Q: Can the tv be turned on without remote control
A: Hello Hisense Customer, Thank you for your interest in the Hisense 55U6SF. This model features a physical power button that is located at the bottom center of the unit. Thanks again, Harley with the Hisense Support Team.
Q: What is the difference between this, the 55U6SF, and the 55U6SF PRO?
A: Hello 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.
A: Hello Victor, thank you for choosing the Hisense 55U6SF and for sharing your feedback with us. We are truly sorry to hear that the unit is power cycling. This isn't the home theater experience we want for our customers. But rest assured, this model is covered by a one-year manufacturer warranty. Please reach out to our dedicated support team directly at 1-888-935-8880 or via email at [email protected] so that we can promptly address and resolve the issue for you. Thank you, Harley with the Hisense Support Team.
A: Hello Hisense Customer, Thank you for your interest in the Hisense 55U6SF. This model operates on the Fire TV system. We recommend one of our Roku models, such as the 55H5BR. Thanks again, Harley with the Hisense Support Team.
