HDMI cables are necessary to connect many devices such as TVs, monitors, game consoles, soundbars and home theaters. However, they are often not included in the set, so you have to purchase them separately. Many people are faced with the question - how to choose the right HDMI cable? They differ not only in price, but also in length, standard, resolution of the transmitted image and its refresh rate.

What are the differences between HDMI cables?
First of all, it is worth knowing that HDMI cables differ in standard. The most popular is currently the HDMI 2.1 standard, which appeared on the market in 2017. It has really great capabilities - it is able to transmit images up to 120 frames per second (FPS) in 4K Ultra HD quality, and even in 8K quality at 30 FPS. Before it, the most popular was the HDMI 2.0 standard, which is capable of transmitting images up to a maximum of 60 FPS.
Most often, HDMI cables are divided into four groups in terms of data transmission speed:
- HDMI standard providing a transmission speed of 7.92 Gbit/s;
- High Speed HDMI allowing for a speed of 8.16 Gbit/s;
- Premium High Speed HDMI achieving a speed of 14.4 Gbit/s;
- Ultra High Speed HDMI transmitting data at a speed of 42.6 Gbit/s.
Is it worth choosing an HDMI cable that ensures the fastest possible data transmission? It depends primarily on its purpose. The latest generation of game consoles or advanced graphics cards may have high requirements, so in order not to limit their capabilities, it is worth investing in an HDMI 2.1 cable compliant with the latest standard. However, choosing a high-speed HDMI cable will not increase the capabilities of the equipment. HDMI 2.0 cables are intended for TVs and monitors that display images in maximum Full HD resolution.
What effect does an HDMI cable have on image quality?
The data transmission speed provided by HDMI cables is primarily important for the displayed image. Four classes of HDMI cables are able to achieve different resolutions visible on the screen.
-
The HDMI standard allows you to display images in a maximum resolution of Full HD with a refresh rate of 60 Hz ; - High Speed HDMI also allows the display of Full HD resolution at 60 Hz , as well as Ultra HD 4K at 30 Hz refresh rate;
- Premium High Speed HDMI is the maximum image resolution of Ultra HD 4K with a refresh rate of 60 Hz ;
- Ultra High Speed HDMI is capable of displaying images in 4K at 120 Hz and 8K at 60 Hz .
When choosing an HDMI cable, make sure it does not limit the capabilities of the equipment. Even the latest TV set will not display high-resolution images if the HDMI cable connected to it does not allow for fast enough data transfer. Refresh speed is also important - if your equipment is capable of displaying Ultra HD images at 120 Hz, choosing a faster HDMI cable can make a huge difference.
On the other hand, remember that TVs and monitors will not display higher image quality than their specifications allow just because of a high-speed HDMI cable. Models without the ability to display images in 4K resolution do not need the fastest transmission speed, which is why High Speed HDMI cables are mainly recommended for them.
What type of HDMI cable is best for your TV?
HDMI cables are most often chosen for TVs. If you are faced with such a choice, start by taking a look at the specifications of your own TV. Pay attention to the maximum displayed image resolution and screen refresh rate, and then choose a cable that does not limit these possibilities. The most frequently chosen are HDMI High Speed and Premium High Speed cables. Ultra High Speed cables are worth the price when used on devices that take full advantage of their capabilities.
When choosing an HDMI cable for your TV, also pay attention to the appropriate length. It is recommended to choose cables as short as possible, taking into account the arrangement of devices in your home. A longer cable not only means a higher cost, but also a slight loss in data transfer speed. Therefore, it is worth carefully measuring the required cable length before purchasing, so that you can enjoy the highest possible image quality and do not have any difficulties with aesthetically hiding a cable that is too long.
