HDMI Ports Explained: PS5, Xbox, Soundbars & TV Setup Guide
- Most newer TVs boast three or four HDMI ports and at first glance, they appear identical.

- All HDMI ports transmit both video and audio, but they differ in bandwidth capacity, which dictates the types of devices they can optimally support.
Most newer TVs boast three or four HDMI ports and at first glance, they appear identical. They share the same physical shape and work with the same HDMI cable, but not all ports support the same features. Choosing the wrong one can limit performance, whether you’re gaming on a PlayStation 5, enjoying immersive audio from a soundbar, or simply trying to get the most out of your streaming devices.
The good news is understanding which HDMI port to use is straightforward. It’s a matter of knowing what each port offers and matching your devices accordingly.
HDMI Port Types Explained
All HDMI ports transmit both video and audio, but they differ in bandwidth capacity, which dictates the types of devices they can optimally support. Plugging a device into the wrong port won’t cause damage, but it may prevent you from accessing the full range of features, and performance.
An HDMI 2.0 port, for example, can handle 4K resolution at 60Hz, High Dynamic Range (HDR), and Audio Return Channel (ARC) audio – suitable for streaming media players and cable boxes. In contrast, an HDMI 2.1 port supports 4K at 120Hz (or even 8K at 60Hz), Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Enhanced Audio Return Channel (eARC), making it ideal for next-generation gaming consoles like the PlayStation 5 and Xbox Series X. HDMI 2.1 can sometimes achieve 4K at 240Hz using Display Stream Compression (DSC).
Then there’s ARC/eARC, or the Audio Return Channel. This port, which looks like a standard HDMI port, sends audio back from your TV to a soundbar or AV receiver. ARC supports standard Dolby Digital 5.1, while eARC supports uncompressed Dolby Atmos and DTS:X for a more immersive audio experience.
How to Tell Apart Your HDMI Ports
Many TVs label their HDMI ports directly on the back of the unit. Look for markings indicating HDMI 1, HDMI 2, HDMI 3, and so on. You’ll also often find ARC or eARC labeled. Some manufacturers print descriptions beneath the labels, specifying features like “4K120,” “VRR,” “Game,” or “Enhanced.” If a port lacks a specific description, it’s generally safe to assume it’s a standard HDMI 2.0 port – except for the one designated as ARC.
Consulting your TV’s user manual is always a good idea for detailed information about each port’s capabilities.
Which HDMI Port Should I Use?
Once you’ve identified your TV’s HDMI ports, it’s time to connect your devices. Here’s a guide:
| Device | Recommendation | Why |
|---|---|---|
| Soundbar / subwoofer / home theater receiver | ARC or eARC port | Sends audio from TV back to sound system. Required for Dolby Atmos. |
| Apple TV 4K (if using with HomePod) | eARC port | Apple TV 4K needs eARC to route TV audio back to HomePods. |
| Gaming consoles (PS5, Xbox Series X) / gaming PC | HDMI 2.1 | High-bandwidth port needed for 4K120, VRR, ALLM, low-latency gameplay. |
| PC | Any HDMI port | But HDMI 2.1 is recommended for high-refresh-rate output and VRR support. |
| Streaming devices (Roku, Fire TV, Chromecast, Apple TV if not using HomePod audio) | Any HDMI port | 4K streamers only need standard bandwidth. No HDMI 2.1 requirement. |
| Blu-ray / UHD disc player | Any HDMI port | Handles normal 4K60 HDR bandwidth. No need for HDMI 2.1. |
Is There a Typical Port Layout I Can Follow?
While layouts can vary, a common arrangement exists. Many TVs have three or four HDMI ports, with a typical configuration. However, it’s always best to verify the specifications of your specific TV model.
For example, older Samsung models often feature only one HDMI 2.1 port (typically labeled HDMI 3 or 4), while newer models include more. LG TVs, particularly OLED models, usually offer multiple HDMI 2.1 ports. Sony generally reserves HDMI 3 and 4 for HDMI 2.1 connectivity. TCL limits HDMI 2.1 to its mid- to high-tier models, as do Panasonic and Hisense (the U7 and U8 have two HDMI 2.1 ports). Vizio also restricts HDMI 2.1 ports to its high-end models, such as the P-Series and OLED sets.
Philips equips its newer OLEDs with two to four HDMI 2.1 ports. Sharp, typically features standard HDMI ports across most of its models.
A general guideline to follow:
- HDMI 1: Streaming stick or Blu-ray player
- HDMI 2 (usually HDMI 2.1): Gaming console
- HDMI 3 (usually HDMI 2.1 or ARC/eARC): Soundbar
- HDMI 4 (usually HDMI 2.1): Secondary device or PC
If your TV has only one HDMI 2.1 port, prioritize connecting your primary gaming device to it.
As the HDMI standard continues to evolve with the introduction of HDMI 2.2, offering increased bandwidth and advanced features, understanding your TV’s port capabilities will become even more crucial for maximizing your home entertainment experience.
