Design and Connections
Assembling the stand was simple enough, once you had worked out which screws went where, but there was the same sense of inferior construction found on the main chassis. Overall the TV lacked the well-engineered feel found with the bigger brands, resulting in an uninspired design, coupled with a healthy dose of plagiarism, and all constructed for the minimum cost. On the positive side of things, the Bush at least swivels on its stand and the hardwired power cable is a reasonable 2m in length.
The are at least a reasonable set of connections at the rear, with 3 HDMI inputs, a VGA input, two USB ports (one for the supplied WiFi dongle) and a LAN socket. There are also inputs for legacy connectors such as Scart, component and composite with the necessary break-out cables provided. Finally there is a CI (Common Interface) slot, an aerial socket, a headphone jack and some audio connections including a SPDIF digital out. Our only complaint in this area is that the sideways facing HDMI inputs are only 11cm from the edge, which is too close in our opinion.
Finally there is the Picture menu where we would expect to find the usual selection of picture controls, so imagine our surprise when all we discovered were Picture Mode, Colour Temperature, Aspect Ratio, Noise Reduction and Advanced Settings. Where were the usual Brightness, Contrast, Colour and Sharpness controls? Well as it turned out, they resided in theAdvanced Settings menu, which is the first time we've ever seen these controls listed as advanced features. Also in the so-called Advanced Settings, was a Tint control and controls for adjusting Red, Green and Blue.
Audio and Features
The Bush also includes some basic media playback capabilities and if you attach a USB drive you can watch videos, look at pictures and listen to music. The file compatibility is fairly basic but it includes the usual AVI, MP3 and JPEG support. Along with the media player, there is the ability to hook up a USB storage device to enable the use of PVR (Personal Video Recorder) facilities; meaning pause, rewind and record capabilities from the inbuilt tuner. The Bush is also DLNA compliant, so you can connect it to your home network (wired or wireless) but the file support is equally as limited.
The Bush has no real calibration controls and we were unable to improve the colour accuracy using either the Colour or Tint controls. It was possible to improve the accuracy of white using the red, green and blue controls but only at the expense of greater inaccuracy in the primary colours and especially the secondary colours. Ultimately the best performance we could get is shown in the graphs above and frankly this is a rather poor showing for a modern TV.
The Bush performed rather poorly in the video processing tests, with the scaling resulting in some softness to standard definition content. The video deinterlacing was also sub-par with jaggies appearing when the line wasn't at an acute angle in the first test and jaggies appearing on all three moving bars in the second. The TV even failed to correctly detect PAL 2:2 cadence which will result in a loss of resolution with film based content. The Bush had problems showing details up to video level 255 with white obviously clipping and this extended to the primary colours as well, resulting in a loss of detail in the bright parts of the image. At least the Bush was able to display down to video level 16 properly, which means it was maintaining the shadow detail. Motion handling was also a disappointment, even for a LCD TV, and the wedge patterns on the Spears & Munsil test disc confirmed our suspicions that there was some undefeatable frame interpolation going on. Sadly things didn't improve with 24p content, which whilst free of frame interpolation, was subject to some judder.
The Bush has no dedicated Game mode, so we measured the input lag for all the different available modes and the lowest was the User mode at 65ms. This is clearly too high for a dedicated gamer and even the more casual proponents will notice a lag this high, so the Bush is not really suited for use as a gaming display.

Bush (C46Z18DVBIPTVT2) 46 Inch LED LCD Smart TV Review
The picture controls are basic in the extreme, with even standard controls such as Brightness and Contrast being considered 'advanced'. As a result the picture accuracy was poor even after careful setup and with no real calibration controls, there was little we could do to improve matters. The video processing was also a major let down and the motion handling was equally as poor, with undefeatable frame interpolation apparent. Whilst the contrast performance and dynamic range were average for a LCD, this was made worse by a Gamma curve that was too low and an uneven backlight. The whites and primary colours were also clipped, resulting in a loss of detail in the bright parts of the image.
As a result of all these limitations the picture quality left a lot to be desired, with jaggies and other artefacts obvious on standard definition content; the built-in tuner was particularly poor with a very processed look. Things improved with DVDs, especially if the Bush's internal video processing was by-passed but the image inaccuracies and undefeatable frame interpolation still affected the performance. In fact, motion handling was always a problem and even 24p content didn't escape judder. The smart TV features are minimal compared to the competition these days and with an input lag of 65ms and no Game mode, the Bush would be a poor choice for a serious gamer. On the plus side, the audio performance was actually rather good and the TV is energy efficient.
The Bush 46" LED LCD TV is a major disappointment in almost every area and the simple fact is that there's better performance available at similar prices from many other manufacturers .
