LG UJ7700 Review (49UJ7700, 55UJ7700, 60UJ7700, 65UJ7700)
LG UJ7700 is a mid-end of LG’s 2017 4K HDR LED TV Lineup and also the successor of UH7700. In the market, it comes with four screen sizes option available including 49 Inch (49UJ7700), 55 inch (55UJ7700), 60 Inch (60UJ7700, and 65 Inch (65UJ7700). Overall, picture quality and performance of some features that offered are good and similar to the predecessor UH7700. Despite it lacks quantum dot panel technology where this becomes the major shortcoming of UJ7700 to the predecessor, but this cannot make the performance of UJ7700 series is worse than the predecessor.
On its panel, LG UJ7700 uses IPS panel with Edge Lit Backlighting and local dimming technology. As we know, one of the advantages of IPS panel is about the wide viewing angle coverage that offered. This certainly makes the picture displayed on its will look more consistent from side viewing angle. Like the predecessor, LG UJ7700 is also still focused on HDR technology where it is powered by Active HDR technology that already supports most of HDR formats available including HDR 10 by UHD Alliance, Dolby Vision by Dolby Laboratories, HLG (Hybrid Log Gamma) by BBC and NHK, and also advanced HDR by Technicolor. Still about HDR, it also has HDR effect feature that allows you to enjoy every videos with the quality close to 4K HDR. Meanwhile, for producing good picture quality, it is powered by the number of LG most advanced technology like Ultra Luminance, True Color Accuracy, Wider Color Gamut, and more. And for delivering smooth and clear picture quality when displaying fast moving images like fast movies or sport programs, UJ7700 series is powered by True Motion 120 Hz based on native 120 Hz refresh rate panel.
The other major advantage that offered by LG UJ7700 is about their smart TV platform where with WebOS 3.5 as its platform, it offers simple, attractive, and responsive smart TV platform with a lot of attractive and useful apps available. This certainly will make you more comfort when enjoying 4K HDR entertainment in your own home. With all features that offered, LG UJ7700 is sold at range $700 – $2000 depends on the screen sizes. Nevertheless, the price that offered could still change at any time.

LG UJ7700 Performance
Good or not the quality of the picture produced by LG UJ7700 depends on the light condition of the room where it is used. This is due contrast and black uniformity produced by UJ7700 series is below average. With just about 1100:1 of contrast ratio and 0.085 nits of black level, this certainly is not enough to make its dark room performance is good. This even makes blacks of images look tend to grey than really black and this will make dark scenes will be shown a bit washed-out. Additionally, when displaying HDR contents, low contrast of UJ7700 is also not quite strong to reveal detail images in shadow like what intended by HDR technology itself. With poor performance in dark room especially when displaying dark scenes, the use in a dark environment should be avoided.
Meanwhile, in a brighter room where low contrast is not as noticeable due there is ambient light, the problematic of UJ7700 when displaying dark scenes is a bit solved. This means dark scenes will looks better in a brighter room. On the other hand, when displaying SDR contents, the peak brightness reached by UJ7700 is not too bright so this is also not quite bright to effectively fight the direct glare. This certainly makes performance of LG UJ7700 is not so good when displaying SDR contents. When set in a dark room, it will get an issue on dark scenes, while when set in bright room, it will get a bit issue on bright scenes. Nevertheless, its performance will be different when displaying HDR videos. With about 640 nits of peak brightness on 2 % and 10% windows, this is quite bright to make small highlights of HDR videos looks great, no matter it was set in a dark room or a moderately bright room. But even so, it is not as bright as what reached by most of high end TVs and still not bright enough to display the highlight of HDR images at least 1000 nits like what intended. This certainly will make a bit other issue when it is set in an extremely bright room where there is sunlight coming in through the windows. Nevertheless, overall, picture quality of UJ7700 is good for its class, as long as you don’t use it in a dark room or an extremely bright room.
Meanwhile, lack of quantum dot panel technology doesn’t make its color performance is worse than the predecessor UH7700. Although color gamut that can be covered by UJ7700 is not as wide as high end TVs, but at least, it already support wide color gamut and offers better color performance than the predecessor UH7700. This means when it is displaying DCI P3 Color space of HDR videos, some colors might be shown over saturated, but overall, color of the picture displayed on the screen of UJ7700 looks very accurate, even when displaying HDR videos that require wide color gamut. While when displaying SDR contents that only require Rec.709 color space, LG UJ7700 certainly is able to do a great job. In addition to it can deliver accurate color, LG UJ7700 is also able to process 10 bit depth of color well, even better than most of TVs. This means it can deliver about 1.07 billion shades of color that make color gradient of the picture produced looks very smooth. Despite some imperfections might still be noticeable in darker green, this should not be a major problem that would be annoying.
