This tv was replaced by the Samsung MU6300

Type : LED
Resolution : 4k
Refresh Rate : 60 Hz

The 4k Samsung KU6300 Series UHD LED TV doesn't have a stellar picture quality but is good enough for most content. It supports an HDR input, but it doesn't have the capabilities to display a more colorful picture. It also suffers from bad reflections and constant judder on movies. When watched from the side, its picture quality also diminishes.

Pros
  • Low input lag
  • Great blacks and contrast ratio
Cons
  • Reflects more lights than average
  • Average gray uniformity
  • Judder is present in movies

Design

Score components: Subjectively assigned
Samsung KU6300 Design Picture
Curved : No

The Samsung KU6300 delivers the same look and design as last year's Samsung J5000, J5200 and J5500, keeping it simple for a standard budget television. The borders are still average, and the stand, while still stable, has a wide footprint.

Stand
Samsung KU6300 Stand Picture

The stand is quite stable, but has a large footprint.

Footprint of the 55" TV stand: 33.1" x 12.6"

Back

Wall Mount : VESA 400x400

The backing of the Samsung TV has a nice plastic design to it. The ports, which are located on the side, will be helpful when needing to have access to them while the TV is wall mounted.

Borders

Borders : 0.63" (1.6 cm)

The borders are made up of reflective plastic that will attract finger prints easily.

Thickness

The thickness of the KU6300 is about the same as last year's model Samsung JU6500.

7.4

Picture Quality

Score components:

The Samsung KU6300 has a good picture quality overall. High quality content like Blu-rays appears richly detailed and lower quality content like DVDs and cable TV doesn't look bad at all. Even with the lights out, dark scenes appears deep, thanks to its high contrast ration and good black uniformity. The KU6300 does have some down sides though. The viewing angle is limited due to the VA panel it's using and its gray uniformity is also not so great. 

8.9 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.
Score components:
Samsung KU6300 Checkerboard Picture
Native Contrast

When it matters: Dark scenes in a dark room.
Good value: > 3,000
Noticeable difference: 500
:
5411 : 1

The blacks are deep on the Samsung KU6300, which offers a high contrast ratio and a better picture quality.

The TV achieves a pretty average peak brightness when maxed out, and HDR is on. When an image is displayed throughout the entire screen, it stays bright, which is great.

Update 02/08/2016: Under the latest firmware, the 'CE dimming' is stronger than before and the peak brightness of the 2% and 10% windows is now less than what we measured when we first did the original review.

:
10 Bit

The Samsung KU6300 can display our gradient test image fairly well. On our test picture, the gradation is smooth overall in the light shades with some small anomalies in the darker shades, especially in the green color. But it should not be an issue in regular content.

Update 10/26/2016: Our original test was showing 8 bit gradations due to incorrect drivers on our system. After some correction to our test apparatus, we have retested the color depth and found that it is able to display a 10 bit gradient smoothly.

No image retention could be notice at all after running our test. Even on the first test picture, right after the 10 minutes exposure to the burn-in image, nothing was found after our computer analysis, which is great. This is in line with others VA TVs results and is good for people looking for a good TV for video games, to use as a PC monitors and for shop or office that need to display a lot of static contents.

Motion

This Samsung TV is not the best for handling motion. On one hand, it has some descent response time so fast pace action will look good on screen, without too much motion blur. But on the other, it is plague with judder issues for movies on all type of source and can only interpolate 30 fps since this is an 60Hz TV.

Sound Quality

Score components:

Sound on the Samsung KU6300 isn't that bad when it isn't at its maximum volume. Still, even a budget sound bar would be way better than the TV speakers and would be recommended for anyone that care about sound.

Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.

Decent frequency response. The low-end cutoff and the responses at 75dB and 85dB are good. However, maximum loudness and frequency response at maximum volume are subpar, since pumping and compression will be present.

Smart Features

Score components: Subjectively assigned
Samsung KU6300 Smart TV Picture
Smart OS : Tizen (2016)

Just like the Samsung KS Series, it includes the new Tizen 2016 platform, with some minor differences. In terms of the applications, the KU6300 has less pre-loaded application than the KS Series, this shouldn’t be a problem though since you can download them from the menu either way.  The performance slacks, as menus would freeze often for a lengthy duration, and the remote would flash and disconnect because of it.

When a new device is detected (such as when a computer is woken from sleep while plugged into an HDMI port) the TV automatically switches to this device. This may be an annoyance if you are watching other content at the time.

Remote
Samsung KU6300 Remote Picture
Remote : Smart

The remote is very similar to the Samsung KS series with some differences. The back of the remote has a reflective plastic that will easily track finger prints, unlike the Samsung KS Series gray reflective plastic, the buttons protrude out rather than being inwards and the volume up and down, as well as the channel up and down buttons are black rather than chrome. The remote also weighs less than the KS Series remote and lacks the microphone option.

Differences between Sizes and Variants

We tested the 55" (UN55KU6300) version FA01. For the most part, we expect our review to be valid for the other sizes of this model.

The KU6270 and KU6290 are variants of the KU6300. We expect them to have the same picture quality as the KU6300 reviewed. The only major differences are that the KU6270 and KU6290 lack Bluetooth connectivity and include a remote that looks identical to the KU6300 remote but lacks the features that use Bluetooth, such as pairing and Universal Remote Control.

Update 2017/05/12: The KU6270 does not have component/composite video inputs, but the KU6290 does.

If someone comes across a different type of panel or if their Samsung KU6300 doesn't correspond to our review, let us know and we will update the review.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung KU6300 has fierce competition in the budget range. It is a good choice if you want an affordable versatile TV.

Vizio D Series 4k 2016
40" 50" 55" 58" 65"

The Vizio D Series 4k 2016 is similar to the Samsung KU6300 but with a few key differences. It doesn't support HDR, has somewhat worse upscaling but offers local dimming and better motion. For high quality content, its picture quality is slightly better. Since it is sold for cheaper, most people should buy the Vizio D 4k 2016 except for those who watch a lot of low quality content like DVDs and cable TV.

Samsung JU6500
40" 48" 50" 55" 60" 65" 75"

Last year Samsung JU6500 shares lot of similarities with the KU6300. It doesn't support HDR and isn't as good for watching movies but it has slightly less blur which makes it a better option for sports.

Samsung KS8000
49" 55" 60" 65"

The Samsung KS8000 is definitely not in the same price range of the KU6300 and it shows. Its picture quality is way better no matter the content. It can get extra bright too so a better fit for the living room. If you have the money, don't hesitate to get the KS8000.

LG UH7700
55" 60" 65"

The LG UH7700 is also more expensive than the Samsung KU6300 but not always better. It is when the TV is viewed from the side but not from directly in front in a dark room. It is better suited for a wide living room with seating on the sides than for watching late night movies.
