Business Meetings
Multiple devices take turns projecting screens to display solutions, and the touch back function enables real-time annotation and modification, improving decision-making efficiency by 40%.
Education and Training
Courseware is projected on the main screen and experimental videos on the secondary screen; HD pictures combined with low-latency transmission make knowledge transfer clearer.
Product Display
Store large screens synchronize product image libraries in mobile phones or demonstration videos on computers in real time to attract customers' attention.
Remote Collaboration
When working from home, project computer content to a large screen and use video conference software to make the communication experience closer to the offline scenario.
FAQ (Frequently Asked Questions)
Which devices work with the Qtboard Wireless Screen Transmitter?
The receiver works with all display devices that have an HDMI port (e.g., TVs, projectors, monitors). The transmitter supports Windows/macOS computers and Android/iOS phones/tablets, regardless of brand or model.
Do I need internet for screen projection?
No. You can connect via two methods: either join the same local network or connect directly to the transmitter’s hotspot—screen projection works even without an internet connection.
Is there picture transmission latency? Does it affect daily use?
Latency is under 120ms (hardly noticeable to the human eye). It won’t affect meetings or teaching, whether you’re playing 1080P videos, sliding through PPTs, or editing documents in real time.
How many devices can connect at once? Can it do split-screen display?
It supports 8 devices connected simultaneously (for standby and quick content switching). Some models offer split-screen mode to display content from 2-3 devices at once (great for comparing solutions).
Does the device need a separate power supply? Is installation hard?
No separate power supply is needed—the receiver gets power via a Type-C port (using a monitor or projector’s USB port). Installation takes just two steps (plug in receiver and transmitter) and takes less than 1 minute.
How to keep files private during transmission?
It uses dual security: WPA2-PSK protocol + AES encryption to protect the transmission link, and an extended screen mode that only projects a specific window (hiding private files on your computer desktop).
What’s the effective projection distance? Is the signal stable?
It works up to 15 meters in unobstructed areas (suitable for large conference rooms). It uses 5GHz WiFi for strong anti-interference, avoiding signal conflicts with 2.4G WiFi or Bluetooth.
