What Is the DP-102?
The OREI DP-102 is an 8K 1x2 DisplayPort splitter. It takes one DisplayPort source signal and sends it to two DisplayPort monitors or displays.
The DisplayPort source connects to DP INPUT on the splitter, and two DisplayPort monitors connect to OUT 1 and OUT 2.
The DP-102 supports DisplayPort 1.4 and MST 1.2, with video bandwidth up to 32.4Gbps. It supports resolutions up to 8K@30Hz, dual 4K@60Hz, and triple / quad 4K@30Hz configurations, along with SST mirror mode, MST extended desktop mode, panoramic video wall support, HDR, HDR10, HDR10+, Dolby Vision, HLG, DSC, 3D video, and DisplayPort audio formats including LPCM, Dolby Digital, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X, and DSD. The manual’s application diagrams show both SST mode for duplicate display output and MST mode for extended desktop output from a PC to two monitors.
The DP-102 is useful for multi-monitor workstations, gaming setups, control rooms, presentations, digital signage, professional AV systems, trading desks, design workstations, and display setups where one DisplayPort source needs to connect to two DisplayPort displays.
IMPORTANT — DP-102 Is a 1x2 DisplayPort Splitter
The DP-102 distributes one DisplayPort source to two DisplayPort outputs.
| Function | Support |
| 1 DisplayPort input | Supported |
| 2 DisplayPort outputs | Supported |
| Mirror mode | Supported through SST |
| Extended desktop | Supported through MST |
| Panoramic / video wall mode | Supported |
| HDMI input | Not supported |
| HDMI output | Not supported |
| USB-C input | Not supported |
This product is for DisplayPort connections only. It is not an HDMI splitter.
IMPORTANT — Supports SST and MST Modes
The DP-102 includes a mode switch for SST and MST.
| Mode | Function |
| SST | Duplicates the DisplayPort source to two monitors |
| MST | Extends the DisplayPort source to two monitors |
Use SST mode when both monitors should show the same image.
Use MST mode when the computer should detect two separate displays for extended desktop use.
IMPORTANT — Extended Desktop Requires MST Support
The DP-102 can extend a desktop to two monitors when MST mode is used.
| Requirement | Needed for Extended Desktop |
| Source device supports DisplayPort MST | Required |
| Graphics card supports multi-display output | Required |
| Operating system supports extended displays | Required |
| Mode switch set to MST | Required |
If the source device or graphics card does not support MST, the splitter may only mirror the same image.
IMPORTANT — Supports up to 8K@30Hz
The DP-102 supports high-resolution DisplayPort video.
| Resolution / Setup | Support |
| 8K@30Hz | Supported |
| Dual 4K@60Hz | Supported |
| Triple / Quad 4K@30Hz | Listed in manual |
| 4K@120Hz | Listed in supported resolution table |
| 5120x2160@60Hz | Supported |
| 1080p@60Hz | Supported |
To get the highest resolutions, the source device, GPU, DisplayPort cables, and monitors must all support the required DisplayPort bandwidth and resolution.
IMPORTANT — DisplayPort 1.4 and MST 1.2
The DP-102 supports DisplayPort 1.4 and MST 1.2.
| Specification | Support |
| DisplayPort version | DP 1.4 |
| MST version | MST 1.2 |
| Video bandwidth | 32.4Gbps |
| DSC | Supported |
| HDR | Supported |
Use a DisplayPort 1.4 source and DisplayPort 1.4 cables for best performance.
IMPORTANT — GPU Compatibility
The manual states that the DP-102 is designed to work with modern GPUs and multi-display platforms.
Compatible multi-display technologies include:
| Platform | Support |
| AMD Eyefinity | Supported |
| NVIDIA Surround | Supported |
| Intel Collage | Supported |
| DP 1.4 graphics cards | Supported |
For best results, keep GPU drivers updated and confirm the graphics card supports the intended number of displays and resolution.
