Sony KDL-40HX723 review


Sony's EX723 series turned out to be some of the worst 3D performers we've seen, but subsequent 3D models have upped the brand's game. On paper at least, this set looks equipped to do the business. It carries MotionFlow XR 400 processing; a system that...

Mostly very good 3D pictures; excellent 2D pictures; Sony’s BIV online system is superb

Residual 3D crosstalk in dark scenes; more than a little overpriced

Sony KDL-40HX723 - Pocket-lint


Sony TVs are a bit like Star Trek movies. They alternate between good and woeful for no apparent reason. But while the decent Trek flicks are relatively

Crisp, convincing HD images; bright ‘outy’ 3D; well-stocked streaming media portal

No support for MKV, no 3D glasses included

While we wish Sony would support MKV media playback, we can’t complain about the audiovisual quality of this screen. Offering an admirable HD performance, active shutter 3D that doesn’t fatigue and a galaxy of IPTV, it’s the star turn in Sony’s current...

Sony KDL-40HX723 review


Edge-lit LCD with superb 2D and 3D pictures and the excellent Bravia Internet Video service

Excellent Bravia Internet Video service ; 3D and 2D picture quality ; Multimedia support

Relatively high price ; No 3D specs included ; Minor crosstalk during dark scenes

The KDL-40HX723 has an ace up its sleeve with the potential to improve dramatically on the poor 3D efforts of the EX723 series. Motionflow XR 400 claims to deliver a processing-driven equivalent' of 400 frames per second, which ought to bode well for...

Sony KDL-40HX723


Strong smart TV content offering, natural, subtle picture, good detail, solid Freview HD tuner

Colours lack punch and dynamics

A super-smart TV thanks to a wealth of video content and Sony frills – and it’s only let down by a lacklustre colour palette

Sony KDL-40HX723 review


For this review we tested the 40in model in the HX723 range. It's also listed in a 46in screen size (KDL-46HX723) on Sony's website, but wer can't find the larger version for sale at present. That model has identical specifications except for its...

It's expensive, but this is a fantastic LCD all-rounder that has all the features we would expect and excellent image quality

It's expensive, but this is a fantastic LCD all-rounder that has all the features we would expect and excellent image quality

Thanks to its excellent specification, great image quality and superb 3D playback, the HX723 is easily one of the best all-round LCD TVs we’ve seen. The quality comes at a price, though, as £700 is a lot to pay for 40 inches. However, if you have a...

Sony KDL-40HX723


After its disastrous EX723 series, Sony badly needed a 3D winner. And in the 40HX723, that's exactly what it's got.

Very good 3D and excellent 2D pictures ; Peerless online video service ; Superb upscaling

Tricky to use ; Rather expensive ; No 3D glasses included

Well would you believe it, Sony can produce a good 3D picture after all. In fact, the quality of the 40HX723’s 3D pictures make the problems with the EX723 range look even more like some kind of manufacturing flaw. The 40HX723 is also an excellent 2D...

Sony KDL-40HX723 40in LED 3D TV


Review The KDL-40HX723 is a feature-heavy 40in Freeview HD TV from the posh end of Sony's 2011 catalogue. While it sells for a tad more than a looky-likey from the brand's bread and butter EX range, the premium is worth paying if you want to see what...
