The Samsung Q9F is the brand's highest-end QLED LCD TV and offers excellent performance for mixed usage. In dark rooms, the high native contrast ratio and great local dimming result in deep dark scenes, and in bright rooms, the excellent anti-reflective coating and high peak brightness help to overcome glare. Unfortunately, when watching sports, some dirty screen effect is noticeable due to nonuniform areas of the screen and the image loses accuracy when viewed at an angle.

Note that this is a different TV to the 2017 QLED Q9F. The 2018 Q9FN is also called the Q9F or Q9.

Pros
  • Very bright in both SDR and HDR
  • Very low input lag, even with interpolation
  • Great motion handling
Cons
  • Image loses accuracy when viewed at an angle

Design

Score components: Subjectively assigned
Samsung Q9FN/Q9/Q9F QLED 2018 Design Picture
Curved : No

The design of the Samsung 2018 Q9FN QLED TV is excellent. It has a modern, simplistic design that will fit well in any decor. The One Connect box is bigger than last year's, but the cable now provides power as well, so when wall-mounted, the TV only has one very thin cable running to it that can be easily hidden. There are also two alternative stands available if you are looking for something more stylish.

Stand
Samsung Q9FN/Q9/Q9F QLED 2018 Stand Picture

The stand of the QN65Q9FNAFXZA is solid and well built. The design does not allow for a soundbar to be placed directly in front, but is designed for the One Connect box to fit neatly behind the TV. The TV is also compatible with replacement stands from Samsung if you are looking for something more stylish, like the Gravity Stand or the Studio Stand.

Footprint of the 65" TV stand: 18.7" x 14.4"

The One Connect box measures 15.4" x 5.2" x 2.6".

Back
Samsung Q9FN/Q9/Q9F QLED 2018 Back Picture
Wall Mount : VESA 400x400

The back of the TV is very simple. There is only the One Connect cable running into the back. There is some flex in the back panel but this shouldn't cause any issues. There is a removable panel to install one of the alternative stands or for the Samsung No Gap Wall Mount.

Borders

Borders : 0.43" (1.1 cm)

The borders of the TV are thin and look good. There is a small gap between the inside edge of the border and the panel.

Thickness
Samsung Q9FN/Q9/Q9F QLED 2018 Thickness Picture
Max Thickness : 1.61" (4.1 cm)

The Samsung Q9F is thin, it can sit flush with the wall when mounted. It is thinner than the Q8FN.

9.5 Build Quality
Samsung Q9FN/Q9/Q9F QLED 2018 Build quality picture

Excellent build quality. There is a lot of plastic, but the border and stand are metal. Like the Q8FN, there is some flex in the back panel but not enough for there to be any issues.

Picture Quality

Great picture quality on the 2018 Samsung Q9 QLED TV. It has an excellent contrast ratio and black uniformity, and the local dimming feature is very effective to improve dark scene performance. It is also one of the brightest TVs we have ever reviewed and has excellent reflection handling, making it a great versatile TV perfect for bright or dark room viewing. It has decent gray uniformity, but there is some dirty screen effect which is noticeable when watching sports. Like all VA panels, the viewing angle is narrow so the best seating is reserved for directly in-front. The Q9FN has a great wide color gamut, but color accuracy is not great out of the box.

9.2 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.

Excellent native contrast ratio, and the local dimming feature helps to create even deeper dark scenes.

As with all Samsung TVs that support local dimming, it is not possible to disable local dimming in the menus. We used the hidden service menu to disable it for our tests.

8.0 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

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.
:
Full-Array

Great local dimming on the 65" Q9FN. The algorithm is very aggressive at reducing blooming, which creates excellent deep blacks, but some detail may be lost in very dark scenes.

Here is a side-by-side with the Sony Z9D on the left, the Q9FN on the right. The local dimming on the Q9FN is very aggressive even when set to low, so small details in the stars are lost. Those who like the deepest dark scenes may prefer the local dimming algorithm of the Q9FN, but those who are weary about losing dark scene details will prefer less aggressive algorithms.

