Samsung Un55d8000 Review

Samsung's 2011 D8000 LED LCD is their prime of the road series, providing the most options and highest performance of any of their 2011 LCD models. The 55-in., 240 Hz refresh rate style provides glorious screen brightness with outstanding energy potency.  New for 2011 is an LED dimming circuit Samsung calls “micro dimming” for deep blacks, a QWERTY remote management, engineered-in Internet browser, updated graphic user interface and improved 2D and 3D performance claims.

 

Initial Impressions

Samsung created a number of internal and external changes from last year's UN55C8000. We tend to liked a range of the new attributes: 3D performance, signal processing, and the good selection of user image controls. However, we have a tendency to noticed two performance issues: screen uniformity and poor vertical viewing angle, detailed below. 

HDTVs On Sale

Styling

Cosmetically, Samsung trimmed the frame around the active picture space to an astonishing 0.94-inches, giving this HDTV an virtually all-image look once powered-up. It is one of the simplest-trying TV designs of all time. The display sits on a four-legged, chrome-finished swivel stand (included). Samsung cleaned up the rear by creating all connections built-in, sans part and composite AV inputs that, like last year, still require included dongles. With a panel depth of simply 1.2 inches the 8000 is one in every of the slimmest sets accessible.

Connectivity

All the UN55D8000's inputs are located on the rear of the TV. They embody four HDMI inputs, one each element and composite input (as mention, these require the provided dongle), 3 USB ports, 1 D-sub fifteen LAPTOP input, F-kind antenna input and an Ethernet jack (there's also engineered-in Wi-Fi).

Remote

The new-for-2011 remote control is an asymmetrical, wedge-shaped twin-sided affair. The A-side has the standard TV controls with a numeric keyboard, and the usual source, menu, volume, channel +/-, tools, etc. buttons. There's a backlight for this facet. New for 2011 is an “E-manual” button for an electronic user manual.

Now, we have a tendency to haven't any drawback with a designed-in electronic copy of the user manual. However, Samsung has foolishly followed Sony's 2010 lead and set not to incorporate a whole printed user manual. In its place is a terribly sparse 23-page pamphlet that covers heady topics like remote battery insertion and connections. In our opinion, the exclusion of a real manual is inexcusable for a $3600 (retail) TV. Internet connected HDTVs have many controls and we hate the thought of needing to find an rationalization of functions by entering the E-manual, then exiting, attempting the perform and then reentering the E-manual for more data. Sort of reminds us of shampoo directions (shampoo, rinse, repeat) and isn't idea for the operation of a TV.

To their credit, Samsung client service says they can send a bound. printed. full 325-page owner's manual if you call 1-800-Samsung and create a call for participation.

Back to the remote. Flipping it over over reveals a QWERTY keyboard. Most notably, it needs “pairing” to sync to the TV. Samsung's supplied instruction pamphlet neglected to incorporate the words, “the remote must be inside eight inches of the TV to combine with the 8000,” a truth we have a tendency to learned solely once failing to get the darn thing to figure and making a call to Samsung's customer service (that happens to be located in the USA). The representative was terribly well trained and useful.

Once we got the remote “paired” we had a big downside with the keyboard for entry into the Internet browser. Entering hdguru.com would show up as hddguuruu.com requiring multiple backspaces and reentries. We tend to requested a replacement remote to work out if the double key entry is restricted to our sample and we'll update when we attempt another unit.

We tend to have other complaints regarding the QWERTY side. There's no backlight and several of the operate keys are therefore little we couldn't browse them without turning up the area lights. Overall we have a tendency to feel the remote wants to be larger for easier operation and requires larger keys. A nice concept but a poor execution.

Features

The list is sort of impressive. It includes Internet streaming (VUDU, Netflix and Blockbuster) and other applications using an open platform. This means new services and apps will be added via a software update. Alternative capabilities embrace 3D with new Bluetooth RF-sync glasses , Skype video (with optional camera), a big selection of custom picture controls, fine management of its 240Hz processing, and multiple choices for enabling sectional image dimming.

There are four image modes, and varied additional settings including de-judder, color temperature, grey scale (two or ten point), gamma, color management, noise reduction and others.

