Hello there. Thank you for sharing your inquiry with us. We understand your question regarding the potential for dimming when the LG OLED B5 series (OLED55B5PUA) is connected to a PC, similar to what you may have heard about the C1 model. The dimming you are referring to is typically related to two features present in most OLED TVs: ABL (Automatic Brightness Limiter): This is a hardware protection feature that manages power and heat by dimming the entire screen when a large portion of it is very bright (high Average Picture Level). ABL cannot be disabled through standard user menus as it is essential for the panel's safety. ASBL (Auto Static Brightness Limiter) / TPC (Temporal Peak Luminance Control): This is a feature designed to prevent image retention (burn-in) by automatically dimming the screen after a few minutes if it detects a static image, such as a desktop with unmoving elements. While ABL is an inherent safety function of OLED technology and will be present, the implementation and aggressiveness of ASBL has been improved across generations of our OLED TVs, which helps to minimize the noticeable dimming effect during PC use compared to older models. For PC and console users, the OLED55B5PUA includes features like the Game Optimizer and dedicated Game/PC modes which are designed to enhance your experience by automatically applying settings to reduce input lag and optimize picture quality for a computing environment. https://www.bestbuy.com/product/lg-55-class-b5-series-oled-ai-4k-uhd-smart-webos-tv-2025/JJ8VPZTKH9 If you have any further questions about optimizing your settings for PC use on the OLED55B5PUA, please send us a private message on Social Media @LGUSSupport, and our team will be more than happy to assist you. —Renzo
