55 Class Q7c Curved Qled 4k Tv Review

Exam Results

Design

Curved Aye

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 contour of the Q7CN, which is also reflected in the shape of its stand. All other aspects including the thin side look, the metal tint of the stand and of the borders, and of course, the great build quality, are the same.

The stand's base of operations follows the bend of the screen. In all other aspects, it is identical to the stand up of the Q7FN and supports the TV well. But similar all middle stands, it cannot completely eliminate wobbling, only this should non exist an issue.

Footprint of the 55" Telly stand: 31.5" x xi.75"

Wall Mount VESA 200x200

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

The size of the I Connect box is: xv.35'' ten v.12'' 10 2.64''

Borders 0.35" (0.9 cm)

The borders of the Q7CN are very sparse. They take a metal finish and look exactly the same as the Q7FN.

Max Thickness 3.25" (8.3 cm)

The Q7CN is a thin TV, just slightly thicker than its flat counterpart, and that'south due to the bend. You lot tin hands wall mount it and it will not beetle much.

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

Picture Quality

Native Contrast four,971 : 1

Contrast with local dimming 5,047 : 1

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

Local Dimming Yep

Backlight 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 every bit you can see in the tooltip histogram next to the test name.

SDR ABL 0.021

The Q7CN has an excellent SDR tiptop 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 pick for a bright room. The brightness level is good in most window sizes just it is uncommonly high in darker scenes with small bright highlights. This beliefs is similar to the Q7FN.

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

Very skilful HDR peak brightness. Although we measured just slightly lower brightness than its flat analogue the Q7FN, when the Q7CN displays HDR content, bright highlights in night scenes announced remarkably well, and at times within the 1000-4000 cd/chiliad² HDR target level.

50% Std. Dev. 3.147%

fifty% DSE 0.172%

v% Std. Dev. 0.786%

5% DSE 0.109%

Very proficient grayness uniformity for this Q7CN. In line with about other 2018 Samsung models and better than more expensive models like Samsung Q8FN. There is a fiddling clouding in the two sides of the screen and you might notice a few shades hither and at that place 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 dingy screen effect.

Color Washout 22°

Color Shift eighteen°

Effulgence Loss 34°

Black Level Enhance 24°

Gamma Shift eighteen°

The viewing angles of the Q7CN are just as bad every bit the ones plant on most of the other VA panel TVs. Colors shift significantly and blacks intensify significantly at effectually 20 degrees. And at about 33 degrees off middle, brightness level has already dropped by 50%. Unfortunately, Just like all curved TVs, when sitting off-axis, the curve of the screen does crusade i side to be more accurate equally information technology is angled towards you, while the other side is at a greater angle and the prototype is less authentic.

Native Std. Dev. 0.674%

Std. Dev. w/ L.D. 1.282%

The black uniformity of the Q7CN is very skillful. When local dimming is disabled through the service carte, some backlight drain is visible all over the screen. However, with local dimming on high, the blackness uniformity worsens. This happens considering on edge-lit TVs like the Q7CN, the local dimming zones are vertical. Those vertical zones darken the edges, but the center remains grayish, then the overall paradigm is less uniform.

Screen Finish Glossy

Total Reflections 1.6%

Indirect Reflections 0.5%

Calculated Straight Reflections 1.one%

The Samsung Q7CN has excellent reflection handling. Only like the Q7F, the glossy screen finish and the anti-reflection blanket diffuse nearly of the reflections making the TV a adept choice for a room with many light sources.

White Residuum dE iii.51

Color dE 2.66

Gamma two.27

Color Temperature half-dozen,205 Thousand

Pic Way Motion-picture show

Color Temp Setting Warm 2

Gamma Setting BT.1886 +2, Brightness +2

Out of the box, the Q7CN has a decent overall accurateness when set to the 'Film' film mode. The white balance dE is high and near enthusiasts will notice the inaccuracies. The Color dE is quite low, better than the Q7FN and one of the best in this twelvemonth'south lineup. Looking at the gamma, nosotros run into 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 non targeting a gamma of 2.two. Finally, the color temperature is pretty good, close to 6500K

Update 04/12/2019: This Television set was incorrectly measured with Brightness +2, instead of at 0. This simply has a small bear upon on the results (slightly dimmer dark scenes beneath about 30 IRE) and then we don't program to retest it.

