Full Review – Samsung UE48JU6400
Out of the box the Samsung UE48JU6400 provides a high quality picture. The 48 inch screen is large enough that you can really appreciate the extra 4K resolution over a 1080p display. For this review I sat roughly 12ft from the screen and played some 4K content from an external blu-ray to test the picture. The colours are bright and vibrant and in the “warm2” setting, my personally favorite on Samsung TV’s, look very accurate to real life. The image is sharp and the level of detail in the higher resolution speaks for itself. Only issue was the dark scenes. I was watching at night in a very dim room and the blacks in general were not quite as deep as I would have liked. The contrast was ok and I could make out the scenes no problem, I just prefer a true black over dark grey. It’s better than a low end TV but not quite as good as a TV that has local dimming features instead of the artificial micro dimming.
Being a 4K TV it uses the Samsung UHD upscaling engine to convert 1080 and 720p content to the native resolution. I switched over to BBC1 HD after scanning for channels on the built in Freeview HD tuner. You can see the difference between that and true 4K content if you look closely but overall it handles the scaling well, maintaining a sharp high quality picture. If you go to standard definition content it gets slightly worse as you would expect but overall a very good result. Only noticeable issue on standard def content is the super small text on the bottom of adverts. Upscaling so heavily makes it slightly blurry but no one reads it anyway so it didn’t bother me. The same is true on my top end 55 inch Sony, so to some extent it’s unavoidable.
The panel has a refresh rate of 60Hz but also uses auto motion plus to artificially inject additional frames to smooth the image. With the motion handling switched off the motion blur was minimal to nonexistent with fast moving objects holing their original shape. There is some judder with a 1080 24p movie due to the mismatch of refresh rates but it’s only noticeable if you look for it in fast panning shots. Overall motion blur, or lack of it, scores very well.
The viewing angles are good up to about 30 degrees of centre. The picture stays vibrant with colour only noticeably fading from the blacks turning them a dark grey. After that point all the colours start to drain however it’s unlikely you would be viewing the TV from such an angle on any regular basis so overall it scores well for viewing angles.
I did tested the input lag with a result of 28ms in game mode. That’s the best result I’ve seen this year followed closely by the JU6000 making these new 4K Samsung models great for gaming. I hooked up my PS4 to give it a full test and combined with the 60Hz frequency it was a really positive experience. Highly recommended for frequent gamers.
Like many mid range Samsung models the TV is equipped with 2 x 10W speakers in either side of the rear. Due to the flat nature of the panel the sound quality on LED TV’s is usually average at best. The UE48JU6400 sits in the middle. Voices and ambient background music/sounds are clear and with the size of the panel you do get a slight notion of sound leaving each side of the TV giving slightly more surrounded feeling. It does however lack any base and will distort the low notes if you take the volume up really high. For a living room TV the sound is passable but if you want real immersion then I would suggest hooking up an external sound system.
The Samsung can be connected to the home network via a wired ethernet cable or wifi giving you access to the many smart features it has to offer. Like all Samsung TV’s this year it’s running the Tizen operating system which is quite possibly the best smart network of all the major brands right now. The smart hub offers all of your catch up TV apps as well as on demand streaming services in a neat, easy to use interface. The quad core processor didn’t struggle and everything loaded quickly so no complaints there.
Finally you have the audio connectivity. You have the standard digital audio output for an external audio system as well as a 3.5mm headphone jack. As this is a slightly higher end TV from Samsung it also comes with the sound connect features meaning you can hook up audio devices via bluetooth as well.
The remote is exactly the same as the J6300 i tested recently. It’s again another upgrade over the more simplistic JU6000 remote having a smart hub button in the centre for quick access to your apps. The remote is long but sits comfy in the hand with a rounded back. The buttons are medium to large and it’s not overloaded meaning everything is simple to work out and function.
The Tizen operating system is customisable and more importantly simple to use. It doesn’t carry extra baggage making it fast and responsive. If you have someone in your family less tech savvy that will be a primary user, then I would advise going for a Samsung. The general user interface including settings menus and guide are also very easy to navigate.
The Samsung UE48JU6400 is a well equipped with a large offering of connectivity and all the network features you could ask for. On top of that you have the bluetooth audio connection and easy sharing allowing you to display music, pictures and video on the big screen from your smartphone or tablet over the network. The Samsung also comes with the standard USB features which include playback and extended PVR allowing you to record, pause and rewind live TV if you attach an external hard drive. To wrap it up there’s a single Freeview HD tuner but unfortunately no freesat tuner. You have to go right to the top end models to find a freesat tuner. Overall it’s a well equipped TV.
