Not the best budget TV we’ve reviewed, but it gets the job done for a reasonable price.

Color Temperature

Even if you don't know what the graph below is trying to describe, chances are you can tell it isn't good. Basically, the Sharp LC-40D78UN's color temperature shifts as it displays darker colors. We measured the white level a bit on the cool side to begin with (about 7150K), but it corrects that imbalance and then some as you enter the mid tones and darker. The TV ends up strattling the "it looks warm" and "it looks cool" gap, where black is the former and white is the latter, and only the middle grays look right. More on how we test color temperature.

RGB Curves

The LC-40D78UN had pretty accurate RGB representation. As you can see in the graph below, the red, green, and blue channels are all represented by smooth, even curves that continue to slop up until the very edge of the graph. This means fine gradients will display without issue and brightly colored areas won't look flat. Overall, the LC-40D78UN put up a good performance here. More on how we test RGB curves.

We've converted the above graph into small gradient strips below, to show you what you can expect from your TV's red, green, and blue channels. Look for where the black starts to kick in and any vertical lines: vertical lines imply adjacent colors aren't flowing into each other smoothly, which results in lost details.
