Panasonic TC-L37X2 LCD HDTV Review
The TC-L37X2 is a flawed entry-level LCD from Panasonic.
The Panasonic TC-L37X2 did not impress us with its black level. As we've seen before, Panasonic is just not a leading LCD TV maker. They're strength is in plasma displays. You can see from the chart below how Sony and Samsung performed much better. More on how we test black level.
The peak brightness was pretty terrible, measuring only 167.34 cd/m2. Granted, you can get the peak brightness higher, but it comes at the cost of seriously compromised color performance (learn more). We consider color performance more important, and we're willing to take a hit on brightness. Or better yet, find a different TV. More on how we test peak brightness.
The Panasonic TC-L37X2 has a serious compromise. You can either leave the menu's contrast setting high, which helps the TV's contrast ratio but, again, kills color performance. Or you can lower contrast setting to rescue the color performance, but lose a lot of contrast ratio. There's always a little trade-off, but a TV should never make you choose between two such extremes.
Contrast Ratio with High Contrast Setting
Below is the contrast ratio with the contrast set to 90, rather than 68. It hurts contrast ratio quite a bit, but helps immensely with color performance. More on how we test contrast.
The Panasonic TC-L37X2 had no problems maintaining a consistent black level, regardless of how much or how little black was on the screen. More on how we test tunnel contrast.
The Panasonic TC-L37X2 also had no problems with maintaining a consistent peak brightness. More on how we test white falloff.
The Panasonic TC-L37X2 definitely showed some issues with screen uniformity. On an all-black screen, the corners and edges of the screen were much brighter, a typical problem on LCD displays. On an all-white screen, the corners and edges darkened. More on how we test white falloff.
The greyscale gamma looks at how well a TV transitions from black to white. The chart below tells you a lot about the performance. Ideally, we want a smooth line. The bumps that you see below are indications that the TV might be screwing up what should be a smooth, gradated transition. There's also the slope of the line to consider. An ideal slope is somewhere between 2.1 and 2.2. This Panasonic TC-L37X2's slope of 2.48 is a bit steeper, but not too bad compared to most TVs. More on how we test greyscale gamma.
