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.

Our Verdict

7.4 Mixed Usage

Good TV for a mixed usage. It isn't bad at anything. It will work in any kind of rooms since it is versatile. It is especially good for video games and sports.

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

Average for watching movies in the dark. It has a good contrast ratio, but it lacks local dimming to make the blacks even darker. It also has a small judder when watching movies.

7.1 TV Shows

Above average for TV shows in a bright room. The screen can get brighter than average, but it reflects a bit more lights than most TVs. It upscales lower resolution content well.

7.3 Sports

Good for watching sports. However, the screen is not very uniform, which results in a bit of dirty screen effect on playing fields.

8.4 Video Games

Great for video games. Very low input lag of lag, and not too much motion blur.

7.2 HDR Movies

Although the KU6300 support HDR10 input, it does not really benefit from it, since it does not support a wide color gamut and it cannot really get highlight very bright.

8.0 HDR Gaming

Good for HDR gaming. Picture quality is good. Supports HDR10 but can't really benefit from it due to lack of local dimming and no support for wide color gamut. Input lag is low even in HDR mode. Motion blur is good.

6.9 PC Monitor

Works well to use as a PC monitor. It supports a wide range of resolution, even 4k @ 60Hz @ 4:4:4, and the input lag is very good.

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

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

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

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.

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.

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.

The range of colors the Samsung TV can display is only good enough for Rec. 709 content. Sending an HDR signal or settings the color space to native will not give you a wider color gamut.

The KU6300 can't display a wide range of colors and so can't reproduce much of the P3 or 2020 color volume.

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.

The motion blur is good, but not great. The response time is favorable, and the trail that is behind the logo has an average length that is faint. It does have PWM flickering, but it only occurs when the back light is below 10 out of 20.

Enabling 'Action Motion Plus' to 'Auto' will allow 30fps content become smoother, this cannot be said about 60fps content. Even though they advertise that it has '120Hz Motion Rate', this is a 60Hz TV.

Excellent for fast pace competitive gaming, it will definitely give you an advantage over other gamers. 'Game' mode has to be selected from the 'Special viewing modes' under the 'Picture' menu to get the lowest input lag.

Interface
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.

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.

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