Key specification

LED

LCD and LED TVs differ only in the way the screen is illuminated. A handful of backlight lamps light-up a traditional LCD display, on ‘LED TVs’ the lamps have been replaced by hundreds of smaller LEDs (light emitting diodes). LEDs are also more energy efficient than traditional bulbs. Plasma TVs do not have backlights but illuminated by the brightness of individual gas cells.

40"

This is the size of the screen in inches, measured diagonally across.

Freeview HD Freesat HD DVB-S2 - general purpose satellite tuner

The type of built-in digital tuner. Dual HD tuners have both Freeview HD and Freesat HD – but the tuners operate separately, not in conjunction. So for instance, you can’t watch one channel on Freesat and record another on Freeview.

Yes

All the fill-size TVs we review are ‘HD-ready’ and suitable for watching 1080i HDTV broadcasts via Sky, Virgin or Freesat. The ‘HD-ready 1080p’ logo means the TV has a 1,080 line screen resolution, and can process a 1080p/24 signal used on Blu-ray DVD movies – although this is not a guarantee of the best HD picture. Older ‘HD-ready’ sets will switch to a 1080i picture when used with high-definition DVD, but are more likely to suffer from a slight picture judder on panning shots.

yes

The TV is capable of displaying 3D broadcasts from Sky or Virgin and 3D Blu-ray movies. 3D glasses are sometimes sold separately.

yes

Specifies if the unit has Smart TV capability

1

Socket for plugging in headphones.

1

Scart sockets are the standard way to connect recording devices, DVD players, and set-top boxes. RGB is the highest quality video signal that can be carried on a Scart and is your best bet for a good picture.

0

Means you can view photos from various digital camera memory cards on the big screen. High resolution digital photos viewed this way usually look very good.

Yes

Some Smart TVs come with built-in Wi-Fi, but most connect wirelessly with the addition of a wifi USB dongle (sold seperately).

yes

The number of ethernet connections

Not tested

A VGA input can be a handy option for connectiong a computer or laptop to the TV, although using an HDMI connection is preferable if it's possible.

Energy use

73.70

Based on using our viewing panel’s ideal picture settings. Settings are aimed at getting the best picture, but typically mean it uses less energy too. An energy efficient 40-inch LED should use around 60-70 Watts. Larger 42-inch plasma TVs will use more than twice that amount of energy.

50.00

Energy consumed with energy saving picture setting activated (typically involves dimming the backlight).

19.50

Based on TV switched on for 5 hours a day and left standby for the rest of the day. Electricity priced at 14.5p per k/W.

0.05

During standby after 2 hours and/or using ECO mode. Ideally this should be below 2 Watts to meet the Energy Saving Trust recommendation.
