The Samsung Q7F QLED TV is a good, well-rounded 4k TV that will perform well in almost every use-case. It's not the brightest in its category, but the Samsung Q7 produces better colors than any other TV. Motion is excellent as well, and its input lag is among the best available.

Pros
  • Large color volume
  • Motion handling is excellent
  • Low input lag for gamers
Cons
  • Image degrades at an angle

Samsung Q7F Design Picture
Curved : No

The design of the Samsung Q7F QLED TV is an improvement over the 2016 models such as the KS8000. It looks great, with thin borders and a sleek stand. The OneConnect box is bulkier than last year, and the need for two power points (one for the TV and one for the OneConnect box) is a questionable design choice, but required since the only cable between the OneConnect and TV is optical.

Stand
Samsung Q7F Stand Picture

The central stand feels very secure and supports the TV well. The flat design of it looks better than Samsung's 2016 models such as the KS9000.

There is an option for two alternative stand designs, the 'gravity stand' and the 'easel stand'.

Note that it is possible to route the cables through the stand, as visible here.

Footprint of the 55" TV stand: 11.2" x 33.5"

Back
Samsung Q7F Back Picture
Wall Mount : Vesa 400x400

The back of the TV is plastic but looks quite good. Due to the OneConnect box, the only two cables into the back of the TV are the optical OneConnect cable and a power cable. These can both be hidden behind panels. The OneConnect box and the TV each require a separate power cable.

Borders
Samsung Q7F Borders Picture
Borders : 0.31" (0.8 cm)

The borders of the TV are very thin and look great. They have a similar design to the 2016 KS9000 with a polished metal finish.

The QLED TV is edge lit from the bottom as shown by the much higher temperatures along the bottom edge. This makes the bottom edge warm to the touch, but this shouldn't be a problem for normal usage. The One Connect box also gets warm, up to 41 °C, but again this shouldn't be a problem.

7.5 Build Quality
Samsung Q7F Build quality picture

The build quality of the Q7 QLED TV is an improvement over Samsung's 2016 models. The remote is exceptional, with a premium feel to the metal unibody. The central stand feels more sturdy than the KS9000 stand and although the back is made out of plastic, it clips into place securely which is an improvement over the glue on the KS8000.

7.8

Picture Quality

The Samsung Q7F LED TV has a good overall picture quality. It has an excellent contrast ratio and a good black uniformity making it a good choice for watching movies in a dark room. If set in a very bright environment this QLED TV might not be the best option since the brightness is average and might not be able to fight glare as well as a brighter TV. Even though the gray uniformity is good, the image degrades at an angle meaning that this TV won't be the best option for a large group watching an important sports event. When it comes to HDR, the poor local dimming and the just above average HDR peak brightness won't make HDR movies stand out as much as on other TVs, even though it has excellent wide color gamut coverage.

The native contrast ratio of the Q7F is great. With just over 5000, this high contrast ratio will provide a good movie experience, especially for those who watch movies in a dark room. This is slightly worse than the KS* TVs of 2016.

Edge

The local dimming of the Q7F edge-lit TV is not so great, like on most other edge-lit TVs. In fact, when compared side by side with the Samsung KS8000 the local dimming on both TVs look and behave almost the same. Vertical blooming is visible when there is a bright highlight. Note that on the Q7F, the local dimming cannot be totally turned off, the minimum setting is 'Low'.

The SDR peak brightness is average. When a 2% or 10% window is displayed the TV gets very bright initially, then it cycles between bright and dim approximately every 30 seconds. However the 2% and 10% window patterns are ideal cases for local dimming, so the TV won't be as bright during normal usage, as seen in our Real Scene brightness test.

Local Dimming was set to High for these tests. Other values weren't as bright.

The above results are for Movie mode calibrated to 6500k; in Dynamic mode many test patterns are brighter, as shown in the table below. Note that Dynamic mode isn't as true to the source material as Movie mode because it uses different settings, such as a cooler color temperature.

Real Scene: 366 cd/m2

The HDR peak brightness is above average. The TV cycles between bright and dim when displaying a 2% or 10% window. Local dimming brightens the smaller window sizes more than the larger ones, but the worst case brightness is still not bad. However the brightness of this Q7F is noticeably worse than the KS8000 and KS9000 from last year.

The above results are for Movie mode calibrated to 6500k; in Dynamic mode many test patterns are brighter, as shown in the table below. Note that Dynamic mode isn't as true to the source material as Movie mode because it uses different settings, such as a cooler color temperature.

The Samsung Q7 has an overall good gray uniformity. There is not too much dirty screen effect, but the overall uniformity is a bit worse than ideal. This is because both sides are relatively darker than the rest of the screen and the bottom also looks warmer than the upper part of the screen. There is a few brighter small spots on the bottom edge, but outrageous.

On the 5% gray uniformity picture the bottom of the screen looks a bit brighter near the edges. Besides that nothing really stands out which is a good thing.

