Samsung Q7F vs LG OLED B7A (QN55Q7F vs OLED55B7A, QN65Q7F vs OLED65B7A)

by on December 10, 2017
 


Samsung Q7F is the lowest model of Samsung’s 2017 4K TV lineup while LG OLED B7A / B7 is the lowest model of LG’s 2017 4K OLED TV lineup. In the market, there are 3 screen sizes option available for Q7F those are 55 Inch (QN55Q7F), 65 Inch (QN65Q7F), and 75 Inch (QN75Q7F), while for OLED B7A, there are only 2 screen sizes option available including 55 Inch (OLED55B7A) and 65 Inch (OLED65B7A). Since the screen sizes available on both are 55 Inch and 65 inch, this comparison certainly is also as true to 55 inch (QN55Q7F vs OLED55B7A) and 65 Inch (QN65Q7F vs OLED65B7A). When I was writing this comparison, for 55 Inch, they are sold with similar price, while for 65 inch, OLED65B7A is sold hundreds dollar more expensive than QN65Q7F. But of course, these prices are certainly are not fixed and still could change at any time. So, which superior between them and which is a better choice between them?

Short Review of Samsung Q7F (QN55Q7F, QN65Q7F, QN75Q7F)

Samsung Q7F Review

As we have mentioned, Samsung Q7Fis the lowest model of Samsung’s 2016 QLED TV lineup. As a part of QLED TV lineup, the Samsung’s advanced quantum dot panel becomes its mainstay, makes it offers outstanding color reproduction. Nevertheless, this certainly is not just its rendition of colors that is strong, but also other aspects of picture quality are also strong, make the picture displayed on the screen of Q7F looks really amazing.

On its panel, Samsung Q7F uses VA panel with edge lit backlight and local dimming technology named “Precision Black Pro”. Supported by other technologies like Supreme UHD Dimming, Q Elite Black, Ultra Black, and others, this makes Q7F has strong native contrast ratio and deep black level, makes its dark room performance is excellent. Otherwise, for delivering bright peak luminance that makes its bright room performance and HDR performance is great, Q7F is also powered by some Samsung’s advanced technology like Peak Illuminator Pro, Ultra Clear Panel, and others. This makes its peak brightness  is fairly bright to dampen the glare of ambient light, makes its picture quality still looks amazing even if when set in a very bright room. Meanwhile, coming with HDR technology, Q7F is powered by Q Engine as its picture processor and Q 4K HDR elite as its HDR processor, make it is able to produce sharp and clear HDR image.  But unfortunately, unlike its competitor like B7A or Sony X930E that already support most of HDR formats, Samsung Q7F supports HDR 10 and HLG (Hybrid Log Gamma) only. With all of these technologies that support it, overall, picture quality and HDR performance of Q7F is excellent for its class.

For delivering smooth and clear picture quality when used to play 24p movies or video contents with fast moving scenes, Q7F is powered by Motion Rate 240 Hz technology based on native 120 Hz refresh rate panel. Additionally, since it has native 120 Hz refresh rate panel, this certainly also make it is able to interpolate both lower frame rate contents 30 fps and 60 fps. Q7F is also a good TV when used for playing any kind of games, even for fast games due its input lags at any source in “Game Mode” is quite low. And to offer simple, responsive, and attractive smart experience in your home, it featuring Tizen OS as its smart TV platform that powered by a fast quad core processor and decent memory capacity.

Short Review of LG OLED B7A (OLED55B7A, OLED65B7A)

LG OLED B7A Review

LG OLED B7A is also the lowest model of LG’s 2017 4K OLED TV lineup. Although it is sold hundreds even thousands dollar cheaper than the series above like C7, E7, G7, even W7, but performance and picture quality offered is not far behind them. As a TV that use OLED panel technology, infinite contrast and perfect black level certainly become the main strength of picture quality produced by OLED B7A, makes it offers excellent performance when used in a dark room. Nevertheless, although the other aspects like color performance, peak luminance and other are not the best, but what offered by OLED B7 are strong, makes the picture displayed on their screen looks really amazing, no matter the light condition of a room where it is used, no matter viewed from the front and center or an angle.

