Dual Play requires the use of two sets of special 3D glasses, LG F310DP, sold separately in a bundle.

The “Plus” is Local Dimming
One of the main contributing factors to amazing clarity and color detail is contrast. Contrast affects how deep and “inky” blacks appear and how warm and rich colors appear on-screen. The 55LA7400 incorporates local dimming to increase the contrast of light and dark images on-screen. The result is more color detail and amazing clarity regardless of the content being watched on-screen. LED Plus separates the pixels of the display into “zones” which are then monitored by on-board sensors that dim the backlights in “zones” that have darker images than the rest of the screen.