The other great performance that offered by LG UJ7700 is its UHD Up-scaling engine called Tru 4K Up-Scaler. With this feature, no matter the resolution of the sources, you will enjoy them with the quality close to 4K sharply and clearly. Even for 480p videos like DVDs movies, the final images in 4K which resulted don’t look too soft with details still preserved well. And of course, when the source has higher resolution such as 720p contents or 1080p contents, the final images in 4K which resulted looks sharper and detailed. And considering the low resolution contents are still widely available in the market, this feature certainly is still very important.
The use of IPS panel might make black level and contrast produced by LG UJ7700 is weak, but on the other hand, this makes UJ7700 has wide viewing angle coverage. Although it is not as good as what offered by OLED TV, but it is far better than VA TVs, even still better than most of IPS TVs. This means the picture quality will looks more consistent when the TV is viewed from side viewing angle. But even so, from extremely side viewing angle, the picture degradation is still noticeable caused by the color shift and the decreases of brightness. Meanwhile, black level still look consistent at any angle.
Motion Handling and 24p Playback
LG UJ7700 has a good motion handling. This means when it is playing fast moving images like sport program or fast movies, the picture displayed will looks smooth and clear with almost no motion blur noticeable. Its pixel response time is very fast, faster than most of TVs. The result, there is only a short trail of motion blur following fast moving objects that should not be annoying. Meanwhile, when displaying 24p movies, it only does a good job when displaying 24p movies from Blu ray where the picture produced looks very smooth with judder-free. But when displaying 24p contents via 60i/60p signals like movies from Satellite TV or Streaming Media, performance of UJ7700 is not so good due it cannot completely remove the judder. Nevertheless, since most of people don’t sensitive to judder, this certainly is not a major issue for most of people. Additionally, since LG UJ7700 has native 60 Hz refresh rate panel, it is only support 30 fps motion interpolation only, while for 60 fps interpolation, it doesn’t.
As the major connectivity, LG UJ7700 is equipped with 2 USB Ports and 4 HDMI ports support HDCP 2.2. Additionally, there are also Composite IN, Component In, RF In (Terrestrial), Ethernet Ports, and Digital Audio Out (Optical). With all inputs/outputs provided by UJ7700, I think they are enough to cover most or even all of your other electronic devices. Meanwhile, the input lag of UJ7700 is extremely low under “Game Mode” and “PC Mode”. With about 11 ms of input lag at any source, this certainly makes UJ7700 is including the one of TVs with the best input lag. The outstanding input lag that offered by UJ7700 also makes it is very comfortable when used for any kind of games with any resolution, even for fast paced games that require fast reflexes. Additionally, the low input lag under PC Mode also makes very comfortable when used as the PC monitor.
As the smart TV platform, LG UJ7700 features WebOS 3.5, the newest version of WebOS. As we know, WebOS is a smart TV platform which has a lot of low-level options but it still offers simple navigation. The user interface and layout is also designed attractively with strip bar at the bottom of the screen contains quick access to most of popular apps. Additionally, its performance is fast and responsive. Once an app is launched, the loading in time is very fast. Additionally, selecting between apps or multitasking also feels very responsive. Meanwhile, talking about apps provided, there are plenty of interesting and useful apps available. There are VoD apps like YouTube, Netflix, Amazon Videos, Hulu, Google Play Movies and more, web browser, LG Contents Store, Social Networking, and many more. A bit difference to older version WebOS 3.0 is about the Magic Link, a content recommendation service powered by LG, and Channel Plus, an aggregate of 70-plus free streaming digital channels. Meanwhile, overall, it is similar to last year version WebOS 3.0.
As the controller, LG UJ7700 comes with LG’s Magic Remote. Like last year version, there is built-in remote for voice navigation functionality. The most advantage is about “point and click” that has a function like a mouse on your PC. This certainly makes inputting the text, surfing on the internet, and other navigation feel easier.
Overall, LG UJ7700 is a good TV for its price range, no matter you use it for watching TV shows, movies, sport programs, playing games, or as a PC monitor. As long as you don’t use it in a dark room or an extremely bright room, the quality of the picture displayed on its screen looks good. Additionally, come with HDR, it already supports most of HDR formats and its HDR performance is also very good. Nevertheless, since it doesn’t has strong contrast and very bright peak brightness, it is not certified by Ultra HD Premium Certification that means it cannot display HDR 10 videos fully like what intended. Additionally, LG UJ7700 also offers some great performance of some features like UHD Up-scaling Engine, wide side viewing angle, and others. Motion handling is good that makes it is comfortable for watching fast moving images. The input lag is also extremely low that makes it is also very comfortable for any kind of games. And that is not less interesting is about its smart TV platform where it comes with WebOS, the one of the best smart TV platforms.
Should I buy this TV? As long as you don’t have a plan to use it in dark room or extremely bright room, this TV might be a good option for you. Moreover, it comes with IPS panel that has wide viewing angle coverage. It is very suitable to use in a wide room with viewers come from multiple viewing angles.