IMPORTANT — This Is Not an HDMI Splitter
The DP-102 only uses DisplayPort ports.
| Port Type | Support |
| DisplayPort input | Supported |
| DisplayPort outputs | Supported |
| HDMI input | Not supported |
| HDMI outputs | Not supported |
If your source device or display only has HDMI, use the correct DisplayPort-to-HDMI adapter or choose an HDMI splitter model instead.
IMPORTANT — Power Adapter Is Required
The DP-102 uses a DC 5V/1A power supply.
| Power Detail | Value |
| Power supply | DC 5V/1A |
| Maximum power consumption | 2.2W |
| Power LED | Red LED turns on when powered |
The package includes one 5V/1A power supply.

- Set the mode switch to SST.
- Connect the included DC 5V/1A power adapter.
- Power on the source device, splitter, and both monitors.
- Confirm the red Power LED is on.
- Both displays should show the same source image.
Step-by-Step Setup — MST Extended Desktop Mode
- Connect the DisplayPort source device to DP INPUT on the DP-102.
- Connect Monitor 1 to OUT 1.
- Connect Monitor 2 to OUT 2.
- Set the mode switch to MST.
- Connect the included DC 5V/1A power adapter.
- Power on the source device, splitter, and monitors.
- Open the computer display settings.
- Select Extend these displays if the system does not automatically extend.

DisplayPort Cable Requirement — Critical
Use high-quality DisplayPort cables rated for the resolution being used.
| Use | Recommendation |
| 8K@30Hz | DisplayPort 1.4 cable |
| Dual 4K@60Hz | DisplayPort 1.4 cable |
| 4K HDR | DisplayPort 1.4 cable |
| MST extended desktop | High-quality DP cables on input and outputs |
Poor DisplayPort cables may cause:
- No video
- Flickering
- Black screen
- One monitor not detected
- Wrong resolution
- HDR not working
- Extended desktop not working
- Signal dropouts
For troubleshooting, test each DisplayPort cable directly between the source and monitor.
Power Requirement — Critical
The DP-102 requires external power.
| Power Detail | Value |
| Power input | DC 5V/1A |
| Power consumption | 2.2W max |
| Included power supply | 5V/1A power supply |
If the Power LED does not turn on, check the power adapter, outlet, and DC 5V connection.
Understanding SST Mode
SST stands for Single-Stream Transport.
Use SST mode when you want the same image on both monitors.
| SST Mode | Behavior |
| Display output | Duplicate / mirror |
| Monitor 1 | Same image as source |
| Monitor 2 | Same image as source |
| Best use | Presentations, mirrored displays, monitoring setups |
The manual’s SST application diagram shows a PC connected to the splitter and the same display content sent to Monitor 1 and Monitor 2.
Understanding MST Mode
MST stands for Multi-Stream Transport.
Use MST mode when you want two separate displays from one DisplayPort output.
| MST Mode | Behavior |
| Display output | Extended desktop |
| Monitor 1 | Independent display |
| Monitor 2 | Independent display |
| Best use | Workstations, multitasking, trading desks, productivity setups |
The manual’s MST application diagram shows a PC connected to the splitter and different content on Monitor 1 and Monitor 2.
Understanding Panoramic / Video Wall Mode
The manual lists support for panoramic video wall configurations.
This can be used when the source GPU and display settings allow a wide desktop or grouped display arrangement.
Common uses include:
- Gaming simulation setups
- Control rooms
- Command centers
- Large desktop workspaces
- Digital signage walls
- Professional visualization systems
GPU software such as AMD Eyefinity, NVIDIA Surround, or Intel Collage may be required depending on the setup.
Understanding DSC
DSC stands for Display Stream Compression.
The DP-102 supports DSC, which helps DisplayPort carry higher-resolution video within available bandwidth when supported by the source and display.
For DSC to work, the DisplayPort source device and monitor must also support DSC.
