NTI DP-HP-MNTR-SRC DisplayPort 1.4 Hotplug Maintainer
The DP-HP-MNTR-SRC manages communication between a DisplayPort source device (e.g., computer) and sink device (e.g., monitor) with the purpose of maintaining the screen settings in the event of the sink device being disconnected. One application of this device is to resolve screen resetting issues when employing a DisplayPort KVM to actively switch between two sources and a single sink. By installing the DP-HP-MNTR-SRC in series with the source and KVM, the source will see a constantly connected sink and will therefore maintain the screen setting when the KVM user selects the other channel.
Features
- Emulates a DisplayPort display (sink device) by providing Hot Plug Detect to the DisplayPort source device.
- Designed for use with KVM/video switches.
- When the input channel is deselected, the host computer connected to that input channel via the DisplayPort Hotplug Maintainer will recognize the monitor as connected.
- Eliminates the need to reconfigure monitor settings – keeps screen settings while switching to another computer and then back.
- Supports all source and display resolutions, including Ultra-HD 8K (7680×4320) @30Hz, 4Kx2K (4096×2160 and 3840×2160) @60Hz, 2560×1600 (WQXGA), 2560x1440p (WQHD), and HDTV 1080p @120Hz.
- The Hotplug Maintainer is completely transparent.
- DisplayPort features supported:
- DisplayPort v1.4
- Multi-Stream Transport (MST)
- 10-bit Color / 30-bit Deep Color
- RGB, YCC 4:4:4, YCC 4:2:2

Installation
Connect to Your Application
The DP-HP-MNTR-SRC is outfitted with a full-size DisplayPort plug and
receptacle. The plug is to 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.
The recommended installation procedure is as follows:
- Power down all equipment
- Install the DP-HP-MNTR into the source port.
- Connect all cabling
- Power up the monitor
- If there is any, power up mid-stream equipment (e.g., KVM Switch)
- Power up source. If there is a KVM switch, ensure that the KVM is set to the source that is being powered
- Once the source is fully booted and an image is displayed, the DP-HP-MNTR-SRC is functioning. The KVM Switch (if any) can be switched and other sources can be powered.

Tip: When a computer turns OFF the display or goes to sleep, it will stop providing power on the video output ports and the DP-HP-MNTR-SRC will power OFF. As a result, windows may be resized and moved after the PC “wakes up” and starts to display again. To avoid the issue, it is recommended to disable the sleep mode and set the computer to not turn OFF the display. If you are running Windows, related settings are found in “Power Options”.