There also are changes for gray scale, color points and gamma, although all require precise test equipment to line properly. We have a tendency to suggest hiring a qualified ISF calibrator with high quality take a look at gear (those cheapo do-it-yourself kits don't cut it) or merely leave the grey scale controls at factory default in the Warm two setting (they were very accurate with our review sample, measurements are listed below).

The motion estimation/motion compensation (ME/MC) circuits perform 2 functions, reducing motion blur and smoothing native 24Hz-based content. With 24 Hz-based content found on Blu-ray discs and a variety of scripted TV shows, you'll engage the anti-judder circuit while not activating the anti-blur circuit. The result will be smooth motion because the TV repeats the identical frame 10 times, eliminating uneven/jerky pans referred to as “judder”. With the anti-blur circuit in the “off” position motion resolution drops to 330 lines (per image height). Engaging anti-blur can increase the motion resolution to 1080 lines PPH while at the same time inserting synthesized frames that offer a video a look usually called the “Soap Opera Impact” or SOE. Many viewers notice SOE objectionable (though some people adore it). It's your choice, though personally we don't like the SOE therefore we have a tendency to kept the anti-blur management set to “off”.

There are a host of controls geared to manufacturing deeper blacks by reducing the light output of the LEDs, or in some cases shutting them off, and another management that simultaneously increase the white level. All these controls facilitate the image achieve the next distinction ratio, however it comes at the expense of burying black and lightweight details. They are labeled, Dynamic Distinction, Shadow Detail, Motion Lighting, Cinema Black, Black Tone, Smart LED and HDMI Black Level. We made our image evaluations with set to the “off” position except HDMI Black level that we set to “Low” (update: the 8000 automatically sets this management with video sources like a Blu-ray player, regardless of what the menu reads, in step with Samsung TV labs, we have a tendency to corrected the the text to reflect the actual setting)

Operation

The “Movie” picture mode comes closest to the perfect settings for the UN55D8000, thus we stuck with it throughout our testing except to measure most image brightness, where we used the Showroom mode labeled “Dynamic.”.  The 8000 passes the Energy Star four.0 certification, that requires the “Standard” mode because the default “Home” setting. The entire Energy Star program is befuddling and in our opinion arbitrary, with upcoming components soon to own profound a profound impact on image quality and client choice as it pertains to TVs. We tend to set up to cover the issues in a future article.

Back to our measurements, the 8000 read blazing eighty seven.thirty four ft. lamberts within the “Vivid” mode and a bright 41.seventeen ft lamberts using our calibrated “Movie” mode settings. LED LCDs are the most energy economical TVs out there and this Samsung was no exception, using simply 86 watts with the IEC check disc (again within the “Movie” setting). Be aware the UN55D8000 is one in all the foremost expensive TVs available nowadays, currently selling for $269nine.sixty six on Amazon, due in part to the cost of the LED edge lighting. Therefore if you're expecting a return on your investment because it's energy economical, you may be in for a long wait.

The long list of image controls created tweaking the settings a time consuming affair.

Customary Defintion Tests

Like last year's C series 8000 model, the UN55D8000's signal processing does an excellent job upconverting customary definition 480i signals to 1080p, acing all the HQV SD tests including detail, jaggies, waving flag jaggies, 3:two pulldown detection and multi-rate film cadence. Only the mixed video titles with needed a switch over to Film Mode “Auto two? position, whereas other film mode tests need “Auto 1? to pass. We have a tendency to find this a minor bug and advocate sticking with Auto 1 for standard definition content.

There have been a few minor issues value noting. With 480i content you must have the image expanded, taking off regarding a pair of.five% of the image (with HD content you'll interact the “Screen Fit” mode with 1:1 facet ratio).

The user menus for the Noise Reduction modes perpetually cowl regarding 75percent of the image, creating the determination of that setting to use very troublesome. We tend to would love to work out Samsung offer these changes the little setting bar at the bottom as it does with the opposite adjustments.

