The Steam Deck is much more than a portable Steam console. It is a Linux desktop PC, a configurable controller, a Remote Play client, a dockable living-room computer, and a surprisingly capable travel machine. The important qualification is that “can do” does not always mean “works perfectly”: Windows software may depend on Proton, launchers, codecs, drivers, or game-specific compatibility.
Start with the built-in features below before buying accessories or installing community tools. Most of the Deck’s best capabilities require only a few menu changes.

The five features to try first
- Hold the Steam button to display the current shortcut list. This is the most reliable way to check shortcuts on your installed SteamOS version.
- Press Steam + X to open the on-screen keyboard.
- Open Steam → Power → Switch to Desktop to enter the KDE Plasma desktop.
- Customize a game’s controls through its Library page and the gamepad icon.
- Format a storage card through Steam → Settings → System → Format SD Card.
SteamOS labels can change between releases, so treat the paths in this guide as current reference points rather than permanent interface guarantees. Valve’s basic-use guide is the best place to confirm a shortcut or menu label.
1. Use the Steam Deck as a Linux desktop
Desktop Mode is not a hidden developer mode. It is the normal KDE Plasma desktop included with SteamOS, which is Arch-based. Switch to it with Steam → Power → Switch to Desktop.

You can browse the web, manage files, download software, play media, use web apps, communicate, work in a terminal, and install Linux-compatible applications through the Discover software center. The Deck can also run software outside Steam and add applications to Steam as non-Steam games so they can be launched from Gaming Mode.
Without a mouse, the right trackpad moves the pointer, R2 acts as left-click, and L2 acts as right-click. The touchscreen handles tapping and scrolling, while Steam + X provides the on-screen keyboard.
Desktop Mode is useful for file management, mod tools, emulators, remote-access applications, programming, and alternative game launchers. But it is still Linux. A program may require a native Linux build, a Flatpak package, Proton, another compatibility layer, manual configuration, or a separate operating-system installation. Installing a shortcut does not make an application officially supported or controller-friendly.

2. Turn the controls into a programmable input system
The Deck has two haptic trackpads, a six-axis gyro, capacitive thumbsticks, a touchscreen, analog triggers, and four assignable rear grip buttons. Steam Input lets you use these controls on a per-game basis rather than accepting one fixed controller layout. Valve lists the hardware details on its Steam Deck hardware page.
From the Library, highlight a game, open its details, select the gamepad icon, and choose the current layout to edit it. To browse community configurations, select the current template and move to Community Layouts with R1.
Useful layouts
- Turn a trackpad into a mouse for strategy games, shooters, inventory screens, or desktop software.
- Activate gyro aiming only while touching a stick or trackpad.
- Place reload, crouch, map, jump, or push-to-talk commands on the rear buttons.
- Create radial menus for weapons, spells, emotes, or shortcuts.
- Use mode shifts so one button changes what another control does.
- Map keyboard commands to games with incomplete controller support.
- Save separate handheld and docked layouts.
Community layouts vary in quality, and a layout that mixes gamepad and keyboard inputs can affect prompts or matchmaking. Save a known-good configuration before experimenting. If an input seems broken, test the hardware through Steam → Settings → Controller → Test Controller Inputs.
3. Use the Deck as a controller for another PC
Through Steam Remote Play, the Deck can serve as the control surface while another PC performs the game’s rendering. This is useful when the host computer is connected to a TV, when you want trackpads or gyro controls, or when a game runs poorly on the Deck but well on the PC. Valve confirms this controller use in its Steam Deck FAQ.
The host PC must be powered on and reachable over the network. A wired Ethernet connection for the host is preferable. Because the Deck is communicating through a streaming session, it will not behave exactly like a directly wired controller: video, audio, and input all depend on network quality, and latency can be noticeable.
4. Stream demanding games from a more powerful PC
In local play, the Deck renders the game. In Remote Play, the host PC renders it, sends video and audio to the Deck, and receives your input. That makes Remote Play different from cloud gaming, where a commercial remote server runs the game.
Remote Play is especially useful for demanding modern games, ray-traced titles, games already installed on a desktop, or lighter sessions where you want to reduce the Deck’s workload. It works best on a strong home network and is generally more forgiving for single-player or slower-paced games than competitive games.
Common problems include Wi-Fi congestion, a sleeping host PC, mismatched resolution or refresh-rate settings, audio being sent to the wrong device, launcher failures, and input lag. If the stream is poor, test the host on Ethernet, reduce the stream quality, check the host’s power settings, and compare the experience with local rendering.