Excellent brightness for SDR content. While brightness in our real scene test is not as bright as the Sony X930E or Z9D, it is a significant improvement of the 2017 Q9. Small highlights in dim scenes are extremely bright as shown by our 2%, 10% and 25% windows. The Q9FN is an excellent choice even for very bright rooms as the whole screen can get bright as seen in the 100% white window.

Excellent peak brightness in HDR. The Samsung Q9F is one of the brightest TVs we have tested. The TV's local dimming is very effective at producing extremely bright small highlights in dark scenes as shown by the 2% and 10% window brightness.

The Z9D, X930E and X940E are brighter in our real scene test, but small highlights on test patterns are not as bright as the Q9FN.

With the 'Dynamic' picture mode displaying our 10% window, the Q9FN is able to briefly (<5s) spike the brightness as high as 3392 cd/m², the highest brightness level we have ever measured.

Decent gray uniformity of our QN65Q9FN. There is some dirty screen effect in the center which will be noticeable when watching anything with large areas of similar color, like hockey or football. The 5% test screen is much more uniform, which is good when watching dark scenes in sci-fi or horror movies.

The Samsung Q9F has a poor viewing angle, like other VA panels we've tested. Black levels shift significantly when viewed off angle, and the picture dims quite a bit. Colors shift when viewed off-axis, but the shift is not as noticeable. IPS-type LCD TVs like the SK9000 and OLED TVs like the C8 are superior in this regard.

Excellent black uniformity on the Samsung Q9FN 2018. There is very slight clouding around our test cross, but it shouldn't be noticeable and dark room viewing is excellent.

Note that the local dimming can't be disabled through the regular settings menu, so we disabled it through the service menu in order to evaluate the overall panel's native black uniformity.

What it is: The color temperature is a measure of the color of light. 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.

What it is: The best value for the TV's gamma setting; the setting name differs between TV brands.
When it matters: Shadows, accurate grayscale performance.
:

Out of the box color accuracy is poor. Greens and yellows especially are inaccurate. We took our readings with a 100% window, as the local dimming is very aggressive with our regular 18% window and cannot be disabled.

The overall color temperature is not too bad, and gamma is following a curve closer to 2.4 than our target 2.2.

Update 04/12/2019: This TV was incorrectly measured with Brightness +2, instead of at 0. This only has a small impact on the results (slightly dimmer dark scenes below about 30 IRE) and so we don't plan to retest it.

9.4 Post Calibration
What it is: TV's color accuracy after a full calibration with a spectrophotometer.
When it matters: All video on a TV that has been professionally calibrated. This isn't that useful, because most TVs can achieve a pretty good calibration if you spend enough time on them.

Samsung Q9FN/Q9/Q9F QLED 2018 EOTF

The Samsung Q9F has an excellent color gamut, covering almost all of the SDR color space. HDR coverage is very good, the Q9FN displays a wide color gamut, but it is unable to reproduce some of the new green tones in the Rec.2020 color space, very few TVs can. The performance is almost the same as the Q8FN, and we expect that the differences are due to small panel variances.

The Game Mode and PC Mode EOTFs also follow the input stimulus well, which is good.

Update 05/24/2018: HDTVTest has shown that for lower brightness HDR infoframes (such as 1000 nits) the TV produces scenes which are brighter than intended (see his video here). You can see more about this in the Additional review notes.

The Q9FN has great color volume. It is able to produce very bright and very dark colors, across its entire color gamut. It is much similar to the 2017 QLEDs, and much better than the LG C7, B7A and C8.

The color volume on the Q9FN is very similar to that of the Q8FN. The difference should not be noticeable and is likely due to unit variance.

