NTI DP-HP-MNTR-SRC DisplayPort 1.4 Hotplug Maintainer
Connects to Source/Computer
Product Overview
The DP-HP-MNTR-SRC manages communication between a DisplayPort source device (e.g., computer) and a sink device (e.g., monitor). Its primary purpose is to maintain the screen settings in the event of the sink device being disconnected. This device is particularly useful for resolving screen resetting issues when using a DisplayPort KVM to switch between multiple sources and a single sink. By installing the DP-HP-MNTR-SRC in series with the source and KVM, the source device will consistently detect a connected sink, thereby preserving screen settings even when switching to other channels.
Key Features
- Emulates a DisplayPort display (sink device) by providing Hot Plug Detect (HPD) to the DisplayPort source device.
- Designed for use with KVM/video switches.
- When an input channel is deselected, the host computer connected via the DisplayPort Hotplug Maintainer will recognize the monitor as connected.
- Eliminates the need to reconfigure monitor settings, preserving screen settings when switching between computers.
- Supports all source and display resolutions, including Ultra-HD 8K (7680x4320) @30Hz, 4Kx2K (4096x2160 and 3840x2160) @60Hz, 2560x1600 (WQXGA), 2560x1440p (WQHD), and HDTV 1080p @120Hz.
- The Hotplug Maintainer is completely transparent to the signal.
- Supports the following DisplayPort features:
- DisplayPort v1.4
- Multi-Stream Transport (MST)
- 10-bit Color / 30-bit Deep Color
- RGB, YCC 4:4:4, YCC 4:2:2
- LPCM
- HDR
- High-bandwidth HBR3
- Bandwidth up to 8.1Gbps per channel (32.4Gbps total)
- Compact design for easy installation and operation.
- No external power supply required; powered by the video source.
- TAA Compliant.
- Includes one 1-foot DisplayPort male-to-female cable (NTI# DP-PM-1-MF). This cable can be used in tight spaces or where connectors are too close together.
- Patent pending.
Diagram Descriptions
Diagram 1 & 2: PC/Video Source Setup
Illustrates a computer (PC) connected to the DP-HP-MNTR-SRC via its male DisplayPort connector. The female DisplayPort receptacle of the DP-HP-MNTR-SRC is then connected to a video splitter. The splitter distributes the DisplayPort signal to one or more monitors (e.g., HDTV Monitors).
Diagram 3: KVM Switch Setup with Multiple CPUs
Depicts a setup with two computers (CPU 1 and CPU 2). Each CPU is connected to a DP-HP-MNTR-SRC. The DP-HP-MNTR-SRC from each CPU is then connected via a USB Device Cable to a KVM Switch. The KVM Switch is further connected to a single monitor, a USB keyboard, and a USB mouse. A note indicates that each CPU will retain its specific resolution settings when switched through the KVM.
Diagram 4: Included Cable (DP-PM-1-MF)
Shows the included 1-foot (305mm) DisplayPort cable. It features a male DisplayPort connector on one end and a female DisplayPort connector on the other. Pinout details for both the male and female connectors are provided.
Installation
Connect to Your Application
The DP-HP-MNTR-SRC features a full-size DisplayPort plug and receptacle. The plug should be inserted into the video source port, and the cable connecting to the downstream KVM Switch should be plugged into the receptacle. The DP-HP-MNTR-SRC is powered by the DisplayPort source.
Recommended Installation Procedure:
- Power down all connected equipment.
- Install the DP-HP-MNTR-SRC into the source port.
- Connect all necessary cabling.
- Power up the monitor.
- If applicable, power up any mid-stream equipment (e.g., KVM Switch).
- Power up the source device. If a KVM switch is used, ensure it is set to the source that is currently powering up.
- Once the source is fully booted and an image is displayed, the DP-HP-MNTR-SRC is functioning correctly. The KVM Switch (if used) can now be switched, and other sources can be powered on.

Important Tip
When a computer turns OFF the display or enters sleep mode, it stops providing power to the video output ports, causing the DP-HP-MNTR-SRC to power OFF. Consequently, windows may be resized and moved when the PC "wakes up" and starts displaying again. To prevent this issue, it is recommended to disable the computer's sleep mode and configure it not to turn OFF the display. For Windows users, these settings are typically found in "Power Options".
