LG E7P OLED 55" (OLED55E7P) vs Samsung NU7100 40" (UN40NU7100)

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

From games to movies, sports and use as a PC monitor, the NU7100 is a good TV for diverse usage. The balance of low input lag, good picture quality, and decent motion handling make sure of it.

Even though the NU7100 doesn’t have local dimming, watching TV in the dark is not a problem due to amazing black uniformity - the blacks are even and there are no clouding issues.

Contrast is remarkable too – blacks are deep, and whites are bright.

The TV is a great option for a PC monitor. Not only does the NU7100 have ideal low input lag thanks to the “_PC_” and “Game” modes, it also features support for most resolutions, except 1440p.

Another thing to note – Samsung’s app store has the Steam Link app, which lets you connect your PC to your TV and play games without needing to connect the Steam Link hardware.

When you first turn on the TV, it basically walks you through the setup process and you can start properly using it in a matter of minutes.

Regarding picture quality, it’s also quite reasonable right out of the box. White balance (gray color inaccuracy) and color dE (color inaccuracy) could be tweaked down for better quality, but most people won’t notice a sizeable difference.

In case you can’t figure something out when setting up, the TV also has a handy “e-manual” button.

The NU7100 has a smooth, fast, and easy-to-navigate interface with a lot of room for customization, so you can tailor it for easier access to your most-used apps.

Samsung’s app store has a huge and diverse app library, second only to the Google Play Store.

The SmartThings app allows the user to control the TV and other connected devices via their smartphone.
