This TV was replaced by the Samsung MU7600

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

The Samsung KU7500 is a 4k UHD TV, the curved equivalent of the KU7000. It offers the same good picture quality, with great dark scene performance due to the high native contrast ratio. Motion is also better than average thanks to the quick response time. It isn't all good though, as the picture quality degrades rapidly when viewed at an angle and the HDR performance is limited.

Design

Curved : Yes

The design is identical to the KU7000, but with a curved screen. It has brushed metal borders which look quite good, and the same shiny metal V stand. The textured back adds a nice touch. It looks more premium than the KU6300 or curved KU6500

Stand

The stand is made of metal, and in a similar design to most other Samsung TVs. It has the same cut and polish as the non-curved KU7000.

Footprint of the 55" TV stand: 13.1" x 37.3"

Back
Wall Mount : VESA 400x400

The back has a textured finish which looks good. It is a bit more interesting than most other TVs. This is the same as the KU7000 and similar to the high end KS9000 series. If wall mounted the connections are still quite easy to access from the side.

Borders
Borders : 0.51" (1.3 cm)

The borders have a brushed metal finish which looks quite good. They are also thinner than average which is nice.

Thickness
Max Thickness : 3.03" (7.7 cm)

The TV appears thicker when viewed at an angle due to the curved screen. It is thickest at the bottom, and may stick out a little bit if wall mounted.

7.5

Picture Quality

The picture quality of the Samsung KU7500 is good. The high native contrast ratio and the good black uniformity make this TV a good option for people who like to watch movies in a dark environment. Blacks are pretty deep with no clouding or light bleed visible even in the darkest scenes. For people with a bright room, the KU7000 will not be the best option, since it can't get really bright to combat glare and the screen finish does an average job with reflection. Upscaling is as good as with other Samsung TVs and gray uniformity is average, but dirty screen effect is kept to a minimum and should not be problematic, even for big sport fans. Viewing angle is also average, but is on par even with Samsung's higher end TV models. HDR performance is impeded by the lack of real local dimming and by the low peak brightness, even though the TV has a wide color gamut and is free of banding.

8.9 Contrast
Native Contrast
:
5555 : 1

The native contrast ratio is good on the KU7500 and it provides good dark scene performance with deep blacks.

0 Local Dimming
Local Dimming
:
No
Backlight
:
Edge

Even if Samsung markets this model as having "UHD Dimming", this is not a local dimming feature. It reduces the whole screen brightness when a small highlight is present on screen. The effect can be noticed on our peak brightness result, where any measure of the brightness under 20% screen ratio starts to get less bright.

The SDR peak brightness is, as the HDR peak brightness, bellow average. Small bright highlights get reduce by what Samsung call 'UHD Dimming,' but this is less problematic while watching SDR content versus HDR content. Overall, this TV is not very bright and would be best situated in a dark room.

The peak brightness is below average for the KU7500 and is in line with the results that we got for the KU7000. Even if there is no local dimming, both of the smaller size windows get dim automatically by what Samsung call 'UHD Dimming'. This dimming can only be disabled if the TV is set to PC mode. Even when the TV is set to PC mode, the peak brightness is still low and will not be high enough to provide good HDR performance compared to other Samsung TVs in the KS Series that can obtain over a 1000cd/m² of brightness on the 2% size windows.

7.3 Gray Uniformity
50% Std. Dev.
:
3.497 %
50% DSE
:
0.175 %

Gray uniformity is average and luckily not too much dirty screen effect is visible. All borders are darker with a large vertical band in the center being a bit more bright and warm. Dirty screen effect is not too obvious and even if there are some uniformity issues, the overall screen looks pretty smooth.

4.9 Viewing Angle
LCD Type
:
VA
Color Shift
:
35 °
Brightness
:
41 °
Black Level
:
18 °

The viewing angle is average for the KU7500 and is the same as the flat KU7000. When compared to other VA TVs, the KU7500 performs as well as the best, such as the Samsung KS8000. This is still not much when compared to IPS or OLED TVs. When viewed from off center, contrast ratio goes down, the picture quality get reduced a lot and the colors start to get washed out and get a reddish tint.

