Samsung UN46F6400 Review (UN46F6400AF)

46 inch Active 3D 120Hz LED TV

by , Senior Editor

Samsung UN46F6400The UN46F6400 fits into the very competitive 46 inch size class. The F6400 is a mid level TV with a few top tier features. 3D playback and micro dimming set it apart from the F6300 series below it. The inclusion of these features make it a very viable option since the F6800 includes these features, but goes a little further with design changes and refresh rates. The LA6200 series from LG, the R550A from Sony, and the ET60 series from Panasonic are going to be the biggest sources of competition.

  • Voice recognition feature is limited in effectiveness

    Picture Quality Rating: 8.6

    The UN46F6400 implements a semi-matte screen instead of the clear coat screen seen on top tier models. These matte-type screens reflect a lot of in room light. The result is a toned down image that doesn't have the brilliance seen in top tier models. A sense of depth in images is also reduced somewhat. The bright edge LED lighting helps to balance out the downsides of the matte screen by providing more rich colors and a good deal of contrast. The easy to set 10pt white balance really helps get color balance to look just right. Color reproduction is natural and not over saturated. All of that said, from relatively close to front and center we felt the picture displayed was very good with lots of light flow-through to help with depth perception. The picture is remarkably similar to the ES6500 from last year.

    Black Levels and Contrast – Solid Performance

    From a front and center position, black levels on the UN46F6400 are fantastic. The black letter box bars on the Days of Thunder Blu-ray are a deep inky black. Other dark areas of the screen show just as strong performance without too much loss of detail. Blacks are not as stout as the best Plasma TVs, but for a mid level LED TV they are strong. Contrast has a great showing here too. Light and dark areas of the screen are separated nicely and don't bleed into each other – as long as you are not at side angles.

    Picture Modes

    Dynamic – Over saturated but not as much as some of the other brands. The backlight and contrast are maxed out. The sharpness is a little softer than most dynamic modes.
    Standard – This is the energy saving mode. Contrast is maxed out and the backlight is cut to about 50% at a setting of 12.
    Natural – Again, maxed out backlight and contrast here as well. It has more yellow tone. This is a very bright picture mode - A close cousin to the dynamic setting.
    Movie – The closest to a good calibrated picture setting. The contrast is bumped down a bit and the backlight isn't overpowered. The advanced settings are enabled. Warm2 color tone is the default.

    Side Viewing Angles – Typical for an LED TV

    The biggest problem with this TV's picture is the side angle viewing. Color and contrast degrade pretty early at about 20 degrees off center and get worse faster from there. The amount of “wash out” is also more severe than LED TVs with the previously mentions clear coat screen finish. Above and below off center viewing give a similar result. This is important for those who plan on wall mounting the TV above eye level and for those with wide angles in their viewing room.

    120Hz Processing

    The native 120Hz panel on the UN46F6400 used to reduce motion blur during fast action. Even though the screen is only 46 inches, this feature is going to make quite the difference. Those who are especially keen at noticing things like motion blur and judder are going to notice the improvement 120Hz has over 60Hz. The 120Hz upgrade is going to smooth fast action and side to side panning to create images with greater clarity. It's going to be noticed the most during sports programming that has a lot of camera movement. This also applies to shows and movies that utilize camera movement like side to side panning.

    This shot from the Days of Thunder Blu-ray is an excellent example of the sharp detail, strong contrast, and bright colors the 46F6400 LED TV is capable of from front and center

    Auto Motion Plus- Very Important Setting

    The Auto Motion Plus feature is set to On by default in all of the preset picture setting modes. It is really only good for watching 3D content on the UN46F6400 – unless you like the “Soap Opera Kitchy Cardboard Cutout” effect which results from eliminating too much natural background blur. For everything but 3D you are better off turning it off or going to the Custom setting within Auto Motion Plus and turning the Blur Reduction setting to 10 and the Judder reduction setting to 0. This is also an acceptable option. The feature creates a lot of background clarification, making images look terribly unrealistic by eliminating natural background blur and causing unnatural looking movement. Turn it off in the Picture Options menu and everything will be fine again. 480i definition content gained slight improvements when the setting was low.

    (Note: to get to the setting click on Menu, swipe across to Picture, Scroll all the way down to Picture Options, Scroll down to AutoMotion Plus.)

    3D Performance

    Before you continue to with your 3D content, Change the picture mode to Movie and the Auto Motion to Standard. This is key to getting the best out of any 3D image. In doing so, judder is eliminated and images bright. The resulting image is sharp and clear with a good amount of depth. Colors appeared slightly subdued for 3D images, but they are certainly not bad. As usual for active 3D glasses, a small amount of flicker is present. It may be better suited for dark viewing rooms. Just like the side angle viewing for 2D content, color and contrast fade very quickly when moving from front and center. Overall the UN46F6400 gives a good performance.

    Another plus when it comes to Samsung is their 3D glasses. The glasses are usually a sore point for the 3D experience. Active 3D glasses in the past have been heavy and uncomfortable to wear for an extended period of time. They also tend to cause a bit of eye strain for the wearer. Samsung's are different. They are light and comfortable. There tends to be a bit of flicker in the glasses is there is a direct light source in the front of the room where you are viewing.

    Gaming – Not Bad After some Tweaks

    Getting to the Game Mode
    Go to the Systems menu near the bottom of the main menu. Scroll down to the General settings and open that menu. Game Mode is located here. It seems like a pain to dig into the menus like this to turn it on or off.

