When it matters: Different technologies have different performance and are suited to different uses
Good value: IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
:
VA
Resolution : 4k

The Samsung Q7CN is a 4k QLED TV with very good picture quality. It can get very bright and has excellent reflection handling that makes it suitable for a bright room. When in HDR, it can display rich colors with saturated highlights due to the very wide color gamut. It has low input lag and variable refresh rate support that make it a good choice for gaming. Although the TV has a high native contrast ratio, dark room performance is hurt by the not so effective local dimming. Unfortunately, the image deteriorates when viewed at an angle and only those sitting directly in-front will enjoy the best picture quality.

Design

Score components: Subjectively assigned
Samsung Q7CN Design Picture
Curved : Yes

The design of the Samsung Q7CN is excellent. It is identical to its flat counterpart the Samsung Q7FN. Literally, the only difference in terms of design is the curved profile of the Q7CN, which is also reflected in the shape of its stand. All other aspects including the thin side look, the metallic tint of the stand and of the borders, and of course, the great build quality, are the same.

Stand
Samsung Q7CN Stand Picture

The stand's base follows the curve of the screen. In all other aspects, it is identical to the stand of the Q7FN and supports the TV well. Just like all center stands, it cannot completely eliminate wobbling, but this should not be an issue.

Footprint of the 55" TV stand: 31.5" x 11.75"

Back
Samsung Q7CN Back Picture
Wall Mount : VESA 200x200

The back of the Q7CN looks identical to the Q7FN. It is plastic with a matte finish and small horizontal grooves that span from one side to the other. One of the advantages of the One Connect box is that it eliminates the need for sophisticated cable management, as there is only one single cable that connects to the TV and that can be easily routed through the stand. This is especially helpful if you wish to place the TV far from the rest of your electronics (game console, AV Receiver, etc).

The size of the One Connect box is: 15.35'' x 5.12'' x 2.64''

Borders
Samsung Q7CN Borders Picture
Borders : 0.35" (0.9 cm)

The borders of the Q7CN are very thin. They have a metallic finish and look exactly the same as the Q7FN.

Thickness
Samsung Q7CN Thickness Picture
Max Thickness : 3.25" (8.2 cm)

The Q7CN is a thin TV, just slightly thicker than its flat counterpart, and that's due to the curve. You can easily wall mount it and it will not protrude much.

8.0 Build Quality
Samsung Q7CN Build quality picture

The Q7CN has a great build quality exactly like the Q7FN with no obvious gaps or loose ends. It is mostly plastic, with some metal parts, like the stand and the borders, that contribute to its solid feel.

7.9

Picture Quality

The picture quality of the Samsung Q7FN is very good. It has a high native contrast ratio, but the inefficient local dimming hurts dark room performance. The Q7CN, just like the Q7FN, can get very bright and can handle the reflections of a bright room well, so it is a good choice for brighter environments. The TV has a very wide color gamut and will display rich and bright highlights when showing HDR content. Unfortunately, the viewing angles are bad and the image deteriorates when viewed from the side. 

8.8 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:

Excellent contrast ratio for the Q7CN. Surprisingly it is slightly lower than its flat version the Q7FN. Unfortunately, local dimming does not seem to add much to the contrast ratio.

1.8 Local Dimming
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned
Local Dimming
What it is: Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters: On LED TVs only. Dark scenes viewed in a dark room.
:
Yes
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
:
Edge

The local dimming performance is bad. Mainly due to the edge lit LED panel and due to the poor algorithm. This is a very similar performance to the Q7FN, the Q6FN, the NU8000 and many other Samsung models of 2017 and 2018 as you can see in the tooltip histogram next to the test name.

The Q7CN has an excellent SDR peak brightness. Just like the Q7FN it does not reach the brightness of the Vizio P Series Quantum or the is Sony Z9F, but still is a great choice for a bright room. The brightness level is good in most window sizes but it is exceptionally high in darker scenes with small bright highlights. This behavior is similar to the Q7FN.

The menu option that controls the luminance on this Samsung Q7FN is called Backlight.

