The Sony A9F is an outstanding OLED TV, one of the best we have ever tested. Like all OLEDs, it delivers perfectly deep blacks, and has wide viewing angles. HDR looks great thanks to the excellent wide color gamut, and the best color volume that we've measured so far on an OLED. It has excellent motion handling, low input lag, and all four HDMI ports support HDMI 2.0 full bandwidth. Unfortunately, it isn't very bright with bright white scenes. The Android 8.0 smart platform is much faster than previous Sony TVs.

Our Verdict

8.6 Mixed Usage

The Sony XBR-55A9F is an excellent TV that can handle just about anything. It is an outstanding TV for watching movies or gaming in a dark room. It has excellent motion handling and low input lag, great for fast paced content or gaming. Like all OLED TVs, there is a risk of temporary image retention and even permanent burn-in, although we don't expect this to be an issue for most people.

Pros
  • Excellent dark room performance
  • Near-instantaneous response time
  • Image remains accurate when viewed at an angle
Cons
  • Could experience permanent burn-in (see here)
  • Brightness is limited in white scenes.
9.4 Movies

The A9F is outstanding for watching movies in a dark room. The OLED panel delivers a perfect dark room viewing experience, and the image looks great, even if you are viewing from the side. It has a near instantaneous response time, which may bother some people as 24p content stutters. It is also free from 24p judder.

8.1 TV Shows

The A9F is a great choice for watching TV shows during the day. The wide viewing angles make it a perfect choice for someone that likes to move about with the TV on. It has excellent reflection handling, but might not be quite bright enough to overcome glare if you have a lot of windows. If you're a fan of the soap opera effect, the 120 Hz motion interpolation is a great option.

8.5 Sports

The Sony A9F is great for sports fans. It has excellent gray uniformity with very little dirty screen effect. Fast moving objects appear clear, with very little motion blur thanks to the near-instantaneous response time. It has wide viewing angles and good peak brightness, good for watching the big game with a large group of friends.

8.2 Video Games

Excellent TV for playing video games. It has excellent low input lag and supports all common resolutions. Fast moving objects are crisp and clear, and it has an optional black frame insertion feature to further improve motion. It has excellent dark room performance, great for late night gaming. Unfortunately, the A9F does not support any variable refresh rate technologies, like FreeSync, and there is a risk of permanent burn-in.

8.9 HDR Movies

The Sony A9F delivers a truly remarkable HDR movie experience. The infinite blacks deliver a perfect dark room experience, and the wide color gamut and very good color volume deliver outstanding picture quality. Unfortunately, it has only decent brightness in HDR, so some really bright scenes clip, and pure white scenes aren't very bright.

8.1 HDR Gaming

The A9F is an excellent TV for playing games in HDR. The OLED panel is perfect for playing in a dark room, as it delivers true blacks and perfect black uniformity. It has excellent low input lag and a near-instantaneous response time. It has decent brightness in HDR, but large white scenes aren't very bright. There is also a risk of temporary image retention and permanent burn-in.

8.2 PC Monitor

The XBR55A9F is a very good TV for use as a PC monitor. The wide viewing angles ensure an accurate image, even when sitting up close. It supports all common resolutions, and chroma 4:4:4 is displayed perfectly. Unfortunately, there is a risk of permanent burn-in when displaying static content, like menu bars, for long periods of time.

Curved No

The A9F has an outstanding design. It looks great, and is built with premium materials and an impressive attention to detail. The TV has excellent cable management, providing for an extremely clean look. Like the A1E, there are small rubber feet under the screen, so the screen itself is not resting on the table beneath it, and the screen tilts back slightly. Unfortunately, the design makes the A9F difficult to move, but most people are not going to be moving the TV often, so this shouldn't be an issue. 

Design
Stand

The stand design of the A9F is very similar to the Sony A1E. The stand is large and quite bulky, but supports the TV extremely well. Like the A1E, the stand causes the TV to lean back at a slight angle. The stand cannot be removed, as it contains the majority of the TV's electronic components.

There are two sets of feet underneath the screen portion of the A9F. The inner set of feet are larger, and appear to play a larger role in supported the TV. These feet require a surface at least 12.8" (32.5 cm) wide.

