Connecting your devices to a TV with HDMI is usually straightforward. Plug in the cable, and you’re good to go, right? Not quite. Getting the best possible performance from your television requires a bit more attention to detail than simply plugging things in.
Over the years, a few HDMI tweaks have made a noticeable difference in picture and sound quality. These aren’t necessarily about buying the most expensive cables, but rather understanding how to optimize the connections you already have.
1. Choose the Right HDMI Port
When setting up your TV and connected devices – a PlayStation 5, a Blu-ray player, a soundbar – it’s easy to assume all HDMI ports are created equal. That’s rarely the case. Some ports support higher specifications, like HDMI 2.1 for high refresh rates, while others are designated for ARC/eARC (Audio Return Channel) for soundbars and receivers. Using the correct port for each device is crucial for maximizing video and audio quality.
To identify the best port for each device, look for labels indicating support for features like “4K 120Hz,” “8K,” or “HDMI 2.1.” If no such labels are present, the ports are likely standard HDMI 2.0. When in doubt, consult your TV’s user manual. HDMI 2.1 ports support higher resolutions and frame rates, unlocking advanced features like Variable Refresh Rate (VRR). The port labeled ARC/eARC should be used for your soundbar or home theater receiver. EARC, the newer standard, supports uncompressed, high-bitrate audio formats like Dolby Atmos and DTS:X.
Reserve HDMI 2.0 ports for less demanding devices like streaming sticks and cable boxes, freeing up the HDMI 2.1 ports for devices that benefit from increased bandwidth.
2. Use High-Speed HDMI Cables
The quality of your HDMI cable matters. If you’re still using an older cable, it might not be handling 4K HDR streams as effectively as a newer one. You don’t need to spend a fortune, but a certified, high-quality cable with the right specifications is essential. Look for labels like “high speed,” “premium high speed,” or “ultra high speed” on the packaging or cable itself.
For devices like gaming consoles and Blu-ray players, an “ultra high-speed” HDMI cable (48Gbps, HDMI 2.1) is recommended, supporting features like 4K, 8K, HDR, and Dolby Vision. For devices supporting up to 4K at 60Hz, a “premium high-speed” HDMI cable (18Gbps, HDMI 2.0) is sufficient. Keep cable lengths under 10 feet (3 meters) for 4K signals; for longer runs, consider an optical HDMI cable.
3. Enable Enhanced HDMI Features
Many TVs have individual settings for each HDMI input that can significantly impact performance. These settings, often labeled as “HDMI Ultra HD Deep Color” (LG), “Input Signal Plus” or “HDMI UHD Color” (Samsung), or “Enhanced Format” (Sony), need to be enabled to unlock the full potential of your devices. These settings allow the TV to accept a wider range of signals and color depths.
4. Choose a Picture Mode for Inputs
TVs offer various picture modes – Game, PC, Cinema, Filmmaker, Sports, Vivid – each optimized for different content and devices. Selecting the appropriate mode can dramatically improve your viewing experience. For example, enabling Game Mode reduces input lag, making gameplay more responsive. Filmmaker Mode provides more natural and accurate colors, preserving the director’s intent. Most TVs remember the picture mode per HDMI input, allowing you to customize settings for each connected device.
5. Turn On Features Like ALLM and VRR
For gamers, Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) are essential features. ALLM automatically activates Game Mode when a console is detected, eliminating the need for manual switching. VRR matches the TV’s refresh rate to the game’s frame rate, reducing screen tearing and stuttering. Ensure both your TV and console have these features enabled in their respective settings.
6. Use ARC/eARC for Audio
Connecting your soundbar to the HDMI port labeled “ARC” or “eARC” allows the TV to pass all its audio to the soundbar, regardless of the source. EARC, the upgraded version, supports uncompressed surround sound and lossless audio formats like Dolby Atmos and DTS:X, delivering a more immersive audio experience.
7. Keep Your Ports and Cables Clean
Dust and grime can accumulate in HDMI ports and on cable connectors, leading to poor contact and signal issues. Regularly clean your ports with compressed air and a soft brush. Gently wipe cable connectors with a lint-free cloth dampened with isopropyl alcohol. Avoid sharply bending or crimping HDMI cables, and consider using right-angle adapters or swivel heads to reduce strain.
8. Update Your TV and Devices
Keep your TV and connected devices updated with the latest firmware. Updates often include bug fixes, performance improvements, and support for new features. Most smart TVs can automatically update via the internet. Check your TV’s settings menu for a Software Update or Firmware Update option and update your consoles and streaming devices regularly.
