There is no single HDMI port map for every Sony Bravia TV. The port that supports 4K at 120Hz, eARC, or a gaming feature depends on the exact model and year. Check the labels beside your TV’s HDMI sockets, then confirm the port and signal requirements in Sony’s HDMI terminal table for your model.
Which HDMI port on my Sony Bravia supports 4K 120Hz?
On applicable Bravia models, Sony’s 2025, 2024, and 2023 terminal tables identify HDMI 3 and HDMI 4 for 4K 100p/120p signals. That does not mean every model in those years supports the signal: check the entry for your exact model and confirm the port labels on the TV. Sony updates its HDMI 2.1 feature chart separately by series and year, so a series-level feature listing is not a substitute for a model-specific port check.

For supported 4K 100p/120p sources, Sony specifies an Ultra High Speed HDMI cable and may require changing the port’s HDMI signal format to an enhanced option. The exact setting name and available formats vary by model; use the matching support page or manual rather than assuming a setting applies universally.
Which HDMI port should I use for a soundbar?
Connect the TV’s HDMI IN socket marked eARC/ARC to the soundbar’s TV OUT socket marked eARC/ARC. Sony’s soundbar connection instructions say to check for that label: without it, the TV port does not provide eARC/ARC. Both the TV and soundbar must support the relevant audio-return feature.

Sony describes eARC as an improved version of ARC that carries audio through HDMI from the TV to decoding equipment such as a receiver or soundbar. It can pass high-quality sound, but the capabilities available depend on compatible equipment at both ends. See Sony’s explanation of eARC.
Does every HDMI port support eARC?
No. Use the port specifically marked eARC/ARC for audio return; the other HDMI inputs may serve different purposes and need not have the same capabilities. Sony’s model-year feature chart tracks eARC, 4K120, 8K60, VRR, and ALLM by series. For example, its 2025 chart lists BRAVIA 5 and BRAVIA 8 II with 4K120, eARC, VRR, and ALLM, while BRAVIA 3 and BRAVIA 2 II are listed with eARC and ALLM but not 4K120 or VRR. In the 2024 entries, BRAVIA 9, 8, and 7 are listed with 4K120, eARC, VRR, and ALLM; BRAVIA 3 is listed with eARC and ALLM. These are Sony USA series-level entries, not guarantees for every regional variant or individual model. Some earlier feature support may also depend on a software update.

What HDMI cable do I need for my Bravia TV?
Choose a cable for the signal you want to carry—not simply because the television is a Bravia. Sony’s connection guidance discusses Premium High Speed HDMI cables rated for 18 Gbps and Ultra High Speed HDMI cables rated for 48 Gbps. Some high-bandwidth 4K 100p/120p connections require the Ultra High Speed category; ordinary connections do not automatically require it. Confirm the TV, source device, and signal-format requirements before choosing a cable. Sony’s HDMI cable guidance explains the categories and connection considerations.

Why is there no sound through HDMI ARC?
A plugged-in HDMI cable alone does not establish an audio-return connection. Sony’s troubleshooting guidance recommends checking compatibility, the labeled terminals, device-control settings, audio output settings, and the cable itself. Menu names differ across Bravia models, so consult the manual for your TV and soundbar when a setting is not where expected.
- Confirm the connection. Make sure the TV’s HDMI IN eARC/ARC port is connected to the soundbar or receiver’s TV OUT eARC/ARC port.
- Check compatibility and control settings. Both devices need ARC/eARC support. Check HDMI control on both devices and enable BRAVIA Sync on applicable TVs.
- Check audio output. Set the TV to send sound to the connected audio system and verify the audio-return settings for your model.
- Reseat or replace the cable. Try a known-good compatible cable. While troubleshooting, avoid long cables, adapters, and extenders.
- Power-reset and isolate. Restart the devices. If the problem continues, Sony advises testing with the audio system as the only HDMI device connected to the TV.
If one device lacks ARC/eARC, the feature cannot work between them; optical audio or another connection may be an option depending on the equipment. For model-specific steps, see Sony’s HDMI ARC/eARC troubleshooting guide.
