5.3 Connecting Video Sources
Choose the appropriate cable for your device and connect it to the corresponding input port on the monitor.
- HDMI: Connect an HDMI cable from your device (e.g., PC, Raspberry Pi, TV-Box) to the monitor's HDMI input.
- VGA: Connect a VGA cable from your PC or laptop to the monitor's VGA input.
- AV: Connect RCA cables from your DVD player or TV-Box to the monitor's AV input.
- BNC (CVBS): Connect a BNC cable from your CVBS security camera to the monitor's BNC input.
- TVI/CVI/AHD Cameras: For these camera types, an external converter is required. Connect your TVI/CVI/AHD camera to the converter's input, and then connect the converter's HDMI output to the monitor's HDMI input.

6. Operating Instructions
6.1 Power On/Off
Press the power button located on the front or side of the monitor to turn it on or off. The power indicator light will illuminate when the monitor is on.
6.2 Input Source Selection
Use the "Input" or "Source" button on the monitor to cycle through available input sources (HDMI, VGA, AV, BNC, USB). Select the input corresponding to your connected device.
6.3 Menu Navigation and Image Settings
Use the menu buttons (Menu, Up, Down, Enter) to navigate the On-Screen Display (OSD) menu. Adjust settings such as:
- Brightness: Adjust the overall luminance of the screen.
- Contrast: Adjust the difference between light and dark areas.
- Color Temperature: Select preset color temperatures (e.g., Warm, Cool, User) or adjust RGB values manually.
- Aspect Ratio: Choose between 16:9, 4:3, or other available options.
6.4 Mirror Flip Function
The monitor supports horizontal and vertical image flipping, which is useful for various mounting configurations, such as teleprompter use or ceiling mounts.
Figure 5: Demonstration of the mirror flip function. The image shows the display in normal, horizontally flipped, vertically flipped, and both horizontally and vertically flipped orientations.
6.5 CCTV Monitor Usage
When used as a CCTV monitor, connect your CVBS security camera directly to the BNC input. For AHD/TVI/CVI cameras, use an external converter as described in Section 5.3.
Figure 6: The monitor displaying footage from a CCTV camera. Note that the BNC input supports CVBS signals only. For AHD/TVI/CVI cameras, an external converter is necessary.
6.6 Simultaneous BNC + HDMI Output (with Converter)
When using the external 4K HD to HDMI converter (for AHD/TVI/CVI cameras), it is possible to output the video signal simultaneously to two displays: one via BNC and one via HDMI. This requires a converter that supports dual output.
Figure 7: Connection diagram for simultaneous BNC and HDMI output. A single camera input is fed into a converter, which then provides both a BNC output to a tester monitor and an HDMI output to the Eyoyo monitor.
7. Maintenance
7.1 Cleaning the Monitor
- Always unplug the monitor from the power outlet before cleaning.
- Use a soft, lint-free cloth to gently wipe the screen and exterior surfaces.
- For stubborn marks, slightly dampen the cloth with water or a mild, non-abrasive screen cleaner. Do not spray liquid directly onto the screen.
- Avoid using alcohol, ammonia, or abrasive cleaners, as they can damage the screen or casing.
7.2 Storage
When not in use for extended periods, store the monitor in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to keep the original packaging for safe storage and transport.