Motion

The Samsung Q9FN has great motion handling. It has an excellent response time, and there is very little persistence trail. Like the Q8FN, the backlight has been improved over the 2017 QLEDs, and now flickers at an imperceptible 480 Hz in most modes. It also has an improved optional Black Frame Insertion feature, which can now flicker at 60 Hz in Game Mode to help games appear more fluid and can interpolate lower frame rate content up to 120 Hz, even in Game Mode.

The Samsung Q9FN has an excellent response time. The blur in the photo is due to persistence, there is almost no motion trail.

The response time results were obtained with the 'Standard' picture mode, because 'Movie' mode had a bug with our 20% gray slide (see our Additional Review Notes); however the TV's picture mode should not have any impact on response time.

7.9 Flicker-Free

Good value: 0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
:
480 Hz

The Samsung Q9 uses PWM to dim the backlight, and it flickers regardless of backlight setting. Similar to the Q8FN, the backlight flicker changes depending on settings. In 'Movie' mode it flickers at 480 Hz which should not be noticeable to most people and doesn't cause any motion duplication.

When in 'Game' or 'Standard' mode, or when 'Auto Motion Plus' is enabled, the backlight changes to a more noticeable 120 Hz flicker.

10 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.
When it matters: When flicker is desired by the user. Flicker is especially useful to make motion look clearer when viewing 60 fps content (sports, video games) and when using motion interpolation.

The Samsung Q9FN can interpolate lower frame rate content up to 120 Hz to help reduce stutter. This function is commonly known as the 'Soap Opera Effect'. Some people find the effect strange, and in scenes with lots of motion there are artifacts. When motion gets too intense the Q9FN, like all Samsung TVs, will stop interpolating, preferring accuracy.

Interpolation is activated by setting 'Auto Motion Plus' to 'Custom'. The 'Judder Reduction' can be adjusted for low frame rate content, and the 'Blur Reduction' slider can be adjusted to help clear up motion on 60 fps content. When interpolation is enabled, the backlight changes to a 120 Hz flicker as seen on the Q8FN here.

The Q9FN is nearly judder free. When playing 24p content through a 60i source, like from a cable box, the Q9FN was inconsistent in removing judder. In a 24 frame test, there is judder in only 2 of the frames. This probably won't be noticeable to most people. Like other Samsungs we have tested recently, this result is unexpected and we will retest this with future firmware updates.

The Samsung Q9F does not currently support a variable refresh rate. We tested with the Freesync 2 on the Xbox One S and with a PC with a Radeon RX 580 GPU.

Update 05/23/2018: Firmware version 1103 has added Freesync support. We are currently testing it and will update the review shortly.

Update 06/08/2018: FreeSync has been tested and the score has been updated. FreeSync was supported from our Xbox One S and our Radeon RX 580 GPU, in 1080p, 1440p and 4k resolutions. FreeSync is activated by enabling the TV's Game mode and FreeSync settings; PC mode is not required. We tested in Ultimate mode because it has the widest range, and we only recommend Basic mode when you experience problems with Ultimate.

1440p @ 120 Hz: 10.8 ms

Excellent low input lag on the 2018 Q9FN across all input resolutions, as long as Game Mode is activated. Excellent low input lag at 120Hz, which is great for gaming.

With Game Motion Plus enabled, input lag is 21.0 ms with 60 Hz interpolation, and 27.3 ms with 120 Hz interpolation.

Update 06/05/2018: Input lag of 1440p @ 120 Hz: 25.2 ms. This input lag was tested at the same time as the others, but was omitted from the review by mistake.

Update 06/11/2018: 1440p @ 120 Hz performance has improved as of firmware version 1103. The 1440p @ 120 Hz input lag is now 10.8 ms, down from 25.2 ms.

Update 01/07/2019: Firmware 1103 also added VRR support (see the VRR box), but we were unable to test the VRR input lag because the TV's backlight flicker caused problems with our input lag tool. We expect the Q9FN's VRR input lag to be very similar to that of the Q8FN, as all the other 2018 QLED models had similar VRR input lag.

