Follow these steps to set up your JTECH-4KSP4 HDMI Splitter:

1. Өчүрүү түзмөктөрү: Туташтыруудан мурун, бардык HDMI булак түзмөктөрү жана дисплейлери өчүрүлгөнүн текшериңиз.
2. HDMI булагын туташтырыңыз: Баштапкы түзмөгүңүздөн (мисалы, Blu-ray ойноткуч, оюн консолу, компьютер) HDMI кабелин туташтырыңыз HDMI киргизүү бөлгүчтөгү порт.
3. HDMI дисплейлерин туташтыруу: HDMI кабелдерин туташтырыңыз HDMI чыгышы 1-4 ports on the splitter to your respective display devices (e.g., TVs, monitors, projectors).
4. Туташуу кубаты: Камтылган кубат адаптерин розеткага сайыңыз DC 5V port on the splitter, then plug the adapter into a power outlet. The Power LED will illuminate.

6. Иштөө нускамалары

Once connected, the splitter operates largely automatically. Consider the following for optimal performance:

• Күйгүзүү/өчүрүү: The splitter powers on automatically when connected to power. Disconnect the power adapter to power off.
• Downscaling Function: колдонуу Кичирейтүү которгучу to enable or disable 1080p downscaling. Set to 'On' if you have a mix of 4K and 1080p displays and want all displays to receive a signal. Set to 'Off' if all your displays support 4K resolution or if you prefer the original resolution without downscaling.
• EDID башкаруу: The splitter automatically copies EDID (Extended Display Identification Data) from the connected displays. It prioritizes Output 1, then Output 2, and so on. Ensure your primary display is connected to Output 1 for the best EDID negotiation.

Image 6.1: Multi-Resolution Output (MRO) function of the JTECH-4KSP4. This image demonstrates how the splitter can send a 4K signal to a 4K UHD display and a downscaled 1080p signal to a Full HD display simultaneously, managed by the 'On/Off Downscale' switch.

7. Multi-Resolution Output (MRO) Function

The MRO feature is crucial for environments with mixed display resolutions. When enabled, the splitter intelligently manages output signals:

• If a 4K source is connected and the Кичирейтүү которгучу is 'On':
• 4K displays will receive the original 4K signal.
• 1080p displays will receive a downscaled 1080p signal.
• Эгерде Кичирейтүү которгучу is 'Off':
• All displays will attempt to receive the highest common resolution supported by the EDID of the primary display. If a 1080p display is connected and the source is 4K, the 1080p display may not show an image unless downscaling is enabled.

Эскертүү: The splitter does not downscale to 720p or lower, nor does it downscale HDR metadata.
