What Is the UHDS-102C?
The OREI UHDS-102C is a compact 1x2 HDMI 2.0 splitter with a fixed 0.6-meter HDMI input cable. It distributes one HDMI source to two HDMI displays simultaneously.
The splitter supports resolutions up to 4K@60Hz YUV 4:4:4, 18Gbps bandwidth, HDR, HDCP 2.2, 3D video, and automatic 4K-to-1080p downscaling for mixed-resolution displays.
The UHDS-102C is useful for home entertainment systems, gaming setups, classrooms, conference rooms, retail displays, trade shows, and other installations where the same source must appear on two displays.
IMPORTANT — UHDS-102C Is a 1x2 HDMI Splitter
The UHDS-102C duplicates one HDMI source to two HDMI displays.
| Function | Support |
| 1 HDMI input | Supported |
| 2 HDMI outputs | Supported |
| Same source on both displays | Supported |
| Simultaneous output | Supported |
| Different content on each display | Not supported |
| Matrix switching | Not supported |
| Extended desktop creation | Not supported |
This product mirrors the same HDMI source on both displays. It does not create two independent screens.
IMPORTANT — Supports 4K@60Hz 4:4:4
The UHDS-102C supports high-resolution HDMI video up to 4K@60Hz YUV 4:4:4.
| Feature | Support |
| 4K@60Hz | Supported |
| YUV 4:4:4 | Supported |
| 4K@30Hz | Supported |
| 1080p | Supported |
| HDR | Supported |
| Full 3D | Supported |
| 18Gbps bandwidth | Supported |
| 12-bit color per channel | Supported |
The HDMI source, cables, and displays must all support the selected resolution and video format.
IMPORTANT — Automatic 4K-to-1080p Downscaling
The UHDS-102C can send 4K video to a compatible 4K display while simultaneously downscaling the signal to 1080p for a Full HD display.
| Display Setup | Output Behavior |
| Two 4K displays | Both can receive 4K |
| Two 1080p displays | Both receive 1080p |
| One 4K and one 1080p display | 4K display receives 4K; Full HD display receives 1080p |
| 1080p input signal | Remains 1080p |
Downscaling reduces a supported 4K signal to 1080p. It does not upscale 1080p content to 4K.
IMPORTANT — Downscaling Has Format Limitations
The manual states that downscaling supports these 4K@60Hz input formats:
| Downscaling Input Format | Support |
| 4K@60Hz 4:4:4 | Supported |
| 4K@60Hz 4:2:0 | Supported |
| HDR10 | Supported |
If a Full HD display has sound but no picture, or shows a pink screen, change the HDMI source to a supported downscaling format or reduce the source resolution.
IMPORTANT — HDCP 2.2 and HDCP 1.4 Support
The UHDS-102C supports both HDCP 2.2 and HDCP 1.4.
| Specification | Support |
| HDCP 2.2 | Supported |
| HDCP 1.4 | Supported |
| Protected 4K content | Supported with compatible equipment |
| Non-HDCP-compliant display | May not show protected content |
All connected devices must support the required HDCP version. An incompatible display or intermediary device may produce no picture, sound without video, or a pink screen.
IMPORTANT — Fixed HDMI Input Cable
The UHDS-102C includes a fixed 0.6-meter HDMI input cable.
| Connection | Description |
| Fixed male HDMI cable | Connects to the HDMI source |
| HDMI OUTPUT 1 | Connects to the first display |
| HDMI OUTPUT 2 | Connects to the second display |
| Micro-USB | Supplies DC 5V power |
The fixed input cable cannot be removed or replaced.
IMPORTANT — This Is Not an Audio Extractor
The UHDS-102C passes HDMI audio to both connected displays but does not provide separate audio extraction ports.
| Audio Feature | Support |
| HDMI audio pass-through | Supported |
| LPCM | Supported |
| Dolby Digital | Supported |
| Dolby TrueHD | Supported |
| DTS | Supported |
| DTS-HD Master Audio | Supported |
| Optical audio output | Not included |
| Analog audio output | Not included |
| ARC/eARC extraction | Not listed |
Use a dedicated HDMI audio extractor if separate optical or analog audio output is required.
Ports, Controls, and Indicators
| Port, Control, or Indicator | Function |
| Fixed HDMI IN cable | Connects to the HDMI source |
| OUTPUT 1 | Connects to HDMI Display 1 |
| OUTPUT 2 | Connects to HDMI Display 2 |
| OUTPUT 1-2 LEDs | Indicate HDMI output connection status |
| Micro-USB port | Connects the DC 5V USB power cable |
| Power LED | Indicates that the splitter is powered |
| RESET button | Resets the splitter if operation becomes unstable |
The manual’s panel description contains a labeling error for RESET, but the diagram identifies the top control as the RESET button.
Step-by-Step Setup
- Connect the fixed HDMI input cable to the HDMI source device.
- Connect HDMI OUTPUT 1 to the first TV, monitor, or projector.
- Connect HDMI OUTPUT 2 to the second display.
- Connect the included Micro-USB power cable to the splitter.
- Connect the other end of the USB cable to a suitable 5V USB power source.
- Power on the HDMI source and both displays.
- Check that the Power LED is illuminated.
- Check the OUTPUT 1 and OUTPUT 2 indicators.
- Test video and audio on both displays.
Micro-USB Power Requirement — Critical
The UHDS-102C requires USB power for reliable operation.
| Power Detail | Value |
| Power connection | Micro-USB |
| Required input | DC 5V |
| Maximum power consumption | 5W |
| Included power accessory | Micro-USB power cable |
| Power adapter | Not listed in package contents |
If the Power LED is off, check the Micro-USB cable and USB power source.
HDMI Cable Requirement — Critical
Use standard HDMI 2.0 cables for 4K@60Hz.
| Signal Type | Maximum Output Cable Length Listed |
| 4K@60Hz 4:4:4 | 5 m / approximately 16 ft |
| 4K@30Hz | 10 m / approximately 33 ft |
| 1080p | 10 m / approximately 33 ft |
Poor-quality or overly long cables may cause:
- No video
- Screen flashing
- Flickering
- Intermittent signal
- Pink screen
- 4K@60Hz failure
- HDR failure
- Audio dropouts
For troubleshooting, test each HDMI cable directly between the source and display.
Understanding the Connection Diagram
