Product Description

Size: 40-Inch

February 2011
Compromise on price but not on features. Samsungs affordable 550 LCD HDTV series delivers Full HD resolution, playback of files from USB drives or over your home network from DLNA Certified devices, a wealth of HDMI inputs, and plenty more, all wrapped up in Samsungs eye-catching "Touch of Color" design.

Samsung LN40D550
An affordable 40-inch LCD panel with full HD resolution, DLNA/USB media playback, and other solid features.

Crisp, Clear Picture Quality From a TV With a True Sense of Style

1080p Full HD With Four HDMI Inputs

The LN40D550 delivers Full HD 1080p resolution, for a superb level of detail and clarity in your picture. To connect your sources, four separate HDMI inputs are provided, for delivering a Full HD picture and audio over a single cable.

Touch of Color Design

Samsungs "Touch of Color" design features a hint of amber color naturally blended into Samsungs traditional piano black bezel frame, for eye-catching style even when your TV is turned off.

Samsung LN40D550 DLNA
The LN40D550 lets you stream content directly from DLNA Certified devices (PCs, network storage, etc.) over your home network.
Samsung LN40D550 Touch of Color
Samsungs "Touch of Color" design features a hint of amber color naturally blended into Samsungs traditional piano black bezel frame.
Exceeds ENERGY STAR Standards

The LN40D550 exceeds the strict energy efficiency guidelines set by the EPA and US Department of Energy by up to 30%. That means you get lower utility costs, and a smaller carbon footprint.

ConnectShare Movie

Connect a thumb drive or digital camera quickly and easily via the LN40D550's USB port. An intuitive, user-friendly interface allows access to videos, music, or pictures via the remote.

AllShare DLNA Networking

For even more entertainment options, the LN40D550 lets you connect to your home network and stream music, videos, and photos from other DLNA Certified devices (your computer, network storage drive, etc.).

Game Mode

The LN40D550 features a "game mode," which turns off much of the picture processing for a faster video response. This is ideal for fast-paced video sources like video game systems, and will help gamers get the performance they're after.

Audio Performance

SRS' TheaterSound, available in new Samsung HDTVs, is an all-in-one audio suite that directly addresses the three most common consumer TV audio complaints--inconsistent volume levels, unintelligible vocals, and poor, dimension-less sound. SRS helps ensure you get great audio from the LN40D550's two 10-watt speakers, and additional technologies like Dolby Digital Plus and support for multi-channel sound (MTS) add even more on the sonic side of things.

PC Connectivity

The LN40D550 also features a PC input, so you an use it as a computer monitor.

Size Name: 32-Inch Verified Purchase
I chose this model over other 32-inch LCDs because I'm a sucker for things like network streaming, a 5-band equalizer, picture-in-picture, and firmware updating. It also has a semi-documented headphone jack in the rear -- just turn off the speakers for it to work. Also, the power cable detaches, so you can replace that yourself.

One might dismiss this TV altogether since it doesn't have LED edge lighting, but that tech does not appear to be earning its price premium so far, considering a higher percentage of panel defects, and a black level so intense that detail often gets lost. 60Hz is also not a deal-breaker, since 120Hz tends to only show its strength with sports programming.

The picture quality is ultimately subjective, of course. But I found it well above average. Unfortunately, you can't completely disable Dynamic Contrast. The TV will tell you that it's off, but some enterprising Internet detectives at televisioninfo.com have determined that this is a ruse, which leads to some unavoidable light trailing and somewhat crushed blacks. DVDs look surprisingly good, and standard-definition signals look very solid but not outstanding.

Dynamic Contrast, Black Tone, Shadow Detail, Edge Enhancement and the noise filters should probably be turned off. Unfortunately, these features can create more problems than they solve; use them sparingly. Like Spider-Man once said, "With power comes responsibility."

I have a Roku box connected through HDMI, an Xbox 360 via component, and clear QAM cable TV through the RF antenna jack in the rear. These hookups are going straight into the TV inputs -- no receiver. I figure that this eliminates a testing variable or two. Picture quality and sound was great from all three sources.

Size Name: 37-Inch Verified Purchase
I bought this item a few days ago after doing a multitude of research on flat screen TV's. Frankly, I was ready to be done! Our focus was finding a TV with an external width no larger than 37 5/8". We were faced with a limited selection of 37" TV's or some barely close 40" TV's. The 40" TV's that we had to choose from were LED and cost roughly $1000 or more. Rather than being faced with a close fit of an expensive TV, we decided 37" would suffice. Then we were caught between buying a Samsung or a Sony and whether to get LED or LCD. In my opinion, the Sony brand commands a brand premium in price. Nice TV's though. I read a lot about LED v. LCD. The LCD is still energy efficient and is energy star qualified. After seeing the picture difference of the LCD and LED. My wife and I were both okay with LCD. Then I researched the difference of 60 hz versus 120 hz refresh rates. Okay, I understand the technical mumbo jumbo of this, but after comparing in a store the difference I couldn't tell. Maybe my eyes are not good enough anymore. We also bought the Samsung USB wireless adapter. I thought from all my reading that this TV had some Internet functionality i.e. Netflix etc. It DOES NOT. If you have a Wii or some other game platform that allows internet access - use it and save your money. The wireless adapter will work with some Samsung Blu-Ray players as well. The only thing the wireless adapter will do is connect with your pc network and play movies, music, and pictures from your pc. If this for you - great buy the wireless. Note: it has a network interface for wired applications on the back as well.

The nitty gritty of the TV. It works fantastic. Exceeded expectations on standard definition movies and TV broadcasts. No dark "halo" effects when the picture is dark.

Size Name: 32-Inch Verified Purchase
For the last year I've been looking for a TV to replace my 2009 Samsung 26" LCD. It had what some people call "smudging" or "smearing" where if two really dark images move near one another, the black area would leave a trail. It looks sort of like when you make a dark circle with a pencil and run your finger over it. It made night scenes in movies and games really distracting. I even saw it in people with black hair watching 720p Lost episodes.

From what I can tell so far, this set has none of it. I went through a Sony, a Toshiba, an LG, and another Samsung. All but the LG had this issue, and the LG had atrocious black levels due to it being a technically "better" IPS panel. I love my LG IPS monitors, but for TV it looks awful. So I stuck with Samsung's PVA panels, and boy am I glad I did.

I immediately turned off all the video processing options and turned the backlight down from 14 to 8. IMPECCABLE picture as far as I'm concerned. Looks incredible even at 1080i. It's no plasma, but hey, 32-inch plasmas don't exist, so I'm content with LCD.

I have no idea how the input lag is for video games since I play relatively slowly paced games. No fighters, competitive FPS, or other twitch reflex games in my library. I'd be a bit leery if that's super critical for you until more accurate tests are out there. It seems fine to me, but I'm not very sensitive to lag, so take it with a grain of salt.

Bottom line, great picture quality, great black levels (for an LCD), decent motion handling (it IS only 60Hz), lots of options to mess with, plenty of inputs, a sleek design. I would buy this TV again in a heartbeat, personally. As the first reviewer said, JUST what I was looking for.
