The ROG Ally stormed onto the gaming scene in 2023, offering a compelling alternative to the Steam Deck. Its Windows operating system grants access to an even wider library of games. The 2023 ROG Ally X iteration not only boosted internal specs but also significantly improved ergonomics and cooling.
While the Ally excels in portability, connecting it to a larger screen for a more immersive couch gaming experience is a definite plus. Both ROG Ally models offer external display connectivity for big-screen gaming enjoyment.
Connecting Your ROG Ally to a TV or Monitor with an Adapter
Connecting your ROG Ally to a TV or monitor is straightforward using an adapter. Several options exist, from compact dongles to dedicated cables and the official ROG dock, offering flexibility to suit your preferences.
What You'll Need

ASUS ROG 65W Charger Dock
Asus simplifies the process with the official ROG Gaming Charger Dock. This compact solution also charges your device. Simply connect via a USB-C and HDMI cable. The dock also includes a USB-A port for keyboard/mouse connectivity.
Alternatively, a third-party USB-C to HDMI adapter connects directly to the Ally's USB-C port. An HDMI cable links the adapter to your TV or monitor. A USB-C to HDMI cable offers a single-cable solution. Some adapters include a passthrough USB-C port for charging; if so, you'll need an extra USB-C cable and power adapter.
Step-by-Step Instructions
- Plug a USB-C to HDMI adapter (or cable) into the Ally's top USB-C port. If using the ROG Gaming Charger Dock, connect a USB-C cable from the Ally to the dock's USB-C port.
- Connect an HDMI cable from the adapter (or dock) to your TV or monitor's HDMI port. For a direct USB-C to HDMI cable, connect directly to your TV/monitor.
- (Optional) If your adapter has a passthrough USB-C port, connect your power adapter for charging.
- Power on the Ally; it should automatically detect and output the video signal.
- Switch your TV or monitor's input to the correct HDMI source.
Connecting Your ROG Ally to a TV or Monitor with a Docking Station
For a more console-like setup, consider a docking station. While there's no official ROG Ally dock (beyond the charging dock), many third-party options are available. These offer a stand for your Ally and often include charging capabilities.
What You'll Need

JSAUX Docking Station HB0603
Basic docks usually include HDMI and USB-C passthrough charging. More advanced docks offer extra USB ports, Ethernet, SD card slots, and even DisplayPort for multiple displays. Smaller, portable docks are ideal for travel.
Step-by-Step Instructions
- Place your ROG Ally in the dock.
- Connect the USB-C power cord to the Ally's USB-C port.
- Connect your power adapter to the dock's USB-C charging port.
- Connect an HDMI cable from the dock to your TV or monitor.
- Power on the Ally; it should automatically detect and output the video signal.
- Switch your TV or monitor's input to the correct HDMI source.
You'll Also Need a Controller
While keyboard/mouse support exists, a wireless controller provides a more comfortable big-screen gaming experience. The ROG Ally supports Bluetooth controllers.

Sony DualSense

Xbox Elite Series 2 Controller

8BitDo Ultimate Controller

GuliKit KingKong 3 Max Controller

PowerA Wireless GameCube Style Controller
Consider options like the DualSense, Xbox Wireless Controller, or Switch Pro Controller, along with various third-party choices. 2.4GHz wireless controllers often offer lower latency and better range than Bluetooth. Wired USB controllers are also an option for close proximity.