White Remainder dE 0.28

Color dE one.35

Gamma 2.20

Color Temperature half-dozen,611 K

White Balance Calibration 20 point

Color Scale Yes

Auto-Scale Role Aye

Excellent mail service calibration colour accuracy for the Q7CN. Calibration was washed in the 'Movie' Picture mode, and nosotros used 100% window instead of the usual 18% then that local dimming would not interfere with our white residuum measurements. Unfortunately, the colour infinite direction is not very responsive and every bit you can come across near of the correction was due to the white remainder correction which was also the most erroneous ane. The white residue dE subsequently calibration was too small to spot any inaccuracies. The color dE was not macerated much simply it was already low so not many volition be able to spot whatever 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 blue tint.

See our recommended settings hither.

Upscaling of DVDs or other 480p content is practiced.

720p content is displayed without whatever issues.

Blu-rays and other 1080p content including non-4k console games are displayed well.

Native 4k content is displayed perfectly without whatever issues.

The pixel structure is identical to the Q7FN.

Wide Colour Gamut Aye

DCI P3 xy 99.56%

DCI P3 uv 99.39%

Rec 2020 xy 76.77%

Rec 2020 uv 83.72%

Excellent broad colour gamut. The TV lies at the acme of the listing along with the Q7FN. The Q7CN fully covers the DCI P3 color infinite and has the all-time coverage of the Rec.2020 color space we take measured so far. You can expect excellent HDR functioning from this Boob tube.

The EOTF follows the PQ curve perfectly until the Boob tube'due south peak brightness where information technology rolls off without flattening. This results in less clipping of the brilliant scene highlights. The PC and Game EOTFs are not following the input stimulus every bit accurately. Y'all might detect some scenes being brighter, whereas others existence darker.

If you find HDR content as well dim, then you can prepare Contrast Enhancer to 'High' and this will enhance the EOTF and brighten nigh HDR scenes.

At that place are no signs of temporary image retention on the 2018 Q7CN.

Permanent Burn down-In Risk No

We don't wait VA panels to experience permanent image retentiveness, as the VA panel in our long term test appears immune.

Motion

80% Response Fourth dimension 3.nine ms

100% Response Time 13.5 ms

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 like to the overshooting observed in the Q7FN. Notwithstanding, these are hardly noticeable in normal use. The fast response time leaves on a minor mistiness trail in fast-moving content.

Flicker-Gratuitous No

PWM Dimming Frequency 240 Hz

The Q7CN, but 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 correct side; the left side flickers ~2 ms before than the correct side. This was confirmed at 240 Hz, 120 Hz, and 60 Hz flicker frequencies. This results in move looking slightly different on the left and correct sides of the screen, with the departure being most noticeable with 120 Hz flicker, however, it will exist very hard to notice with normal content.

Optional BFI Yes

Min Flicker for sixty fps sixty Hz

60 Hz for 60 fps Yes

120 Hz for 120 fps Yes

Min Flicker for 60 fps in Game Mode threescore Hz

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

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

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

Motion Interpolation (xxx fps) Aye

Motion Interpolation (threescore fps) Yep

The Q7CN is capable of interpolating content all the way up to 120fps.

The TVs carte du jour that controls movement interpolation is called Auto motility Plus. When enabled the Idiot box flickers at 120 Hz equally explained here.

Frame Concord Time @ 24 fps 28.2 ms

Frame Concur Time @ 60 fps 3.2 ms

The Q7CN has some stutter when it displays 24p content. This is due to the fast response time and in line with its flat analogue the Q7FN. If you lot wish to remove stutter, you can enable motion interpolation.

Judder-Free 24p Yes

Judder-Free 24p via 60p Yeah

Judder-Free 24p via 60i Yes

Judder-Complimentary 24p via Native Apps Yes

This TV can remove judder from whatever source.

To remove 24p judder, you must from a Blu-ray, gear up Car Motility Plus to 'Custom' with both sliders set to '0'.

But like the Q7FN, the backlight changes depending on the movement processing options enabled every bit explained here.

Native Refresh Rate 120 Hz

Variable Refresh Rate Yes

HDMI Forum VRR Yep

FreeSync Yes

Thousand-SYNC Compatible No

4k VRR Maximum 60 Hz

1080p VRR Minimum < 20 Hz

1440p VRR Maximum 120 Hz

1440p VRR Minimum < 20 Hz

VRR Supported Connectors HDMI

The Q7CN supports FreeSync. We successfully tested information technology on our Xbox One S and our Radeon RX 580 GPU, in 1080p, 1440p and 4k resolutions. In accordance with the rest of the 2018 Samsung TVs, the 4k VRR range is narrower than the 1080p one.

To activate it, enable the Tv's Game mode and in the FreeSync settings cull the 'Ultimate' mode that has the widest range. If you experience issues with 'Ultimate', then go to the 'Basic' mode.

