Although CNET did not review the Samsung UND6000 series, we did review the UND6400 series.

Comparing the two on Samsung's Web site, the main difference is that the UND6400 has 3D capability, and includes two pair of 3D glasses; the UND6300 does not.

One other difference on the Web site is the UND6400's contrast ratio spec of "5,000,000:1 Dynamic Contrast Ratio," compared with no specification at all for the UND6000. Though this might be an indication of better black-level performance on the UND6400, we can't say for sure. Check out Specs to Ignore … Read more

Although CNET did not review the Samsung UND6300 series, we did review the UND6400 series.

Comparing the two on Samsung's Web site, the main difference is that the UND6400 has 3D capability, and includes two pair of 3D glasses; the UND6300 does not.

The 6400 has a "Graphite" finish compared with "Stone Gray" on the 6300. The latter also has a thicker bezel around the screen.

Both include Samsung's Smart TV Internet suite, but according to Samsung's feature comparison, the less-expensive 6300 gets a Web browser, and the 6400 does not. Despite the … Read more

The TC-PS30 series is Panasonic's least expensive plasma TV for 2011 to feature 1080p resolution. The main features-related difference between it and the TC-PST30 series is that the S30 lacks the ability to display 3D TV.

We also expect there to be some differences between the picture quality of the two, because the ST30 uses Panasonic's so-called Infinite Black 2 panel, whereas the S30 does not. Because of this difference, we suspect that the S30 might have worse black-level performance than the ST30, but until we test both, we won't know for sure.

Both models have similar … Read more

LaunchBar is a popular and long-lived productivity-enhancing app that can literally change the way you use your Mac--and that change can come gradually, as you learn the app's many tricks and secrets, bit by bit. At its most basic, LaunchBar is a completely keyboard-based way to find and open anything on your Mac with a few quick keystrokes. But its functionality goes far beyond that, letting you use keystrokes to manipulate files, send e-mails, search Web sites, and control apps like iTunes.

LaunchBar has an almost invisible interface, and you invoke it with--of course--a keystroke, which by default is … Read more

OS X conveniently provides the option to compress files or folders directly in the Finder, creating archives of documents in a single ZIP file that can be moved to backup locations, e-mailed to people, or otherwise managed. This can be done by selecting some files and choosing Compress (or Archive in prior OS X versions) from the File menu or contextual menu.

Uncompressing the files is as simple as double-clicking them, which will expand the contents right next to the original archive. While this is useful, when handling these ZIP archives you might wish to see the files inside them … Read more

Selecting text, particularly entire paragraphs in Notes and other text-heavy apps can be tricky, if not somewhat difficult.

If you need to select an entire paragraph, the first intuition most iPhone and iPad users have is to double-tap a word and drag the text selection handles to cover the entire paragraph.

Though this is an effective method of getting all your text selected, there's an easier way.

Next time you have to select a paragraph to copy and paste somewhere else, try using two fingers and swiping across the paragraph you wish to copy. The text will be selected … Read more

In terms of features, the major difference between the two is that the UNC5000 lacks the Samsung Apps Internet TV platform.

A few of the two series' specifications are also different. The UNC6500 has a 120Hz refresh rate along with dejudder processing, while the UNC5000 does not. The UNC6500 also has a higher dynamic contrast ratio spec, 5,000,000:1 versus 3,000,000:1. While we don't put much stock in these numbers, they could indicate that the UNC6500 has slightly better … Read more

Comparing the two on Vizio's Web site, it seems the main difference is that the XVT3D4SV is 3D-compatible, meaning it can play 3D video programming when watched through optional active shutter glasses. Vizio sells the glasses, model VSG-102, in a two-pack for about $200.

The XVT3D4SV is Vizio's only series to use active 3D technology rather than the passive method used by the XVT3D650SV and forthcoming 2011 Vizio models like the XVT3D5 series. See CNET's 3D TV FAQ for more information.

Although CNET did not review the LG LE5400 series, we did review the LE5500 series.

Comparing the two on LG's Web site, the 5500 has a slightly higher contrast ratio, as well as a slightly lower response time, both implying somewhat better picture quality. In practice we doubt either specification difference will make a big difference in picture quality (more info).

The LE5400 also has a "silver gray" accent to complement its glossy black, and the LE5500 is accented with "evening purple." The LE5400 series also has a 32-inch model, whereas the LE5500 does not.… Read more
