LG SM9000 vs Samsung Q70R Review (55SM9000 vs QN55Q70R, 65SM9000 vs QN65Q70R), 75SM9070 vs QN75Q70R)
LG SM9000 is the second top model of LG’s 2019 4K HDR LED TV lineup. In this lineup, it sits between the top model SM9500 and SM8600. And just like most model of LG’s LED TVs, the SM9000 also comes with IPS panel technology that make it has good side viewing angle coverage. But as we have known, a TV with IPS panel usually has weak contrast ratio and it is also as true to the SM9000. On the other hand, the Samsung Q70R is the mid-range model of Samsung’s 2019 QLED TV lineup. It sits between the Q80R and Q60R. In contrast to the SM9000 that comes with IPS panel, the Q70R comes with VA panel technology that makes it has excellent native contrast ratio. But on the other hand, a TV with VA panel usually has poor side viewing angle and it is also as true to the Q70R.
In the market, the Samsung Q70R comes in 6 screen sizes options including 49 inches (QN49Q70R), 55 Inches (QN55Q70R), 65 inches (QN65Q70R), 75 inches (QN75Q70R), 82 inches (QN82Q70R), and 85 inches (QN85Q70R). On the other hand, the LG SM9000 is only available on 4 screen sizes option including 55 inches (55SM9000), 65 inches (65SM9000), 75 inches (75SM9070), and 86 Inches (86SM9070). And with the same screen size (55SM9000 vs QN55Q70R, 65SM9000 vs QN675Q70R, 75SM9070 vs QN75Q70R), the Q70R is priced more expensive than the SM9000, except for their 75 inches where they have the same price. But of course, their prices are not fixed and could be still change at any time. So, which is superior and a better choice between them?

Technologies and Features of Samsung Q70R and LG SM9000
The Samsung Q70R and LG SM9000 use different panel technology. Just like other models of each of their lineup, the Q70R uses VA panel with Quantum Dot technology while the SM9000 uses IPS panel with Nano Cell Technology. Whether it is quantum dot technology on the Q70R and Nano Cell technology on the SM9000, these technologies have the same role, which is for improving their color production. Meanwhile, as we have known, a TV with VA panel usually has good native contrast ratio but on the other hand, its side viewing angle coverage usually is poor. On the contrary, a TV with IPS panel usually has good side viewing angle coverage but on the other hand, its native contrast ratio is poor.
Even though both LG SM9000 and Samsung Q70R use different panel technology, but they use the same technology, which is Direct LED backlight with Full Array Local Dimming (FALD. This is certainly good considering the FALD technology can improve their performance in a dark room. But unfortunately, there is no official information about how many dimming zones of each of their local dimming.
As their processor, the Samsung Q70R is powered by Quantum Processor 4K while the LG SM9000 is powered by the Alpha 7 Gen 2 processor. We will not discuss a lot about these processors, but basically, both of these image processors make possible both Q70R and SM9000 have some AI (Artificial Intelligence)-related features.
Both Samsung Q70R and LG SM9000 actually support almost the same HDR formats, which are HDR 10 and HLG (Hybrid Log gamma). Nevertheless, that distinguishes between them is about dynamic HDR format that supported by them. As we see on comparison table above, the SM9000 supports Dolby Vision while the Q70R supports HDR10+.
The excepting of its 49 inches model (QN49Q70R), the Samsung Q70R is powered by Motion Rate 240 while the LG SM9000 is powered by TruMotion 240 technology. Nevertheless, basically, these technologies are based on native 120 Hz refresh rate panel. In addition to native 120 Hz refresh rate panel, they both also already support Variable Refresh Rate technology where the Q70R supports FreeSync VRR while the SM9000 supports HDMI Forum VRR. As we have known, the VRR technology can improve their game experience with almost free screen-tearing. Special for the 49 inches model of the Q70R (QN49Q70R), it has native 60 Hz refresh rate panel and is powered by Motion Rate 120. It doesn’t also support VRR technology.
