Samsung and Best Buy are facing a class action lawsuit in the US over allegations that some Samsung QLED 4K TVs lack advertised features. A lawsuit filed by Ray Kim Lowe in Central District Court of California alleges that some TVs sold by the company and retailer are missing Motion Xcelerator Turbo+, FreeSync, and HDMI 2.1 ports.

Missing features: Motion Xcelerator Turbo+, FreeSync and HDMI 2.1 ports

The lawsuit highlights the lack of Motion Xcelerator Turbo+, a feature on some QLED TVs designed to increase the frame rate of content by adding new frames between existing ones. This feature provides smoother playback and smoother viewing. It’s also missing AMD’s FreeSync technology, which synchronizes the screen’s refresh rate with the content’s frame rate to eliminate screen tearing and flickering.

Another advertising feature missing from some models is HDMI 2.1, the latest version of HDMI. HDMI 2.1 supports higher resolutions and frame rates, allowing content up to 4K resolution at 120 frames per second or 8K resolution at 60 frames per second. Even TVs with a 60Hz refresh rate are often equipped with HDMI 2.1 ports, as it has become a common industry standard.

Specific details regarding the affected Samsung QLED 4K TV models have not been disclosed at this time. More information is expected to emerge in the coming days as the story unfolds. Potential buyers of a Samsung TV are advised to check the advertised features before purchasing.
