Sony KDL-HX750 review: Sony KDL-HX750

Smart TV: I've personally been a fan of the XMB since it debuted on the PlayStation 3 and personally find it very easy to navigate. The HX750 has the modified version that appeared in last year's TVs and supports picture-in-picture. From here you can access on-demand apps like Netflix -- there's a superb selection -- and Sony's own Entertainment Network, which makes the inclusion of the next feature puzzling.

The SEN (Sony Entertainment Network) button on the remote brings up a second interface that lets you access the same features above but in a more condensed way. The headings are divided into Movies, Music and Apps (which you can already access from the XMB). Launching a separate application in this way is an unnecessary duplication -- who wants to leave a user interface for another interface that essentially does the same thing? The SEN is obviously designed to sell video and music content directly, but I couldn't see myself using it very often unless I had a SEN subscription.

Picture settings: The Sony offers a number of different picture presets for users, which includes the excellent Cinema mode. While we were able to tweak the TV using the few advanced calibration tools the default mode is pretty good already. If you want to tinker, the TV does offer limited grayscale controls and a few gamma presents but nothing as advanced as Samsung or LG.


The TV boasts a modern complement of ports, including four HDMI.

Connectivity The four HDMI ports and two USBs are standard for a modern TV. There's also a component/composite port and a second for composite video only, along with an analog VGA input for computers.

Picture quality

Just as with the EX720 before it, the HX750 has very accurate colors in mid-to-bright areas and it was able to keep pace with our color reference, the 2011 Samsung D7000 plasma . Shadow detail was very good with little crushing, and contrast was also more natural compared with the Vizio M3D, which showed flattening of the white areas and too much punch. The HX750's good points were over- (under-?) shadowed, however, by lighter black levels than our comparison models, causing its picture to look somewhat washed out.

Black level: At what price can you expect superior black levels? Well, last year it was about $2,500 for the VT30, but this year inky blacks can be had for as little as $1,500 in the astounding ST50. So where does this leave the HX750? Well, let's just say that a boat without a paddle is involved.

Even when compared with the last year's Vizio -- also $500 cheaper -- the Sony can't get that eye-popping depth that deeper blacks can bring. Due to some color problems in the bottom of the color spectrum, some of the inkiest shadows are purple rather than black. But at least it doesn't obliterate details as much cheaper sets, such as Insignia and TCL , can do.

Color accuracy: The colors on the HX750 are some of the best we've seen on an LCD for some time. Flesh tones can be too rosy or washed out on some TVs, but here they're spot-on. Other colors looked natural especially in comparison with most of with the other TVs in the lineup. We had to do very little adjustment to give an almost reference-level performance in the mid- and bright tones, but the dark colors were another matter, with near blacks becoming slightly purple.

Video processing: The TV was able to handle itself well in our image processing tests with good showings in 3:2 pull-down and deinterlacing 1080i material. The MotionFlow Engine was able to remove judder from most material without artifacting and give a perfect 1200 on our motion resolution test. Our only issue was with the new Impulse mode: not only does it reduce the brightness significantly and introduce flicker, watching it is a little nauseating.

Uniformity: As an edge-lit screen, the television does have some issues with screen uniformity with lighter blotches in the corners, though less noticeable than on some recent TVs. Turning down the backlight helps a lot, but during dark movies they can become a little distracting.

Bright lighting: Not truly matte, the TV does have a slight gloss to it in comparison with the Vizio M3D550SR, but even in a lit room with some direct light we had no issues watching most program material.

3D: Sony has staked its recent reputation on the quality of its 3D, and while the HX750 is better than last year's NX720, it's not quite a market leader. Our test scene from the sumptuously photographed "Hugo" involves the child approaching the toymaker at his work bench and reaching out a ghostly hand for a toy mouse. The slow, deliberate movement gives most TVs a run for their money, as the hand is quite forward in the 3D viewing space and highly contrasting. The Sony wasn't able to render the scene without a little crosstalk, though it was muted and better than on the ST50, for example, and it's only on contrasting images that you will see any real issues.

While Sony is part of the official forum that supports a unified 3D standard, the TV also needs to support it, which unfortunately the Sony HX750 doesn't.
