Just Monitor: HDMI Display
UVC capture. No PC software.
Free · In‑App Purchases
iPad
Turn your device into a work monitor — no PC-side software needed. Add a low-cost UVC HDMI capture dongle (~$10) and a USB-C connection. All display features free.
View your PC screen on a device you already have. Just Monitor displays HDMI video through a compatible UVC capture device, turning a supported USB-C device into a work monitor. No PC app, background service, or virtual display driver is required.
What you need:
- A supported USB-C device that can run this app
- A compatible UVC capture device (required separately)
- A PC with video output and the appropriate cables or adapters
Example: PC HDMI output → UVC capture device → USB-C viewing device. A USB cable directly between the PC and viewing device is not sufficient. USB-C video sources also require compatible capture hardware and any necessary adapters.
Useful when you cannot add software to a work PC, or want another screen for documents while working away from your desk. Mirroring or extending your desktop depends on the PC's video output and display settings.
Use Normal mode to see the whole document, or No Margins to fill the screen. Pinch to enlarge small text up to 3×. Panning stops at the edges of the image; double-tap to return to the starting view. Hiding the controls does not resize the video.
Main features:
- Use the full screen as your viewing area
- Normal mode shows the complete source without cropping or distortion
- No Margins mode preserves aspect ratio while filling the screen; pan to inspect cropped edges
- Practical 1–3× pinch zoom with bounded panning
- Double-tap to reset to the current mode's default position
- Show or hide the system status bar and app controls independently
Display features are identical on the free and ad-free plans. Purchases remove advertising only.
Requires a supported USB-C device that can run this app, a compatible UVC capture device, and a computer or device with video output. Just Monitor does not control the computer or add an extended-display driver. Compatibility varies by hardware combination.
