Does LG's entry-level BX OLED pay off?

Our conclusion

The BX is an OLED TV by the Korean manufacturer LG and is the successor of the extremely successful OLED B9. As LG’s most affordable TV with organic LEDs, it is of course a special focus of attention, as it offers an interesting possibility for many to enter the OLED technology. But is the BX as well tuned as the B9, or have some important factors fallen by the wayside? In the following article we took a closer look at the TV.

Design of the OLED BX

The LG OLED BX has a successful design and makes an excellent impression. It looks very similar to its predecessor, the B9 and its more expensive sister model, the CX, and also has a very thin metal frame that makes a very high-quality impression. The BX is extremely flat, so it looks great when mounted on the wall. Its stand has a sleek design, but unfortunately it is made of plastic, which makes it wobble slightly when pushed. However, you should not have any problems with the TV, as it is an absolute high-end device. For a clean cable management there is an eyelet on the back of the stand, through which the cables can be bundled. Unfortunately, some interfaces are oriented to the back, which can be a bit annoying when the TV is mounted on the wall.

Excellent OLED picture quality - with one major weakness

As usual, the picture quality of the 10 bit OLED panel is really outstanding, especially in dark rooms. Due to the perfect blacks and the theoretically infinite contrast ratio, it provides a quality unattainable by conventional LED displays. In bright rooms, the picture quality is not to be sneezed at, but due to the low brightness, it is not quite as brilliant as in conventional LED displays. In addition, there is the possibly annoying Automatic Brightness Limiter, which reduces the brightness in large bright scenes in order to protect the organic LEDs from overheating. HDR content is beautifully presented due to the very wide color gamut, but suffers from the low peak brightness – since it is so low, bright highlights cannot be brought out as well.

Another big advantage of the OLED design is an extremely wide viewing angle. Even with very oblique viewing angles on the panel, the colors do not blur and the black level remains almost unchanged. With the powerful Alpha 7 Gen 3 processor, many formats are supported for image optimization. As a dynamic HDR format, the BX features HDR10+ and Dolby Vision IQ, which also adjusts the screen brightness to the surrounding brightness.

First-class motion handling

The motion handling of the LG BX OLED is outstanding. It has a panel with a refresh rate of 120Hz, which is important for a good motion handling. Its response time of 0.2ms is almost perfect, which is especially excellent for very fast content like action movies, sports or gaming, because there is almost no motion blur. This blur can be further minimized by the 120Hz Black Frame Insertion feature. The extremely low response time favors stuttering for content with a low frame rate, which can be easily corrected by the motion interpolation feature. Of course the BX can remove judder from all sources.

Everything you need for a great gaming experience!

The LG BX has everything you could wish for when it comes to gaming. It has a low input lag of ~15ms at [email protected], whereby in combination with the low response time there are hardly any delays or blurry images. Furthermore there is an Auto Low Latency Mode, which automatically detects connected consoles and keeps the TVs Input Lag as low as possible.

To ensure screen-tearing free gaming, the BX supports a variable refresh rate via G-Sync and FreeSync Premium, which supports almost all newer graphics cards – so even PC users can play without screen-tearing if they have a newer graphics card from Nvidia or AMD. Just like its predecessor, the B9, the BX is also equipped with an HDMI 2.1 interface. So together with the 120Hz panel you are well prepared for the upcoming consoles Xbox Series X and Playstation 5 and you can take it to the limit with a 4K resolution with a refresh rate of 120Hz.
The wide viewing angle, which is typical for OLEDs, is really handy for gaming with several people, because no one has the disadvantage of fading colors if they sit at an angle to the panel.

