Panasonic TX-L37DT30 Review - Online features and panel technology Review


The Viera Connect service mentioned earlier still feels a little like a work in progress if we’re honest. There are certainly plenty of good things about it, particularly its focus on meaty, video-laden services such as the AceTrax movie ‘store’, the BBC iPlayer, EuroSport, and YouTube.

But the surprisingly good quality games and intriguing health-related apps – with their associated optional extra hardware – we’ve seen at numerous trade shows are still nowhere to be seen, and the interface for accessing Viera Connect is already threatening to become cumbersome, even though the content level on the service isn’t currently all that high.

It’s also notable that there’s little evidence of any of the sort of small, limited-use ‘apps’ found in high numbers on 2011 LG and Samsung ‘Smart TVs’. Though some may feel that this is a blessing rather than a complaint!

Having described the panel technology in the L37DT30 as innovative earlier, we should briefly explain what these innovations are. Their main focus is on making the IPS Alpha panel (with its inherently wider viewing angle) respond fast enough to changing images to deliver alternate-frame 3D pictures without them suffering with crosstalk ghosting noise. So, for instance, a new, more fluid liquid crystal material has been used. Also, Panasonic has reduced the space between the screen and the backlight, which again allows the image to be refreshed more quickly. As if all this wasn’t enough, the L37DT30 claims to be 400Hz, via a combination of a scanning backlight and genuine 200Hz refresh rate.

Panasonic has caught the Imaging Science Foundation (ISF) bug in the past year or two, and so it’s no surprise to find its flagship LCD TV carrying ISF endorsement, complete with two ISF picture setting memory slots for use by the pro calibration group should you pay them to come in and optimise your screen’s performance.

Among the tools that have appealed to the ISF are a pretty good colour management system, and a degree of gamma control.

One last point to cover before finding out how the L37DT30 performs concerns its 3D glasses – or lack thereof. For normally the set doesn’t ship with any of Panasonic’s 3D glasses included in its price. You have to buy them separately. However, at the time of writing, two pairs were being included for the price quoted at the top of this article by

As hoped, it doesn’t take long watching 3D on the L37DT30 to feel that the impressive 3D efforts of the smaller L32DT30 were no fluke, and that the technology that makes such 3D standards possible is definitely more at home and appreciated on the L37DT30’s larger screen.

The lack of crosstalk is again startling, with no other LCD TV we’ve seen to date – aside from the L32DT30, of course – managing to suppress the ghosting problem so effectively. There’s not really any crosstalk at all during bright scenes, and although some dark scenes can show up a touch of ghosting around very bright objects, this is only true on a few very tricky scenes – like the lantern sequence in Tangled – which also happen to cause some degree of crosstalk on every 3D TV, even plasma ones.