Update: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results.

9.1 Black Uniformity
Native Std. Dev.
:
0.885 %

Black uniformity is very good for this set and is comparable to the flat sibling, the KU7000. When looking at our test picture, some really faint clouding can be seen near the center, but this is really negligible and is only visible, since our test is really demanding. When watching a movie or just normal TV, no problems can be seem at all.

9.5 Gradient
Color Depth
:
10 Bit

When displaying our gradient test picture, the resulting image is pretty smooth and without any banding normally associated with an 8 bit panel. When analyzing our test picture of the gradient, no particularly problems can be seen, even in the darker shades, where problems are usually more present.

7.9 Pre Calibration
White Balance dE
:
4.19
Color dE
:
3.38
Gamma
:
2.18

Prior to calibration the results are good. The target 2.2 gamma is tracked very well, but the image is a little bit too warm. For most people a calibration is not necessary.

9.8 Post Calibration
White Balance dE
:
0.20
Color dE
:
0.65
Gamma
:
2.2

The calibration is very easy with the built in 10 point system. All minor issues could be fixed, and the TV feels responsive to changes.

You can see our recommended settings here.

8.0 480p Input

Low quality content such as DVDs look quite good. There are some halo artifacts along straight lines, but this is not as pronounced as some other TVs.

8.0 720p Input

720p content such as cable looks good. Details are preserved well and the image isn't too soft.

9.0 1080p Input

1080p content such as Blu-rays look good. The image is sharp and details are clear.

10 4k Input

High resolution content such as UHD Blu-rays look great, and no issues can be seen.

Screen Finish
:
Semi-gloss

The KU7500 is average at dealing with reflections. Due to the semi-gloss finish, direct reflections are large and diffused across the screen. This helps to reduce their intensity, but will be an issue for a room with a few direct reflections. For a darker room this is not an issue.

6.0

Motion

Motion blur is better than average due to the fairly quick response time. This results in good performance for fast moving scenes. When watching movies on the TV some small judder is always present. This is not an issue for most people as it is generally not noticeable except for people who are more sensitive to it. The TV has some motion interpolation options for people who enjoy the soap opera effect.

7.6 Motion Blur
Response Time
:
19.4 ms
Overshoot
:
0 ms

The response time is better than average, and provides good motion performance. For fast paced content some blur can be seen but it should be a good enough result for most content. The backlight flicker due to PWM dimming can be seen in the duplications following the logo.

2.8 Image Flicker
PWM Dimming Frequency
:
120 Hz

:
Yes
BFI Frequency

The KU7500 uses PWM to dim at 120Hz. It is possible to enable a 60Hz flicker to clear up motion, but this isn't available in the 'Game' special viewing mode.

0 24p Playback
Judder-free 24p
:
No
Judder-free 24p via 60p
:
No
Judder-free 24p via 60i
:
No

Judder is present when playing movies from any source. Most people don't notice judder so this isn't an issue.

5.0 Motion Interpolation
Motion Interpolation (30 fps)
:
Yes
Motion Interpolation (60 fps)
:
No

Those who enjoy the soap opera effect are able to enable it for 30fps content. The TV has a native 60Hz panel and so can't interpolate content past this.

8.2

Inputs

The input lag is relatively low across all sources, which is great. This should not be an issue even for the most sensitive users. The KU7500 supports most of the demanding resolutions, which is great for PC users. It has a 60Hz panel and so can't display a 120Hz input.

Sound Quality

The overall sound quality is slightly below average. Although the frequency response is quite good for a TV, there is distortion which increases as the volume rises. For people who don't care about the sound quality it should be ok, but otherwise a low-end soundbar would be an improvement.

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.

