What is the Toshiba 40TL968?
Design & Connections
Overall dynamic range from the Toshiba 40TL968B was good, if not great, but somewhat marred by a panel that was troubled by uniformity problems. Our ANSI test revealed a Contrast Ratio of around 2,500:1 but as you can see from the black portions of the pattern, black level ranged from a good 0.08 to an excellent 0.032 cd/m2 due to the lighter patches around the screen.
The Toshiba TL968 did a decent job with standard definition content, cleanly scaling a 576 signal, with no obvious signs of softening or haloing artefacts. The 968 isn’t a good video deinterlacer, however, with jaggies appearing in the mid portions of our test patterns. Like most recent Toshiba’s, the 40TL968B was also unable to detect a 2:2 film cadence so there is some unnecessary deinterlacing introduced and with it some resolution loss. We’ve criticised some recent Toshiba TVs for their lack of proper 1080p24 support, which meant they weren’t displaying the majority of Blu-ray discs at their optimum but the TL968 is decent in that regard; we could see the odd skipped frame and a touch of undue judder, from time to time, most of the time things ticked over quite well.
Anyone even remotely concerned with enjoying responsive gaming on the TL968B will need to change to the Game Picture Mode else be faced with lag of around 135 milliseconds. The Game mode does the trick in cutting down on any unnecessary processing by reducing input latency to around 49 milliseconds, which isn’t too bad but laggier than some we’ve tested. Panel response isn’t particularly impressive and we did notice some ghosting from time to time but it’s likely most won’t find it an issue. 3D gaming is quite laggy, however, and we took measurements around the 140 milliseconds mark in that mode.

Toshiba 40TL968 Picture Quality 2D
The problems didn’t stop with the green cast, unfortunately, and the review sample provided suffered with a lot of light pooling, edge bleed and panel banding – the unholy trinity of LED technology. The upshot of those issues were that dark scenes were marred and muddied by the unwanted outpouring of light, obscuring detail; the black bars in material with non-native 16:9 aspect would glow and any panning shots would clearly show up bands of alternating luminance across the screen. We have to accept that LED TVs can be a lottery when it comes to uniformity so we’re more than willing to believe there are better TL968’s out there but this one really wasn’t good. Add those in to the greenish mix of the Hollywood mode and we were left with a bit of a televisual disappointment.

- 3D was very watchable
- MediaGuide EPG is nice
- Lots of screen uniformity issues
- Unworkable calibration controls...
- ...with poor out of box performance
- Not much in Toshiba Places
Toshiba 40TL968 TV Review
We’ve had issues with Toshiba’s calibration controls, in the past, but not quite to the extent we suffered with the TL968B. They are, quite simply, unusable in their present state and even a gentle massage with either the white balance controls or the Colour Master system led to on-screen carnage. The result of this meant we were left with the default Hollywood picture mode as the best alternative, which wasn’t too bad in terms of primary and secondary colours but anything in-between could be marred by a heavy green cast. That wasn’t the only problem either, and a triumvirate of screen uniformity issues – pooling, bleed and panel banding – only further unhinged the experience. At least the 3D prowess of the TL968 lets us end on a positive note, where it actually outdid that of the 2D in terms of looking natural. Très bizarre!
We’re certainly happy to believe the review sample provided is an unusually bad example of what a TL968 can do but, based on the evidence in front of us, it’s not a display we could recommend at this time.