High Defintion Tests

Checking the HQV Blu-ray check disc, the UN55D8000 passed all the tests (noise reduction, deinterlacing, jaggies and film resolution loss) though we have a tendency to once more had to move the control to the Film Mode Auto 2 to eliminate some noise in the last take a look at. We tend to never saw noise in any observations of real content, returning the control to position “1? for all our content viewing evaluations.

Color was shut to the Rec. 709 commonplace (noted in parenthesis) measuring:

Red x0.647 y0.333 (x0.sixty four, y0.thirty three)

Green x0.296 y0.602 (x0.30, y0.sixty)

Blue x0.151 y0.054 (x0.15, y0.06)

Black level is dependent on setting of the dynamic black circuits. Activated they can shut off the LED edge lighting providing a completely black image. If set to the “off” position the minimum black level measured 0.015 ft. lamberts, not terrible however not nearly as deep as we have a tendency to've measured with plasma technology such as the recently tested Panasonic TC-P50ST30, which came in at 0.008 ft. lamberts and sells for but [*fr1] the value. The 55-in. version of the ST30 continues to be about $1,000 less.

Grey scale within the Warm2 mode was thus close to ideal we have a tendency to doubt if anyone would see a visual profit to a full grey scale calibration (assuming alternative samples are as correct). The 8000 measured 6521K at twenty IRE (x0.312, y0.330) and 6521K at eighty IRE (x0.312, y0.330)

Prior to our review, reports appeared on the Internet indicating the part video input would not settle for signals on top of 480i. We tend to tested part video inputs with our Sencore 403 signal generator and Panasonic BDT-350 Blu-ray player and located the grievance erroneous. The 8000 accepts 480p, 720p, 1080i and 1080p/sixty signals via element video cable, although we tend to advocate connections via HDMI for the most effective signal quality (analog cables exhibit the loss of high frequencies seen as fine detail as cable length increases). HDMI cables don't.

3D

Samsung made 3D performance improvements over its 2010 LCD models. The result's an enormous reduction, however not  complete elimination of, crosstalk (seen as ghost images). We tend to observed crosstalk only on our toughest 3D tests that include the church exterior near the beginning of Monsters vs. Aliens and African Safari on DirecTV N3D. The TV and glasses now use radio signals to sync up. This allowed the active shutter glasses to work continuously regardless if we have a tendency to faced the TV. We have a tendency to sampled the new customary (regular battery) and deluxe (rechargeable) 3D Samsung glasses and found both lighter and way a lot of snug than last year's models. We tend to never observed any image flickering throughout our tests.

Overall Performance

With bright, well-lit scenes found in most scripted TV series, the UN55D8000 produced outstanding high definition images with vivid colours, high contrast and (with the Auto Motion Plus ME/MC 240 Hz circuit engaged) no visible motion blur. However there were 2 problems we have a tendency to encountered that knocks down our overall rating of this display. They are vertical dispersion and screen uniformity.

There's a terribly noticeable drop of in image contrast, seen as a drop in brightness and rise in black level, whenever we stood up from our 9-foot viewing distance. This is often a priority for anyone desperate to mount these TV at anything different than eye level.

The opposite drawback is the lack of screen uniformity, that was quite disturbing in dark scenes.  On top of are examples of this using frames from Minority Report and the splash screen of our 2010 Panasonic BDT-350 Blu-ray player. Another example, Chapter 8 at 26:23 in  I Am Legend with Can Smith walking around inside the abandoned building. The shortage of uniformity reveals itself in three ways: five dark vertical strips (see Panasonic splash screen higher than), a lightening of the correct and left edges (slightly additional prominent on the left) and at times some faint horizontal brighter stripes we believe are the light wave guides.

When testing this issue with our signal generator employing a full raster pattern, the unevenness can be seen with signal up to 75 IRE (out of one hundred maximum), though they're most noticeable below fifty IRE. Critical viewers could notice this issue to be a significant annoyance with choose movie content, whereas people that are not as picky may not care.

Final Thoughts

The Samsung UN55D8000 contains a heap going for it, Internet applications, skinny bezels, excellent signal processing, correct color, and good 3D performance. However we notice the poor uniformity a deal breaker for readers seeking the best quality HDTV. Taken as an entire we award the Samsung UN55D8000 ??? (3 out of five) rating.
