LG UK7700 Review (55UK7700PUD, 65UK7700PUD)
LG UK7700 is best model of LG’s 2018 UHD TV lineup. Still coming with IPS panel, it lacks Full Array Local Dimming Technology that the SUHD Series like SK8000 or SK9000 have. Instead, it comes with Edge lit-backlight with local dimming. But the good news, for its price level, it still offers the number of LG’s most advanced technologies and features found on the series above it like Nano Cell Display, Active HDR, LG AI ThinQ, LG Magic Remote, and others. Picture quality and performance offered may be not as good as the series above it like SK8000 or SK9000, but at least, its picture quality and performance is not too far behind them. But it offers the benefits in its price that is more affordable. In the market, it is available in 2 screen sizes option including 55 inch (55UK7700PUD) and 65 inch (65UK7700PUD) and comes to mid-range class.

Technologies and Features of LG UK7700
As we have mentioned, LG UK7700 may lack some advanced technologies like FALD, Dolby Vision, Dolby Atmos, Alpha 7 Processor, and others found on the series above, but it still brings some other LG’s advanced technologies. On its panel, it still uses IPS panel technology that offers good viewing angle coverage. Additionally, although it lacks Full array local dimming, instead, it comes with local dimming technology, but for this case, it uses edge-lit backlight. Meanwhile, for maximizing its performance in producing colors, like the series above it, it is also powered by Nano Cell Display technology, a variant of quantum dot technology designed for IPS panel. Additionally, for improving black produced, there is Nano Cell Black technology behind it. And for maximizing peak brightness, LG UK7700 is powered by Ultra Luminance Technology.
LG UK7700 may lack Alpha 7 processor found on the higher series SK8000 or SK90000, but instead, it is powered by a quad core processor where its performance in processing images is not far behind Alpha 7 processor. Maximized for HDR experience, it comes with the number of features like HDR effect and Active 4K HDR. But unfortunately, unlike the series above it that support Dolby Vision and Advanced HDR by Technicolor, UK7700 only supports HDR10 and HLG. Nevertheless, I think HDR 10 and HLG are also more than enough considering most of HDR contents available in the market are mastered in HDR10. Meanwhile, with HLG format, it allows you to enjoy TV broadcast with HDR quality. Not even just that, with active 4K HDR, HDR effect, and Tru 4k Up-Scaler, it allow you to enjoy non UHD content with the quality as close as possible to 4K HDR. And for maximizing its performance in handling motion and 24p movies, LG UK77000 is powered by TruMotion 120 Hz based on native 60 Hz refresh rate panel. This actually is lower than SK8000 considering it is powered by TruMotion 240Hz based on native 120 Hz refresh rate panel.
The one of the highlight brought by LG TVs including UK7700 in this year is about its Smart TV platform. Like other model of LG’s 2018 4K TV lineup. It is also featuring WebOS 4.0 as its smart TV platform, the latest version of WebOS. But the interesting, now, its smart TV platform has been integrated with LG AI ThinQ, an artificially intelligence app by LG. With AI ThinQ, you can control and monitor your ThinQ compatible devices like Air Conditioner, Dish washer, Refrigerator, and others via your LG TV. Not only ThinQ devices, but also Amazon Alexa and Google Home compatible devices due it is also compatible with Amazon Alexa and Google Home. Additionally, LG AI ThinQ also makes its navigation is far excellent. In addition to it can be used to navigate your TV with your voice commands, it also allows you to control ThinQ, Amazon Alexa and Google Home device connected on your TV with your voice command.
LG UK7700 Performance
Like other TVs with IPS panel, LG UK7700 cannot also produce deep black level. Its native contrast ratio is only around 1000:1 with deepest black level produced is around 0.01 nits. Coming with local dimming doesn’t help improve its contrast ratio. Black level produced by it is not deep enough to makes black looks really black in a dark room. The result, when it is set in a dark room, black of image will tend to look grey than really black. Additionally, poor black level produced by it also makes darker color cannot be shown fairly accurate, make dark scene of images can be shown excellently and naturally. And of course, black level produced by UK7700 is also not deep enough reveal details in dark scene of HDR images like what recommended, makes shadow details of HDR images produced is still far from what intended by content creator. So, if you buy UK7700 in order to be able to enjoy shadow details of HDR images like the intended, you might be disappointed. This means, if you often watch TV in a dark room or often watch movies with a lot of dark scene, this TV may be not a good option for you. But fortunately, although still not as good as a TV with deep black level, once it is set in a bright room, dark scene of image displayed on its screen will looks far better.
