The Toshiba L3400U LED TV is a smart TV, but it is the most limited that we have seen. The picture quality is great for the price, with the exception of a significant amount of motion blur.

  • Excellent contrast ratio
  • Few reflections, so you can also use it in a relatively bright room.
  • Colors out of the box were off. Calibration fixed most of the issues.
  • Significant amount of motion blur. This TV isn't good for sports or video games (although the input lag was very low).
  • Very limited smart TV features. The TV practically only has YouTube and Netflix on it, and no web browser.

Toshiba L3400U Design

As expected, considering the price, the Toshiba L3400U feels a bit cheap. At least the borders are small and the TV is thin.

Toshiba L3400U Stand

The stand is very sturdy, and it can fit even on a small table.

Black : 0.019 cd/m2
White : 100.1 cd/m2
Contrast : 5268 : 1

The contrast ratio is surprisingly good for a TV in this price range. That said, the color calibration out of the box was way off.

8.0 Black Uniformity
Toshiba L3400U Black Uniformity

The black uniformity wasn't perfect, but it is not so bad. Two brighter spots can be seen, one at the bottom right and one on the left edge.

4.0 Gray Uniformity
Toshiba L3400U Gray Uniformity

The Toshiba L3400U doesn't have good gray uniformity. The edges are noticeably darker than the center of the screen.

6.4 Viewing Angle
Viewing Angle : 24 °

The tint of the colors changes when viewed at an angle. The contrast is also greatly reduced.

9.0 Average Room
Toshiba L3400U Average Room
Reflection : 1.7 %
Surface Type : Semi-gloss

The L3400U LED TV doesn't reflect a lot of light, so you won't have any problem watching it with a few lights on at night.

7.5 Bright Room

Max white : 244.2 cd/m2

It doesn't get very bright, though. It is still enough for 1-2 windows during the day, but not for a very bright room.

5.0 Motion Blur

Like the cheaper Toshiba L1400U, the L3400U also has a motion blur problem. It is fine for normal TV shows, but not for sports or video games.

Toshiba L3400U Smart TV

The smart TV features are the most limited that we have seen so far, with only Netflix, YouTube and media share (for USB playback) available. No web browser or app store is available.

The smart TV interface is pretty useless, so unless you only plan on using Netflix, get the cheaper Toshiba L1400U instead. The picture quality is very similar, although the uniformity is a bit better on the Toshiba L3400U.
