Restart the projection function on the computer (switch modes with Win+P for Windows, turn Screen Mirroring off and on for Mac).
• Choppy wireless projection:
1. Ensure stable WiFi signal (2.4G for long distances, 5G for short-distance high speed);
2. Close other bandwidth-intensive applications (e.g., download software, video players).
When a podium is placed next to the LED screen in a meeting room, the laptop interface can be selected according to the on-site environment, and the projection button can be placed on the podium for the speaker to project immediately upon taking the stage. The DEKO wireless projection solution takes into account the diversity of laptop interfaces and is suitable for all types.
We support the PPT Presenter Mode, where the speaker can view manuscripts or notes while participants only see the PPT content. The tablet projection function is also available – the screen of iPads or Android tablets can be wirelessly projected to the large screen while maintaining network connection. The DEKO wireless projection box is compatible with laptops, tablets and mobile phones, realizing wireless signal transmission with one transmitter and one receiver.
The DEKO wireless projection solution is suitable for multimedia classrooms in enterprises, government agencies and universities, providing users with an intelligent, convenient and efficient projection experience. It has been widely applied with customers across the country. For more information, welcome to visit the DEKO Commercial official website or contact us for consultation.
3. Operational Benefits: Triple Gains in Safety, Economy and Environmental Protection
The promotion and application of this system have brought significant improvements to the operation of plateau tunnels, specifically manifested in:
3.1 Safety Dimension: Reducing Accident Risks
• A stable lighting environment shortens drivers' visual adaptation time and avoids operational errors caused by sudden light and dark changes.
• Uniform illumination distribution eliminates road surface shadows and improves the recognition of pedestrians and vehicles, especially effective in curves or ramps.
• Feedback from traffic management departments shows that the accident rate in tunnels has decreased by about 30% after the adoption of low-temperature resistant LED lighting.
3.2 Economic Dimension: Life-Cycle Cost Optimization
• High energy efficiency: The light efficiency of LED light sources can reach more than 120lm/W, saving more than 40% energy compared with traditional high-pressure sodium lamps (about 80lm/W).
• Long service life: The designed service life is ≥50,000 hours, 2-3 times that of high-pressure sodium lamps, reducing replacement frequency and maintenance costs.
• Modular design: Local replacement of faulty modules shortens the single maintenance time from 4-6 hours for traditional equipment to less than 1 hour.
