With the LG I'm about a meter or less away from screen and use window management tools to pull focus to the center lower section for any focused work. I run Win 11 from an RTX3080 card with a 2.1 HDMI cable. 3840x2160 120Hz.
For gaming I just use windowed mode and use the full width of the 65" but just the lower half usually for COD or FPS games. I don't notice any eye strain or other issues but do run everything I can in dark mode including using the browser with the Dark Reader extension.
