Pro Good for gaming
The S517 is fit for all gamers because it offers a clear, lag-free experience. The TV is very responsive - it has struck a good balance between decent refresh rate, solid input lag, and good response time.
The TV is an ideal choice for console gaming in terms of its native refresh rate. It caps at 60Hz, which is perfect since most games won't benefit from anything higher than this.
The S517 is fast. An action shows on the screen in around 18 miliseconds, which can make the difference between managing to get a frag or waiting for a respawn. The time doesn't substantially increase when gaming in HDR or 4K either - it goes up to roughly 20.5 ms. The only thing to remember is to keep "Game" mode enabled for the lowest possible input lag.
The TCL S517 also handles motion and fast-paced content quite well, it has a good response time. This makes sure you can keep up with fast-moving objects and a lot of action without it all appearing blurry. A full pixel color transition takes only 15.8 ms.
Pro Functional mobile app
The mobile remote app for both iOS or Android can fully and comfortably substitute the real remote – launch apps, input text in apps, control most TV settings, etc.
Also, colors can easily be adjusted close to perfection thanks to the app’s calibration menu.
Pro Great smart features
The S517 comes with the Roku TV smart platform, which provides a comfortable interface and a big app selection.
The interface is quite basic and easy to overlook. It’s smooth and simple to swap to your favorite apps.
Roku TV offers a huge app store with all the most popular apps – Netflix, YouTube, Hulu Plus, Amazon Instant, HBO Go, Vudu and much more. Some apps are even absent from other TV manufacturers Smart TV platforms and unique to Roku.
Pro Well calibrated out-of-the-box
The picture quality when you first open the TV up is quite decent. The only settings that could potentially require tweaking are grey inaccuracy and color inaccuracy. Either way, these are things that most people won't even notice.
Pro Decent for use as a PC monitor
The S517 offers a pleasant PC monitor experience not only due to the good responsiveness, but also because of the video signal's compression.
The TV won't make text appear blurry while connected to a PC because the signal has no compression and transports color data and luminance fully. This is also known as chroma 4:4:4, and the “Computer” and “Game” modes display it properly at 60Hz.
Pro Accessible inputs
All of the inputs are conveniently placed on the side of the S517, so you won't have to worry about leaving space between a wall and the TV.
Pro Optional video smoothing feature
The S517 offers the possibility to make movement in videos smoother, also known as the "soap opera effect". This is done by making the TV take two frames and try to guess what would a frame in between of those look like, also known as motion interpolation. The frame rate can interpolate up to 60 frames per second.
Pro Handles 4K scaling well
The S517 does a reasonably good job with upscaling most content to 4K quality, be it 480p DVDs, HDTV or full HD Blu-rays.
Pro A well-rounded option
The TCL S517 is a decent option for pretty much everything, be it gaming, movies, sports, or HDR content. It has noteworthy picture quality, good all-around responsiveness, decent smart features, nice motion handling, and, most importantly, a great price.
Pro HDR playback
The S517 is a much better fit for HDR content and HDR gaming than its competitors due to the wide color gamut, decent color depth, and high contrast.
The TV can display a lot more colors than its similarly-priced counterparts. The coverage of the Digital Cinema P3 color space is very good - 90%.
The color depth is on par with competing options. The S517 has 10-bit color depth, which means that it can display approximately 1.07 billion colors in total. This is important for HDR content because HDR media takes advantage of 10-bit.
The S517 can display deep blacks in the HDR mode because of it's high native contrast ratio of 6000:1, which is easily one of the best in the given price range.
The TV can also play all HDR content, because it supports both standard formats of HDR - HDR10 and Dolby Vision. They enhance the viewing experience by editing the metadata, that is, the extra information that tells the TV how to display HDR. The formats differ in the way they deal with it however - Dolby Vision edits the picture on a per scene basis, whereas HDR10 edits everything at the start of the video.
Pro Exceptional picture quality
The LG E7P has exceptional picture quality thanks to its OLED panel, which are unrivaled in picture quality — OLED panels are capable of reproducing absolute blacks and whites on a per-pixel basis, giving it infinite contrast ratio (which may sound hyperbolic but is absolutely true).
Pro Great color reproduction
The color gamut of a TV refers to the range of colors the display can reproduce — the wider the color gamut, the more colors it can display, and the better the overall picture quality will be. This is extremely important for HDR content because it requires a much wider color gamut than SDR content. The LG E7P has a wide color gamut and have no issues with accurately reproducing the colors necessary for true HDR.
Pro Comes with an integrated soundbar
The LG E7 has an built-in soundbar that performs surprisingly well. The frequency response is noticeably better than all other TVs out there, with good extension into the lower-ends of the frequency range, which means it can produce deep bass. The distortion levels are also low and not noticeable unless the volume is set to near-maximum. While an external audio set-up will definitely be better, this soundbar will suffice for most users that doesn't wish to spend additional money on an audio set-up.
Pro Great performance for sports & gaming
The LG E7P's versatility is top-notch. The motion blur (sub-1ms) makes it an excellent choice for sports & gaming, and the low input lag (~21ms) contributes to this especially for gaming where input lag matters.
Pro Interface is intuitive and user-friendly
The LG E7P runs on the webOS smart platform, renown for its intuitive and fully customizable UI built around a Launch Bar that provides quick and easy access to the TV's apps, settings, and inputs. This can be customized and re-organized to the user's liking.
Pro Wide viewing angle
The picture quality of the LG E7P does not suffer from much deterioration when viewed from other angles. While the colors might look off as brightness decreases with the viewing angle, the black levels and uniformity remain the same throughout, thus the panel retains most of its usual picture quality. This TV is a great choice if you require wider than usual viewing angles that LED panels can't provide.