Footprint of the 55" stand: 11.5" x 48.3"

Design
Back
Wall Mount VESA 400x200

The back of the A9F looks extremely clean with the covers on, and has excellent cable management. The back panels have a fabric cover on them, similar to speaker panels.

Design
Borders
Borders 0.35" (0.9 cm)

The borders of the A9F are very thin. There is no noticeable gap between the border and the first row of pixels.

Design
Thickness
Max Thickness 3.62" (9.2 cm)

The display itself is quite thin, but the stand behind it is large. The stand can be folded in when wall mounted. The display portion of the screen is almost twice as thick as the LG OLED TVs, but still very thin.

The thickness measurement was taken with the stand folded in, as if the TV was wall mounted.

Good peak brightness in SDR on the A9F. Overall, it is similar to the A8F. Large white scenes aren't very bright due to the TV's ABL. When Peak Luminance is set to 'Off', the A9F displays at a constant luminance of ~140 cd/m², regardless of content. In any mode, the TV automatically dims after about 2 minutes of displaying static content, and this can't be disabled.

Update 10/03/2018: Retested the brightness after firmware PKG6.0348.0059NAA. All measurements are essentially the same as before (+/- 15 cd/m²). Notably the TV's aggressive dimming over time is unchanged; sometimes the TV dims after just two minutes of static content, as shown in the plot over time. The measurements in the review have not been changed.

Update 02/27/2018: Retested the brightness using a PC as the source, so we can automate testing; previously we were using a Samsung K8500 Blu-ray player as the source, but we found that it was sending a brighter signal than a PC (perhaps by sending 'brighter than white' stimuli). The A9F was retested with the PC as the source, and treated this signal differently, causing its measured brightness to be ~50 cd/m² less; however, we consider this to be more accurate to most sources. The test scores have been updated.

Decent peak brightness in HDR. Small highlights in some scenes get bright enough to stand out, but bright white scenes are dim. Overall, the A9F's HDR brightness is slightly worse than the A8F, as some small details in some scenes aren't as bright.

If you find HDR content too dim, you can adjust the Contrast and Gamma to your liking. If it is still too dim, increase the Adv. Contrast Enhancer setting to your liking.

Update 10/03/2018: Retested the brightness after firmware PKG6.0348.0059NAA. All measurements are essentially the same as before (+/- 15 cd/m²). Notably the TV's aggressive dimming over time is unchanged; sometimes the TV dims after only one minute of static content, as shown in the plot over time. The measurements in the review have not been changed.

The Sony A9F has excellent gray uniformity, similar to the LG C8 and Sony A8F. There is very little dirty screen effect, and there shouldn't be any issues watching sports. In dark scenes, as measured with the 5% gray, there are some noticeable vertical bands. This is commonly seen on OLED TVs but shouldn't cause any issues.

Good color and white balance out of the box. Like most Sony TVs, the most accurate Picture Mode out of the box is 'Custom'. The color temperature is a bit on the warm side, but this likely isn't noticeable by most people. Sony 'MASTER' TVs, including the A9F and Z9F, appear to target a different gamma to the 2.2 standard. This is strange, because previous models followed our target of 2.2 accurately in the 'Custom' picture mode.

Update 02/27/2019: Retested with the 'Gamma' setting set to '0', rather than '2' as it is by default, so the TV better tracks the 2.2 target gamma; the score has increased as a result. All test scores and pictures have been updated.

The A9F has an excellent wide color gamut; slightly better than the A1E and nearly identical to the A8F. The EOTF follows the input stimulus perfectly, but clips at the TV's peak brightness. The 'Game' and 'Graphics' EOTFs are nearly identical to the 'Custom' EOTF, which is great.

If you find HDR content too dim, you can adjust the Gamma, Contrast and Adv. contrast enhancer, all of which make the TV brighter. With everything at maximum, HDR content will be noticeably brighter.

Unlike previous Sony TVs, all picture modes on the A9F and Z9F follow the same EOTF. On older models, some picture modes would have a smoother roll off at the TV's peak brightness, so there would be less clipping.

