Valve’s Steam Deck revolutionized PC gaming when it came out in 2022, popularizing the handheld gaming PC format. In 2026, it’s still got a great performance-to-price ratio, and is plenty relevant compared to more expensive and more finicky alternatives like the Asus Rog Xbox Ally X. But that doesn’t mean it’s fully stacked right out of the box. SteamOS presents a more intuitive pick-up-and-play experience than I’ve used on any other handheld gaming PC (or gaming PC in general, to be honest), but there are plenty of hacks and customizations you can use to make it truly yours.
Steam Deck’s desktop mode basically turns it into a mini PC
This one’s simple, but vastly increases what you can do with your Steam Deck. Yes, the Steam Deck’s biggest strength is that you can easily hop into games right from the home screen using the built-in controls, but did you know that you can also use it like a more traditional desktop?
To swap the device over to its built-in desktop mode, press the Steam button (the one on the device itself), then select Power. From there, select Switch to Desktop.
Bam, you’ll be taken right to a more traditional PC interface, and one that will look extra familiar to you if you’ve ever used Linux, the base operating system SteamOS is built on.
You’ll need desktop mode to enable a lot of the other hacks on this list, but it’s also great on its own. With it, you can install your favorite Linux productivity apps, or even just browse the web using Microsoft Edge, which comes pre-installed (you can install your browser of choice later). You can use the right trackpad, the thumbsticks, or the touchscreen to move the mouse cursor, and press Steam + X to bring up a keyboard, but you can also plug in an external accessory or dock using the USB-C port on top of the device, too. Play this right, and you can basically turn the Steam Deck into a full-fledged Mini PC, complete with a built-in screen.
To leave desktop mode and re-enter the Steam Deck’s default interface, click on the Return to Gaming mode icon in your desktop’s top left corner.
You can play games that aren’t from Steam
By default, the Steam Deck will show you games from your Steam Library, and that’s where the Store page will take you, too. That makes sense—Valve wants you to buy games from its store. But because the Steam Deck is essentially just a highly specialized mini PC, it won’t stop you from playing games from other PC gaming stores.
There are a few ways to do this, but by far, the most convenient one is Heroic Launcher. This allows you to install games from your Epic Game Store, Amazon, and GOG libraries by picking them from a handy, scrollable list.
Installing Heroic Game Launcher is easy. First, go to desktop mode, then click on the Discover store, which is the little shopping bag icon to the left of the folder icon. Search for Heroic, and install the app called Heroic (it’ll likely be the first entry, and will have an icon that looks like a shield with a sword in it).
Once it’s installed, open it, either by clicking the shortcut on your desktop or by searching for it using SteamOS’ version of the classic Windows Start menu (it’ll be to the far left of your taskbar, and will look like the Steam Deck logo).
From here, log into your various alternative game launcher accounts using the Log in button in the top left corner. After that, you could simply install your games and stop here, navigating to desktop mode and opening Heroic Launcher every time you want to play them. But let’s go one step further, so you can access them right from gaming mode (the Steam Deck’s default interface).
First, let’s try installing a game of your choice from the Library tab, to get used to the process. Select the game you want to install, then click Install. You may see the option to change the Install Path or change the “Wine” settings. The latter can help with compatibility, but you likely won’t need to mess with these. You may need to allow a C++ install to actually run certain games, but you can simply click “Install” on the pop-up that shows up when you try running these games to do this.
Once your game is installed, click the three-dot menu in the top right corner and select Add to Steam. This will add the game to your Steam library, so you can open it right from the handheld’s gaming mode.
You could also stop here, just adding games to Steam on a case-by-case basis. But for ultimate convenience, you can add Heroic Launcher itself to the Steam Deck’s gaming mode, to make accessing games in it easier. To do this, click the Steam shortcut on your desktop (or open it from the “Start” menu). From here, click the Add a game button in the bottom left corner, next to the plus sign. Click Add a Non-Steam Game, and in the list that pops up, find and click on Heroic Game Launcher. Click Add Selected Programs.
With this, you’ll be able to access Heroic Game Launcher from within gaming mode by navigating to Library > Non-Steam. This is also where any games you’ve added to Steam from Heroic Game Launcher will show up, and you can use these same steps to add and view other third-party apps within Steam too, even mainstays like Google Chrome. You’ll notice that the art for these might be a little barren. There are a few ways to fix this, but I’ll touch on my favorite below.
