What You'll Learn
LG B7's screen is plastic, not glass
The LG B7 is an OLED 4K TV that was released in 2017. It has a simple and minimalist design, with a thin screen and borders. The B7's screen finish is reflective and it gets bright enough to be used in most environments.
Despite what LG's marketing and specifications might suggest, the LG B7's screen is made of plastic, not glass. The picture-on-glass design means that the plastic screen is mounted on a glass backing. This is similar to placing a piece of paper on a sheet of glass; the paper (or in this case, the screen) is still made of paper, even though it is stuck to glass.
This distinction is important because it has led to confusion among customers, with many believing that the screen is made of glass. While the glass frame is an attractive feature, it is the plastic screen that is the key component.
The plastic screen on the LG B7 is a common feature across all LG OLED models. From the B7 all the way through to the W7, all LG OLED screens are plastic. This is an important clarification for consumers, as it affects the performance and durability of the TV.
In summary, the LG B7's screen is plastic, not glass. This plastic screen is mounted on a glass backing, which has led to some confusion among customers. It is important to understand the difference between the screen and the frame, as they have different properties and impacts on the TV's performance.

LG B7's design
The LG B7 is a high-end 4K OLED smart TV with excellent picture quality. It is one of the most affordable OLEDs on the market, offering impressive performance without the hefty price tag. The B7A variant comes with LG's Magic Remote, which has a useful onscreen cursor feature and a microphone for voice search.
The B7 has a sleek and impressive design, with a very thin screen and thin borders. The TV sits on a stand similar to the B6 model, which has a small footprint and a clear support that looks good and feels stable. The B7 does not have a front-facing soundbar, and its rear-facing inputs may be difficult to access if the TV is mounted close to a wall. However, it does have two HDMI and two USB ports on the side that are easily accessible.
The LG B7's OLED panel offers infinite contrast and a wide viewing angle, with perfect blacks and impressive HDR image quality. The TV produces little motion blur and can reproduce a wide gamut of colours, although the colours are not as vivid as on some other sets. The B7 is excellent for watching movies in a dark room, but it is prone to temporary image retention and permanent burn-in.
The LG B7's screen is made of plastic, which is mounted on a glass backing. This design has caused some confusion among customers, as LG's marketing and the "picture-on-glass" description may lead some to believe that the screen itself is made of glass. However, all LG OLED screens are made of plastic.

LG B7's performance compared to other TVs
The LG B7 is a high-end 4K OLED TV with excellent picture quality, infinite contrast ratio, and a wide viewing angle. Its ability to produce minimal motion blur and a wide gamut of colours, along with its high peak brightness, makes it a great choice for watching movies in dark rooms. The TV's standard dynamic range (SDR) colour performance is near-perfect, and its perfect black levels and stunning colour reproduction create an impressive HDR image. The LG B7 is a fantastic option for mixed usage, offering a well-rounded set of features at a reasonable price.
However, the LG B7 is not without its flaws. It tends to retain static images temporarily and is not as bright as some LCD TVs. Additionally, it falls short of hitting the "expanded colour" gamut points of higher-end models like the LG C7 Series. The LG B7 also lacks eARC support, which can be a drawback for those seeking to pass through higher-quality audio.
When compared to other TVs, the LG B7 holds its own. It offers similar performance to the B7P available at warehouse stores like Costco and Sam's Club. The LG B7A, a similar model, has marginally better input lag in HDR gaming and slightly better viewing angles, although both TVs excel in these areas. The LG B8, a newer model, surpasses the LG B7A with improved motion handling due to its black frame insertion (BFI) feature, making it a better choice for gamers.
The LG B7's performance is also comparable to the German B7T and the LG E7. The E7 features a dedicated soundbar for enhanced sound performance and improved temporary image retention. However, the main difference between the LG B7 and the E7 is the presence of a glass frame on the E7, which has led to confusion among consumers regarding the screen material.
In summary, the LG B7 is a fantastic entry-level OLED TV that delivers exceptional picture quality and performance. While it may not surpass every aspect of higher-end models, it offers a well-rounded package at a competitive price point. As a 2017 model, some users have considered upgrading to newer models, citing concerns with near-black detail in HDR and the lack of eARC support. However, the LG B7 remains a solid choice for anyone seeking a high-quality viewing experience.

LG B7's suitability for gaming
The LG B7 is a high-end 4K OLED TV with a range of features that make it suitable for gaming. Firstly, it has a very responsive display with a low input lag of 21.4ms in game mode, which is one of the lowest figures measured for a TV. This low input lag means that the TV is very responsive and has minimal delay, making it ideal for gaming. The TV also has a low amount of motion blur, which enhances the smooth and fluid appearance of fast-moving objects on the screen, such as in video games.
The LG B7's OLED panel can produce perfect blacks and an infinite contrast ratio, resulting in exceptional picture quality. This is further improved by the TV's ability to reproduce a wide gamut of colours and achieve a relatively high peak brightness, creating an impressive HDR image. The HDR feature is particularly significant for gaming, as it enhances the visual experience. Additionally, the TV's wide viewing angle allows for comfortable viewing from various positions, making it suitable for gaming with friends.
The LG B7 also has some drawbacks that should be considered. Firstly, it may not be as bright as some LCD TVs, and it tends to retain a ghost of static images temporarily. The TV also lacks a dual tuner in Europe, and its remote control has been described as cheap-looking and cluttered.
Despite these minor drawbacks, the LG B7 is a well-rounded TV that is suitable for gaming. Its exceptional picture quality, low input lag, and smooth display make it a great choice for an immersive gaming experience. Additionally, its ability to handle motion well and produce perfect blacks makes it a good option for gaming in dark rooms or watching sports.

LG B7's suitability for watching sports
The LG B7 is a great TV for watching sports. The B7's OLED screen displays very uniform colours, so grassy football fields don't have any banding or blotches. It also handles motion very well, making fast-moving players look fluid. The B7's ability to shut off individual pixels gives it perfectly uniform blacks and an infinite contrast ratio. The TV's accuracy with colours within its gamut could be better, as almost all points artificially undershoot their targets and saturated cyan turns green. However, the B7's screen finish takes good care of reflections, and it gets just bright enough not to appear dim in most environments.
The B7 has a great viewing angle, far better than most LED TVs, and is an excellent choice for a room where people often sit to the side of the TV and view it at an angle. Blacks remain perfectly black, and the brightness decreases only slowly at an angle, though colours do degrade more quickly. The B7's grey uniformity is great, and it has slightly better viewing angles than the LG B7A to accommodate those viewing from the side.
The B7 is LG's most affordable 2017 OLED TV and features everything you would expect from a modern TV, including 4K and Dolby Vision. It also has a low input lag and a low amount of motion blur, which is great for gaming.
The B7's screen is made of plastic.
