Performance
The picture was wonderfully bright and bold right out of the box. We went straight to the ‘User’ picture setting, mainly because the named settings had titles which hinted at likely inaccuracies: ‘Vivid’, ‘Hi-Bright’ and so on. On ‘Hi-Bright’, for example, whites were hugely crushed (near whites indistinguishable from full white). ‘Vivid’ was respectable, though, if you don’t want to go delving into the settings to change things. On ‘User’, the grey scale was very good.
Making adjustments to the picture was harder than usual because these adjustments invoke a grey panel overlaying the picture, so you can’t immediately see the effect. Most TVs sensibly return to the picture during these settings, overlaying only the control slider. But we would recommend going in there anyway and dragging down the ‘Sharpness’ control from its default of 60 (out of 100) all the way down to zero. That will get rid of a tendency towards edginess, and flattened colour in human faces.
The local LED lighting was remarkably effective. Our test patterns (full white circles on a full black background) showed good deep blacks, with very little haloing or light splash around the circles, nor any breakthrough elsewhere on the screen.
There was a tendency for greens to be painted a little more strongly than is entirely realistic in such movies as Miss Potter, and reds as well to a degree. Dragging the ‘Saturation’ control down to around 50 tamed that. Deinterlacing of Miss Potter’s unusual 1080i/50 video was quite well handled, being tripped up only by the very trickiest of scenes.
For that matter, 576i/50 video was also deinterlaced accurately, with the TV determining the film or video cadence with almost perfect accuracy. The importance of that is for the delivery of both free-to-air TV received by the TV, and free-to-air delivered from a PVR. This TV is going to manage that side of things very well indeed.
Unusually, there are no motion smoothing options here (an absence we do not lament), though it does advertise Active Motion & Resolution+ to minimise blurring in fast-moving scenes. Certainly this TV had very little latency in the picture. From our test disc, we’d estimate around 50 to 60 milliseconds. Gamers should do well.
