What is the difference between this, the 55U6SF, and the 55U6SF PRO?
Answered by HisenseProductExpertHello Oliver, Thank you for your interest in the Hisense 55U6SF. The Hisense 55U6SF‑Pro and the Hisense 55U6SF share several advanced features, but the Pro version is designed with higher‑end performance and display technology. The Pro model incorporates Mini‑LED backlighting with Hi‑QLED Color and achieves up to 1200 nits' peak brightness, making it superior for HDR content with Pro‑HDR compatibility. It also includes DTS Virtual:X audio in addition to Dolby Atmos, enhancing the sound experience. By contrast, the standard 55U6SF uses QLED Color without Mini‑LED, supports Quantum HDR, and emphasizes viewing comfort with an Anti‑Glare Low Reflection panel and Filmmaker Mode for cinematic accuracy. Both models feature a native 144Hz refresh rate with AI Smooth Motion, 144Hz Game Mode Pro, and the Hi‑View AI Engine, but the Pro version is tailored for higher brightness and more immersive audio, while the standard model focuses on reducing glare and preserving director‑intended visuals. Thanks again, Harley with the Hisense Support Team.
My 55 inch Hisense tv just shut itself off today I keep try to turn it back on and it blinks that red at bit then shuts back off. It almost came back on one time thought it was going to be ok but it finally just shut itself back off. Why?
