Samsung has done a great job making the LN46B750 easily usable. The inputs are all well placed, so you don't have to be a contortionist to plug in a new Blu-ray player or DVR. The wizard that helps you set up the TV the first time you turn it on asks all the right questions, such as whether you'll be using this TV at home or in a store (this makes it easier to optimize the settings for best quality depending on the TV's location). The attractive, readable, and intuitive main menu also helps make this a straightforward TV to handle--and if that main menu is too much for you, just press the remote's Tools button for a shorter selection of commonly changed options. The often annoying job of changing inputs (from the cable connection to the DVD player to an old VCR, for instance) is made simple by an on-screen menu that places the inputs you actually use at the beginning of its list of all the TV's inputs.

That's not to say that the user interface is free of issues. Although the LN46B750's main menu offers explanations of its various options, those explanations aren't always helpful. The Energy Saving option, for instance, is described merely as 'Turns the Energy Saving function off.' (You have to go to the manual to discover that this feature lowers the brightness of the backlight across all inputs.)

Though the menus may have the occasional flaw, I'd be hard-pressed to find any at all in the remote control. It's large, and it makes its easy-to-find-and-push buttons even easier to use with a backlight that comes on in the dark. In addition to the above-mentioned Tools button, it has convenient buttons for Internet access and the media player.

The remote does lack a picture-in-picture button, though, despite the fact that the LN46B750 has picture-in-picture. To access PIP you need to use the main menu or the tool menu. PIP works only for viewing the tuner's content and one external source, and you must be viewing the external source in order to turn PIP on.

According to the PC World Labs, this Energy Star 3.0-compliant HDTV consumes about 120 watts when in use, and less than a tenth of a watt (the lowest amount our equipment registers) when off.