While performance of LG UK7700 in a dark room is not so good due it has low contrast ratio, in a bright room, its picture quality will look better. However, this is also limited in a dimly-lit room or a room with normal light. With SDR content, its peak brightness is still less than 300 nits. This means it is only bright enough to maintain picture quality produced in a dimly-lit room or a room with normal light, while when set in a brighter room, its peak brightness is not bright enough to fight the glare. Additionally, with HDR contents, its peak brightness may be a bit brighter but still less than 300 nits. In a very bright room with much light, HDR images displayed on its screen will look too dim. This means, you will not get the advantage of increased brightness range offered by HDR. And of course, peak brightness produced by LG UK7700 is also still far from 1000 nits as the minimum recommendation to show HDR images like the creator intended.
Powered by Nano Cell Display, this doesn’t make it can produce color gamut as wide as what produced by SK8000 or SK9000 that also powered by Nano Cell Display. But at least, it still has good color coverage in DCI P3. In DCI P3, its color gamut coverage is still less than 90% that means its color gamut is still less wide to show colors of HDR images like the intended. Nevertheless, most of colors in DCI P3 can be still covered fairly well and only some certain color light deep greens and others that can be shown as saturated as other colors. So, although not as accurate as the series above it like SK8000 or SK9000, colors of HDR images produced by it still looks fairly good. Meanwhile, like we have a bit mentioned above, the inability of UK7000 in producing deep blacks makes its color gamut narrows significantly in darker colors, particularly in very deep colors. But even so, except dark colors, its color volume is only limited by its own color gamut. This means, except dark colors, UK7700 can show its color gamut at its entire brightness range. The result, although not as accurate as the series above it, overall, colors of HDR images produced still looks fairly good on its screen. Still about color performance, LG UK7700 already supports 10 bit depth of colors that means it can produce more than 1 billion shades of colors. The result, color gradient of HDR images displayed on its screen looks very smooth. Although there are still some imperfections in certain colors, but this is not too major and should not be a problem when playing normal content.
Side Viewing Angle
Although not as excellent as OLED TV, LG UK7700 with IPS panel has good side viewing angle coverage, far better than a TV with VA panel. The excellence of IPS panel is in maintaining its black level of the picture when viewed from the side. If on VA panel, black typically will look degrade started at less than 15 degrees off center and front, on its screen, blacks will look remain black, even when viewed from extremely wide angle. But for this case, brightness and colors of the picture displayed on its screen still look degrade started at less than 30 degrees off center and front. Nevertheless, from the side, the picture displayed on its screen will look more consistent and better than on the screen of VA panel. With its good performance in maintaining picture quality produced from the side, this TV is very suitable for a room with a lot of viewers watch TV from multiple angles.
Motion handling and 24p Playback
Although not as low as the competitor like Samsung NU8000 or others, essentially, LG UK7700 also already has excellent pixel response time. This is very useful when it is playing fast paced content like fast movies, sports, or games. The picture displayed looks smooth and clear with only short ghosting trail following fast moving object where most people may not notice this much. Blur may still be visible, but this is more caused by persistence than pixel response time. Meanwhile, since it has local dimming technology, to dim its backlight, UK7700 uses PWM dimming system with 120 Hz of dimming frequency. This frequency actually is not high enough to make its screen is almost free from flicker. The result, flicker will be more visible on its screen than a TV with a higher dimming frequency, particularly for the people who sensitive to flicker. On the other hand, LG UK7700 is also doesn’t has a 60 Hz BFI mode like the series above it or the competitors. But even so, since it also already has 120 Hz dimming frequency and although not as effective as 60 Hz flicker, this actually already help to make motion looks clearer, particularly that caused by persistence.
Meanwhile, when playing 24p movies, its performance is a bit disappointing. It can show smooth and clear picture quality with judder-free only if the source is native 24p movies like DVD or Blu Ray’s movie or movies from streaming apps like Netflix, YouTube, Amazon Videos, or others. While when the source is 24p videos via 60i signal like movies from satellite TV or via 60p signal like movies from streaming devices, it cannot remove the judder completely. This means in certain scene, judder is still visible. Fortunately, most people doesn’t sensitive to judder, so if you are including those who don’t sensitive to judder, this should not be a problem for you. On the other hand, since LG UK7700 has native 60 Hz native refresh rate panel, it can only interpolate 30 fps at 60 Hz only.