The HDMI 2.1 port of the LG BX does not support the standard 48GBit/s bandwidth, but only 40GBit/s. This is not a noticeable difference as 40 GBit/s is also sufficient for 4K @ 120Hz 4:4:4

Sound of the BX

The BX has been equipped with a 2.2 channel 40W sound system, which is well tuned in the trebles and midranges, allowing for a clear reproduction of dialogues. However, as with most other sound systems integrated into televisions, the BX’s bass is not strong enough to create a real atmosphere in action-packed content such as action movies or games. The speakers do get loud enough to allow the BX to be used in noisy surroundings, but as the volume increases, distortions become more audible – which should not really be noticeable at normal volume. If you buy a TV in this price range, you will probably not be satisfied with the integrated speakers. If you want to expand your setup with an external sound system or soundbar, the BX has an HDMI eARC interface, which supports uncompressed Dolby Atmos via Dolby True HD. This allows a rich, spatial sound from all directions, giving you a true cinema feeling. Throughout its 2020 lineup, LG has eliminated DTS support, which is also the case with many other manufacturers, such as Samsung.

A really smart television

The BX uses the WebOS 5.0 as its smart operating system, which can be controlled with the Magic Remote. This allows a cursor to be controlled by hand movements to navigate smoothly through the menus and apps. However, a classic navigation using arrow keys on the remote control is also possible, depending on your preferences. If both types of navigation are too cumbersome for you, you can use the voice control via Amazon Alexa or the Google Assistant instead. For wireless data transfer between the TV and Apple devices Airplay 2 available.

The choice of apps is huge and classics like Netflix, Amazon Prime Video and Youtube are already pre-installed. With LG ThinQ, smart home applications can be controlled from the BX and everything is conveniently displayed on a dashboard. There is also a Twin Tuner, which enables Time Shift and PVR.

Good OLED TV with a big weakness

With the LG BX OLED, you have an excellent TV for almost any content and one of the most affordable OLEDs. Its picture quality in dark surroundings is almost impressive due to the perfect black and the theoretically infinite contrast ratio – so it is in no way inferior to the other OLEDs here. It also has an extremely wide viewing angle, so that the colors appear vivid and well saturated even from very oblique angles. Unfortunately, the BX does not become very bright even for an OLED. Therefore, it is not really suitable in brighter surrounding and it also cannot display HDR content very well. Apart from that it is a future-proof TV that will satisfy most users. Due to the HDMI 2.1 interface and the outstanding motion handling it is also an ideal choice for the upcoming consoles as it can already take them to the limit with [email protected]

Alternatives to the LG OLED BX

LG OLED B9
Predecessor

The LG OLED B9 and the LG OLED BX are two very similar televisions – which becomes obvious by the almost identical design. However, the brightness of the B9 is slightly higher, resulting in a better picture quality in bright rooms. In addition, the higher peak brightness means that HDR content can be displayed better and bright highlights can be presented more effectively. The BX also supports the variable refresh rate via FreeSync Premium and the Black Frame Insertion feature at 120Hz, which allows it to reduce motion blur even in 120Hz content. Otherwise, the two OLEDs are nearly identical in construction.

LG CX OLED
The more expensive sister model

Compared to the next lower priced OLED TV, the LG OLED CX is ahead. Although the two models are very similar, the CX has the advantage of producing a higher brightness. This allows the CX to produce better picture quality in brighter surroundings, and the higher peak brightness makes HDR content look better. In addition, the integrated Alpha 9 Gen 3 processor is more powerful and the CX makes a higher quality impression, as the stand and frame are made of metal.

Samsung Q90T QLED
OLED vs QLED

In direct comparison with Samsung’s 4K QLED flagship, the LG BX OLED has a hard time. Due to the OLED design it has a better picture quality in dark surroundings and also a better motion handling, because its response time of less than 1ms is unattainable for other types of TVs. But the Q90T is far superior in brighter rooms. With its higher brightness and equally excellent reflection handling, its picture quality in bright rooms is truly impressive, making it unrivalled in this category. In addition, it does not require the potentially annoying Automatic Brightness Limiter, so there is no need to dim the brightness in large bright scenes. The higher peak brightness also allows it to display HDR content brilliantly, which the BX is not quite capable of. In return, the OLED supports Dolby Vision, which enables it to dynamically optimize HDR content. In the gaming category the two TVs are equal, even though the Q90T has the better input lag with about 10ms at [email protected]
