Test results
In the chart below, you'll find the test results from our most popular HDTVs, sorted by screen size. Our researchers test new TVs as they become available and report the results in the "Features & Specs" tab on TV pages at Crutchfield.com.
As you look over the results, you'll notice that LCD TVs tend to be more energy efficient than plasma models of the same size, though there were a few plasma models that were surprisingly thrifty.
We hope you find this information useful. Please email comments and suggestions to environment@crutchfield.com.
