The Sony Bravia KDL-40HX723 is the 40'' version of the Sony Bravia KDL-46HX723 TV that we tested.

It has a PVA display manufactured by Samsung-Sony with a semi-glossy finish and Edge LED backlighting.  It features another of other services, including support for the DLNA standard and a rather disappointing media player which can only handle FAT32 devices and a rather small selection of file formats.

When we tried it out in our lab, the display turned out to be very responsive with a ghosting time of just 10 ms.  It has great colour reproduction (the deltaE is 2.6), almost-perfect gamma and an excellent contrast ratio of 3760:1.  Another point in its favour is that, unlike the majority of TVs with Edge LED backlighting, it suffers from relatively little clouding.

For audio, the HX723 is just about average.  The speakers are powerful enough for watching TV programmes, but the lack of decent bass can be a problem with films.

Everything we said in the original article holds true--the only thing that's different is the size!

The only exception is that some manufacturers fit different sized televisions with panels from different sources. In that case, our comments are only valid for the panel that we originally tested. Contrast, black levels, colour handling and ghosting are all subject to change from one panel to another.

Manufacturers who do fit the same panel in all of the TVs in a range can expect the same results across the whole range. The only factor which could be prone to slight variation is the brightness, producing slightly different contrast. According to our own tests, and assurances from manufacturers, the results of one TV can accurately be applied to others in the range.

4/5 Sony Bravia KDL-40HX723 DigitalVersus 2011-11-21 10:14:00

Pros

  • Accurate colours in Custom mode: deltaE: 2.6
  • Great contrast ratio: 3760:1
  • Powerful motion interpolation filter
  • Low energy consumption: 72 W

Cons

  • Big problems with crosstalk in 3D
  • Viewing angles too narrow
  • Media player doesn't support enough formats
  • Visible clouding on our test unit

Conclusion

The HX723 TV performs almost identically to its younger brother, the EX723. They're so similar, in fact, we're not sure what the point in this new model is. Its only real advantage is that the version we tested suffered from a little less clouding.
