If you are staring at a blank screen, your problem could be that DisplayPort is not detecting the monitor.
DisplayPort is a royalty-free digital display that supports 8k display at 120 Hz, GSync and Multi-stream Transport. Furthermore, it is backward compatible with other display interfaces, including VGA, DVI, and HDMI.
The other widely adopted display interface standard these days is HDMI. However, HDMI can only support 4k 30fps resolutions, and it doesn’t have support for GSync yet. Likewise, DP also supports Multi-stream Transport (MST), which allows you to connect multiple displays to a single DP port in your computer, whereas HDMI does not support this feature. Using DP over HDMI has started gaining traction in recent times, especially now that DisplayPort over USB C is becoming prevalent.
Sometimes, your DisplayPort connection to the monitor will not work due to bad cables, driver issues, etc. If you are having problems with DisplayPort not detecting your monitor, there are a few ways to troubleshoot this issue.
