Samsung’s KU6300 class offers a range of 4K UHD LED backlit LCD Smart TVs with HDR including a 65’’ option – UN65KU6300; a 60’’ option – UN60KU6300; a 55’’ option – UN55KU6300; a 50’’ option – UN50KU6300; and a 40’’ option – UN40KU6300.

Appearance and Design
The KU6300 has a nice design with a half inch border charcoal black matte frame surrounding the screen. The screen is 2.5” in depth so pretty thin for wall mounting.

Key features

The KU6300 4K LED TV from Samsung is one of the best priced 4K offerings from Samsung but still offers value for money – smart TV, UHD Picture Dimming, quad core processor, HEVC 4K streaming decoding, and a contrast enhancer. Though the 6300 has 4K UHD resolution, it rivals 1080p TVs of the same size from a year or two ago in price, one of its best features.

The Auto Motion Plus feature is something that comes as a blessing and a curse. By default it is set to On in all of the preset picture setting modes. You will likely want to turn it off for streaming content, DVDs, Blu-rays, and TV shows. You'll immediately see judder when you disable it, but your eyes will adjust momentarily. The features do not hurt good quality live sports programming so you may want to use it there.

Samsung Smart Hub
The KU6300 does not get the top Samsung Tizen OS Smart Hub of the top models, but instead gets a similar Smart Hub suite with the same basic design. It allows for individual logins so different members of the family can have different recommendation settings. This is a big plus for a home with multiple TV users. The Smart Hub for the KU6300 includes a full web browser.

Quad-core Processor
The quad-core processor greatly increases the speed of the Smart TV function and browsing. It is a welcome addition since processing speed and multitasking were slow before the upgrade to the quad-core.

Smart Remote
The KU6500 has a nice upgraded remote control complete with touchpad or 5-way controller. It helps with browsing and streaming TV functions.

Sound Quality
There is plenty of volume from the inbuilt 10W speakers. It's not what I would call high quality defined audio, but it gets the job done

Other Features
The KU6300 is DirecTV ready for 4K content. The TV has built in Wi-Fi, and plenty of HDMI inputs (4) and 3 USB inputs. It also has mobile to TV mirroring and a Game Picture Mode for gamers. You will also be able to display some types of HDR content on the screen, even though the TV does not have a wide enough color gamut to capture all the nuances of HDR.


As the lowest price Samsung 4K TV this year, value is an important aspect of this TVs appeal. Pricing is very appealing – around $1499 for the 65” version and $599 for the 40” size.

Picture quality

  • Only 60Hz so there is some judder with Automotion turned off 
  • Bad side angle viewing contrast and color saturation
  • Aesthetic Appeal not a super high end look 
  • Slow starting time on some apps 
  • Small selection of preset picture modes
  • No motion blur from 1080p, 720p, but some with SD
    It’s widely known that LED backlit LCDs are not the ideal picture technology (even in 4K), however Samsung's semi clear coat screen is a big plus. Images are clear and color information is accurate. However, you can still expect some light bleeding over time – especially with very dark or black background scenes. 
    The colors pop very well for a LED TV and you can get the brightest peak whites on the market – this is an advantage if you are looking for a very bright screen.

    HD to UHD Upscaling and Conversion
    The HD to UHD scaling varies hugely among the different classes of 4K TVs. Naturally, the more expensive ones tend to have much better scaling but the KU6300 fares well for its price range. As scaling is very important, it’s good to get a well-done scaling job for your money, especially since most of the TV you watch will be streaming from Netflix, Amazon, HBO etc. so you need the TV to be able to create cleaner, sharper images in the best case.  

    LED Edge Backlight
    The light flow through created by the Samsung LED backlights has been a major positive for the last couple of years and continues with this UHD offering. It's one of the TVs best characteristics.

    Side Angle Viewing – Much Room for Improvement
    Color saturation and contrast do fade when viewing from off center though much more subtly than expected. In fact, the untrained eye will likely not see much difference in contrast saturation until around 15 degrees off center.
