Logik L323CD11 - 3D Pictures



One last potentially important spec to run by you is the fact that the L323CD11’s screen is only a 1,366×768 ‘HD Ready’ affair, rather than the full HD set up we might have expected on a passive 3D TV.

Kicking off our tests with the L323CD11’s all-important 3D capabilities, they’re… OK, actually. Certainly they’re good enough to confirm what we’d already pretty much decided: that when it comes to delivering effective 3D on a budget, the passive approach seems to work better than the active one. The main reason for this is that there’s hardly any crosstalk with passive 3D pictures, and not having your eyes constantly attempting to resolve crosstalk’s double ghosting flaw immediately makes watching the L323CD11 in 3D mode a relatively relaxing experience.

It must be said that the L323CD11’s pictures aren’t free of crosstalk, by any means. It occasionally crops up in a subtle way during difficult 3D sequences, and it spirals out of control if your viewing position finds your head more than 12-15 degrees above or below the L323CD11’s screen. But provided you avoid the vertical angle problem, there’s no doubt that the L323CD11‘s crosstalk is far less common than it is on most active 3D TVs – especially budget ones.

The L323CD11 also suffers with no flickering in 3D mode due to its passive glasses not requiring any ‘shuttering’ to deliver their 3D effect. A fact which also means again that there’s less reason for your eyes to become fatigued.

However, the L323CD11’s cheapness also lays bare passive 3D’s flaws more than we’ve tended to see on, say, LG’s LW550 and LW650T passive 3D TVs. For instance, it’s surprisingly easy even on a screen as small as 32in to see the physical structure of the passive 3D filter in the shape of horizontal lines that are especially visible over small, bright objects, over bright contoured edges, or where curves start to flatten out.

This, together with a slightly softer overall look to HD 3D sources than you would see on the best active 3D TVs, means that the L323CD11’s 3D images have a somewhat rough look to them overall. Though we suspect this won’t bother likely purchasers too much given how cheaply they’ve been able to get their hands on a 3D experience for themselves, their family, and mostly likely a few mates too (given the inclusion of 10 pairs of glasses).

What certainly should bother everyone, though, is the L323CD11’s 2D performance. For with dark scenes, at least, this TV substandard.

The dark scenes problem is a familiar one with budget screens; parts of the picture that should look black instead looking distractingly grey thanks to the screen’s inability to control its single light source astutely enough to produce a true black colour. In fact, so far as we can tell the L323CD11 doesn’t even have a dynamic contrast system, whereby the TV continually assesses the contrast requirement of the images being shown and automatically adjust its light output accordingly.

From this, it’s no surprise at all to discover that Logik quotes a contrast ratio of just 1000:1 for the L323CD11 – a figure that looks almost derisory versus the many hundreds of thousands and even millions to one now optimistically thrown about by most other TVs.
