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.

Score components: Subjectively assigned
Samsung KU7500 Design Picture
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
Samsung KU7500 Stand Picture

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
Samsung KU7500 Back Picture
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
Samsung KU7500 Thickness Picture
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.

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.

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 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.

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.

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.

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.

Samsung KU7500 Smart TV Picture
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.

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.

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.

Samsung KU7000
40" 43" 49" 55" 65"

The Samsung KU7000 offers the same good picture quality, with a flat screen. It has the same good motion performance and the picture also degrades when viewed at an angle. As the curved screen doesn't improve the picture quality, it's easier to recommend the Samsung KU7000 at the lower price.

Sony X850D
55" 65" 75" 85"

The Sony X850D has a better than average picture quality, but really stands out in a bright room with wide seating. It has a low native contrast ratio, but the image remains accurate when viewed at an angle. It also has better motion for fast paced content, but worse input lag for gamers. If you've got a dark room go with the Samsung KU7500, otherwise the Sony X850D is a better choice.

Vizio P Series 2016
50" 55" 65" 75"

The Vizio P Series 2016 is available at a slightly higher price, but provides much better picture quality with good local dimming to improve the dark scene performance. The motion blur and SDR input lag are also very good, so go with the Vizio P Series 2016 if you have a dark room. For a bright room, there are better TVs.

Samsung KS8500
49" 55" 65"

The Samsung KS8500 is a little bit more expensive, but offers more features as a high end Samsung TV. It offers better HDR performance as it can produce very bright highlights. It is also much better in a bright room as it has a coating which reduces reflections, and can get bright to combat glare. If you can afford it, go with the Samsung KS8500.

Hi, I am wondering if this KU7500 is worth buying more than the Vizio M43-C1 (2015 model) or not. I use it mainly as PC monitor and watch movies and play games a lot with my GTX 1070s in SLI. May I ask which one have better images and color reproduction? Please help me to decide. Thanks!
Go with the Samsung KU7500. Since it has a wide color gamut, you will get more saturated colors when paired with your GTX 1070, since this video card can do HDR. It also has some pretty good input lag result, which is especially good for gamers.

Hi, love this site; I am looking for a TV specifically for HDR gaming. Between the Samsung KU7500 and the Sony X800D, which would you recommend?
For 50" the KU7500 is better because the 49" X800D uses an IPS panel with poor contrast and black uniformity. The X800D is only better if you want to use black frame insertion in game mode; this flickers the backlight at 100 Hz which reduces motion blur but the flickering may be bothersome.
For 43" the KU7500 is slightly better than the X800D because of its 10 ms lower input lag, unless again you want to use black frame insertion in game mode.
