Summary

The Samsung LE40A786 is an interesting display, not only because it features the still-elusive LED backlighting system, but also because it features some strange issues which we very rarely encounter on HDTV displays.

Certainly, the high contrast ratio afforded by this type of display is a killer feature. Going back to conventional LCD was incredibly difficult after watching the Samsung LE40A786. The fact that Samsung have added their usual comprehensive array of picture configuration and calibration options only sweetens the deal. Sadly, the aforementioned combing issue will irk hardcore videophiles, and the alarmingly high level of input lag may be a deal-breaker for video gamers. We can only assume that both of these issues – which do not appear on Samsung’s conventional LCD displays – are necessary evils included to support the LED backlighting. Users who desperately want an LCD with such a high contrast ratio would do well to give the LE40A786 a good look over; but the rest of us might want to wait until Samsung has worked out some of the quirks with its LED-based displays.
