Inappropriate refresh rate: It is a software issue that may lead to the DisplayPort not detected issue as well. In the fourth quarter of 2009, VESA announced that the Mini DisplayPort had been adopted. All devices using the Mini DisplayPort must comply with the 1.1a standard. It was announced by Apple in October 2008, and by early 2013 all new Apple Macintosh computers had Mini DisplayPort,  as did the LED Cinema Display.   However, in 2016 Apple began phasing out the port and replacing it with the new USB-C connector. The Mini DisplayPort is also fitted to some PC motherboards, video cards, and some PC notebooks from Asus, Microsoft, MSI, Lenovo, Toshiba, HP, Dell, and other manufacturers. If the graphics card driver on your computer is not the latest build, you may also counter the display port no signal issue. You can fix it by updating the device driver to the latest version.

Unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 ( WQXGA) in its DisplayPort 1.1a implementation, and 4096×2160 ( 4K) in its DisplayPort 1.2 implementation. With an adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.    Compatibility [ edit ] Apart from the software issues, the hardware issue can also lead to the “no dp signal from your device” issue. If all the above methods fail to work, you may consider switching to another cable and device. You can test the DisplayPort connection on another DisplayPort cable or on another computer and monitor.

While the DisplayPort specification can support digital audio, the older 2009 line of MacBooks, MacBook Pros, and Mac Minis cannot provide an audio signal through the Mini DisplayPort, and only do so over USB, Firewire, or the audio line out port. (The April 2010 line of MacBook Pro, Mid 2010 MacBook, and July 2010 iMac and later do support this ). This can be a problem for users who want to connect their computers to HDTVs using a Mini DisplayPort to HDMI adapter. To work around this issue, some third-party manufacturers have created dual or triple-headed adapters that get power for the adapter from a USB port, video from the Mini DisplayPort, and audio from either the USB port or the optical-out port. Either option terminates with a single female HDMI connector, thus allowing both video and audio to be channeled over the single HDMI cable.  Apple's Dual-Link DVI or VGA adapters are relatively large and expensive compared to past adapters, and customers have reported problems with them, such as being unable to connect to an external display. Monitors connected to a Mini DisplayPort via these adaptors may have resolution problems or not "wake up" from sleep.   The simplest and fastest method to fix the display port no signal issue is to restart and reconnect your device. Here’s how to do that:
