If your monitor has failed to autodetect the HDMI input, then you will have to do this manually. Go to your monitor’s display settings and select Input. Thereafter, select the HDMI option.

Update drivers

Outdated monitor drivers can cause much hassle to the user. So, you should make it a habit of updating the drivers regularly. Go to the brand’s website and then select the appropriate driver.

Execute a monitor power cycle

Unplug your monitor from all the input sources and wait for a few minutes before plugging them back in. This can reset the connection and fix any issues with the HDMI to DisplayPort conversion.

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.
