The B7A is excellent for gaming thanks to its really low input lag and near-perfect pixel response time that gives it virtually no motion blur.
It’s perfect for all types of games, even fast-paced action games. The experience will be really responsive and fluid. Players will have no issues keeping their actions in sync with what’s on the display thanks to the really low input lag of ~20ms, and fast-moving objects won’t leave any trails on the screen because the panel has a response time of ~1.0ms - it can fully change its pixels color in that tiny amount of time.
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. This usually happens with content that has a static image anywhere on the screen, like the logo of TV channels.
As the B7A has an OLED panel, it unfortunately suffers from this problem. There might be some retainment of artifacts for ~15 minutes when this happens, and it usually goes away after watching other content without static images.
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. Fortunately, the B7A has a “Pixel Refresher” feature that can recalibrate the screen, which should get rid of any remaining artifacts.
The B7A's picture quality is top-of-the-line. It has an OLED panel that gives it infinite contrast ratio, excellent screen uniformity, high peak brightness, wide viewing angle, and great handling of reflections.
Thanks to that, it can reproduce blacks perfectly and the uniformity is top-notch - they’re truly dark and even, because the OLED panel has the ability to manipulate pixels individually.
Colors really shine and look true-to-life, thanks to the peak brightness levels peak of ~400 nits for SDR & ~700 nits for HDR.
The picture quality also doesn't suffer from much deterioration when viewed from any angle because the panel has a really wide viewing angle. It’s also capable of maintaining the same picture quality in bright environments, thanks to its high peak brightness levels and great handling of reflections.
The sound quality of the B7A's built-in speakers is below average. It can't get very loud with the max volume peaking at ~85db, and sound quality it offers does not match the picture quality.
The B7A can reproduce a really broad range of colors that are crucial for HDR, which also means it has zero issues with SDR colors.
It’s capable of reproducing ~70% of the standard colors for 4K HDR, the Rec. 2020 colorspace. This is one of the highest in the 4K TVs market.
It can also display these colors at different brightness levels accurately that conveys much more HDR details than its direct competitors can.
The B7A runs on the webOS smart platform, known for its intuitive and fully customizable UI. It’s 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 B7A can display extremely fast-moving objects smoothly without any blur or lag, thanks to its OLED panel that has near-perfect pixel response time of ~1.0ms.
The B7A 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.
The B7A is the perfect choice for HDR content. On top of its exceptional picture quality with perfectly deep blacks, it has everything essential to an excellent HDR experience: an OLED panel, wide color gamut, and high peak HDR brightness levels.
Shadow details are perfect and highlights are really stunning, making for an immersive experience. The OLED panel can manipulate pixels individually, which means it has control over every tiny bit of the picture.
The panel can also reproduce the colors necessary for true HDR, and these colors will really pop thanks to its high peak brightness level of ~700 nits.
The B7A looks good from almost any angle thanks to its OLED panel, making it a great choice if you usually watch the TV with large groups of people.
Its viewing angle is wide enough for a group of audience to experience more or less similar picture quality when watching from multiple angles off the center of the screen. The black levels and brightness only starts degrading at ≥75°, which means the picture quality will stay roughly the same no matter which angle the screen is viewed from.
The B7A comes with LG's Magic Remote, touted for its easy-to-use design.
It works similarly to a Nintendo Wii remote where the on-screen cursor follows the remote's movement, making it easy to navigate the UI and select menu items.
The remote also has a built-in microphone for the voice command feature, which also supports content searching with voice input.
The B7A can display clear and crisp images from a computer thanks to its full 4:4:4 color support. Because of this, text or shapes with clear, hard edges won’t be blurry.
Apart from games, the B7A is great for movies and sports. Its top-notch picture quality, combined with the features it offers, makes it perform really well across different kinds of use cases.
Movies look excellent thanks to the exceptional picture quality, and it’s also a great pick for watching sports because the motion blur is non-existent and the panel is really uniform.
It has near-perfect pixel response time of ~1.0ms, resulting in virtually no motion blur, so fast-moving objects like football don’t leave any trails on the screen. The panel is also uniform enough that it has no issues with displaying large, same-color objects on screen, like football fields.
