HDMI uses a data protection protocol called High-bandwidth Digital Copy Protection (HDCP).īoth HDMI-connected devices must comply with HDCP, recognizing and authorizing each other as the sender and receiver of signals.Īfter recognizing the receiver as a non-recording device and complying with HDCP, the sender will encrypt data to transfer via the HDMI cables. One of the initial purposes of HDMI was to protect digital content from unauthorized copying. HDMI is even compatible with DVI, so you can use an HDMI-to-DVI adapter if one of your devices only has DVI and the other only has HDMI. In addition, HDMI ports are future-proof, meaning they have enough spare bandwidth to cover future technology. However, they’re all backward compatible, and you can plug a lower version cable into a higher version port as long as you don’t mind the quality loss. Since the introduction of HDMI in 2002, several versions have emerged and offered higher resolutions and better features than previous ones.Įach port requires a matching cable to deliver the highest quality promised. New models of HDMI ports can transfer ethernet signals, making them even more versatile. Not every TV has wireless connectivity, while almost all modern TVs made after 2014 have HDMI ports. You may be able to replace HDMI connectivity with wireless connections like Bluetooth and Wi-Fi. This versatility allows you to use only one cable to connect many devices without worrying about quality loss. That means you can even project the contents of your smartphone or tablet on your HDTV. HDMI cables allow you to connect any smart device to a display. That’s an excellent advantage for those who watch their movies on Ultra HD displays and want the highest video and audio fidelity. Newer generations of HDMI cables can transfer 8K and even 3D video and uncompressed digital audio in addition to Dolby Digital Plus and Dolby TrueHD. Thanks to its digital technology, the audio and video signals are transferred as ones and zeros instead of physical waves.Īs a result, there’s little to no signal loss during data transfer, allowing you to get high-resolution audio and video.Įven if there’s a signal loss, the receiving device can compensate for it thanks to its technology. Not only can HDMI transfer dual signals, but it also does it without compromising quality. HDMI solved this issue by transferring audio and video signals through one cable, helping declutter workspaces and simplify things. Without HDMI, it isn’t easy to connect smart devices and displays because of the following advantages that other connections can’t provide.īefore HDMI came along, the connection types could only transmit one type of signal: audio or video.Īs a result, you needed two cables and ports for each signal. HDMI connections are so practical that they have become a determining factor when purchasing display devices. If you want to buy a new monitor and aren’t sure about its HDMI ports, you can check its specs sheet or visit the manufacturer’s website. Some monitors may have the HDMI port on the side of the panel to allow for better access. You can easily check the back of your monitor to see the number of its HDMI ports. They’re so common that some monitors come with more than one HDMI port to give users more flexibility in connecting devices. Most, if not all, modern monitors feature HDMI ports because it’s an industry standard commonly used in many devices. One of these connection types is the HDMI port, which has been around for a long time, offering a reliable and convenient connection.ĭo you need to consider HDMI ports when choosing a monitor, or do they come as standard equipment? With the expansion of digital technology in our lives, we may need to connect many devices to our monitors. The connection ports may not be as important as resolution or price, but they must be on top of your priority list.Ĭonnection ports are essential because we rarely use our monitors as standalone devices. If you’re in the market for a monitor, you must consider a wide range of factors.