Meanwhile, to dim their backlight, they both use PWM Dimming system but with different dimming frequency. The highest dimming frequency of the Q70R is 960Hz where it is reached when the TV is set to “Movie” mode with Auto Motion Plus is disabled. Meanwhile, in “Standard” or “Game” modes or when the “Auto Motion Plus” is set to “Custom” or “Auto” regardless the mode of TV, its dimming frequency changes to 120 Hz. The Q70R also already supports a 60 Hz BFI (Black Frame Insertion) that makes their dimming frequency change to 60 Hz and can help to make motion clearer. To activate its BFI mode, the “LED Clear Motion” must be set to “On”.
On the other hand, in most modes, the dimming frequency of the LG SM9000 is 120 Hz. But even so, just like the Q70R, the also has an optional BFI mode that will change its dimming frequency to 60 Hz. To enable this feature, you can enable “Motion Pro”. Keep in mind, enabling their BFI mode may be able to help motion clearer on their screen, but on the other hand, this will makes their backlight flicker is more noticeable, particularly for the people who sensitive to flicker.
As their major connectivity, the Samsung Q70R and LG SM9000 both have 4 HDMI ports. Their HDMI ports support HDMI 2.0, HDCP 2.2, ARC (Audio Return Channel), CEC and ALLM (Auto Low Latency Mode). The advantage of SM9000, its HDMI ports also already supports HDMI 2.1 and eARC (enhanced Audio Return Channel) while the ports of the Q70R doesn’t support. This allows the SM9000 supports HFR (High Frame Rate) content such as 4K @ 120 Hz content.
Meanwhile, the LG SM9000 has a bit more USB ports than the Samsung Q70R where the SM9000 has 3 ports while the Q70R has 2 ports only. But even so, all of their USB ports are USB 2.0 and none of them is USB 3.0. In addition to HDMI and USB ports, they both have 1 RF In (Tuner In), 1 Ethernet port, and 1 digital Audio Out (Optical). The SM9000 also has Composite In (AV IN) while the Q70R doesn’t have this type of inputs.
Smart TV Platform
As their Smart TV platform, the Samsung Q70R runs Tizen 2019 or called Smart Hub while the LG SM9000 runs WebOS 4.6. Their interface is equally simple, intuitive, and easy to use. There are almost no issues with their interface. Additionally, they both also provide a lot of attractive and useful preinstalled apps. There are VoD (Video on Demand) like YouTube, Amazon Videos, Netflix, etc, Web Browser, Live TVs, Games, and many more. If Tizen OS has SmartThing, WebOS has Home Dashboard where both of these features allow them to interact with many loT devices. Not only that, both of these smart TV platforms are also compatible with Google Home, Amazon Alexa, and AirPlay 2. As their apps store, Tizen OS has Samsung Apps Store while WebOS has LG’s Apps Store where both of these apps stores provided tons of downloadable apps, games, and others albeit actually, apps provided by Samsung Apps store are more complete than what provided by LG Apps Store. And to make the navigation is easier and faster, they both also already have built-in navigation where the Q&0R works with Samsung’s Bixby 2 while the SM9000 works with LG ThinQ AI.
As their controller, the LG SM9000 comes with LG’s magic remote while the Samsung Q70R comes with Samsung Smart Controller. The LG’s remote is large and has a lot of buttons. On the contrary, the Samsung’s remote is small and only has few buttons. Nevertheless, they both have a lot of smart features. Work with Samsung Bixby for Samsung’s remote and ThinQ Ai for LG Remote and equipped with built in microphone, they both have excellent voice control. Their remote can also act as a universal remote over IR. This means, not only other devices that support HDMI CEC that can be controlled by their remote, but also other devices that don’t support HDMI CEC. Meanwhile, the advantage of the LG’s remote, it also can be used as a virtual pointer that certainly makes navigation is much easier. This function is like the function on WII’s remote.