There is very slight image retention on the A9F. These results are better than all other OLED TVs we've reviewed so far, with the exception of the LG B8. Note that there is some variation in temporary image retention performance, even between units of the same model so this difference may just be panel variance.

This test is only indicative of short term image retention and not the permanent burn-in that may occur with prolonged exposure to static images. We are currently running a test to help us better understand permanent burn-in. You can read about our investigation into this here.

Update 11/01/2019: Updated text to include our stance on burn-in.

Although we don't expect most people who watch varied content to have any issues, OLED TVs, such as the Sony A9F do have the possibility of experiencing burn in. There is a pixel-shift option on the A9F that will shift the entire screen by a few pixels (this is not very noticeable) to help reduce the risk of burn-in.

The A9F can insert black frames to simulate flicker, which can help motion appear clearer. It only supports 60 Hz flicker, which can bother some people.

Unlike the LG C8, when 24p content is displayed on the A9F with BFI enabled, the BFI frequency changes to 48 Hz.

BFI is enabled on the A9F by setting Motionflow to 'Custom', Smoothness to 'Min', and Clearness to 'High'.

The A9F can interpolate content to match the panel's native 120 Hz refresh rate. Like most TVs, this will introduce some motion artifacts, and in scenes of heavy action the TV will sometimes stop interpolating.

To enable motion interpolation on the A9F, set Motionflow to 'Custom', and increase the Smoothness slider. For 30 fps content, you must also set CineMotion to 'Auto'.

The Sony A9F supports Dolby Vision, but external devices must be updated to support it. Like the Z9F, in our tests Dolby Vision worked on an Apple TV, but not from a Chromecast 4k. Like the Z9F, the A9F has four full bandwidth HDMI 2.0 ports, which is new for Sony TVs.

The A9F supports eARC and HDCP 2.3, but unfortunately we have no way to test this at this moment, and very few devices are able to take advantage of these new technologies.

Update 02/27/2019: eARC has now been tested, and is properly supported; see the Audio Passthrough box.

The frequency response of the A9F is good. LFE (low-frequency extension) is at 67Hz, which is good for a TV. This means this TV has a decent amount of punch to its bass. However, it still lacks sub-bass, so it won't produce any thump or rumble. The response above the LFE point is quite well-balanced, which is important for the reproduction of clear and intelligible dialog. Also, this TV gets quite loud, but produces noticeable pumping and compression artifacts under heavy loads. The older A1E has a very similar performance, but it measured slightly better than the A9F in our test room.

The distortion performance of the A9F is mediocre. The amount of THD produced at 80dB SPL is quite low in the bass and mid ranges, but quite elevated in the treble range. This make the sound of the treble range a little impure, but this won't be very noticeable in real-life situations. At Max SPL, this TV, like most other Sony TVs, shows an significant rise in THD, but again, this will probably be only noticeable with test signals. The older A1E doesn't have the elevated treble THD at 80dB SPL, but its Max SPL THD is quite similar.

The Android 8.0 interface is well organized and easy to navigate. The general layout is a significant improvement over previous Sony models. Some common apps, like the settings menu, are now easier to access as they have been moved to the top of the page.

While the main interface has been updated, the settings menu hasn't. Some settings are difficult to find and it takes some getting used to.

Update 06/10/2019: Google has pushed an update to some Sony TVs that run the Android Oreo update. This update adds a row of Google Sponsored Content in the second row of the home page. Unlike the existing sponsored content, this row cannot be removed normally from the Customize Channels menu. There is a workaround though, which is available here.

There is suggested content in the home menu, but it can be disabled by removing the channel.

The A9F has the same remote control as the Z9F. It has a rubberized back, and soft touch buttons. There are a lot of buttons, more than most remotes from other brands. There is also a quick access button for Netflix, the Google Play Store, and Google Assistant voice control. Most of the remote functions require direct line-of-sight to the TV.

The A9F has a similar control scheme to the other 2018 Sony TVs like the Z9F and X900F. It allows quick access to change channels, inputs, and adjust the volume, as well as powering the TV on or off.

Differences Between Sizes And Variants

We tested the 55" Sony MASTER Series A9F (XBR55A9F), and for the most part, we expect our review to be valid for the 65" model (XBR65A9F) as well.

