The technology powering our computers and televisions alike has evolved significantly over the past several years. Now, more than ever before, individuals have to the ability to use their computer hardware in tandem with their televisions, expanding the viewable display area for their computer in the process. This convenience is due in large part to the implementation of High-Definition Multimedia Interface, or HDMI, technology. Understanding how to route HDMI from computer hardware to TVs will help ensure that you have the best possible experience with your cutting-edge devices.
The Basics of HDMI
HDMI was first introduced in 2002 as a means of sending uncompressed video data between two devices. Since its implementation, HDMI has fast become one of the most popular forms of media transfer in existence today. This is also due to the fact that the technology powering HDMI can be obtained quite affordably. HDMI ports are now a de facto standard on devices ranging from computer monitors to TVs and video game consoles.
HDMI connectivity relies on the use of a compatible HDMI cable. HDMI cables consist of two identical ports, completely removing the need for male/female connector designations. The cable itself is composed of twisted pairs of cables that are also shielded. There are four pairs of these cables in each standalone HDMI cable.

PC Cables and HDMI
The vast majority of modern computer hardware relies on either HDMI or USB technology to power media transfer today. With that in mind, computer users who are seeking to connect their new PC to an HDMI TV will likely not need to rely on a VGA to HDMI cable or something similar.
In order to effectively make the connection between these devices, the first step is to locate the HDMI port on both your computer and your TV. In some situations, your HDMI TV may have multiple HDMI inputs. In this case, pay careful attention to which specific port you use, as you will need to select this as your designated input at a later stage.
Once you have located the ports, use an HDMI cable to connect your computer to your TV. If you encounter any difficulties when plugging the cable into the ports, stop completely and check for obstructions. Under no circumstances should you attempt to force the cable into the port, as this could damage the internal workings of both your TV and computer over time.
Sending HDMI From Computer to TV
Once your cable has been connected, the next step is to power on both devices. Your computer should immediately detect the presence of the HDMI cable and start routing the display to the newly connected TV. That being said, you will likely need to select the specific port on your HDMI TV in which the HDMI cable is connected. This can be done using the "Source" or similarly worded button on your remote or TV. After locating your source options, select the current port hosting the HDMI cable in order to receive video signals from the computer.
In the event that connecting an HDMI laptop to your TV is not working, you may need to review your computer's system preferences. There is a chance that your computer has not automatically routed video signals through the HDMI cable. This means that you will need to manually select the HDMI port as your intended display source within the display settings of your system preferences.
