Sony Bravia KDL-40EX720


A notch larger than the 32-inch KDL-32EX720, the Sony Bravia KDL-40EX720 is a 40-inch edge-lit LED HDTV with 1080p video in both 2D and 3D.

The Sony KDL-40EX720 ($1299 MSRP) is an LED-edgelit LCD capable of 3D display. These second-gen 3D TVs are finally coming down in price, but we're still not sold on the whole headache & eyestrain thing. That said, this TV has a great core performance...

This is a review of the Sony KDL-40EX720. Test results were derived from the 55-inch version, the KDL-55EX720, but should indicate the general performance of other sizes in the series. The xxEX720 series includes the following models: KDL-32EX720,...

Sony KDL-40EX720 Review – 40-inch LED LCD HDTV


Sony has as usual excelled in adding these new models to this year's line-up. This 40-inch set will not fail to impress you with its features despite its small size. Even though this TV may not make it to your living room, yet it is a good choice for...

The Presence Sensor is another feature which keeps the energy usage low. This sensor can detect movement in the room. Hence, if no one is there in the room, it will turn off the picture, leaving the sound on. If you don’t come into the room for a long...

Sony Bravia KDL-40EX720


The Sony Bravia KDL-40EX720 is a decent smart TV that offers a good quality picture, but a spotty feature count for the money.

Decent blacks ; High-quality noise reduction ; On-board 3D sensor ; Good selection of IPTV content

Poor 3D mode ; Low motion detail ; Hollow sound ; No wireless on-board ; No 3D glasses ; Contrast could be better

While the TV sits at the top of the company's EX range it lacks that certain sparkle helping it to stand out. Design-wise, the company is using last year's blueprints and picture quality isn't a huge step up on last year. While we like some of the new...

Expert review by : Tim Grey (



Sony's days at the top of the TV food chain may, for the moment, be behind it thanks to vicious competition from the likes of Samsung, but the company's still in the business of making top-notch tellies.

Great picture quality and colour representation; snappy looks

No built-in Wi-Fi; troubling browser interface

This more affordable entry in Sony’s BRAVIA line-up can rightly claim top picture quality, smart looks and broad connectivity, but its online offerings leave a little to be desired.

A great entertainment display!


This is a great entertainment display, reason I say entertainment display is because it does more than watching television! I bought this at the local company store for only $799.99+tax! I was looking for a new PC monitor with 3D and this one jumped...

Great TV!


I bought this television before the whole 240/120 hz question started. I was not happy regarding the perceived false advertising of Sony. Still not thrilled about it, but I can't complain like some. The picture has been fantastic since I made the...