8k with VRR N/A

Auto Low Latency Style (ALLM) Yeah

1440p @ 120 Hz: nine.2 ms

Excellent low input lag beyond all resolutions and refresh rates within Game Style. The input lag exterior of Game Mode is high, so if input lag is of essence make sure you are in Game Mode.

Just like the Q7FN and NU8000, the Q7CN's input lag is depression fifty-fifty when interpolating lower frame rate games to 60 Hz or 120Hz using the game move interpolation feature chosen Game Motion Plus. When interpolating up to 60Hz (With the Judder slider set to 'ten' and the Blur slider at '0', input lag is 21.6 ms.

The Q7CN supports the new Automobile Low Latency Style which switches the TV automatically to Game Style when connected to a supported device (like the Xbox One or PS4) and a game is detected.

1080p @ 60 Hz @ 4:4:iv Yes

1080p @ 120 Hz Aye (native support)

1440p @ 60 Hz No

1440p @ 120 Hz Yes (native back up)

4k @ 60 Hz Yes

4k @ 60 Hz @ 4:iv:4 Yep

4k @ 120 Hz No

8k @ thirty Hz or 24 Hz No

8k @ 60 Hz No

The Q7CN supports most common resolutions with the exception of 1440p @ 60hz. Yet, information technology does support 1440p @120Hz just similar the rest of 2018 Samsung QLEDs.

Chroma 4:four:four for PC use is supported. Even so, it is necessary to enable HDMI UHD Colour from the External Device Manager for the port used and the input label must be set up to 'PC'. The Q7CN should automatically detect when a PC is connected and modify the label appropriately.

Merely similar the Q7FN all of the inputs for the Samsung Q7CN are on the separate One Connect box. On the side of the box are 3 USB 2.0 ports.

Dynamic Range Compression 3.49 dB

The frequency response of the Q7CN is decent. LFE (depression-frequency extension) is at 71Hz, which is higher up-average. This means the bass of this TV will have a decent about of body and punch to it, only 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, and then may not be loud enough for large and crowded places.

Weighted THD @ lxxx 0.639

Weighted THD @ Max ane.030

Other Smart Features Aye

Remote App Samsung SmartThings

This is the same remote as the ane plant with the Q7FN and the NU8000. It has just a few buttons, and you have to go through the home menu to attain your desired pick, or you lot can use Samsung's Bixby vocalisation banana feature. Bixby's vocalism recognition works very well. It can perform many TV commands like 'Modify to HDMI 1', 'Set backlight to xx', but it tin can also reply bones questions similar 'What'southward the weather condition like tomorrow', or help yous 'Pause the video'. You can also use the remote as a universal remote for other devices, even devices that don't support HDMI CEC, using Samsung'due south OneRemote characteristic.

In that location are v buttons under the center of the TV, identical to the Q7FN. They are laid out in the shape of a directional pad which can be used to quickly admission most settings.

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 dissimilar blazon of panel or if their Samsung Q7CN doesn't represent to our review, let us know and we will update the review. Notation that some tests such every bit gray uniformity may vary between individual units.

Size	US	Canada	Panel Type	Refresh Rate
55"	QN55Q7CNAFXZA	QN55Q7CNAFXZC	VA	120Hz
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 nosotros have reviewed earlier in the year. The ii TVs are almost identical in design and in operation.

Compared To Other TVs

Top left: Samsung Q6FN (QN55Q6FN ). Lesser left: Samsung Q7FN (QN55Q7FN). Eye: Samsung Q7CN (QN55Q7CN). Top right: LG SK9500 (65SK9500). Bottom correct: Sony X900F (XBR55X900F).  Dissimilar our other photographs, this picture wasn't taken nether a controlled surroundings, and then practice not draw conclusions from it.

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

55" 65" 75"

The Samsung Q7CN is somewhat amend than the Samsung Q8C. The Q7CN has better black uniformity that matters when you sentry dark scenes in a dark room. The Q7CN tin besides overcome the glare of a bright room amend since information technology tin can go 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.

49" 55" 65" 75" 85"

The Sony X900F is slightly improve than the 2018 Samsung Q7CN QLED Idiot box. The X900F has a much better nighttime 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 manner and FreeSync, which arrive a better option if you play a lot of games. Finally, the Q7CN can handle reflections slightly better.

55" 65" 75"

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

65"

The Samsung Q7CN is a fleck meliorate than the LG SK9500 unless you'll be watching from the side, in which case the LG is a meliorate 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 grayness uniformity and is better at treatment brilliant room reflections. Finally, the Samsung Q7CN is a amend pick for HDR gaming due to the lower input lag and back up for the FreeSync variable refresh rate.
