The ROG Ally was designed to be an ultra-portable, handheld gaming machine that can transform into whatever you need at any given moment. Want to throw your games up on the big screen and play with friends? All you need is a USB-C to HDMI dock that can charge the Ally at the same time, like the ROG 65W Gaming Charger Dock or one of our XG Mobile external GPUs.
This is part of our ultimate guide to the ROG Ally series of articles.
We’ll be using the 65W Gaming Charger Dock for the purposes of this guide, but if you’re using an XG Mobile, the steps will be similar — you’ll just want to check out our XG Mobile guide to get it up and running, then come back here for the display and controller configuration.
Step one: Connect your Ally to the dock
Our 65W Gaming Charger Dock includes three ports, so connecting the Ally is fairly simple. Plug a USB Type-C cable into the port on the top your Ally, then plug the other end into the Type-C port on the Gaming Charger Dock. Then connect an HDMI cable — ideally an Ultra High Speed HDMI Cable if you have a 4K TV — to the Gaming Charger Dock, and the other end into an HDMI port on your TV or monitor. The Gaming Charger Dock also has a USB Type-A port for any peripherals you may want to use.
Step two: Adjust your display
When you plug the Ally into the TV, the screen will go black for a moment as it detects the new display, after which you should see the Ally’s display appear on your TV or monitor. By default, it’ll be set to show only on the TV, but you can customize this depending on your preferences. Hold the M1 or M2 button on the back of the Ally and press X to bring up Windows Projection Mode. From there, you can choose to duplicate the Ally’s screen on the TV or extend the display to the TV. I generally prefer the default setting, but you can tweak this how you like.
Next, make sure your TV’s display settings are adjusted properly. Open the Windows Start menu and head to Settings > System > Display. Under Display Resolution, set your preferred resolution for the TV. The Ally was designed to play at 1080p, so setting your TV resolution to 1920x1080 will give you the simplest plug-and-play experience. Depending on the game you’re going to play, though, you may be able to render it at 4K, or 3840x2160, which will produce sharper graphics. You can also use FSR or RSR to upscale the game from 1080p to 4K if need be, as described in this guide.
Finally, scroll down to Advanced Display, choose your TV from the “Select a display” dropdown at the top, and make sure the refresh rate is set to at least 60Hz. This will allow your TV to display smooth gameplay at 60 frames per second.
Step three: Connect your controller(s) and disable the built-in gamepad
Now that your display is set up, you’ll need to connect your controllers. Grab your favorite wired or wireless gamepad — might we suggest the ROG Raikiri or ROG Raikiri Pro? — and connect it to your Ally. For wired and 2.4GHz wireless controllers, you can plug it into the remaining USB port on the Gaming Charger Dock, and for Bluetooth controllers, you can connect them from Windows’ Settings > Bluetooth & Devices. The Ally can support up to four controllers.
To play with an external controller, you’ll also need to disable the Ally’s built-in gamepad, so games don’t detect it instead. Open the Command Center and turn the Embedded Controller option off.
Step four: Game on
From there, you’re all set! You should be able to navigate Armoury Crate with your controller from the couch, allowing you to launch your games and get playing.