Remote Play cannot overcome a weak host PC. It changes where the game is rendered; it does not make that computer faster.

5. Turn it into a docked PC or console
The USB-C port supports charging, external displays, peripherals, hubs, and compatible storage. You can connect a monitor or TV, keyboard, mouse, Ethernet, controllers, USB storage, and audio devices. A dock behaves much like a USB-C hub connected to a PC.
- Connect the display, peripherals, network cable, and charger to the dock or hub.
- Connect the Deck to the dock.
- Wait for the display to appear.
- If necessary, use Desktop Mode to adjust resolution, refresh rate, and audio output.
Docking does not increase the Deck’s processing power. Valve describes the Deck as running at full performance in portable mode; the dock adds ports and display connectivity, not a faster GPU.
Valve’s current specifications list USB-C DisplayPort output up to 8K at 60Hz or 4K at 120Hz, subject to the display, cable, dock or hub, and configuration. This is an output capability, not a promise that games will render natively at those resolutions or frame rates.

For 5.1 or 7.1 audio over HDMI or DisplayPort, switch to Desktop Mode, click the speaker icon, find the HDMI/DisplayPort output, open its three-line menu, and select the desired channel count. The exact output labels can vary by setup.
If the docked display fails
- Unplug power from both the dock and Deck for a full reset; unplugging only the dock may leave it powered by the Deck.
- Try another HDMI or DisplayPort cable and confirm the display’s input.
- Remove peripherals one at a time to find conflicts.
- Update SteamOS and dock firmware where available.
- Test the display through another hub or adapter.
- Remember that unusual monitor, peripheral, and multi-display combinations may not be universally supported.
Valve’s docking guide contains the current troubleshooting advice.
6. Expand storage with a microSD card
Every Steam Deck model supports microSD expansion. SteamOS formats the card as ext4 with casefolding and supports UHS-I cards. Faster UHS-II and UHS-III cards may function, but the Deck does not use their higher transfer speeds.
Rank #4
- 512 GB NVMe SSD: Fast storage for quicker game load times and space for larger game libraries.
- OLED Display: 1200x800 resolution with deep contrasts and vibrant colors for a captivating visual experience.
- Custom AMD APU: Power-efficient Zen 2 CPU and RDNA 2 GPU for desktop-level gaming performance.
- Expandable Storage: Add more space with a microSD card slot, ensuring you can bring even more games with you.
- Versatile Controls: With built-in thumbsticks, trackpads, and touchscreen controls, you have full control over your gaming experience.
- Insert the card.
- Open Steam → Settings → System.
- Select Format SD Card.
- Confirm and wait for the process to finish.
Formatting erases the card. A Deck-formatted card is not normally plug-and-play on Windows without additional software, so do not use it as a casual shuttle between the Deck and a Windows PC. Never remove it during active downloads or while games are using it. Counterfeit or low-quality cards can cause failed installations and corrupted data.

MicroSD is the simplest expansion option. An internal SSD upgrade can provide faster internal storage and a single-library setup, but it requires backups, careful disassembly, and a willingness to treat the job as hardware repair.
7. Install software and games outside Steam
There are three broad routes:
- Linux-native software: usually the cleanest option when available.
- Discover and Flatpak applications: convenient, though sandbox permissions can limit access to drives, folders, controllers, or game files.
- Non-Steam shortcuts: useful for launching installed applications from Gaming Mode, but not proof of compatibility.
Windows games often run through Proton, Valve’s compatibility layer. “Playable” is not the same as native Linux, and a game can start while still having broken cutscenes, text input, multiplayer, launchers, or controller support. Anti-cheat systems, codecs, middleware, patches, and external services remain game-specific. Valve’s SteamOS information describes the Linux and Proton foundation, but it does not mean every Windows application will work.
Emulators and legally obtained backups are another possible Desktop Mode use, subject to the laws that apply where you live. Community launchers, plugins, compatibility utilities, and installation scripts can change or break after SteamOS updates, so treat them as optional maintenance projects rather than built-in Deck features.

