Does it matter what HDMI cable I get?
The answer to this question is not a simple yes or no, as it depends on various factors such as the resolution, refresh rate, and bandwidth of your devices, as well as the distance between them, and whether you need special features like Dolby Atmos or Dolby Vision. In general, a high-quality HDMI cable can make a noticeable difference in video and audio quality, especially when it comes to 4K and 8K resolutions, but an expensive HDMI cable does not necessarily produce richer colors or crisper sound than a cheaper one.
Understanding HDMI Cables

The most common types of HDMI cables are Standard, High Speed, Premium High Speed, and Ultra High Speed, each with its own set of specifications and capabilities.