While the B7A can seem rather expensive, the picture quality and features it offers is top-of-the-line and can’t be beaten. The performance easily outclasses all other TVs in this price bracket.
The B7A's interface includes ads that can’t be removed - there’s no option to disable it. Ads on this TV can be really annoying when compared to other smart TVs because they're almost everywhere. There are video ads in LG's Content Store, apps menu, and even voice search results.
Out of the box, the B7A’s white balance might look slightly off to some viewer, so a brief calibration might be required if you notice it. Fortunately, all the optimal color settings are available on the internet and isn’t hard to find.
The Samsung Q8C offers smooth and lag-free gaming experience because of its low input lag and well-managed motion blur.
The input lag of the Q8C is 23.6 ms, which means that it takes less than 1/40th of a second for a TV to react to the input from an external source like a click of a button. In terms of input lag, the Samsung Q8C is on par with its closest competitors, including the LG seven series OLED TVs.
The panel has a full pixel response time of 10.7 ms, ensuring that it takes less than 1/100th of a second for its pixels to change their color; thus, even fast-moving objects won’t leave trails on the screen. As a result, the TV has almost negligible motion blur.
The maximum viewing angle of this TV is 14 degrees, making it useless for group watching, as those who view the TV from the sides will see degraded colors and shadows.
The TV is fully compatible with all the current generation gaming consoles, including the Xbox One X, PS4 Pro, and Wii U. The Q8C also supports HDR gaming, which will allow you to experience the full range of HDR effects in the latest console games, like Hitman, NBA 2K17, Final Fantasy XV, Deus Ex: Mankind Divided and World of Tanks.
Picture-wise, the Samsung Q8C has everything necessary to provide excellent quality.
The TV can reproduce eye-catching bright scenes; especially in HDR mode, where it can sustain up to 700 nits of brightness making its colors look genuinely crisp and vivid. In SDR mode, however, the sustained luminosity drops to 400 nits, which is still higher than what the competitors in the price range of the Q8C offer.
As for dark scenes, the Samsung Q8C has it all sorted as its panel has a relatively high native contrast ratio of 4761:1, combined with well-uniformed blacks; which allows for deep scenes with noticeable brightness shifts among multiple regions of the screen.
Unfortunately, the curved panel of the Samsung Q8C looks good only from a single spot, which is located at the center of a circle made by the curve. If you need a TV that is suitable for group watching, this might not be the right option for you.
The Samsung Q8C comes with an eye-catching remote. The remote is made from metal and has a shiny metal finish. Apart from being stylish, the remote offers some extended functionality, like a microphone and voice control.
Samsung Q8C comes with the One Connect box which moves all the hard-to-access rear inputs away from the TV. This way, you’ll always have full access to all inputs and outputs of the TV even if it’s mounted on a wall. Additionally, the One Connect box can be used as a USB charging hub.
It's an excellent choice for bright rooms with lots of windows because of the TV’s ability to handle reflections, which is achieved by the aid of the TV’s glossy screen finish and anti-reflective coating.
Unlike the OLED TVs, it does not suffer from any image retention so you can leave the TV on for long periods without having to worry about pixel damage.
The Samsung Q8C is an excellent option for sports fans as the TV can display fast and dynamic content very clearly. The clear representation of dynamic content is achieved by the TV’s rapid pixel response time of 10.7 ms which almost eliminates the motion-blur effect. As the pixels can change their colors in nearly 1/100th of a second, fast-moving objects don't leave trails.
Additionally, the Samsung Q8C is especially good for watching outdoor sports, like football, rugby or golf, because the TV has high color uniformity which makes sports fields look more even and consistent.
The Samsung Q8C is more than capable of handling HDR content because of the TV’s wide color gamut, high HDR peak brightness, good native contrast ratio, and uniform blacks.
The main feature of the Samsung Q8C is its curved panel which can give you an immersive feeling of being surrounded by the TV. However, if you are not a fan of curved TVs, there is a flat, equally priced version of the Samsung Q8C simply called the Samsung Q8.
The Samsung Q8C comes with a massive 75-inch LED panel. The panel has around 2400 square-inches of viewable area, which is a third more than what the 65-inch competitors offer.