Install plugins to customize your experience
By default, SteamOS is pretty snappy and easy to navigate, but fans have taken it upon themselves to make various plugins to help you customize it further. You’ll find these in a program called Decky Loader.
Unlike Heroic Launcher, Decky Loader needs to be installed from a browser. Enter desktop mode, open your browser of choice (Edge is the default), then navigate to decky.xyz. From here, click Download in the top-right corner. Find the install file, either from your browser or the Steam Deck’s File Manager (the folder icon in the taskbar) under Downloads. Double click on it, and then proceed with the installation. For the most stable experience, choose the recommended install option.
Now, to actually use Decky Loader, go back to gaming mode and press the physical three-dot button on your Steam Deck (I’ll refer to that as the “quick settings button” for the rest of this article). Scroll down to the Decky Loader menu, which looks like a plug. Here’s where you can start toying with your plugins.
You’ve got a number of options here, so let’s navigate through where to find plugins and what some of my favorites are. First, select the icon that looks like a market stall (in the top-right corner), and from here, you’ll see all available plugins.
By default, these will be arranged alphabetically, but I have the best luck by navigating to “Sort” and selecting “Most Downloaded First.” This will put the most popular plugins up top. Some of my favorites include CSS Loader, which allows you to change your Steam Deck’s look and theme, and Animation Changer, which allows you to change what animations your Steam Deck plays when it boots or suspends. Download whatever strikes your fancy, and access them through the plug menu when pressing the quick settings button.
Note that, sometimes, installing a new Steam Deck system update might break your plugins. To fix them, navigate to the plug menu and click the cog in the top-right corner, then select “Plugins” and reinstall the ones that have updates. You might also need to update Decky Loader itself, in the General menu on the same page. And if you’re not seeing the plug menu, you’ll need to exit back out to desktop, reinstall Decky Loader using the install file you grabbed earlier, and restart.
Let’s close with an example, and an answer for how to get artwork for your Non-Steam games. In the Decky store, grab the SteamGridDB plugin. Now, with it installed, go to any of your installed Steam games and click the Start button (the three horizontal lines above the right thumbstick). From the menu that pops up, select Change Artwork. You’ll see a number of community-made options that will change how the game’s various icons and posters will show up across your Steam Deck. This will work with almost any game in your library—most have art uploaded to the database this plug-in pulls from—and some non-game programs, too. Most importantly, it will allow you to easily add art to games that don’t have it by default, like Non-Steam games.
Get yourself a dock
The Steam Deck might be a handheld, but that doesn’t mean you can’t use it like a regular desktop pc, too. I’ve already covered how to access desktop mode on the Steam Deck, but if you want to go the extra mile and use it on the big screen, you’ll probably want a dock.
You’ve got a few options for this. I use the unofficial JSAUX dock, mostly because I bought mine before the official Steam Deck dock came out. For firmware support from Valve, you’re going to want the more expensive official Steam Deck dock, but this will merely increase stability—it’s not required.
Whatever you pick, you’ll just want to ensure it has either a DisplayPort or HDMI 2.1 connection (ensure your TV or monitor supports these, too), since those will support high resolutions and fast refresh rates. A built-in ethernet port is also nice, so you can have a wired internet connection, as are extra USB ports.
With a dock, you’ll be able to connect your Steam Deck to a big screen using the USB-C port at the top and the appropriate HDMI or DisplayPort cables for your dock. You’ll also be able to connect as many accessories as your dock will allow. And some docks come with handy bonuses. For instance, storage company Sabrent sells a Steam Deck dock with room for an M.2 SSD, for expanded external storage. JSAUX sells one too, although I can’t speak to it, since it’s not the model I have.
Once you have your dock and it’s all set up, just turn on your Steam Deck and set your TV or monitor to the right input, and you should able to play on the big screen, just like with a standard PC. Note that, depending on your screen’s resolution, you might want to take advantage of manually setting per-game screen resolutions (available in the cog menu after selecting any game, under General > Game Resolution), as some games might need to be set to a lower resolution to run at full speed if connected to a 4K TV. Or, you could set a global max resolution for games by pressing the Steam button and navigating to Settings > Display > Advanced > Maximum Game Resolution.
You can also take advantage of the Steam Deck’s built-in FSR upscaling to help make games look better when running at lower resolutions, by pressing the quick settings button, selecting the lightning bolt icon (this will take you to the Steam Deck’s performance settings), and scrolling down to Scaling Filter. Select Sharp to start upscaling the way I usually do, but there are other filters and modes for you to play with to find the right settings for you, too.