Very good gray uniformity for this Q7CN. In line with most other 2018 Samsung models and better than more expensive models like Samsung Q8FN. There is a little clouding in the two sides of the screen and you might notice a few shades here and there when you are watching a sports field but nothing serious.

In the darker scenes the uniformity is even better with no noticeable clouding nor any dirty screen effect.

The viewing angles of the Q7CN are just as bad as the ones found on most of the other VA panel TVs. Colors shift significantly and blacks intensify significantly at around 20 degrees. And at about 33 degrees off center, brightness level has already dropped by 50%. Unfortunately, Just like all curved TVs, when sitting off-axis, the curve of the screen does cause one side to be more accurate as it is angled towards you, while the other side is at a greater angle and the image is less accurate.

The black uniformity of the Q7CN is very good. When local dimming is disabled through the service menu, some backlight bleed is visible all over the screen. However, with local dimming on high, the black uniformity worsens. This happens because on edge-lit TVs like the Q7CN, the local dimming zones are vertical. Those vertical zones darken the edges, but the center remains grayish, so the overall image is less uniform.

Out of the box, the Q7CN has a decent overall accuracy when set to the 'Movie' picture mode. The white balance dE is high and most enthusiasts will notice the inaccuracies. The Color dE is quite low, better than the Q7FN and one of the best in this year's lineup. Looking at the gamma, we see that for the entire brightness range of stimulus the Q7CN is darker than our target and this results in darker scenes. The manufacturing calibration was not targeting a gamma of 2.2. Finally, the color temperature is pretty good, close to 6500K

9.4 Post Calibration

A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.
When it matters: To get the most accurate picture when watching TV shows, movies or video games. This is particularly for skin tones.
Good value: 6500K

Excellent post calibration color accuracy for the Q7CN. Calibration was done in the 'Movie' Picture mode, and we used 100% window instead of the usual 18% so that local dimming would not interfere with our white balance measurements. Unfortunately, the color space management is not very responsive and as you can see most of the correction was due to the white balance correction which was also the most erroneous one. The white balance dE after calibration was too small to spot any inaccuracies. The color dE was not diminished much but it was already low so not many will be able to spot any color errors. Gamma was brought to the 2.2 target and followed our input stimulus well. The color temperature, however, became a little colder with an almost unnoticeable bluish tint.

Samsung Q7CN EOTF

Excellent wide color gamut. The TV lies at the top of the list along with the Q7FN. The Q7CN fully covers the DCI P3 color space and has the best coverage of the Rec.2020 color space we have measured so far. You can expect excellent HDR performance from this TV.

The EOTF follows the PQ curve perfectly until the TV's peak brightness where it rolls off without flattening. This results in less clipping of the bright scene highlights. The PC and Game EOTFs are not following the input stimulus as accurately. You might notice some scenes being brighter, whereas others being darker.

If you find HDR content too dim, then you can set Contrast Enhancer to 'High' and this will raise the EOTF and brighten most HDR scenes.

Motion

The Samsung Q7CN has excellent motion handling. It has a very fast response time that leaves only small blur trailing fast content, but also might make movies a little stuttery. It has a very good black frame insertion feature, can remove judder from any source and supports variable refresh rate making it a great choice for gaming enthusiasts. Unfortunately, it is not flicker-free, and furthermore, its flicker behavior changes depending on the TV settings and this might bother some flicker sensitive people.

The Samsung Q7CN has an excellent response time. It has some overshooting in the 0-80%, 0-20%, and 20-80% transitions, which is very similar to the overshooting observed in the Q7FN. However, these are hardly noticeable in normal use. The fast response time leaves on a small blur trail in fast-moving content.

6.0 Flicker-Free

When it matters: All usages, but particularly when viewing fast motion (such as in sports and video games) or when using the TV as a PC monitor.
Good value: 0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
:
240 Hz

The Q7CN, just like its flat counterpart, the Q7FN, use PWM flicker to dim the backlight. Unfortunately, the frequency at which the backlight flickers is only 240Hz and this might bother some people.

