Late last year, we published a warning for Black Friday TV buyers: The main reason was the visual quality, as edge-lit panels aren't great for big sizes. But a new report suggests another reason you should steer clear. Big edge-lit panels appear to fail more quickly than other types of TV displays.
That's according to Rtings' ongoing TV longevity tests, as reported by . The tests feature 100 different TVs from multiple brands and with multiple technologies – edge-LED, direct LED, full array local dimming, and – and the results for edge-LED aren't great.

According to Rtings, over 25% of the LCD TVs they tested exhibited visible light uniformity issues. But among edge-LED LCD TVs, that figure rocketed to 64% – so you've got a one in three chance of getting a TV with consistent lighting. To be fair, the number of sets affected is small: seven out of 100 TVs.
However, three of those seven started showing problems before or after 2,200 hours of testing. That's the equivalent of one year's viewing in the typical US household. According to Rtings, the results of their tests demonstrate that " That's the bad news.
But the good news is that with Black Friday nearly here, you won't necessarily have to plump for edge-lit if you want a nice big TV that fits your budget: this is, of course, one of the best times to buy a new TV because they're a big part of every Black Friday, and even high-spec models such as .