An installed game can generally work offline when the game itself does not require an internet connection. Before traveling, connect to the internet, launch the game once, complete any launcher or DRM checks, switch Steam to Offline Mode while still connected, and test it before leaving.
Offline play can fail because of always-online authentication, external launchers, server-side progression, matchmaking, cloud-only saves, DRM checks, or recently changed account credentials. Download updates and required content in advance, and do not assume every game will work on a plane.
Best Value
- Valve is entering the gaming console marketplace with the new Steam Deck, a console geared towards PC gamers. The Steam Deck can be docked to a monitor, and used as a PC, or docked to a TV.
- Players can play a huge variety of games at any time with the comfort of a console and the freedom of a PC. Not anti-glare screen.
- Like the name suggests, the Steam Deck will include upgraded 1TB storage, and will include a carrying case. A micro SD slot will also enable expanded storage.
- Valve partnered with AMD to create a specialized APU optimized for handheld gaming, and Valve says the chip will deliver performance to run AAA gaming titles.
- The Steam Deck is outfitted with a 7-inch touchscreen, and two trackpads under the control sticks that allow gamers to operate games never designed outside of mouse and keyboard capabilities.
9. Use it as a lightweight general-purpose computer
The Deck can handle browsing, email, writing, media playback, file organization, remote access, basic programming, terminal work, and browser-based work environments. It can even be a useful emergency or travel PC when connected to a TV.
The limitation is ergonomics. For sustained desktop work, a keyboard, mouse, monitor, stand, and dock or USB-C hub make a much bigger difference than software tweaks. The controls are clever enough for occasional file management or couch browsing, but they are not a replacement for a proper desk setup.
10. Recover a broken installation safely
Use the least destructive fix first:
- Restart: a normal reboot for temporary problems.
- Update: install available SteamOS and firmware updates.
- Remove recent additions: disable third-party applications or plugins if the trouble began after installing one.
- Factory reset: erases user data through the normal interface.
- Recovery environment: use Valve’s recovery tools when Gaming Mode cannot load.
- Full reimage: a destructive reinstall and last resort.
Back up saves, screenshots, configuration files, and Desktop Mode data first. Cloud saves do not cover every local file. Recovery can remove installed applications and customizations, and some procedures require recovery media and a USB-C adapter. Follow Valve’s current SteamOS recovery instructions instead of relying on an old command or video.

The OLED model is not a fundamentally faster gaming machine. Its advantages are the display, battery, wireless hardware, and efficiency; the same compatibility, dock, Proton, and desktop caveats still apply. Confirm model-specific features such as Bluetooth-controller wake against the SteamOS release installed on your device. See Valve’s OLED specifications and LCD specifications for current details.
What should you buy?
Buy accessories for a real use case, not because every Deck guide lists them:
- Buy nothing first: explore Steam Input and Desktop Mode.
- Add a reputable UHS-I microSD card: the simplest way to expand a game library.
- Add a USB-C hub or dock: only if you regularly use a TV, monitor, Ethernet, or several peripherals.
- Add a keyboard, mouse, or stand: if Desktop Mode will be part of your routine.
- Consider an SSD replacement: only when you have a clear capacity or storage-performance reason and are comfortable with repair work.
The official dock is not the only viable option. Compare hubs and docks by ports, USB-C Power Delivery passthrough, display support, Ethernet, firmware support, warranty, and the peripherals you actually own. Avoid paying for UHS-II or UHS-III microSD speeds the Deck cannot fully exploit.
