Every Sony Bravia 3 shares one port layout, whatever size you bought: four HDMI 2.0b inputs at 18 Gbps, two USB-A, optical out, Ethernet and the composite/component hybrid jack. That means 4K@60Hz is the ceiling — no 4K@120Hz, no VRR — so a High Speed HDMI cable is enough and an Ultra High Speed one buys you nothing. HDMI 3 is the eARC port for a soundbar. Pick your size below; the cables are the same either way.

Notes & Compatibility
All four HDMI ports are HDMI 2.0b (18 Gbps, 4K@60Hz max) on every size. HDMI 3 carries eARC. The 60 Hz panel means no 4K@120Hz and no VRR — an Ultra High Speed HDMI cable will not unlock anything here. ALLM is confirmed on all four HDMI ports across the range: Sony’s specification sheets for the 43-inch (K-43S30) and the 55-inch (K-55S30) both list Auto Low Latency Mode as “Yes (for HDMI 1/2/3/4)”. eARC and ALLM are the only HDMI 2.1 features this line carries; Sony lists VRR as unsupported.