The Q7F has good black uniformity. Some clouding can be seen on the screen while displaying our test image, especially in both left corners. On our test picture this clouding is a bit harder to notice, while the vertical blooming around the white cross is very obvious.

Note that we could not disable the local dimming feature completely to test the black uniformity of this TV, even in PC mode. This reduces the black uniformity due to the uneven brightness of the screen.

The gamma is not flat, but the overall value is still pretty close to the goal of 2.2 which is good. The color reproduction is pretty good, with only the cyan having a higher dE than other colors.

The calibration process is relatively easy to do with the 2 points, 10 points and color management system provided. With those tools, the white balance dE was brought down to a negligible 0.31 dE, which is excellent. The gamma value did not change too much (from 2.28 to 2.21), but the gamma tracks the 2.2 target much closer. The color error was brought down considerably, but even then the cyan is still a bit less precise than the other colors.

When using our warm calibrated settings, approximately half of the blue sub-pixel turns off (see a close-up of the pixels here). This results in some strange artifacts when close to the TV. We have seen a similar result with some TCL TVs such as the US5800. This isn't a significant issue as it is only visible with a warm color temperature when very close to the TV, and doesn't affect normal content very much.

When in the 'Movie' picture mode, the backlight uses PWM dimming to limit the backlight, even at the maximum backlight setting. As a result the oscilloscope results above are using the 'PC' icon, which doesn't limit the backlight. Although the 'LED Clear Motion' option exists in the TV menu, it doesn't actually reduce the flicker frequency of the backlight. The backlight dims, but continues to flicker at 120Hz. This is the same result as the KS9000 from 2016.

Smart OS : Tizen (2017)

Samsung's Tizen smart platform has received a visual overhaul for 2017. It now has a white theme and nicer animations, but unfortunately the animations are much less smooth due to frequent frame drops and stuttering. This doesn't affect the usability of the interface though, which is still fast and mostly lag free. The interface is easy to use and the simple layout helps you quickly find what you are looking for. Voice control on the remote works well, and it can even change settings when instructions like "brightness 10" are given. It is easy to play media directly on the TV through a USB drive.

The Samsung Q7F LED TV is a good TV, but it is priced above its competition. There are plenty of TVs still available that offer equal or even better performance at a lower price-point.

Sony X930E
55" 65"

For most people, the Sony X930E is a better buy over the Q7F. It gets much brighter, which is good for HDR, but also has a much better local dimming feature. It cannot display quite as large of a color volume, but the overall performance is better than the Q7F.

Samsung KS8000
49" 55" 60" 65"

The Samsung KS8000 is the predecessor to this year's Q7F. Surprisingly, it performs better than the new QLED TV in a lot of tests. Both contrast and peak brightness measure well above what the Q7F was able to output, especially in SDR. The Q7 does do better with color volume, and this does help with HDR content. However, it is impossible to justify the expense of the QLED TV over the previous model. Pick whichever you find at a lower price.

LG UH8500
55" 60" 65" 75"

The LG UH8500 only surpass the Samsung Q7 if used in a bright, wide viewing arrangement. The QLED TV will otherwise perform much better in every other situation. Some people might want to consider it over the Q7F .

LG B6
55" 65"

The LG B6 OLED TV is still the TV with the best picture quality we've tested so far. The Samsung Q7F does get slightly brighter, but it pales in comparison to the B6 in both contrast and viewing angles. The QLED TV has a slightly better color volume, but it isn't enough to warrant picking it over the less expensive OLED TV.

Samsung KS8000 LED TV vs Samsung Q7F QLED TV

Overall, our new QLED 2017 TV scores worse than all our KS* from last year, but not by much. Here are the notable differences with the KS8000.

  • Q7F has better design/build quality
  • KS8000 gets significantly brighter, especially in SDR (528 nits for KS8000 in 50% window vs 317 nits for Q7F)
  • KS8000 has better native contrast (6906:1 vs 5020:1)
  • Q7F has better response time, especially 0% to 20%
  • Q7F bigger color volume and gamut (roughtly 5% better)

Even at the same price, most people would be slightly happier with the KS8000.

Peak brightness measurements

We have contacted Samsung, and they say that our unit is out of spec due to the relatively low peak brightness measurements. We will continue to investigate and update the review as we obtain more information.

Update 03/10/2017: We've ordered another unit. We will test it, verify the results and update the review.

Update 03/15/2017: We bought another Q7F from Amazon and measured the viewing angle, contrast and brightness of this new TV. All of these results are in the same ballpark as our original findings.

There are uniformity issues with the new Q7F (shown above), but this is unlikely to invalidate the other testing areas.

Update 03/17/2017: We invited Samsung's engineers to our lab in Montreal. They confirmed the validity of our measurements of peak brightness on our two units using their equipment. They commented that peak brightness measurements are lower than specification, the Q7 should reach 1000 nits while viewing HDR in Movie mode. They are investigating the issue.

