Color Temperature

The Toshiba 40G300U had some troubles maintaining a consistent color temperature. As you can see from the chart below, when the signal starts to get darker, the color temperature becomes noticeably warmer. It's hard to say what type of movie or TV scene would bring this out the most, but it's likely something where you'd see a long gradation of shadows. Don't be surprised if the shadows start to get a little reddish. More on how we test color temperature.

RGB Curves

The Toshiba 40G300U's RGB color curve performance highlighted the TV's tendencies towards less than perfect color transitions. Sure, the curves are smooth overall, but if you look closely, you can see dozens of little steps in the lines, indicating that the TV is actually skipping over a lot of the values, combining two or three different values into identical shades.

Fortunately, there aren't any huge anomalies in the performance. Instead, it's just lots of tiny, overlooked values. Overall, we like the shape of the curve. We've seen better, but we've seen far worse. More on how we test RGB curves.
