For HDMI 2.1 (ports 3 and 4 on the TV), you can use either an 18 Gbps cable or a 48 Gbps cable. Choosing which one depends on several factors... - Use an 18 Gbps cable for 4K HDR video content at 60 frames per second (4K@60Hz) and HD audio, which covers most movies and music. - Use a 48 Gbps cable for 8K HDR video content, 4K content at 120 frames per second, and certain gaming applications.