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The sound quality of the Samsung Q9F 2018 is about average. This TV gets loud enough for most use cases and does produce well-balanced dialogs. However, it lacks a lot of bass, doesn't have a room correction system, and produces compression artifacts when put under maximum load. For a better sound, a dedicated sound system is recommended.

Dynamic Range Compression
What it is: The amount of difference between the TVs frequency response performance at 70dB SPL and Max dB SPL. Too much compression will result in pumping in the sound.
When it matters: When an accurate and free-of-pumping performance is required at higher volumes
Good value: < 3dB
Noticeable difference: 0.5
:
5.17 dB

The frequency response of the Samsung Q9FN is about average. Low-frequency extension (LEF) is at 113Hz, which is mediocre, especially since the LFE worsens as the TV is put under more load. This results in a bass that's lacking considerable amount of punch/kick, and has no thump/rumble. However, the response above the TV's LFE is quite well-balanced, but since it doesn't have a room correction system, it wasn't able to remove out test room's modes around 200Hz. Also, this TV gets loud-enough for most use cases too, but there will be pumping and compression artifacts present as the TV approaches its limits.

7.4 Distortion
What it is: Deformation of an output signal compared to its input, usually clipping, harmonic distortion, or inter-modulation distortion caused by non-linear behavior of the sound system.
When it matters: When a clean, pure and transparent reproduction is desired.

The Samsung Q9FN is a versatile TV that is excellent for a wide range of usages. It has some great features, but comes at a very high price. See some of our comparisons below for how it compares to other TVs on the market. See also our recommendations for the best smart TVs and the LED TVs.

Samsung Q8FN/Q8/Q8F QLED 2018
55" 65" 75" 82"

The Samsung Q9FN is slightly better than the Samsung Q8FN. The Q9FN has better dark room performance thanks to the better local dimming feature and better black uniformity. Overall performance is very similar between the two. The Samsung Q8FN does not use the One Connect box and all connections run to the back of the TV towards the side.

LG C8 OLED
55" 65" 77"

The LG C8 OLED TV is better than the Samsung Q9FN for most people, unless you watch a lot of static content and are concerned about burn-in. The LG C8 has an infinite contrast ratio and no need for a local dimming feature, as well as an ultra-wide viewing angle, but it can experience permanent burn-in. The C8 has a nearly instantaneous response time, although this can bother some people as 24p content can appear to stutter. The Samsung Q9FN has much better color volume and is much brighter and better capable of overcoming glare in a bright room.

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

The Samsung Q9FN is a bit better than the Sony X900F. The Q9FN has better dark room performance thanks to the better local dimming feature and better black uniformity. The Q9FN has better reflection handling and can flicker at 60Hz which is good for clearing up motion. The Samsung Q9FN has a few features geared towards gamers, including auto low latency mode and support for AMD's FreeSync 2. The Sony X900F has a faster pixel response time, so motion looks smoother and has less motion blur.

Sony Z9F
65" 75"

The Samsung QLED Q9FN is slightly better than the Sony Z9F overall. The Samsung Q9FN is much better in a dark room, thanks to the much better native contrast ratio and black uniformity. The Q9FN produces a wider color gamut, with better color volume. The Q9FN is better overall for gaming, as it supports FreeSync VRR and auto low latency mode. The Sony Z9F is brighter overall, but some small highlights can appear brighter in some scenes in HDR on the Q9FN.

Samsung Q9F/Q9 QLED 2017
65" 75"

The 2018 Samsung Q9FN is much better than the 2017 Samsung Q9F. The Q9FN has significantly improved dark room performance, thanks to the much better local dimming feature and much better black uniformity. The Q9FN is brighter with all types of content and has new features geared for gamers, including a variable refresh rate and auto game mode when used with a supported console or PC.

Samsung Q90/Q90R
65" 75" 82"