Samsung Q70R vs LG SM9000 Performance
Contrast and Black Level
The Samsung Q70R has outstanding native contrast ratio. Its native contrast ratio is even including the one of the highest that ever, which is more than 7000:1. The result, black produced by the Q70R is very deep, deep enough to make black looks really black in a dark room. Additionally, even though not as good as the series above it like Q80R or Q90R, the Q70R also has local dimming that can improve its performance in a dark room. In addition to slightly improve its contrast ratio, its local dimming is also able to minimize blooming, that means it is good for displaying small highlight in a dark scene. But of course, its performance in minimizing blooming is not as good as the series above it that have more dimming zones. Overall, with its excellent contrast ratio, a dark room performance of the Q70R is really excellent, even when displaying dark scene.
While the Q70R has outstanding contrast ratio, the native contrast ratio of the LG SM9000 is very poor, less than 1000:1. The result, it cannot produce deep black. In a dark room, black produced by the SM9000 even looks tend to gray than really black. This mean, in a dark room, dark scene cannot be shown well on its screen. The SM9000 may have local dimming, but its local dimming is unable to noticeably improve contrast. So, even though its local dimming is enabled, their contrast ratio is not improved significantly, even tend to be similar. Just like on Q70R, its local dimming actually is able to minimize blooming, but not as good as the SM9500 that has more dimming zones. Overall, with its poor contrast ratio, the SM9000 is not suitable when used in a dark room.
Winner: Samsung Q70R
SDR Peak Brightness
The Samsung Q70R has brighter SDR peak brightness than the LG SM9000. With real content, the maximum luminosity that reached by the Q70R is approximately 450 nits while the SM9000 reach approximately 350 nits. This means, the Q70R can show brighter SDR images than the SM9000. The result, in brighter room, details in images displayed on the screen of the Q70R will looks better than on the screen of the SM9000. Nevertheless, although not as bright as the Q70R, peak brightness reached by the LG SM9000 actually is bright enough to fight glare in most bright rooms.
Winner: Samsung Q70R
HDR Peak Brightness
Meanwhile, with a HDR Signal, the Samsung Q70R and LG SM9000 are able to hit brighter peak brightness than when with SDR Content. And just like with SDR content, the Q70R can reach brighter peak brightness than the SM9000. With real content, the Q70R is able to hit approximately 750 nits while the SM9000 is able to hit approximately 450 nits. Meanwhile, with a test pattern, peak brightness reached by them have different characteristic. The Q70R can reach its brightest peak brightness on 10% window (10% of screen is white while when the rest is black) where it can reach approximately 750 nits. Meanwhile, on 2% and 25% window, it hit around 650 nits and as the bright area increases, its peak brightness is decreased down to around 450 nits on 100%. This means, the Q70R can show small highlight fairly bright, as bright the way they should in HDR.
On the LG SM9000, for a short time, it actually is able to show small highlight very bright, which is around 450 nits on 2% window and 900 nits on 10% window. But unfortunately, its peak brightness on 2% window is aggressively dimmed to around 150 nits by the TV and on 10% window is aggressively dimmed to around 300 nits. This means, for a long time, small highlight of HDR looks too dim on the screen of LG SM9000. Nevertheless, overall, with HDR content, peak brightness of LG SM9000 is decent and at least, it can show HDR images brighter than SDR images.
Keep in mind, all of these results are reached by certain setting. For the Q70R, the picture mode is set to “Movie”, Color Tone is set to “Warm 2” and Local Dimming is set to “High”. Meanwhile for SM9000, the picture mode is set to “Cinema HDR”, Backlight is set to “100”, Color Temperature to “Warm 2”, and Local Dimming set to “High”. With other setting, the Samsung Q70R and LG SM9000 may get brighter maximum brightness, but this can cause the image lose its accuracy.
Winner: Samsung Q70R
Color gamut and Color Volume
Both Samsung Q70R and LG SM9000 supports wide color gamut and their color gamut is almost similar. In DCI P3, their color gamut coverage is approximately 93%, wide enough to accurately show colors of HDR images that mastered in DCI P3 like HDR10. Meanwhile, in Rec.2020, their color gamut is also almost similar, which is approximately 74% for Q70R and 72% for LG SM9000. Special for LG SM9000 that support Dolby Vision that is mastered in Rec.2020, its color gamut is also wide enough to show most colors of Dolby Vision Content fairly accurately.