Average performance. Frequency response is decent at lower volumes, however, there is a noticeable amount of compression and pumping present under heavier loads. Additionally, low-end cutoff and maximum loudness are also decent.

5.9 Total Harmonic Distortion

:
0.018
Distortion @ 80
:

Smart Features

Smart OS : Tizen (2016)

The KU7500 has Samsung's Tizen smart platform, which is great. It works well and is very easy to use. In the initial TV setup it will attempt to identify connected devices for CEC control which makes the setup very easy. After initially turning on the TV, it can take 10-15 seconds to be able to use the smart platform, but this isn't long enough to be an issue for most people. The platform looks good and allows access to the Samsung app store which has plenty of content including Netflix, Amazon Video and Vudu. Plugging a USB drive directly into the back of the TV allows easily playing photos or videos.

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.

Apps

The Samsung app store allows access to a wide variety of apps to suit almost any media use, including Netflix, Amazon Video, Spotify and YouTube.

TV Controls

A single button to control the TV is located under the right hand side. It allows for basic operations such as power, and changing inputs or volume. It is easy to access if wall mounted but can be difficult to use, as each operation requires a combination of pressing and holding the button.

Differences between Sizes and Variants

We tested the 55" (UN55KU7500). For the most part, we expect our review to be valid for the 43" (UN43KU7500), 49" (UN49KU7500), 65" (UN65KU7500).

Note that the UN78KU7500 has a full-array backlight, so we expect it to offer better dark scene performance but worse gray uniformity.

If someone comes across a different type of panel or if their Samsung KU7500 doesn't correspond to our review, let us know and we will update the review.

43" UN43KU7500

Compared to other TVs

Top left: Samsung KU7000 (UN55KU7000). Bottom left: Sony X850D (XBR55X850D). Middle: Samsung KU7500 (UN55KU7500). Top right: Vizio P Series 2016 (P65-C1). Bottom right: Samsung KS8500 (UN55KS8500).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung KU7500 has good picture quality, and works well as an all-round TV. It is almost identical to the Samsung KU7000, but without the curve so the increased price is hard to justify. With this price premium, it is competing with higher end TVs offering more premium features so it can be a bit hard to recommend the KU7500. Unlike the KU7000, it is available in a 78" variation which may offer good performance for the price.

7.4 Mixed Usage

Better than average TV for a range of usages. Picture quality is good, especially in a dark room but lacks features such as local dimming to improve it further. Handles fast motion well but unfortunately the colors lose saturation and the image loses contrast when viewed at an angle.

6.8 Movies

Slightly below average for watching movies in a dark room. Dark scene performance is good, but lacks local dimming to improve it even more. Those sensitive to judder will notice it when watching movies. For most people this isn't an issue.

7.2 TV Shows

Slightly better than average for watching TV in a bright room. Picture quality is good, but degrades when viewed at an angle. Can't get very bright to deal with glare, and is average at handling reflections. Smart platform works well for casual watching.

7.3 Sports

Good for sports fans. Picture quality is good, but degrades at an angle. Uniformity is a bit better than average, so not much dirty screen effect should be visible. Motion blur is better than average which is good.

8.2 Video Games

Great for gamers. Picture quality is good, and response time is low which results in less motion blur than average. Input lag is low, which is good.

7.5 HDR Movies

Average for HDR movies. Supports HDR10, but lacks some features such as local dimming to improve dark scene performance. Picture quality is good, and supports a wide color gamut. Can't get bright highlights.

8.0 HDR Gaming

Great for HDR gaming. Picture quality is good, and TV supports the HDR10 format. Doesn't support local dimming to improve dark scene performance, or to increase brightness of highlights. Supports a wide color gamut and HDR input lag is low, which is good.

7.0 PC Monitor

Good choice as a PC monitor. Picture quality is good but degrades when viewed at an angle. Supports chroma subsampling for clear text across all backgrounds. Input lag for PC use is quite good, and there is less motion blur than average.