Meanwhile, for maximizing its rendition of colors, LG OLED B7A uses 4 sub-pixels technology where there is white sub-pixel as the addition of the standard sub-pixels (RGB). Powered by Tru Color Accuracy and Cinematic color technology, this makes OLED B7A has great rendition of colors with excellent wide color gamut and only a bit worse than SJ9500 or Samsung QLED TV with the best color gamut. For maximizing its peak luminance so it can maintain their amazing picture quality in a bright room, LG OLED B7A is powered by Ultra Luminance technology. Additionally, its peak luminance is also quite bright to show highlight of HDR images so looks excellently, even its peak brightness is brighter than 550 nits as the minimum recommendation to get Ultra HD Premium Certification set By UHD Alliance for OLED TV. Talking about HDR, LG OLED B7A is powered by Active HDR engine as its HDR processor. Not just HDR 10 and HLG that are supported by OLED B7A, but it also already support Dolby Vision by Dolby Laboratories and Advanced HDR by Technicolor. This certainly allows you to enjoy more HDR formats with each of their own advantages. Even not just that, LG OLED B7A also has a feature named “HDR Effect” that has the ability to improve the color and brightness range of the picture. Combined to its great performance of its 4K Up-scaling engine named Tru 4K Up-Scaler, this allows you to enjoy any content with the quality as close as possible to 4K HDR.

In addition to excellent picture quality and wide viewing angle coverage, LG OLED B7 also has excellent performance when playing fast moving images and 24p videos. This allows you to enjoy your favorite sports or movies with smooth and clear picture quality. Additionally, although not as low as SJ9500 or SJ8500 series, LG OLED B7 also has excellent input lags at any source in “Game Mode”, allow you to play any games responsively without laggy, even for fast paced games which require fast reflexes. And as its smart TV platform, it comes with the excellent the excellent WebOS 3.5, allow you to enjoy smart TV experience comfortably and easily.

Samsung Q7F vs LG OLED B7A Performance

Picture Quality

Essentially, both of Samsung Q7F and LG OLED B7 have excellent picture quality. In a dark room, both of them equally show excellent performance. Nevertheless, since OLED B7A has infinite native contrast ratio and perfect black level, this certainly makes its performance in a dark room is also more excellent than Q7F. Black looks really black and combined to its excellent black uniformity, indirectly, this certainly also makes darker color can be shown fairly accurate, makes dark scene of SDR images or even shadow details of HDR images looks excellent. Meanwhile, although not as perfect as OLED B7A, performance of Samsung Q7F in a dark room is also fairly good. With about 4700:1 of native contrast ratio, Q7F can reach about 0.021 nits of black level that means it is quite dark to makes dark scene looks excellent when set in a dark room. But unfortunately, its local dimming doesn’t work effectively to boost the contrast. This means, when the setting of local diming is maximized, there is no significant improvement on its contrast. Nevertheless, its black level is also quite dark to reveal details of images in dark scene of HDR images like the intended.  As the note, to show shadow details of HDR images, particularly HDR 10 images like what intended by UHD Alliance, an HDR TV must have 0.05 nits of black level or darker, while what reached by Q7F is far darker than this recommendation that means it is very good.

Meanwhile, when set in a bright environment, both of Samsung Q7F and LG OLED B7A also equally have good peak brightness that able to dampen the glare, makes the picture displayed on their screen looks consistently well. But even so, for a very bright room with a lot of light or sunny window, both of them are the best since there are brighter TVs like Sony X930E or Samsung Q7F that can fight the glare better. Meanwhile, compare between them, Samsung Q7F might be able to reach brighter peak brightness in small area of windows than OLED B7, no matter they are playing SDR or HDR images. This is due the local dimming of Q7F is very effective to brightens the small area. This certainly makes highlights of images in dark scene displayed on the screen of Q7F looks brighter than OLED B7. Otherwise, when displaying bright scene, the picture displayed on the screen of OLED B7 looks brighter than Q7F since it can reach brighter peak brightness in large windows sizes. Meanwhile, both of them are also equally able to show highlight of HDR images like what recommended by UHD alliance as the developer of HDR 10 format. As we know, UHD alliance has set different standardization for OLED TV and LED TV about the minimum peak brightness that must be reached by them to show HDR 10 images fully like what intended. For this case, the minimum standardization of OLED TV is 550 nits while LED TV is 1000 nits. With about 800 nits for OLED B7A and 1100 nits for Q7F, what reached by them certainly is brighter than the minimum recommendation that means both of them can show highlight of HDR images like the intended.

