Black Level

The Toshiba 32SL400U produced a solid score in our black level test. As you can see in the chart below, the Toshiba managed slightly deeper blacks than the similar Sony and Samsung TVs. However, if you scroll down towards the bottom of the page, you'll see our Greyscale Gamma test, which indicates that the TV has a hard time actually producing detail in those shadows, even if they are impressively dark. More on how we test black level.

Peak Brightness

The Toshiba 32SL400U did not do so well producing a bright white. A glance at the chart below shows that it trails the competition by quite a bit. More on how we test peak brightness.

Contrast

The Toshiba 32SL400U did not produce an outstanding contrast ratio, primarily because the peak brightness score was not very good. More on how we test contrast.

Tunnel Contrast

The Toshiba 32SL400U does not have too much trouble maintaining a consistent black level. Frequently, if a small patch of black area is surrounded by bright white, that black will not be as deep as a large black patch. We did not see an issue with this TV. More on how we test tunnel contrast.

White Falloff

The Toshiba 32SL400U has no trouble maintaining a consistent peak brightness. More on how we test white falloff.

Uniformity

The Toshiba 32SL400U does a poor job of creating a uniform luminance across the screen. On a dark screen, you can see heavy flashlighting in the corners. There was also some general blotchiness across the screen. You will almost definitely see these problems if you're watching a movie with a lot of darkness. On a brighter screen, it was harder to see the problems. More on how we test white falloff.

Greyscale Gamma

The greyscale gamma test indicates how well a TV transitions from black to white along the greyscale. We can learn a lot by looking at the chart below. The first thing we're looking for is a smooth line. As you can see, the line is far from smooth. The area in the lower left, representing the shadow details, is nearly flat. This means the TV has a hard time displaying meaningful details in the shadows. Moving right, it then hits its stride and moves steadily upward in a relatively smooth line.The other factor we're looking at is the slope of the curve. An ideal curve is between 2.1 and 2.2. The Toshiba 32SL400U's performance of a 2.66 slope is a little steep, so you can expect it to miss some of the finer gradations. More on how we test greyscale gamma.
