DisplayPort to HDMI adapter helps you connect your HDMI device to a DisplayPort-supported monitor. At times you may see aNo Signalerror when trying to connect your DisplayPort toHDMI adapterto your PC or monitor.
First, you should know that not all DisplayPort to HDMI adapters are reversible. In other words, if you buy a HDMI to DisplayPort adapter instead, which is cheaper, it might not work as a DP to HDMI adapter as well! So, make sure you’ve bought the right cable.
How do I get my DisplayPort to work with HDMI?
1. Check your HDMI and DisplayPort
If you see No Signal text on the screen when using the adapter, it could be due to a loose HDMI connection to the adapter or the DisplayPort interface.
Remove the HDMI cable connected to the adapter and plug it in again. Once done, make sure the HDMI cable connected to your PC is also firmly connected.
Be careful when applying pressure on the port, as it can damage the interface. If possible, try connecting the HDMI adapter to a different monitor or device. If it works, you may have a faulty HDMI port to repair.
2. Manually enable HDMI Input
At times your monitor may fail to auto-detect the HDMI connection, especially when you are using an adapter to convert DP signals to HDMI. Changing the input option manually can fix the problem.

As we have discussed in ourbest DisplayPort to HDMI adapters guide, not all the adapters are made the same. While most adapters can work with 1080p contents, very few adapters are capable of carrying 4K contents from your PC.
Try using your existing adapter with another system or monitor before you consider replacing the device.
4. Perform a monitor power-cycle
