2D Image Quality
As you can see from the subpixels shown above, the BL702 has a PSA panel, a type of screen that's fairly common in mid-range TVs.
But it has slightly higher contrast than most PSA panels. We measured it at 3,000:1, with black at 0.07 cd/m². That's enough for blacks not to appear washed-out and grey when watching the TV in a dark room.
Unfortunately, to deepen the blacks Toshiba had to play with the gamma and make it less balanced. What this means for the image is that darker areas of the shot are less detailed than they should be.
The colours are good, but could be more accurate (Delta E = 4). Certain shades appear overly saturated. For example, Jack Sparrow's skin looks a bit too red here.

frame after displaying the succeeding frame. The shorter the response time, the more fluid moving images will appear.
In terms of response time, the Toshiba 46BL702 is just above average. At 10.5 milliseconds, it can handle slow movements very well, but shots that contain particularly fast movement (say, the licence plate on a moving car) show more ghosting. 10.5 ms is too slow to reasonably recommend this TV to gamers. The display lag is 55 ms on average, which means it's about five frames slower than a cathode ray tube TV.
Like all LCDs, this one suffers from narrow viewing angles. We measured them at 1.5/5, making for some of the tightest viewing angles around. This is a far cry from plasma.
All the 100 Hz mode does is refresh the backlighting, so if you're a fan of fluid images, you'll probably be disappointed with the lack of motion interpolation. Motion interpolation is a function that, when well done, can help reduce ghosting and choppy images.
With dark images, the 46BL702 leaks small amounts of light out of the top of the screen, a flaw that's mostly only visible in a dark room.
The Toshiba 46BL702 has a matte plastic, imitation-metal body. The illusion holds up from far away, but not when you're right up in front of it.
The 46BL702 doesn't take long to get acquainted with, simply because it doesn't have very many functions. It has a media player that plugs into one of the two USB ports, which, we should mention, is a bad media player. It reads very few file types—in fact, it only reads one: MP4.
The 46BL702 comes with a run-of-the-mill remote control with soft buttons. Fortunately, the buttons are rather large and have enough space between each other so that you don't have to look at the remote every time you change the channel.
The audio isn't any better than Toshiba's other models. The sound is completely saturated across the spectrum and the bass is non-existent. We found just over 7% harmonic distortion, which is far too high, considering that the average TV has about 2%. And then there's the volume, which goes up to only 75 dB. That's just too low for a TV.
As is no surprise, this review ends on a good note because the Edge LED backlighting reduces the amount of energy the TV consumes. On standby, it's perfect. Our wattmeter showed less than one watt. When on and running, it consumes just 68 W (at 46 inches diagonally, that makes 117 W/m²).
- Good contrast (3040:1)
- Good black level (0.07 cd/m²)
- Mediocre sound
- Image settings not amazing
- Media player doesn't support many file types
The Toshiba 46BL702 is a pretty good TV—for the price. It would be better without the gamma and colour issues.