Additionally, both LG SM9000 and Samsung Q70R also have similar color volume and their color volume is decent. Just like most LCD TVs, they both cannot produce very bright blues. Special for the SM9000, since it has weak native contrast ratio, it cannot also produce deep dark. But except dark colors and very bright blues, overall, the SM9000 can show its wide color gamut at entire brightness range. On the other hand, even though the Samsung Q70R cannot also produce very bright blues, but overall, dark and bright colors can be shown fairly well on its screen.
Winner: Samsung Q70R
While their color gamut and color volume is almost similar, the LG SM9000 has better color gradient than the Samsung Q70R. On the screen of the SM9000, color gradient of HDR images displayed on its screen looks very smooth. In areas of similar colors, there is only very little noticeable banding, that means it is great. On the other hand, on the screen of the Q70R, there is some fine banding in almost all dark shades. Fortunately, this is hard to notice, so this should not be a problem for most people. But even so, if you still feel banding is bothering you, set “Digital Clean View” to “Auto” can eliminate most of banding. On the SM9000, it actually also has a feature called “Smooth Gradation” that has similar function like “Digital Clean View”. But keep in mind, enable these features may cause the images displayed on their screen lose some fine details.
Winner: LG SM9000
Side Viewing Angle
The use of IPS panel may cause the LG SM9000 has weak native contrast ratio, but on the other hand, this makes it has good side viewing angle coverage. It can maintain its black level up to approximately 70 degrees off center and front which means it is good. Additionally, it also can maintain its color accuracy up to around 60 degrees. Nevertheless, brightness level still decreases at around 35 degrees. What offered by the SM9000 may be not as good as OLED TVs, but still better than VA TVs, even that has optical panel that designed for improving side viewing angle like Ultra Viewing Angle on Samsung Q80R or Q90R or X Viewing angle on Sony X950G.
On the other hand, as expected for a TV with VA panel, the Samsung Q70R has poor side viewing angle. It lacks Ultra Viewing Angle optical panel found on the series above it such as Q80R or Q90R. Black level starts to rise at around 15 degrees off center and front. Additionally, color also starts to shift at around 25 degrees. The result, when viewed from an angle, the images displayed on its screen looks inaccurate. This means, if you have a room with wide seat arrangement for watching TV, this TV is not suitable for you.
Winner: LG SM9000
Both LG SM9000 and Samsung Q70R have excellent pixel response time and their responsive is almost similar, which is approximately 14 ms. Their response time is low enough to make motion looks very smooth on their screen when they are playing fast moving images like sports or fast movies. Following fast moving object, there is only a faint short trail that should be hard to notice.
Just we have discussed above, since the LG SM900 has120 Hz backlight flicker and in most modes, the Samsung Q70R also has 120 HZ flicker, when playing 60 fps content, this may cause some duplication. But don’t worry, they both have an optional 60 Hz BFI (Black Frame Insertion) mode that can help to make motion looks clearer. To enable their BFI mode, just we have discussed above, for Q70R, you just need “LED Clear Motion” to ”On” and for SM9000, you just need to enable “Motion Pro”. But keep in mind, enabling this feature may can help to make motion clearer, but on the other hand, this will cause their backlight flicker bother some people who sensitive to flicker.
Meanwhile, when playing 24p movies, both LG SM9000 and Samsung Q70R can do great job. Regardless the source, both of them can show movies with judder-free. This means, whether you are playing movies from DVD or Blu Ray Player, Streaming devices, Satellite TV, Native Apps like Netflix, Amazon Videos, ad others, you will enjoy them with judder-free. But to remove the judder, you must make some certain setting. On Q70R, you must set “Auto Motion Plus” to “Custom” and set both sliders to “0”. Meanwhile, for SM9000, you just must enable “Real Cinema” from the Picture Mode Setting.
