There are also recurring complaints about minor software annoyances like laggy menus and input names resetting.

The 'evo AI' part means it has a brighter panel and a smart processor that uses artificial intelligence to make everything look and sound better, adapting to what you're watching. For gaming, the refresh rate and HDMI 2.1 ports are critical for smooth, responsive gameplay at high resolutions.
