CNET did not review the Samsung UNC5000 series, but we did review a similar series, the UNC6500.
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 black-level performance than the UNC5000. Check out our TV Buying Guide for more information on these specs and features.
The two LED-based LCD TVs have different styling as well, with the UNC5000 sporting a red-tinted frame and measuring 0.1 inch thicker.
As far as we can tell there are no other major differences between the two series. For more information, check out our full review of the Samsung UNC6500 series.