Both of the Samsung Q70R and LG SM9000 have excellent input lags in Game Mode and which is a lower between them is depending on the frame rate of content. With 60 fps content, regardless the resolution, the input lags of the SM9000 is approximately 14 ms while the input lags of the Q70R is around 15 ms. On the contrary, with 120 fps content, the input lags of SM9000 is around 7 ms while the Q70R is around 6 ms on both 1440p and 1080p resolution. But even so, ignoring their difference, their input lags are low enough to play any game responsively. The excellence, they both also already support VRR technology that can improve their game experience with screen tearing-free. Samsung Q70R supports Free Sync VRR while the LG SM9000 supports HDMI Forum VRR. But unfortunately, special for the SM9000, HDMI VRR is not supported by many devices, and for this now, there is only X Box one that supports this format. In Addition to VRR technology, they both also support ALLM (Auto Low Latency Mode), allow them to automatically change to game low latency mode like Game mode once the signal from a game console is detected on their HDMI ports.
For Watching Movies
Since most people prefer watch movies in a dark room, of course, Samsung Q70R is better than the LG SM9000 when used for watching movies in a dark room. This is due to the Q70R has deep black that makes its dark room performance is good. Additionally, it also has local dimming feature that cab improve its performance in a dark room. On the other hand, since the SM9000 uses IPS panel, this cause its contrast ratio is poor, makes its dark room performance is not so good. It may also have local dimming feature, but this feature cannot do a lot to improve its dark room performance. But even so, once it is used in a bright room, its performance when used for watching movies is much better.
Winner: Samsung Q70R
For Watching Sports
Unlike when watching movies, most people prefer to watch sports in a bright room with a group of friend or family. And for this case, the SM9000 is a bit better than the Q70R. They both may have similar pixel response time that makes fast sports looks smooth on their screen. They both also have bright enough peak brightness to fight the glare in a bright room. Additionally, their gray uniformity is also almost similar, allow them to show field of football or baseball without a lot of dirty screen effect. But even, the advantage of the SM9000, it has better side viewing angle than the Q70R. This allows all of you get the best viewing when you are watching a big game with a group of your friend or family. Meanwhile, since the Q70R has poor side viewing angle, when you are watching a big game with a group of your friend or family, some of you may not get the best viewing.
Winner: LG SM9000
For Playing Games
Both Samsung Q70R and Samsung SM9000 actually are great TVs for playing games. They both have excellent pixel response time and excellent input lags, allow you to play fast paced games responsively with smooth picture. Additionally, they both also already support VRR technology that can improve their game experience. But even so, for this case, the Q7R is a bit better than the SM9000. This is due to it already supports FreeSync VRR technology that supported many devices. On other hand, the SM9000 supports HDMI forum where this technology is not supported by many devices. Even for this time, there is only X Box One that supports this format.
Winner: Samsung Q70R
The Samsung Q70R is better than LG SM9000 when used for watching HDR content. This is due to it has deeper black level and brighter HDR peak brightness than the SM9000. On the screen of the Q70R, details of HDR images in both dark and bright scene can be shown excellently the way they should be. Nevertheless, since the peak brightness of the Q70R is still below than 1000 nits, albeit it can show highlight of HDR images as bright the way it should in HDR, but it cannot still show highlight of HDR images at 1000-4000 nits intended by the content creator. On the other hand, when used for watching HDR content, performance of the LG SM9000 is not as good as the Q70R. It cannot produce deep black that makes shadow details cannot be shown excellently. Additionally, although with HDR content it actually can get fairly bright, but it is not still as bright as the Q70R.
Winner: Samsung Q70R
|Smart TV Experience
As we have discussed a lot above, the LG SM9000 and Samsung Q70R use different panel technology, each with weakness and strength than each other. Samsung is superior in black level and peak brightness while the LG SM9000 is better in side viewing angle. But even so, overall, the Samsung Q70R has better performance than the SM9000 for most usage. Nevertheless, this doesn’t mean the Q70R is better choice. Which one is better choice between them certainly is depending on your purpose. If your main purpose in buying TV is for watching movies, the Samsung Q70R certainly is a better choice. On the other hand, if you want to place the TV in a room with wide seating arrangement, the LG SM900 certainly is a better choice. Now, the decision comes back to you according to your preferences and need.