Hi you mentioned in the review Samsung is giving you another unit. Did you get a defective unit, and this review is based on that unit ? Hard to believe lower brightness, blacks not as good, viewing angles issue with the 2017 model, when that is what they are basing all their marketing on.
We do not accept review samples from manufacturers, we bought both of our Samsung Q7F from Amazon. Purchasing the TVs allows us to show units more representative of what a real customer might receive as well as keep them for an entire year to follow up on the reviews should firmware updates enhance their capabilities.

Really, that ugly hanging wire under the TV gets a 9.5 on design? I think you guys need to double-check your work. That's lazy design, not good design.

There is a cable management system integrated into the TV stand that can be used to completely hide the power cord and the cable that connect the OneConnect to the TV. Here are some pictures showing how the TV looks when the cables are passed through the stand. But even if it didn't have this cable management system, the overall design including the stand of the TV and the materials used in the construction are much better than last year's model.

Quite a disappointing review in the context of the promise from the 2017 CES.
It's still a good TV with a good incremental jump in color volume. It, however, cannot reach OLED TVs in overall performance.
3
Is the Ethernet port Fast Ethernet or Gigabit? This is important to know for streaming 4k content.
Samsung does not list the speed of the ethernet port of the Q7F so we cannot confirm the exact transfer rate, but we expect the ethernet port on most TV to be 100Mbps (or commonly named Fast Ethernet). In any cases, it should be fast enough since most streaming services recommend a minimum of 25Mbps for streaming 4k content.

As an installer, we have had issues with the one connect boxes of the past when mounting TVs onto the wall as slim as possible, due to the one connect cables not being CL2/CL3 rated (so we aren't allowed to run it through the wall). Is the optical cable for the new one connect box in wall rated? Or is there an extension/alternate cord that has the capability? This will be a nightmare to mount with a soundbar for clients that don't have more than two outlets behind the TV (99% of them)
Yes, It appears that the cable is in-wall rated. Samsung also sells a longer 15m version of the cable for easier management.

Does this TV save SDR and HDR settings separately in game mode? Unlike last year's models?
It doesn't. When the TV detects an HDR signal, it will change to the proper gamma setting automatically (ST. 2084) and change to the correct color space when it is set to auto. Other settings won't change, so to be sure you have the best settings, just set the 'Backlight' to the max and 'Local dimming' to 'High'.

I was comparing this Q7 to OLED E7 Sustained and peak brightness. I was amazed yes Q7 at times gets brighter. But overall the E7 OLED sustains that brightness plus the excellent black levels, you could say that E7 Black level crushes the detail but to each his own... Interesting to see how 2017 OLED performs (LG SONY, Philips) vs. 2017 LED TVs.
Most of the weight our peak brightness scores is based on our "Real Scene" test, as we've found that it is much more representative of the TV's actual performance when displaying a movie or other types of content. The LG E6 does indeed perform better than the Q7F in this aspect.

You guys always produce top quality reviews and this is no exception. I guess that's why I am so disappointed about the marks this television received from you. I was really looking forward to this being my first 4k TV... To say that the Q series was supposed to be the second coming of Christ would be an understatement - at least if you believed all the hype from Samsung. With that, in your opinion, can the 'flaws' be managed / fixed with software updates or are they hardware deficiencies? Again, thanks for all the hard work you put into your reviews.
It depends which flaws you are referring to. For example, the viewing angle cannot be fixed by a firmware update, since it is a limitation of VA LCD panels. The brightness is a mix of both software and hardware, since the algorithm to limit the brightness of the screen depending on the content is something that can be altered via an update.

Great review, amazing how LED comes back just when you think its over. Really 2 questions kind of general. How does this set compare to other brands 2016 models? And will you review the Q8? 2nd will you only review the Z9D (Best LCD) of 2016-possibly 2017. or just Sony's OLED?
In general, the Q7F is very similar to 2016 high-end models. It doesn't get quite as bright, and its uniformity isn't quite as good as the previous Samsung it replaces, but it can produce a much wider range of colors and has some very good handling of motion. You can suggest and vote on what TV is to be reviewed next on our Suggest a Review page.

Is the Q7F UHD Premium certified?
Yes, the entire 2017 QLED series has been certified UHD Premium. Source.

You summed up what I was seeing in my local Frys - an older 55"KS8K they were lowballing from the demo floor last week did not sell and it sat next to the new Q7's and I gulped. This pictures were virtually indistinguishable but the price had doubled. Right behind me were the demo LG OLED's which looked better and were $500 less. I expect prices to fall quickly in Q2 on Samsung QLED's.
Samsung historically has some of the most aggressive price reduction over time, but the QLED series of TVs launched at a higher MSRP than the previous KS line of TVs. The difference between them is indeed marginal and competing TVs are a better buy.
