You can now use the Meta Quest as a screen for HDMI devices
Briefly

Meta's new app transforms Quest 3, 2, and Pro headsets into versatile second screens for consoles and computers, though it requires affordable additional hardware.
The Meta Quest HDMI Link app isn't as straightforward as Air Link; it requires an extra UVC capture card for connecting external video devices.
Users need to connect their devices to a UVC-compatible capture card, allowing the Quest to display video from consoles with minimal latency.
While offering a 1080p display at 60FPS, the app enables a unique solution for those wanting to utilize their VR headset for multimedia without traditional projectors.