The European variant of the TV is also known as the AF9, and we expect it to offer the same performance.

If someone comes across a different type of panel or if their Sony A9F doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Compared To Other TVs

Comparison picture

Top left: Sony Z9F(XBR65Z9F). Bottom left: Vizio P Series Quantum (PQ65-F1). Middle: Sony A9F (XBR55A9F). Top right: Sony Z9D (XBR65Z9D). Bottom right: Sony A8F (XBR55A8F).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Sony A9F is an excellent OLED TV, but it faces steep competition from LG and Samsung in the top-end TV market. See our recommendations for the best televisions and the best flatscreen TVs.

Sony A9G OLED
55" 65" 77"

The Sony A9F and the Sony A9G have very similar performance. They have a very different design and different remote control. It's hard to notice any differences in performance when watching normal content.

Sony A1E OLED
55" 65" 77"

The Sony A9F is slightly better than the Sony A1E. The A9F has slightly better picture quality, thanks to higher peak brightness and better color volume. The A9F has much better input lag with a 1080p source, and all four HDMI ports support the full bandwidth of HDMI 2.0. The A9F also has a faster smart interface thanks to a newer version of Android TV OS and a newer chipset.

LG C8 OLED
55" 65" 77"

There are only minor differences between the LG C8 and the Sony A9F. The C8 is a bit brighter than the A9F, but the C8 has worse color volume. We don't know if this is a result of variance between panels. The C8 runs LG's WebOS smart interface, whereas the A9F runs Android TV OS. Both are great, but they have vastly different interfaces and some people may prefer one over the other.

Sony A8F OLED
55" 65"

The Sony A9F is slightly better than the Sony A8F. Both TVs have excellent dark room performance thanks to the OLED panel which can produce perfectly deep blacks. The A9F has better color volume and displays gradients better. The A9F also has lower input lag, native support for 1080p @ 120Hz, great for Xbox One S/X owners, and all four ports on the A9F support HDMI 2.0 full bandwidth. The A9F also has faster smart features, thanks to a newer version of Android TV OS, and a newer chipset.

LG C9 OLED
55" 65" 77"

The Sony A9F OLED and the LG C9 are both OLED TVs, and they perform almost identically. The LG C9 is a bit brighter and has slightly less input lag. Although the Sony A9F supports eARC, the LG C9 supports the extra bandwidth of HDMI 2.1 on all four HDMI inputs. Although this doesn't add anything at the moment, once there are HDMI 2.1 sources on the market, this should allow the C9 to accept a 4k @ 120Hz signal, even with a 10 bit, full chroma signal.

LG E9 OLED
55" 65"

The LG E9 OLED and the Sony A9F OLED have very similar performance. The E9 is a little brighter and has a lower input lag. The LG E9 is advertised as supporting HDMI 2.1 on all four HDMI inputs. and although this doesn't add anything at the moment it makes the TV more future-proof.

LG B8 OLED
55" 65"

The Sony A9F OLED is marginally better than the LG B8. When in HDR, the Sony A9F has marginally better color volume, and its ABL is a little less distracting. Also, the Sony A9F has slightly better gray uniformity, which might be more apparent in sports. The LG B8 has a lower input lag, which is great for gamers and slightly better performance as a PC monitor.

Samsung Q9FN/Q9/Q9F QLED 2018
65" 75"

The Sony A9F is better for dark or wide rooms than the Samsung 2018 Q9FN, unless the possibility of temporary image retention or permanent burn-in is a concern. The Samsung Q9FN is much brighter which helps it to overcome glare, but it has worse uniformity and bad viewing angles. The Q9FN has lower input lag and supports FreeSync VRR, great for gaming. The A9F has better dark room performance, thanks to the OLED panel that delivers true blacks and perfect black uniformity.

LG E8 OLED
55" 65"

The Sony A9F and the LG E8 both have very similar performance. The Sony A9F has better color volume for which is great if you watch a lot of HDR content. The A9F also has better gray uniformity which is great is you watch sports, and it supports a 1440p resolution for those who play video games. On the other hand, the LG E8 has a lower input lag which makes it very responsive to your actions.
