I'm eager to find out how a smaller set fares with the Ideal Lume.
Smaller monitors actually need bias lighting the most. "Smaller" really should be understood as any monitor that occupies a smaller portion of the observer's field of view. If you sit far enough away from a 65" screen, it can occupy the same portion of your field of view as a 15" desk top computer monitor.
One of the reasons movie theaters don't use backlighting is the size of image provided. The other reason is the comparatively dim image (8 to 12 ftL). A small, bright, TV or computer image, in a dark viewing environment, needs bias lighting to prevent viewing fatigue and eyestrain.
Best regards and beautiful pictures,
