We'd like to see a real onscreen manual as opposed to the simplistic "connection guide." The troubleshooting section is nice, but is mostly geared toward easing the job of customer service reps tasked with diagnosing owner problems over the phone. We like the option to turn off the screen manually, leaving just the sound, which cuts power use down to 26 watts.

The jack pack is normal, aside from the fact that using the back composite video takes up one of the component video slots, and that the analog audio output is a single minijack as opposed to the standard red and white RCA jacks.
Although its picture quality surpassed that of the like-priced LG PK750, the Samsung C590 series fell short of the Panasonic G20/25 series, as well as the Samsung plasmas we reviewed last year, in a couple of areas: its black levels were only average and its color tended slightly but visibly toward blue. Like all plasmas, it trounces the uniformity and off-angle performance of just about every LCD, and while its screen reduces in-room reflections better than other Samsung plasmas we've tested, it doesn't maintain contrast as well under bright lights. Finally, after a firmware update, the C590 did properly handle 1080p/24 content.
As usual for Samsung the Movie preset delivered the most accurate picture out of the box. It showed a solid 2.27 gamma (the target is 2.2) but a relatively uneven, bluish grayscale, especially at the lower end. For our calibration we were able to tweak matters for the better, hitting a 2.21 gamma at our target 40ftl light output, but we couldn't do as much as we'd like to improve the grayscale. It's also notable that the C590 is missing a color management system, since this is the first Samsung TV we've tested in awhile that evinced less accurate primary colors (namely green).
Our image quality tests entailed checking out "Righteous Kill" on Blu-ray and comparing the Samsung PNC590 series to the lineup below.
|Comparison models (details)|
|LG 50PK750||50-inch plasma|
|Panasonic TC-P50G20||50-inch plasma|
|Samsung PN50B650||50-inch plasma|
|LG 47LE8500||47-inch full array local dimming LED|
|55-inch edge-lit local dimming LED|
|Pioneer PRO-111FD (reference)||50-inch plasma|
Black level: While its black levels were decent, especially compared to many LCDs and a few plasmas we've tested, Samsung C590 delivered a lighter shade of black than any of the other displays in our lineup aside from the LG PK750. The difference was immediately apparent in the black background of the credits and the letterbox bars, as well as in darker scenes like the nighttime chess match and the shooting gallery in Chapter 1, and the dark background behind Pacino's face outside the crime scene in Chapter 2. The difference between the C590 and the other two Samsungs was relatively subtle yet visible in side-by-side comparisons, and became more obvious on the Panasonic, Pioneer and LG 8500.
Shadow detail also turned out relatively well, although near-black areas like Pacino's leather jacket and DeNiro's black suit in the shadowy living room in Chapter 1, or their faces in the dark church in Chapter 2, appeared just a bit more-obscured than on some of the better displays in the lineup, and about the same as we saw on the B650. On the other hand these areas looked somewhat more natural than the lighter shadows we saw on the Panasonic.
Color accuracy: As we mentioned above, the grayscale on the C590 tended toward blue in midbright areas, which manifested most in somewhat paler skin tones, like the face of Karen Corelli as she enters the apartment in Chapter 3 and her legs thereafter, as well as in slightly bluish-white areas, like DeNiro's black-and-white confessional scenes. Skin tones did lack that slight greenish/yellowish tint of the Panasonic, but its warmer look still came closer to our reference than did the Samsung. Saturation on the C590 was robust, thanks to solid color decoding, albeit not quite as strong as some of the other sets in our lineup.
While most of the primary and secondary colors measured close to the reference on the C590, green was the exception. That said, we didn't notice a major difference in green areas, like the trees and grass of the ball field in Chapter 6, compared to our reference.
Like the LG PK750, the C590 also tended toward blue in darker areas, so black and near-black shadows evinced a slight bluish tint absent from the Panasonic and Pioneer, for example. It wasn't nearly as bad as we saw on the Samsung C8000 LCD, however.
Video processing: (Updated September 29, 2010) When we first reviewed the PNC590 in May, the Cinema Smooth option, which is designed to enable proper reproduction of 1080p/24 content, didn't function correctly. When watching our favorite test for proper 1080p/24 cadence, the flyover of the deck of the Intrepid from "I Am Legend," we reported seeing "an unusual jerking of the entire frame about every half-second."
Samsung at first attempted to send us updated firmware but for some reason our original review sample couldn't be updated. Now, after testing an entirely new review sample (which displays firmware version "2010/07/09_001014"), we can report that 1080p/24 processing in Cinema Smooth works properly. Our test showed the proper cadence of film with no skipping and no evidence of the more-subtle hitching motion of 2:3 pulldown. Samsung assures us that PNC590 owners who update their firmware using the TV's internal, online system--in the menu, choose Support>Software Upgrade>By Online with LAN connected--will have access to the updated firmware and thus 1080p/24 capability.
"600Hz Subfields" is listed as a selling point on Samsung's Web site, which sounds like the "600Hz Sub-field Drive" touted by Panasonic, but the two didn't deliver the same results. The Samsung C590 didn't quite match the motion resolution of the Panasonic, the Pioneer, or the 240Hz LCDs in our comparisons, delivering between 800 and 900 lines, according to our test. However, that's still very good and as usual, we suspect that even the most blur-sensitive viewers won't notice a difference with regular program material.
Bright lighting: In our brightly lit room, the Samsung PNC590 series performed well--about on par with the Panasonic--reducing reflections better than either of the other Samsungs (including the B650 plasma, which obviously has a much different antireflective screen) but not preserving black levels nearly as well. It beat both of the LGs in these areas, but fell short of the Pioneer.
Standard-definition: The Samsung PNC590 didn't handle standard-def sources as well as the other Samsungs we tested, although it still outdid the Panasonic. It delivered every line of the DVD format, although details in the grass and stone bridge did appear a bit soft. Its biggest failure, however, took the form of significant jaggies in moving diagonal lines and a waving American flag. Noise reduction was solid, however, and even the company's Auto setting kicked in well to remove most of the noise from lower-quality sources. The set also correctly implemented 2:3 pull-down detection.
PC: Via both analog and HDMI, the Samsung plasma performed as well as we expect of any 1080p display. It perfectly resolved every line of a 1,020x1,080 source with no overscan or edge enhancement, and text looked sharp.