    Turning on the Game Mode is the best way to go for gaming on the 46F6400. The picture mode in Game Mode has its own settings, and initially look pretty bad. Standard is the only available picture mode while Game Mode is on. Take the time to turn the sharpness down to 10 or less, the Color Space to Auto, Dynamic Contrast to Off, Color Tone to Warm1, and the Screen Size to Screen Fit. Adjust the Backlight and Brightness to your personal preference. This will provide a decent picture quality as well as a cut down on input lag. This made Okami HD and Crysis for the PS3 look fantastic and the input lag was negligible at a decent 30ms. Enabling 3D once again changes the picture mode. Make similar adjustments to get the picture looking better. 3D produced a lot of judder and may not be the best way to enjoy a game. We tried out 3D with Crysis. The effects of depth look great but have a bit of cross talk to take away from the immersion.

    Samsung Smart Hub 2.0

    The Smart Hub platform for 2013 has been majorly redesigned for the better. It seems a lot of effort has gone into making the platform more intuitive and user friendly. I'd say they've done it. Navigation and organization of content saw the biggest upgrades while features like voice-recognition and smart recommendation features are added to the mix. The UN46F6400 does not implement the quad-core processor like some of the top tier models. Instead it uses dual-core processing to run browsing and smart TV navigation. Last year the Smart Hub was run down with slowness and the occasional crash, but our tests didn't show any problems in that area.

    Read our full review of Samsung's 2013 Smart Hub here for more information on apps and voice recognition.

    On the Apps page you will find all of your downloaded apps, like the ones listed below. Samsung has also implemented lots of recommendation features this year. On the top of the screen you see some recommended apps

    Web Browser, Touch Pad Controller, and Wifi

    Bing is the default search engine and the home screen when the browser is first opened. Surfing with the touchpad is faster and easier than a traditional 5-way controller. Your thumb moves a cursor round as if it were on a laptop track pad. It's not as efficient as LG's Magic Remote, but we liked it. The voice recognition only works for inputting searches if the soft keyboard for the search field is open. The Wifi connection was easy to establish and it help up well while surfing the web. For streaming content it worked really great too.

    USB Playback

    The first thing you have to make sure of is to plug the device into the USB 2 Port marked with HDD. This port is designed to work with devices that have a lot of storage. When the menu to open the drive comes up select all media so it doesn't only show pictures or video. It didn't seem like there was an easy way to switch the content types. From there it's pretty simple to navigate the drive to find your content and get it to play on the TV. This is a great way to turn your TV into a giant photo frame.

    Dual Core Processor

    Many of the Smart TVs from the 2013/2014 Samsung lineup have received dual core processors. This is a very nice upgrade for TVs residing in the mid tier category like the UN46F6400. The dual core processor speeds up navigation and web browsing considerably. We recall the slowness of Smart TVs in the past and are very welcoming to this speed boost. The top tier models in the Samsung lineup this year have received quad core processors as an even further upgrade. Since the F6400 is looking to be a value TV, a dual core processor will surely do the trick.

    Touch-Pad Remote - Nifty


    Samsung Smart Touch Remote
    The remote for the UN46F6400 has a swipe pad that makes it easy to switch between the main Smart Hub screens. This one is black instead silver found on the top tier models.

    Swiping on the touch remote is definitely faster than a 5-way controller. We found it to be about 2x faster than pressing arrow buttons. It's the only remote included with the UN46F6400. Be aware that there are no numbers and not too many buttons. Samsung has included an on-screen soft remote to make up for insufficient keys. We didn't find ourselves missing some of the buttons, but having to access an on-screen menu to switch to channel 75 seems like it would be a chore. There are dedicated keys for the Mic, 3D, Smart TV, DVR, and the Menu. The remote also has a nifty back-light button.

    Sound Quality – Room for Improvement

    The speakers can push a plenty of volume at 50% to fill a room. However, voices are weak and overpowered by music or background noise. When viewing Days of Thunder we thought there was ample volume, but we struggled to hear voices throughout the movie. We tried Standard, Music, Movie, Clear Voice, and Amplify none of which improved the situation. Clear Voice or Standard is probably our preferred mode for this TV. Standard is probably the best all around, but it doesn't have the full range we have seen on some of the LG LED TVs. Turning on DTS TruSurround in the Sound Effects menu helps a little with the flatness, but doesn't do a lot for the range.

    Appearance

    The 4 legged quadrapod stand has a dark charcoal metallic color instead of the black from last year. The stand allows for about 25 degrees of swivel in either direction. The glossy black plastic bezels measures half an inch with a clear acrylic plastic on the outside to frame them up nicely. It's hard to notice the clear frame without looking for it. The overall depth is just under 2 inches. It's a simple but attractive design.

    Value Rating:8.8

    The Samsung UN46F6400 sells for $999.99. It is loaded with a strong feature set while side angle viewing is one of the biggest drawbacks. The LG 47LA6900 is the closest LED TV competitor to the F6400. It is slightly more expensive, but boasts an extra inch on the screen size and the eye pleasing look of LG's LED TVs. The Panasonic TC-P50ST60 is a bigger plasma TV that sells for the same price. The features aren't quite as strong, but the side angle viewing problem is eliminated with that option.

    Overall Rating: 8.8