Discussing about their color reproduction, both of them equally have excellent rendition of colors. Their color performance is including the best in 2017. Almost all colors of HDR images in DCI P3 can be shown by them almost perfectly, makes the picture displayed on their screen looks fairly accurate. Additionally, most of colors in Rec.2020 also can be covered fairly well. Meanwhile compare between them, Samsung Q7F with quantum dot panel have a bit wider color gamut, makes it can properly show more colors than OLED B7A. Of course, this certainly also makes color of the picture displayed its screen also looks a bit more accurate than OLED B7, particularly when displaying HDR images which require wide color gamut. Additionally, Samsung Q7F also has better color volume than LG OLED B7A. Actually, OLED B7A is able to show its wide color gamut at extremely dark colors excellently, but unfortunately, colors in nearly its peak luminance cannot be shown fairly saturated due its RGBW sub-pixel structure. On other hand, Q7F is able to show its wide color gamut at its brightness range fairly well. But since its black level is not as deep as OLED B7, darker colors, particularly for extremely darker colors cannot be shown as saturated as OLED B7. While about color gamut and color volume, Samsung Q7F has better performance, OLED B7 can display a bit better color gradient than Q7F.  But overall, their color gradient is really great. Both of them might still have some imperfections in darker colors and the darker colors cannot be shown as smooth as brighter colors, but this issue is not as noticeable as visible on TV with 8 bit panel.   Nevertheless, although they still have some color banding in darker colors, but overall, for watching movies, this should not be a serious issue.

Meanwhile, talking about their side viewing angle, LG OLED B7A offers far wider viewing angle coverage than Samsung Q7F. Since it uses VA panel, the side viewing angle coverage of Q7F is poor. This means, when viewed from an angle, especially started 20 degrees off center and front or wider, the picture displayed on the screen of Q7F doesn’t look as good as when viewed from the center and front. On the other, OLED B7A has excellent side viewing angle coverage, even it is far better than LED TV with IPS panel. This means, it can fairly well maintain good picture displayed on its screen from any angle. With other words, no matter the angle of you are watching from, the picture displayed on the screen of OLED B7 will looks consistent. This certainly makes OLED B7A as a good choice for you who have a plan to use it in a wide room with viewers watch TV from multiple angles.

For anticipating the many non-4K contents which available in the market, both of Samsung Q7F and LG OLED B7 are equipped with great performance UHD Up-scaling engine. This allows you to enjoy any contents with the quality as sharp as resolution. Even when the source is low resolution content like DVD movies with 480p resolution, the final image in 4K that resulted still looks sharp and clear. And of course, the higher resolution of the source, like 720p videos or 1080p videos, the final images in 4K displayed on their screen will look sharper and clearer with small details are preserved better. For OLED B7, its ability even is not just that. With a feature named “HDR Effect”, once it is enabled, the brightness range and color of the picture will be improved as close as possible to 4K HDR quality, allows you to enjoy any content with the quality close to 4K HDR.

Samsung Q7F might have better renditions of colors than LG OLED B7, makes the color displayed on its screen looks more accurate than OLED B7A. But overall, since most of picture quality aspects of OLED B7 are better than Q7F, this certainly also makes its picture quality is better than Q7F.

Winner: OLED B7A

Motion Handling and 24p Playback

The other perfect performance that offered by OLED Panel as the panel technology of LG OLED B7A is about its extremely low pixel response time. This makes OLED B7A does an excellent job in handling motion blur when it is playing fast moving images like sports, fast games, or fast movies. The result, the picture displayed on its screen looks very smooth and clear. There is only an extremely short motion blur following fast moving object where most of people might not notice about it. Meanwhile, although not as excellent as OLED B7, Samsung Q7F also do a great job when handling motion blur, even including the best for LED TV. Its pixel response time is also very low for LED TV and combined to Motion Rate 240 that support it, this makes the picture displayed on its screen also looks smooth and clear. Following fast moving object, motion blur might be still slight visible, but it is only a short trail where this should not be a serious issue and most of people might also not notice about it. Meanwhile, when playing 24p contents, both Samsung Q7F and LG OLED B7A also equally do a great job. No matter the source of the movies, whether it is native 24p videos like Blu-ray movies, 24p videos via 60i signals like movies from Satellite TV, or even 24p movies via 60p signals like movies from Streaming Device, all of them will be shown clearly and smoothly with judder-free on each of their screen. To remove judder without adding “soap opera effect”, on Q7F, you just need set “Auto Motion Plus” to “Custom” and set both ”Judder Reduction” and “Blur Reduction” to “0”, while on OLED B7A, you just need to turn on the “Real Cinema”, set the “Tru Motion” to “User”, and set both “De Blur” and “De-Judder” to “0”. And since both of them have native 120 Hz refresh rate panel, this certainly make they are able to interpolate both lower frame rate contents 30 fps and 60 fps fairly well.

