JUCONU Wireless HDMI Adapter 4K/1080p Screen Mirroring

JUCONU Wireless HDMI Adapter wirelessly mirrors or extends your iPhone, iPad, Android, Windows laptop, or tablet to an HDTV, monitor, or projector in up to 4K resolution.

Turn any HDMI-equipped display into a bigger, cable-free screen for movies, presentations, games, and video calls. The JUCONU dongle supports Miracast, AirPlay, and DLNA protocols so most modern devices can cast or mirror with minimal setup. It handles 4Kx2K@30Hz and 1080p@60Hz output, offers an extend mode to use your device separately while streaming, and requires only a powered HDMI port or USB power source.

How do I set up the JUCONU adapter quickly?

Setup is designed to be simple: plug the adapter into your TV or projector HDMI port, connect its USB power, then select the wireless display option on your source device. No additional Bluetooth pairing or special apps are required for basic mirroring.

• Plug the dongle into HDMI and a USB power outlet
• Choose the display input on your TV or projector
• Open mirroring or cast settings on your phone, tablet, or laptop
• Select the JUCONU device from the list and begin streaming

Which devices and apps are compatible with the dongle?

JUCONU works broadly with iOS, macOS, Android, and Windows devices using AirPlay, Miracast, or DLNA. Most web browsers and common apps cast media successfully; however, some DRM-protected services on Apple devices may not stream due to HDCP restrictions.

• iPhone, iPad, iPod touch, and many iPad Pro/Air/Mini models (iOS 9.0+)
• Android phones and tablets with casting/mirroring support
• Windows laptops and PCs using Miracast or display projection
• Note: HDCP-protected apps (e.g., certain streaming apps on iOS) may be restricted

What video quality and modes can I expect?

The adapter supports up to 4Kx2K at 30Hz and multiple 1080p modes, so you can stream high-definition video or run presentations with clear text. It also includes an extend mode to use your device independently while sending content to the big screen.

• 4K x 2K at 30Hz for high-resolution displays
• 1080p at 60Hz for smooth video playback
• 3D and 720p compatibility for older displays and media
• Mirror and extend modes for flexible workflows

What should I troubleshoot if the connection fails?

First verify the dongle has stable USB power and the TV input is set correctly. Restart the source device, check Wi-Fi network settings, and ensure the casting feature is enabled. For iOS users, remember some DRM-protected apps will refuse casting.

• Confirm USB power supply and HDMI input selection
• Restart adapter and source device if needed
• Use the device's native cast/mirror menu to locate JUCONU
• Try a different HDMI port or a powered USB adapter for stable power

Who is this for: JUCONU's wireless HDMI adapter is ideal for anyone who wants a clutter-free way to enjoy photos, videos, streaming, presentations, and casual gaming on a larger screen. It’s especially useful for small-home theaters, classrooms, business meetings, and travellers who need a compact transmitter for displays. If you rely on HDCP-protected streaming apps on Apple devices for the majority of your viewing, double-check compatibility before purchase; otherwise this adapter offers broad device support and high-definition output for everyday casting needs.
