What is the difference between OLED and AMOLED dark mode?

AMOLED is a specific type of OLED display. Both technologies benefit from absolute black backgrounds by turning off pixels, but both look equally harsh on desktop LCD screens.

Can I keep AMOLED dark mode on my phone while using gray on desktop?

Yes. GPT Master is a desktop browser extension, so it will only change the theme on your computer. Your mobile ChatGPT app will keep its default dark theme.

Does this override affect the sidebar or prompt formatting?

No. The extension only targets the background colors. Your folders, text styling, and prompt lists remain completely untouched.

How to manage ChatGPT AMOLED dark mode on desktop

Updated June 15, 2026

Quick answer

ChatGPT uses an AMOLED dark mode that renders page elements in absolute black to conserve battery on mobile devices. That trick helps on phones, but it backfires on desktop LCD monitors where pixels cannot turn off. Most browser extensions cannot selectively disable the theme without breaking other page elements. GPT Master resolves this by stripping the AMOLED styling code and restoring the original soft-gray dark theme.

AMOLED displays save power by turning off black pixels completely. However, desktop monitors use backlights that stay on even when displaying black, meaning the AMOLED layout provides no power savings on a computer. Instead, it only introduces high contrast that makes reading uncomfortable.