Winner: OLED B7A

Inputs/outputs

One Connect Box QLED

As their major inputs/outputs, both LG OLED B7A and Samsung Q7F equally equipped with 4 HDMI ports ver.2.0 support HDCP 2.2. Additionally, both of them are also equally equipped with 3 USB Ports, 1 RF IN (Antenna In), 1 Ethernet Port and 1 Digital Audio Out (Optical). Both of them are also not equipped with Component In. A bit difference between them is about Composite In (AV In) where OLED B7A is equipped with 1 Composite In (AV In), while Q7F is not equipped with this input. The other difference between them is about where their inputs/outputs are located. On OLED B7A, all of its inputs/outputs are located on its back or side panel, while on Q7F, most of its inputs/outputs are located on separated box named “One Connect Box ”. This gives you a benefit if there is an update of its ports in future, so you just need replace the box without change the TV. Meanwhile, about their input lags, essentially, both of them have low inputs lags at any source in “PC mode” and “Game Mode”. With about 20ms -25 ms of input lags, this allows you to play any kind of games responsively and without laggy on both, even for fast paced games that require fast reflexes. Compare between them, OLED B7 might have about 0.03 ms lower than Q7F, but this is not too significant to make playing games on both feels differently.

Winner: OLED B7A

Smart TV

Tizen OS vs WebOS

As their smart TV platform, both LG OLED B7A and Samsung Q7F are equally featuring simple, attractive, and responsive smart TV platform. For this case, Q7F comes with Tizen OS 2017 while OLED B7A comes with WebOS 3.5. In their 2017 version, Tizen OS comes with white theme and nicer animation that makes its appearance is more attractive than last year version, while for WebOS 3.5, it is supported by a new chip that makes its performance is more responsive and faster than previous version. But essentially, both of this OS equally offer simple, attractive and responsive smart TV experience with many smart features. On the home screen of Tizen, there is a ribbon across the bottom of the screen contain quick access to favorites and popular apps. Meanwhile, on the home screen of WebOS, there is also a “strip bar” across the bottom of the screen contain quick access to popular apps. This allows you to launch your favorite app without leaving the home screen. Additionally, both of these smart TV platforms are also provided a lot of attractive and useful preinstalled apps. There are VOD Service like Netflix, Amazon Videos, YouTube, and many more, Live TV, Web browser, Cloud Games, and many more. They also equally have apps store which provide tons of attractive downloadable apps. For this case, Tizen comes with Samsung Apps Store while WebOS comes with LG’s apps store. Nevertheless, in this case, apps provided by Samsung apps Store are more complete and diverse than what provided by LG’s apps store.

 

LG Remote vs Samsung remote

Meanwhile, as their controller, Samsung Q7F comes with smart remote named “Samsung Smart Controller”, while LG OLED B7 comes with the excellent “LG Magic Remote”.  Samsung remote only has few buttons and there are even no “number buttons” and not many “quick access button”. But even so, it has excellent voice command that allows you to control some TV function and smart features with your voice. It is made of metal and very well designed, makes it looks elegant in your hand. Additionally, Samsung’s remote also has a universal ability that means it can be used to control other devices connected on Q7F via HDMI ports. On the other hand, LG’s magic remote has more buttons than Samsung Remote and there are even two dedicated buttons as the quick access to Amazon Videos and Netflix, allow you to launch them without entering the WebOS. This remote is also equipped with built in remote for voice navigation. But unlike on Samsung TV that can control many features, the voice command of LG Remote is only limited to be used to search in the internet or search the contents and also control some other features. Like Samsung TV, this remote also has universal ability. The standout feature that offered is about “point and click” feature. In addition to there is a “scroll wheel” on the center on the remote to scrolling the highlight and click to open the app, the cursor on the screen also can follow the movement of the remote. This is like what offered by the remote of WII Nintendo and of course this will make navigation or browsing in the internet feel far easier.

Conclusion

As we have discussed a lot above, both of them equally have excellent picture quality and great HDR performance. LG OLED B7 is superior on contrast and black level while Samsung Q7F is superior on color reproduction. They are even equally certified by Ultra HD Premium Certification by UHD alliance that means they are able to show HDR images fully like what intended, especially for HDR 10 videos. Meanwhile, the excepting of side viewing angle, although technically OLED B7 is superior to Q7F, but with the limitations of the human eye, this makes the superiority of OLED B7 is not too significant. Their difference that is very noticeable is about their side viewing angle coverage, where it is only noticeable where the picture displayed on their screen is viewed from an angle.

Which is a better choice between them? As we have mentioned at above, for 55 Inch, OLED B7 and Q7F are sold with almost the same price, while for 65 inch, OLED B7A is sold hundreds dollar more expensive than Q7F. But once again, their prices certainly are not fixed and could still change at any time. Now, the decision comes back to you according to your need and taste. If you are searching 55 Inch TV, I think OLED55B7A is a better choice due it has many advantages but sold with almost the same price. But even so, if you prefer to choose QN55Q7F, this is also not a bad choice considering performance and picture quality offered also great for its class. On the other hand, if you are searching 65 Inch TV, keep in mind, OLED65B7A is sold hundreds dollar more expensive than QN65Q7F and the decision certainly is also depending on your budget.
