3. คู่มือการใช้งาน

3.1 การทำงานพื้นฐาน

Once all connections are made and the splitter is powered on, the HDMI source signal will be duplicated and sent to both HDMI OUT 1 and HDMI OUT 2. The splitter automatically detects the optimal resolution for each connected display.

3.2 Down-scaling Function (OUT 2)

The HDMI OUT 2 port supports down-scaling from 4K (60Hz/50Hz/30Hz) to 1080p 60Hz. This feature is crucial when connecting a 4K source to a 4K display (OUT 1) and a 1080p display (OUT 2) simultaneously. To enable down-scaling, ensure the เครื่องขูด switch for OUT 2 is set to ON.

หมายเหตุสำคัญ:

• The splitter OUT 2 down-scales 4K to 1080p ONLY; no other resolutions are supported for down-scaling.
• It does NOT down-scale HDR Dolby Vision (4K60 4:2:2) and Frequency. Attempting to do so may result in washed-out colors or an unusable signal.

3.3 การตั้งค่า EDID

The EDID (Extended Display Identification Data) settings allow you to configure the splitter's behavior regarding video and audio formats. This is particularly useful for ensuring compatibility with various displays and audio devices.

To set EDID No.31 via micro-USB by PC, follow the instructions in the user manual or consult the provided video for detailed steps. This setting is recommended for achieving 4K 60Hz HDR Dolby Vision TV and 7.1ch Dolby Atmos soundbar synchronization.

3.4 CEC Control

CEC (Consumer Electronics Control) functionality is supported on HDMI OUT 1 only. This allows for unified control of connected devices through a single remote.

3.5 HDCP Bypass

The splitter supports HDCP 2.2. For specific scenarios, you may need to set HDCP bypass via PC. Refer to the user manual for advanced configurations.

• The threaded power adapter is designed to prevent power loss; ensure it is tightened properly.

5 การแก้ไขปัญหา

1. No Display on 4K TV: Connect the 4K TV to HDMI Splitter OUT 1 first. After the 4K TV displays correctly, then connect the second TV to Splitter OUT 2.
2. 1080p TV Not Displaying: If using a 4K and 1080p TV together, ensure the 1080p TV is connected to Splitter OUT 2 and the SCALER switch for OUT 2 is ON.
3. Power Cycling Order: When turning off and on your TV and splitter, always turn on Splitter OUT 1 4K TV first, especially when 4K and 1080p TVs work together.
4. HDR/Dolby Atmos Issues: If your HDMI source and TV support HDR Dolby Vision/Dolby Atmos, the splitter should support them accordingly. First, connect the HDMI source directly to the TV (without the splitter) to confirm the TV supports the HDMI source's HDR. If the TV does not display HDR correctly, it indicates a TV issue, not a splitter issue. After this test, set the HDMI source HDR feature to match the splitter's HDR settings.
5. เอาต์พุตเสียง SPDIF: SPDIF Optical 5.1CH audio output follows the audio format of Splitter OUT 2.
6. Dolby Vision Down-scaling: Splitter OUT 2 down-scales 4K to 1080p only. It does NOT down-scale Dolby Vision; attempting to do so will result in washed-out colors.
7. คุณภาพสายเคเบิล: Use good quality HDMI 2.0 standard cables less than 10 meters (33 feet) for optimal performance.