For connecting with other devices, LG UK7700 provides 4 HDMI ports as its major connectivity. All of its HDR ports are already compatible with most HDMI features like HDCP 2.2, CEC, and HDMI 2.0 Full Bandwidth. Additionally, it also has 1 port that supports ARC that is HDMI 2. It may not support HDMI 2.1, but since it only has native 60 Hz performance and doesn’t support HFR (High Frame Rate) content, this doesn’t have an impact to its performance. Additionally, UK7700 is also equipped with 2 USB ports where all of them are USB 2.0. In addition to HDM and USB ports, it also provides some other inputs/outputs like 1 RF IN (Terrestrial), 1 Composite In (AV In), 1 Component In, 1 Digital Audio Out (Optical), and 1 Ethernet port. It is also equipped with Built-In WI-Fi for wireless connectivity.
The excellence offered by LG UK7700 is about its input lags. In “PC” and “Game Mode”, its input lags are less than 15 ms, no matter the resolution of the source. This is great for games, allow you to play any game comfortably and responsively without laggy, even for fast paced games that require fast reflexes. In 2018, the input lag of UK7000 is even including the one of the best.
As we have a bit discussed above, like most models of LG’s 2018 TV lineup, as its smart TV platform, LG UK7700 is featuring WebOS 4.0. But that distinguishes to the above series it is about the processor that support their smart TV performance. If the series above it is already powered by Alpha 7 or Alpha 9 processor, LG UK7700 is powered by quad core processor. This makes its performance is not as fast and responsive as the series above it. But even so, its performance is still more responsive and faster than the competitors. In term of apps or features offered, its smart TV platform is not far different to the series above.
As we know, WebOS is one of the best smart TV platforms. In 4.0 version, there are not many changes brought over the previous version. At a glance, its user interface looks similar to the previous version. But even so, there is a minor change on the top right of the screen where in this version, there is an additional quick access shortcut to search functions. On its home menu, there is still a strip bar at the bottom across screen where all of inputs, apps, menus setting shortcuts are well-organized, makes the navigation is easy. Let alone, it is equipped with excellent remote control called “LG Magic Remote” that has a lot of smart features and excellent voice navigation, this certainly makes navigation is more simple and faster. Additionally, like other smart TV platforms, it also already provides a lot of attractive preinstalled apps like YouTube, Netflix, Amazon Videos, Live TV, Games, and many more. It also has an app store called “LG Apps Store” that also provide thousands of downloadable apps, games, contents, and more.
As we have mentioned, as its controller, LG UK7000 comes with LG Magic Remote. Its remote is a bit large and have a lot of buttons. In addition basic buttons like “Number Buttons”, the number “quick access buttons, “volume buttons” and others, it also has two dedicated buttons for Amazon Videos and Netflix. This is also equipped with built-in microphone for voice navigation. With LG AI ThinQ, this makes its voice navigation can do a lot of more jobs, even not only for controlling menu and functions on your TV, but also can used to control other compatible ThinQ compatible device like Dish Washer, Air Conditioner, and others. This remote also supports CEC menu that means it can be used to control some functions of other devices connected on your LG TV via HDMI ports. And the excellence, it has a feature called “point and click”. In addition to combination of its direction pad and scroll wheel is already powerful for navigating, once you point the remote on the screen, it allows you to move the cursor on the screen by moving this remote. This certainly makes navigation is easier and quicker.
Overall, LG UK7700 is a good mid-level TV for any usage. As long as you use it in a room with normal light, overall, its picture quality is fairly good. Although its peak brightness is not so bright, but on the other hand, it can handle the reflections very well. Its good motion handling and low input lags also makes it is as a good TV for watching sports or playing games or even when used as a PC monitor. Additionally, its good side viewing angle coverage also makes it suitable for a wide room where there are viewers watch TV from multiple angles. But even so, since it cannot produce deep, it is not suitable when used in a dark room. Additionally, its limited peak brightness also makes it is not suitable for very bright room. And since its HDR performance is limited, you will not get a lot of benefits offered by HDR technology itself like more details picture in a dark scene or bright scene.
Should I buy this TV? If compared to the series above, HDR performance of LG UK7700 may be limited and picture quality offered is not also too excellent. But for its price level, what offered by it can still be said good for mixed usage, whether it is used for watching TV Shows, Sports, Movies, or playing games. Meanwhile, with more affordable price, you can still get the benefits offered by its smart TV platform and AI ThinQ as excellent as the series above it that is sold hundreds even thousands dollar more expensive. Now, the decision certainly comes back to you according to your own preference. But even so, if you often watch TV in a dark room or watch movies with a lot of dark scene, a TV with VA panel like Samsung NU8000 may be a better alternative for you.
