To connect a device to an HDMI display, you can use a DisplayPort to HDMI adapter or cable if your device has a DisplayPort output, and then plug the HDMI cable into your TV or monitor. Once connected, you can configure your display settings on your computer to either duplicate or extend your screen.
Step-by-step guide
Connect the adapter/cable: Plug a DisplayPort to HDMI adapter or a direct DisplayPort to HDMI cable into your computer's DisplayPort (or Mini DisplayPort) output.
Connect the HDMI cable: Connect an HDMI cable from the adapter or the end of the cable to the HDMI input on your TV, monitor, or projector.
Select the source on your TV/monitor: Use your TV or monitor's remote control to change the input source to the HDMI port you plugged into.
Adjust display settings on your computer:
On Windows, press the Windows key + P to open the display options.
From there, you can choose to "Duplicate" your screen, "Extend" it to the new display, or "Show only on the second screen".
Things to remember
Adapter vs. cable: You can use either a DisplayPort to HDMI cable or a DisplayPort to HDMI adapter with an existing HDMI cable. The adapter is useful if your computer has a DisplayPort and your TV has an HDMI port.
Resolution: Most standard adapters support resolutions up to 1080p (Full HD), and newer ones can support 4K resolution, but it's best to check the adapter's specifications.
Direction: A DisplayPort to HDMI adapter is not a bidirectional device, meaning it only works in one direction: DisplayPort to HDMI. It will not convert an HDMI signal to DisplayPort.
Plug and Play: Most adapters are plug-and-play, meaning they don't require any additional software or drivers to work.