Pro Remote is well-designed
The LG E7P's remote works similar to LG's Magic Remote (included in other LG TVs, e.g. the B7A). It is noticeably bigger than most remotes, but also comes with better controls and the on-screen cursor can follow the remote's movement similar to a Nintendo Wii remote, making it easy to navigate the UI and select menu items. It also has a built-in microphone for the voice command feature, which also supports content searching with voice input.
Pro Smart platform has great ecosystem of apps
The LG E7P runs on the webOS smart platform. It has a great ecosystem of apps, ranging from media streaming services (Netflix, Amazon, YouTube, etc.) to third-party apps. Support for these apps are also first-class with up-to-date features and good performance; for instance, the YouTube app supports 360-degree video playback.
Pro Supports both HDR10 and Dolby Vision
There are two different formats for HDR — HDR10 and Dolby Vision. Some TVs support only HDR10 and can't play Dolby Vision content. The LG E7P supports both HDR10 and Dolby Vision, giving it the ability to play any HDR content in 2017.
Pro Dark scenes are perfectly reproduced
The LG E7P can handle dark scenes very well thanks to its OLED panel, which gives it infinite contrast ratios. This gives it the ability to reproduce dark scenes perfectly.
Pro Great at handling reflections
The LG E7P's panel has a glossy finish with anti-reflective coating, giving it the ability to fight light in bright environments very well. As a result of this, the picture quality remains the same even in bright rooms.
Pro Great at handling low-res content
The LG E7P is great at upscaling lower-res content such as DVDs — all details are preserved, but there are some visible haloing especially around edges.
Pro Excellent for dark rooms
The LG E7P performs exceptionally well in dark environments. Its ability to produce absolute and perfect blacks means the reproduction of dark highlights and scenes in movies will look great — this is further improved when there's no light around the TV as it allows the blacks to stand out more. This makes it great for watching all sorts of movies in a cinema-like setting, particularly movies with many black highlights/scenes where this is immediately noticeable even to undiscerning viewers (e.g. Interstellar).
Pro Extremely low motion blur
Because the LG E7P has an OLED panel, it has near-perfect pixel response time; the motion blur is virtually non-existent at sub-1ms, which means this TV will have no issues with displaying extremely fast-moving objects — they will look smooth without any blur or lag.
Pro Perfect TV for movies and HDR content
The LG E7P is a 4K OLED TV with perfectly uniform blacks and infinite contrast ratio, achieved by its ability to manipulate pixels individually. This, along with its color uniformity and wide color gamut, gives it exceptional picture quality and makes it the perfect choice for movies. It also has no issues with brightness levels as the panel can reach up to ~700 nits of brightness when playing HDR content, and it handles reflections very well.
Con Can't overcome glare
The S517 is better fit for dim environments or dark room viewing, since the brightness can’t peak very high, only at 277 nits. This is common for TVs in this price range.
Con Runs ads
The main interface page contains big advertisements that can’t be disabled.
There’s also a “Featured” tab that promotes all kinds of apps and channels.
Con Some dirty screen effect is present
This might cause some discomfort to sports fans because the playing surface might look darker at points. The S517's gray uniformity is decent at best, which, unfortunately, is often the case for lower-end TVs. The image is a little darker around the edges and the middle of the TV. The standard deviation of sits at around 3.1%.
Con Inconvenient calibration access
The only way to access the calibration menu is via the mobile app. This might be uncomfortable for people without smartphones or for people who prefer all control on the real remote.
Con HDR content lacks brightness
Small bright details in dark scenes won’t stand out. Unfortunately, this is usually the case with TVs in this price range. The TV's brightness for HDR media peaks at only 273 nits. Moreover, the TV doesn't support local dimming, which is also a big drawback for HDR content.
Con Struggles with reflections
While the S517 is okay for dimmer environments, the weakness shows in bright rooms and especially rooms with the light source facing the TV. The reflection handling of the TV is a bit worse than that of its competitors. It reflects approximately 6% of light off the screen.
Con Bad viewing angle
The S517 is a bad choice for a wide room because colors and blacks shift when viewed even slightly off center.
Basically, leaning sideward just a little bit will drastically alter what you see. Colors shift at 18 degrees, brightness shifts at 28 degrees, but the blacks shift at the extremely tiny angle of 9 degrees.
Con Suffers from image retention issues
The main drawback of OLED panels are image retention issues with static images — pixels on the panel gets burned in when the picture doesn't change for extended periods of time. Noteworthily, the static image doesn't have to be whole like a full wallpaper on the TV; it can happen with content that has a static image anywhere on the screen (e.g. the logo of some TV channels).
As the LG E7P has an OLED panel, it, unfortunately, suffers from this problem. There might be some retainment of artifacts for ~10 minutes when this happens, and it usually goes away after watching other content without static images. It's worth noting that the E7P handles this better than most OLED panels where artifacts can take longer to go away. There are some cases where normal content won't cut it, which usually happens when the static image has been there for more than some hours.
This can be remedied with the LG E7P's “Pixel Refresher” feature — it recalibrates the screen, which should get rid of any remaining artifacts. Note that this procedure takes around an hour, and the TV has to be turned off the entire time for it to work properly.
Con Interface has ads
The user interface of modern smart TVs can include some advertisements similar to those on the internet or in a mobile app. The LG E7P's interface includes ads that can’t be removed — there is no option to disable or opt-out from it. Compared to other smart TVs (e.g. Samsung's), ads on this TV can be really annoying because they're almost everywhere: video ads in LG's Content Store, apps menu, and even voice search results.