Make emulating games from older systems easy
Aside from playing PC games, you can also use the Steam Deck to emulate games from older systems, too. While you could install emulators yourself (programs that are legal, as long as they don’t come with copyrighted software), industrious fans have created a tool to make installing all the emulators you could possibly need on your Steam Deck way simpler.
It’s called Emudeck, and installing it as as simple as going to desktop mode, opening a browser to emudeck.com, clicking the Download button in the top-right corner, selecting steamOS, and running the install file from either your browser or the Downloads tab in the File Manager.
Honestly, there are a lot of install options you can select here—too many to list. If you’re new to emulation, I suggest selecting Easy Mode, which will get you set up with EmuDeck’s recommended settings. These should work for most people, but if you want to customize things like aspect ratios, filters, and which emulators you install, choose Custom Mode.
Go through the install process, and then to find your emulators, either open Emulation Station (or the alternative frontend you installed using Custom Mode) in gaming mode under Library > Non-Steam Games, or Steam ROM Manager by opening it in the “Start” menu.
As for actually getting games onto your device, you’re generally on your own there: It relies on your collection of retro games and methods for getting files from it. However, many of the same steps outlined in this article will apply.
Make the Steam Deck’s fan quieter
If your Steam Deck’s fan is too loud, you don’t have to just accept it. You’ve actually got multiple steps to control it, including one easy official toggle and one more advanced fan-made option.
Let’s start with the official toggle. If your fan is too loud, press the Steam button on your device, then select System and scroll all the way down until you see Enable updated fan control. Toggle that on to make your fan quieter, but note that doing so could reduce performance, as your system won’t handle heat as well (if this is already toggled, you can actually toggle it off to gain a potential performance boost).
For more detailed control, install Decky Loader using the “Install plugins” hack on this list. Then, install the Fantastic plugin. This will allow you to set a custom fan curve for your Steam Deck, which will change the fan speed based on your Steam Deck’s current temperature. Simply open the plug-in and tap on the curve under the FAN menu to adjust it to your liking.
Adjust the power draw for better battery life
Not every game needs your Steam Deck’s full power. If you’re playing a more lightweight title, considering lowering your Steam Deck’s performance to save some battery life.
To do this, press the quick settings button and select the lighting bolt icon to access the performance menu. From here, you can adjust the TDP Limit to lower how much power your Steam Deck is allowed to use. By default, it’s set to 15 Watts, but on some lightweight games, I’ve been able to get away with 8 watts or less. Play around to find the right power-to-performance balance for you, depending on your game.
While you’re here, you can also set a Manual GPU Clock, which will lower your GPU’s performance, and could also help you gain more battery life. Similarly, you can set your screen’s refresh rate, which will reduce how many frame your system will be able to display per second, but could similarly extend your playtime.
Get a Steam Deck for cheap
Ever since Valve discontinued the Steam Deck LCD, the base price for the Steam Deck has been $550. Not bad for an OLED screen and all this device can do, but much more expensive than the former $400 starting price.
However, Valve will sometimes drop new batches of “certified refurbished” Steam Decks on its store page. These can go for as low as $279, and while these drops are rare, it’s a hefty discount if you can find it.
Valve is your best bet to get a refurbished Steam Deck without any issues, but if you absolutely need one and can’t wait for the next drop, you can try a third-party program. GameStop also sells its own refurbished Steam Decks, although at time of writing, stock is also low there.
Refurbished Steam Decks are probably worth keeping an eye out for, but don’t plan on getting one if you really want a Steam Deck now.
Get Steam beta updates
Valve is constantly iterating SteamOS, but it can take a while for new features to reach the general public. If you can’t wait to get the next big SteamOS update, though, you can easily sign up for beta features. To do so, press the Steam button, then navigate to Settings > System > Beta Participation. From here, join either the Beta or Preview update channels.
These will let you get new SteamOS features more quickly, although they can introduce instability. Still, if you’re fine with tinkering, this will let you get your hands on features like display-off downloads more quickly.
Make your Steam Deck more colorful

Finally, let’s make that screen look a little more vibrant. This can be especially helpful if you’re like me, and you have one of those discontinued LCD Steam Decks.
This used to be limited to a fan-made plugin, but Valve has now added official support for adjusting your Steam Deck’s color settings. To access this, press the Steam button, and navigate to Settings > Display. From here, click Adjust Display Colors. You’ll be taken to a menu where you can adjust the device’s color temperature and vibrance, and see the results on a demo image right up top.
