Steam Deck Refresh Rate: LCD vs. OLED Explained

Short answer: The current Steam Deck LCD display supports up to 60Hz, while current Steam Deck OLED models support up to 90Hz. There is no single refresh-rate number for every Steam Deck because the built-in display depends on the model, while an external display has its own resolution and refresh-rate limits.

Refresh rate is the number of times a display can update each second. It is not the same as frames per second (FPS), and it does not guarantee that a game will render at the display's maximum. Valve's official LCD and OLED comparison lists the LCD at up to 60Hz and OLED models at up to 90Hz. Specifications and available modes can change with hardware, display and software.

Steam Deck refresh rate by model

Use these figures as model-specific display ceilings, not as promises that every game will reach the number shown.

Use case	Current display or output ceiling	How to interpret it
Steam Deck LCD handheld screen	Up to 60Hz	The built-in LCD can refresh up to 60 times per second.
Steam Deck OLED handheld screen	Up to 90Hz	Valve's current technical page lists a 7.4-inch, 1280x800 HDR OLED display with a refresh rate of up to 90Hz.
OLED external display over DisplayPort through USB-C	Up to 8K at 60Hz or 4K at 120Hz, as listed by Valve	This is an output specification, not a guarantee that a particular game, display, dock or cable will expose or sustain that mode.

The OLED and LCD numbers describe the built-in screens. When the Deck sends a signal to a monitor or TV, the connected display and the selected resolution become part of the limit.

Refresh rate, FPS and frame caps

Refresh rate, measured in hertz (Hz), describes how often the screen can update. FPS describes how many frames the game is rendering. A 90Hz OLED screen can accept up to 90 display updates per second, but it does not force a game to produce 90 FPS. Likewise, a 60Hz LCD can display fewer than 60 frames per second if the game or settings cannot maintain that rate.

A higher refresh-rate setting can make motion look smoother when the game is producing enough frames, but it does not add CPU or GPU performance.
A frame-rate cap sets a maximum target for the game or system. Choosing a rate the game can hold consistently can improve frame pacing, but a cap cannot create performance that the hardware or game does not have.
Refresh-rate and frame-cap changes can affect the overall workload, but battery results are not universal. Game demand, brightness, resolution, frame cap, software and the connected display all matter.

Handheld versus external display

In handheld mode, the built-in LCD or OLED panel determines the available refresh-rate ceiling. In external-display mode, the monitor or TV, dock or adapter, cable, resolution and software all affect which modes are available.

Valve's current OLED technical specifications list DisplayPort-over-USB-C output up to 8K at 60Hz or 4K at 120Hz. That listing describes the output capability for the specified connection; it does not mean every game will render at 120 FPS, and it should not be applied automatically to every Deck, dock or display setup.

Practical settings for current Steam Deck owners

For handheld play

Identify the built-in display first. Treat 60Hz as the upper limit for an LCD model and 90Hz as the upper limit for an OLED model.
Set the frame cap to a rate the game can maintain reliably. If an OLED game cannot hold 90 FPS, a lower stable target may provide more consistent pacing without changing the display's maximum.
Open the Steam button menu and review the Performance controls for refresh rate and frame limit when those controls are available in the current SteamOS version. Menu wording and available modes can change with software.

For a monitor or TV

Check the display's supported refresh rates at the resolution you want to use. A display may support a high refresh rate at one resolution but not another.
Check the complete connection path, including the dock or adapter and cable, before treating a listed external mode as available.
Match the external refresh setting with a frame-rate target the game can actually deliver. An external 120Hz mode is not the same thing as guaranteed 120 FPS gameplay.

Bottom line

If you mean the built-in screen, the current Steam Deck LCD reaches up to 60Hz and current OLED models reach up to 90Hz. If you mean an external monitor or TV, the available ceiling depends on the connection, resolution, display and software. Treat refresh rate as a display capability and frame caps as a tuning control, then choose the mode the model and display support and the game can sustain consistently.
