TVs keep getting thinner and their speakers smaller. That is why it is so common not to understand the dialogue, to keep turning the volume up and down or to notice lag with headphones. These settings fix almost all of it.
1. Dialogue you cannot make out
Films and series are mixed with cinemas full of speakers in mind. On the TV’s speakers, voices end up buried under the music and effects. And on thin TVs it is worse: the speakers are small and often face downwards or backwards, not towards you.
- Turn on voice enhancement: LG calls it Clear Voice; Sony, Voice Zoom; other brands call it “clear voice” or “dialogue”, depending on the model.
- Try night mode (or reduced “dynamic range”): it brings the volume of whispers and explosions closer together.
- If nothing works, a soundbar with a centre channel makes a real difference, because the voices come out of it.
2. A soundbar with a single cable: eARC
With HDMI eARC, the TV sends the sound to the soundbar over the same HDMI cable and you control the volume with the TV remote. Unlike the older ARC or an optical cable, it supports high-quality formats such as Dolby Atmos or DTS:X.
3. A single remote: HDMI-CEC
HDMI-CEC lets the TV remote control whatever you have connected over HDMI: a TV box, a soundbar or a console. What is more, when you switch the device on, the TV turns on and changes to the right input by itself.
| Brand | HDMI-CEC name |
|---|---|
| Samsung | Anynet+ |
| LG | SimpLink |
| Sony | BRAVIA Sync |
| Philips | EasyLink |
| Panasonic | VIERA Link |
Turn it on in the TV settings (it is usually under “External devices” or “HDMI”) and, on the TV box, in its display or HDMI settings.
4. Bluetooth headphones with lag
Bluetooth compresses and transmits the sound, and that adds a small delay that is noticeable on a TV: the voice lags behind the lips.
- Look in the TV’s sound settings for audio sync or “audio delay” and adjust it.
- Many players also let you move the sound earlier or later from within the player itself.
- If you use them often, headphones with their own transmitter connected to the TV usually have less lag.
5. Does one particular channel sound bad?
If the problem is with one channel or film and not the rest, try another audio track from the player. We explain it in IPTV with no sound or a black screen.
Frequently asked questions
Do I need a special cable for eARC?
A High Speed with Ethernet HDMI cable or an Ultra High Speed one will do. We explain it in which HDMI cable to buy.
Does HDMI-CEC work between different brands?
Usually yes, although some features may vary. Turn it on on both devices.
Does night mode lower the quality?
It reduces the difference in volume, not the sound quality. It is ideal for listening at low volume.