The backlight does not always flicker at 240hz as explained here.

The left side of the screen has a slightly different strobe pulse timing than the right side; the left side flickers ~2 ms earlier than the right side. This was confirmed at 240 Hz, 120 Hz, and 60 Hz flicker frequencies. This results in motion looking slightly different on the left and right sides of the screen, with the difference being most noticeable with 120 Hz flicker, however, it will be very difficult to notice with normal content.

9.3 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.

The Q7CN has an optional BFI feature that can help clear blur. To enable it you must first set Auto Motion Plus to 'Custom', and then enable LED Clear Motion. This makes the backlight flicker at 60Hz and that makes motion look crisper. However 60Hz flicker is noticeable and some people might be bothered.

The Q7CN's flicker frequency changes depending on the TV's settings, as we've seen with the other QLEDs like the Q7FN. When sent a 60 Hz signal the TV has the following flicker frequencies:

  • 240 Hz flicker in the 'Movie' picture mode
  • 120 Hz flicker when Auto Motion Plus is enabled
  • 120 Hz flicker in 'Game' mode
  • 60 Hz flicker when LED Clear Motion is enabled

The Q7CN supports most common resolutions with the exception of 1440p @ 60hz. However, it does support 1440p @120Hz just like the rest of 2018 Samsung QLEDs.

Chroma 4:4:4 for PC use is supported. However, it is necessary to enable HDMI UHD Color from the External Device Manager for the port used and the input label must be set to 'PC'. The Q7CN should automatically detect when a PC is connected and change the label accordingly.

The frequency response of the Q7CN is decent. LFE (low-frequency extension) is at 71Hz, which is above-average. This means the bass of this TV will have a decent about of body and punch to it, but won't be able to produce any low-end thump and rumble. The response above the LFE points is well-balanced, which is important for a clear and intelligible reproduction of dialog. However, this TV doesn't get very loud, so may not be loud enough for large and crowded places.

Differences between Sizes and Variants

We tested the 55" Samsung Q7CN (QN55Q7CN) and we also expect our review to be valid for the 65" version (QN65Q7CN).

If someone comes across a different type of panel or if their Samsung Q7CN doesn't correspond to our review, let us know and we will update the review. Note that some tests such as gray uniformity may vary between individual units.

65" QN65Q7CNAFXZA QN65Q7CNAFXZC VA 120Hz

The model we reviewed was manufactured in August 2018.

The Samsung Q7CN is the curved version of the Samsung Q7FN which we have reviewed earlier in the year. The two TVs are almost identical in design and in performance.

Compared to other TVs

Samsung Q7CN Group Shot Picture
Top left: Samsung Q6FN (QN55Q6FN ). Bottom left: Samsung Q7FN (QN55Q7FN). Middle: Samsung Q7CN (QN55Q7CN). Top right: LG SK9500 (65SK9500). Bottom right: Sony X900F (XBR55X900F).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung Q7CN is a TV with a very good performance that will please most people.

Sony X900F
49" 55" 65" 75" 85"

The Sony X900F is slightly better than the Samsung 2018 Q7CN QLED TV. The X900F has a much better dark room performance due to the efficient full array local dimming. The Samsung Q7CN, on the other hand, has a lower input lag and support for gaming features like auto low latency mode and FreeSync, which make it a better choice if you play a lot of games. Finally, the Q7CN can handle reflections slightly better.

Samsung Q7FN
55" 65" 75"

The Samsung Q7FN and the Samsung Q7CN both have very similar performance. The Q7CN is the curved version of the Q7FN. Most of the differences between them can be attributed just to panel variance.

Samsung Q8C
55" 65" 75"

The Samsung Q7CN is somewhat better than the Samsung Q8C. The Q7CN has better black uniformity that matters when you watch dark scenes in a dark room. The Q7CN can also overcome the glare of a bright room better since it can get significantly brighter. Finally, the Q7CN is a better choice for playing video games as it has lower input lag and supports the FreeSync variable refresh rate.

