Execute a monitor power cycle

Change the monitor
If nothing else works, changing the monitor is the only option left. If nothing, changing the monitor will at least narrow down the list of probable reasons why the HDMI to DisplayPort conversion is not working.
If everything is alright with the new monitor, then this means that the old one was damaged. If the connection doesn’t work with the new monitor as well, then there is a problem with the cables or the adapter.
Check for physical damage
Inspect the HDMI and DisplayPort ports and cables for any physical damage. Bent or broken pins can cause the connection to fail. Cracks in the connectors or ports, or missing or damaged plastic parts are often the cause for the conversion to not work. Even small nicks and scratches on the connectors can affect the connection quality.
If you find any physical damage, replace the cable or adapter. To avoid damage, handle the cables and connectors carefully and avoid pulling or twisting them. Here is an article on how to properly store your cables.
