How to Disable LG OLED Auto-Dimming (TPC & GSR) – Stop Your Screen from Dimming

Quick answer: On supported pre‑2023 LG OLEDs you can turn off auto‑dimming by disabling two protections in the service menu — TPC (also called ASBL) and GSR. Use a service remote or an advanced control app to access the menu, then set “TPC Enable” and “GSR Enable” to Off. Newer 2023+ models (e.g., C3/G3) restrict these toggles for consumers.

Introduction

If your LG OLED dims during static scenes, menus, or long gaming sessions, you’re running into the panel’s auto‑dimming protections. These systems are great for longevity, but they can be distracting — especially for calibrators, content creators, and competitive gamers. This guide shows how power users disable auto‑dimming safely, when it’s not possible, and which alternatives minimize dimming without risking burn‑in.

What Are TPC and GSR?

• TPC (also known as ASBL) stands for Temporal Peak Luminance Control. It lowers overall screen brightness after prolonged static content to protect the panel.
• GSR (Global Sticky Reduction) reduces brightness in areas with static elements such as channel logos or HUDs.

Learn the fundamentals in the glossary: ASBL/TPC and GSR. For an overview of all protection features, see LG OLED Protection Features (TPC, GSR, Logo Luminance).

Note: “Logo Luminance” is separate. It specifically targets detected logos and can be adjusted from regular settings without the service menu.

Service Menu Access (Pre‑2023)

On 2018–2022 models, TPC and GSR are typically accessible in the hidden service menu. You can enter it with a physical service remote (or an equivalent app) and the common access code “0413.” Exact paths vary by model/firmware.

Safety first:

• Make small, documented changes only. Write down defaults before edits.
• Service menu changes can void warranty or increase burn‑in risk.
• Ensure good ventilation and avoid high, sustained full‑screen brightness.

Tools that can help:

• Oled Control app: provides streamlined toggles for TPC/GSR on supported models and firmware.
• Traditional service remote + IR blaster: reliable for older sets.

How to Disable Auto‑Dimming (TPC & GSR)

These paths differ by model, but the flow looks like this:

1. Open the Service Menu using a service remote (code “0413”).
2. Navigate to the OLED/Panel or Control section.
3. Locate “TPC Enable” and set to Off.
4. Locate “GSR Enable” and set to Off.
5. Save changes and power‑cycle the TV.
6. Verify using bright, static content for several minutes.

With Oled Control (when supported):

1. Connect the app to your TV on the same network.
2. Open Premium features and locate Auto‑Dimming controls.
3. Toggle TPC and GSR Off, then apply.
4. Test and monitor temperature/brightness stability.

Important Limitation on 2023+ Models (C3/G3)

Starting with many 2023 models (C3/G3 and newer firmware), LG removed consumer access to disabling TPC/GSR in the service menu. This is to better protect panels against long‑term image retention and burn‑in. Only authorized service partnerships may have access.

What you can do instead:

• Use less aggressive energy saving and reduce static elements.
• Prefer dynamic content and enable Screen Shift / Logo Luminance Adjustment.
• Use higher peak brightness only for short sessions.
• Calibrate HDR tone mapping to avoid unnecessarily high full‑field APL.

Risk, Warranty, and Best Practices

Disabling protections increases risk of temporary retention and permanent burn‑in. To reduce risk:

• Keep ambient temperature cool and the TV well‑ventilated.
• Avoid long, static full‑screen images. Use screensavers during breaks.
• Monitor for tint shifts, unusual heat, or brightness instability.
• Re‑enable protections immediately if you notice issues.

Dimming Workarounds If You Can’t Disable It

• Use brighter HDR picture modes or adjust gamma/peak brightness conservatively.
• Nudge small on‑screen movements (mouse, HUD toggle) to reset TPC timers.
• Reduce static elements: hide taskbar/dock, minimize persistent overlays.
• Keep Logo Luminance at Low/Medium as a safer alternative to full disable.

FAQ

Is it safe to disable TPC/GSR?

It’s safe for short, controlled sessions if you understand the risks and watch panel temperature. For general viewing, keep protections on.

Why did my 2023 LG TV remove the option?

LG tightened protections to reduce burn‑in exposure for typical consumers. Only partnered workflows may allow overrides.

Does Oled Control work on my model?

Oled Control supports many 2018–2022 models. Some 2023+ firmwares restrict these toggles. Check app release notes for current compatibility.
