How to enable HDR on LG HDMI TV

You should know that when you turn on HDR, you must turn off all additional picture enhancement programs in your TVs, this happens automatically. If the HDMI port is set to HDR, all additional picture enhancement programs will be disabled. Therefore, HDR is only set for the currently active HDMI input. If you set HDR to HDMI1, HDR will not work on the other HDMI ports.

HDR (High Dynamic Range) is an addition to existing digital video formats: it is not a new digital video technology, but simply adds metadata to the existing video encoding standards, metadata that controls the settings of your TV. The picture on the screen of your LG TV using metadata becomes more “live” and natural. But you should know that HDR only works on high-end TVs with displays capable of displaying over a billion colors in 10-bit color depth. HDR – uses a color palette based on the use of 10-bit gradation. Thanks to it the viewer can see the subtle nuances of colors that were not previously available.

Many of LG’s current TV models are equipped with the ability to support the HDR standard. HDR technology is supported on LG TVs since 2016. These TVs are OLED, Super UHD, NanoCell, and QNED lines. They support all major HDR formats. You can find out if your model supports HDR format in the user manual or other TV documents.

Which HDR standards do LG TVs support?

LG TVs support the following HDR formats:

  • Dolby Vision – The format supports 12-bit color coding, so the picture looks as realistic as possible, using metadata to change settings during viewing down to the frame. But existing televisions cannot show the full available range of colors transmitted by this standard. The standard is designed with a large margin for the future. Metadata can be at the frame level.
  • HDR10 – the first format, a feature, the dynamic range was set for the whole movie, when you start watching, the format is a little outdated.
  • HLG – simplified format was developed for television broadcasts, has no metadata, dynamic range data is sent along with the signal. According to Wikipedia, it is used for BBC iPlayer, DirecTV, Freeview Play, and YouTube broadcasts.
  • Dynamic Tone Mapping Pro is an HDR10+ standard, but LG is embarrassed to state it in the specs, HDR10+ is a Samsunng development. So using the name Dynamic Tone Mapping is the essence of HDR10+, added metadata to dynamically change settings.

Enable HDR in LG TV settings

You should know TVs have many features and additional video processing programs, and these programs can negatively affect HDR video viewing. Therefore, HDR is disabled by default on LG TVs. To watch HDR content on your LG TV, you need to activate this feature. It is very simple. To enable HDR, do the following:

Select “Home” from the TV menu.
Find the HDMI section.
Go to the “Settings” section.
Select the “Advanced” section.
Locate the “Picture” option.
Select HDMI ULTRA DEEP COLOR.
Activate it by moving it to the “On” position.
Press Restart.

Settings for LG’s 2017-2022 OLED TVs in addition to HDR settings

The 2017-2022 OLED models will also need to activate Dynamic Tone Mapping, which includes an HDR10+ metadata processing program. If you don’t do this, the TV will not fully accept HDR. If you adjust the picture while on one of the HDMI inputs, you are interacting with a profile exclusively for that input. Remember that there can be two profiles: HDR and SDR. Therefore, to adjust the HDR profile, you will need to run HDR content (it can be a movie, TV series or game) on your LG TV. Why only OLEDs need to have Dynamic Tone Mapping turned on is because of the nature of OLED displays they age and the higher the brightness of the picture the faster the display ages. That is why all settings that affect the brightness of the image are disabled by default.

Calibrating your LG TV for HDR content

Calibration helps you accurately adjust the HDR display. Before you start the calibration, run any HDR video content on your TV.

  • Under “Picture”, select HDR Technicolor Expert.
  • In the picture settings, select:
  • Energy Saving / Eye Comfort – Off.
    • OLED Light – 100.
    • Contrast – 100.
    • Brightness – 50.
    • Sharpness – 10.
    • Color – 55.
    • Tint – 1.
  • In the “Expert Settings” select:
    • Dynamic Contrast – Low.
    • Super Resolution – Off.
    • Color Gamut – Auto.
    • Color Filter – Off.
  • In the “White Settings”, select Warm2 mode.
    • Select Noise Reduction – Off:
    • Noise Reduction – Off.
    • MPEG Noise Reduction – Off.
    • Motion Eye Care – Off.
    • TruMotion – On (De-Judder: 0 / De-Blur: 0).

The last option is especially important for owners of LG OLED TVs, because otherwise there is a chance that the image will start to flicker. This is because due to the 120 Hz refresh rate, movies at 24 frames per second do not always display well. The TruMotion function interpolates the frames to make the image smoother. The rest of the settings should be set to 0.

LG’s 2018-2020 OLED TVs also have a TruMotion Pro mode, aka Black Frame Insertion, which is able to forcibly lower the frequency from 120 to 60 Hz by adding a black frame once per second to the image.

Also, depending on the LG TV model, settings may include Edge Enhancer (if this option is available, it should be left on) and Gamma (if this option is available, it should be set to 2.2).

Do I need to set the HDR type on my LG TV?

No, you do not need to, the TV receives content with HDR data itself determines what format they are and automatically begins to recognize them if HDR is enabled on this port HDMI.
