HGiG on LG OLED: HDR Gaming Calibration Explained

Quick Answer

HGiG is industry guidance for coordinating HDR games, platforms and displays. On compatible LG gaming picture modes, selecting HGiG asks the TV to avoid adding its usual dynamic tone mapping above the display's usable range. You then calibrate the console, Windows PC or game for that presentation.

HGiG is not an HDR format, certification of every game, or a switch found on every source. A poorly configured game can still look wrong.

Correct setup order

Put the TV in its low-latency gaming picture mode.

Select HGiG on the TV if the active model, signal and mode expose it.

Run the source calibration: PS5 Adjust HDR, Xbox HDR Game Calibration or Windows HDR Calibration.

Configure the game's own HDR controls only after the system step.

Recalibrate if you change the TV's tone-mapping mode.

This order reduces “double tone mapping,” where both the source and TV compress highlights independently.

HGiG or Dynamic Tone Mapping?

Use HGiG when you want a repeatable source-led calibration and the game supports useful HDR controls. Try Dynamic Tone Mapping when you knowingly prefer a brighter adaptation, especially in a lit room. That is a viewing preference, not proof that one mode is universally correct.

Dolby Vision gaming follows a different processing path. Do not assume the HDR10 HGiG selection controls Dolby Vision output in the same way. Menus also vary by model year and firmware.

The responsibility chain

HGiG guidance separates three jobs. The display communicates or is calibrated for its usable HDR range. The platform exposes a calibration step. The game renders highlights and UI for that target. The purpose is to avoid a second unpredictable compression pass in the television after the game has already mapped its image.

This is guidance, not a mandatory certification. Games can ignore system settings, provide their own peak/paper-white controls or implement HDR poorly.

Platform workflows

On PS5, select HGiG on the LG before using Adjust HDR. Follow Sony's visible-symbol instructions rather than copied click counts. On Xbox, verify 4K TV Details and run HDR Game Calibration. On Windows, establish the final HDR display path and run Windows HDR Calibration; Auto HDR and native HDR titles remain different renderers.

After system calibration, open the game's controls. Peak Brightness generally concerns highlight range; Paper White commonly affects normal scene/UI brightness. Follow title documentation because labels differ.

Diagnosing “HGiG is too dark”

First confirm HDR and Game Optimizer are active. Reset copied Black Stabilizer, color and white balance changes. Verify RGB range. Then recalibrate in HGiG. Compare a second known game.

If only one title remains dark, its implementation is the likely limit. If every title is washed out, range or HDR state is more plausible. If the room is bright, reflection can hide the intended shadow/midtone presentation.

Dynamic Tone Mapping On can raise visibility adaptively. Choose it openly when preferred, but it changes the calibration target. Re-run source/game setup after a permanent switch.

Model and format limits

C1/G1 and C2/G2 expose HGiG within supported HDR Game Optimizer contexts. A grayed control can reflect the active signal or mode. Dolby Vision gaming is separate; do not search for HGiG inside its processing path.

HGiG does not enable HDR, 120 Hz, VRR or ALLM. Those must be negotiated independently by source and HDMI chain.

HGiG FAQ

Does HGiG cap brightness?

It asks the TV to avoid extra dynamic remapping above the calibrated display target. Actual output still depends on the panel/mode.

Is it always more accurate?

It provides a repeatable chain when the game follows the guidance. Noncompliant games can still look wrong.

Why do fixed click-count guides disagree?

They assume a panel, firmware and clipping point. On-screen calibration after selecting the final mode is more defensible.

Should HGiG be used for movies?

No. It is an HDR gaming workflow; HDR10 films use their movie-mode tone mapping and Dolby Vision uses its own path.

Practical PS5 example

Set the LG to HDR Game Optimizer and select HGiG while an HDR signal is active. Open PS5 Adjust HDR and follow the symbol until it is barely invisible as Sony instructs. Do not count clicks from another C1 or G2. Launch a game that uses system calibration, then set its own paper-white control only if provided.

If the result is dark, confirm RGB range and that the game did not silently use SDR. Compare a second title before changing the TV.

Practical Xbox and PC examples

Xbox 4K TV Details verifies the chain before HDR Game Calibration. A receiver can change advertised capability, so direct connection is the baseline. Windows requires HDR active on the intended display and Windows HDR Calibration after final tone-map selection. Auto HDR for an SDR game is not equivalent to native HDR authoring.

When DTM is the better personal choice

In an uncontrolled bright room, HGiG's repeatable mapping may be hard to see through reflections. Dynamic Tone Mapping can be preferable for playability. Describe it as an intentional adaptation, recalibrate where appropriate and do not present the brighter image as automatically containing more correct detail.

What HGiG cannot solve

It cannot remove VRR flicker, increase frame rate, repair HDMI blackouts, correct a Full/Limited mismatch or restore source detail. Those symptoms belong to timing, transport or level mapping. It also cannot make an OLED panel reproduce highlights above its physical capability; it organizes where the source should place those highlights.

If a game has no functional HDR controls and ignores system calibration, HGiG may provide no practical advantage. Use a well-implemented reference title before judging the television.