LG SK9500
65"

The Samsung Q7CN is a bit better than the LG SK9500, unless you will be watching from the side, in which case the LG is a better choice due to the wider viewing angles. When sitting directly in front, the Samsung Q7CN has deeper blacks in a dark room due to the higher native contrast ratio and better black uniformity. The Q7CN also has better gray uniformity and is better at handling bright room reflections. Finally, the Samsung Q7CN is a better choice for HDR gaming due to the lower input lag and support for the FreeSync variable refresh rate.

Conclusion

B&H

8.2Mixed Usage
What it is: General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
The Q7CN is a great TV for mixed usage. It is a very good TV for watching TV shows as it can get very bright and a great TV for watching sports since it has a very fast response time and excellent motion handling. Watching movies is also a good experience although the poor local diming will not allow you to enjoy deep blacks in a dark room. Finally, it is an excellent TV for playing video games or for use as a PC monitor as it has a low input lag and great gaming features like FreeSync variable refresh rate support.
7.6Movies
What it is: Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
The Q7CN is a good TV for watching movies. Although you will not get the deepest blacks in a dark room, the TV has a very wide color gamut and excellent motion handling features like motion interpolation and 24p judder removal. It has decent out of the box color accuracy and you can always make it perfect with the help of a professional calibration. Upscaling of Blu-rays is excellent, and native 4k content looks perfect.
8.3TV Shows
What it is: TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
This a very good TV for watching TV shows. It can handle the reflections of a bright room well and at the same time, it can get bright enough to fight glare. Unfortunately, the viewing angles are not good and you will notice some image degradation if you are moving around doing house chores while watching your favorite TV show. However, the TV has good upscaling of cable content, and a good smart platform with many apps to help you find your favorite shows without much hassle.
8.2Sports
What it is: Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
The Samsung Q7CN is a very good TV for watching sports. If you place it in a bright room with many light sources, you will not have any problems as it can get very bright and at the same time, it can handle reflections very well. It has a very fast response time and fast action in sports like hockey look great with very little motion blur. Unfortunately, the image deteriorates if you are watching from the side so it is not a good option for a room with wide seating arrangements. Upscaling cable content looks good and due to the TVs good gray uniformity, the pitch will look uniform with hardly any shades or clouding.
8.8Video Games
What it is: Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
This is an excellent TV for playing video games. The Q7CN has a very low input lag even when it is interpolating low fps games, or even when it is engaged it a FreeSync mode. The response time is fast and you will hardly notice any motion blur. The TV has excellent 1080p upscaling for those older consoles and perfect native 4k display for the newer ones. It has a good native contrast ratio, but can't display deep blacks in a dark room due to the inefficient local dimming. You can instead place it in a bright room where it will fight glare and handle reflections very well, offering you an exciting gaming experience.
7.8HDR Movies
What it is: HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
The Q7CN performs very well when you watch HDR movies. Although the blacks are not very deep in a dark room due to the inefficient local dimming, you will enjoy the rich colors and the bright highlights this TV offers you when displaying HDR content. It can get very bright, so most scenes will look close to what the creator intended. This is something that only a few TVs, from the ones we've tested, can deliver.
8.5HDR Gaming
What it is: HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
This is an excellent TV for playing HDR games. It has a very low input lag when displaying HDR content and a fast response time to closely follow fast action scenes with minimal blur. Although dark room performance is not the best out there, the rich colors and the bright highlights this TV can display will make your HDR gaming experience a memorable one. This Q7CN also incorporates many nice goodies to further improve your HDR gaming experiences like support for black frame insertion or FreeSync.
8.5PC Monitor
What it is: PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
The Q7CN is an excellent TV for use as a PC monitor. It has a very low input lag that allows it to respond immediately to your actions like moving the mouse around the screen. At the same time, the fast response time only leaves a small motion blur trail behind it. The TV can display crisp text as it supports chroma 4:4:4 and there is no risk of any permanent burn-in when you display the same OS interface for extended periods of time. Unfortunately, the edges of the screen might look slightly dark when you sit close to the TV as the viewing angles are poor and will cause uniformity issues.
