Most modern laptops come with an HDMI port, which is usually located on the side or back of the device.

However, not all laptops are created equal when it comes to HDMI compatibility. Some laptops may have limitations on their HDMI ports, such as:

Refresh rate limitations: Some laptops may only support a certain refresh rate, such as 30Hz or 60Hz, while others may support higher refresh rates like 120Hz or 144Hz.
Audio limitations: Some laptops may not support audio output through the HDMI port, or may only support certain audio formats.
