Ans: In case, your current HDMI cable has an older version (like HDMI 1.4), then you need to upgrade to an HDMI 2.0 or higher version to support the 4K resolution in your 4K TV or 4K capable devices. Here the latest HDMI 2.0 version will offer faster data transfer rates, and higher bandwidth required for 4K content to elevate a seamless & high-quality viewing experience.
