Key Features
- 【Dual Screen Multiplayer Gaming with AR Glasses】Supports dual-screen output for Switch 2 at up to 4K@60Hz, allowing two players to play simultaneously on separate AR glasses while keeping the main screen for other tasks. Ideal for immersive multiplayer gaming and shared entertainment on portable monitors or AR device, making this USB-C Hub good for gaming setups
- 【Full-Function Type-C Ports】Supports up to two displays via dual Type-C ports, with both ports also supporting data transfer and PD charging. This USBC display adapter allows full-function usage for device expansion or screen mirroring. When two screens are used simultaneously (4K + 1080p), the system will display at the lower resolution (1080p). If one display supports HDR and the other does not, HDR will be disabled for both. Note: This product does not support 5.1 surround sound input or output. Enabling 5.1 channels may cause noise or distortion
- 【High-Power Charging & Data Transfer】This USB-C video output hub supports PD 100W charging for upstream host devices such as Switch 2, Steam Deck, laptops, tablets, and phones, while also providing USB 3.0 data transfer up to 5Gbps. For Switch 2 TV mode or other high-power devices, use a PD 65W or higher charger for stable performance. The two USB-C display output ports are mainly designed for video transmission to AR glasses, portable monitors, and USB-C displays, with a maximum power output of 5V⎓2A, whether using one port or both simultaneously
- 【Expanded Workspace & Entertainment】Connect via dual Type-C ports or C-to-HDMI cables to monitors, TVs, or projectors. Supports shared viewing and immersive dual-screen setups, ideal for multiplayer gaming, virtual workspaces, remote meetings, creative design, or study/training. Built with an aluminum alloy shell for durability and excellent heat dissipation. Plug and play, no drivers required
- 【Wide Compatibility & Notes】 Supports input devices: Switch 2, laptops, tablets, phones; and output devices: AR glasses, portable monitors, Studio Display (video only), and other Type-C displays. Connect two AR glasses, two portable monitors, or mix monitors and projectors for dual-screen or mirrored display. Plug and play with an aluminum alloy shell for durability. Note: Does not support video capture; some Android/HarmonyOS tablets may only display one screen. For AR glasses, select DP audio output if no sound
- 【Compatibility & Heat Notice】This product uses a chip optimized for Switch 2 compatibility, offering broader compatibility than standard hubs. The PD input mainly powers the upstream video output device rather than external displays. If connected displays require more power than the output ports can provide, black screens, flickering, or disconnects may occur. Portable monitors and displays should use separate external power during use. Due to the high-performance chipset, the device may become warm during operation. Please ensure proper ventilation and avoid enclosed spaces
