Motion Processing
Manufacturers now use their own measurements so can not necessarily be compared between brands. Examples include LG - Motion Clarity Index (MCI), Samsung - Clear Motion rate (CMR), Philips - Perfect Motion Rate (PMR), Sony - Motionflow XR and Panasonic - BLS (Back Light Scanning). All these figures are twice or more than the traditional 100Hz/200Hz refresh rate figures. No abbreviation indicates traditional measurement. Plasmas generally use a 600Hz sub-field refresh rate.

LED Backlight
Does the TV have LED backlighting and what type is used? Full Array LED is generally agreed to be the highest spec and offers very even lighting and slim depth. Edge LED keeps a slim depth but relies on more processing for even lighting. Direct LED is the most basic and has the deepest depth. A simple 'Y' means the LED type is unspecified at present.

Local Dimming
Full Local Dimming or Full Array Local Dimming is available on top spec LED screens with Full Array LED backlighting. This allows for 'pockets' or 'zones' on the screen to be individually dimmed, giving greatly improved contrast between light and dark images. Edge and Direct Local Dimming gives some of the benefits of Full Local Dimming but not usually to the same standard. OLED offers the best results with individual pixel dimming.

Twin Tuners

OLED
OLED (Organic Light-Emitting Diode) TV offers perhaps the most advanced picture quality. Unlike more basic LED screens, OLED doesn't require backlighting. This helps the screens be thinner, lighter or even curved. They are also more consistent in the colour they produce, with higher contrast levels, too.
Curved Screen
By using a curved screen the viewing experience is more natural and everyone in the room gets to see the benefits of a superior viewing angle.
