The LG BX OLED is an excellent TV for most use cases, as it features deep blacks, superb reflection diffusion, HDMI 2.1 support, and VRR. However, watch out for the risk of display burn-in and low peak brightness.

The LG BX OLED TV performs exceptionally well for gaming and streaming movies/TV shows. Its OLED panel provides deep blacks, an infinite contrast ratio, excellent reflection diffusion, and wide viewing angles. In addition, gamers should especially adore the presence of HDMI 2.1 along with VRR and ALLM. But, the rare risk of permanent display burn-in is not something every user will deal with. And the low peak brightness will be a turn-off for many.



  • Experts liked the native 4K output of the LG BX OLED TV. And they also noted that the A7 Gen 3 processor inside does a commendable job upscaling lower resolution content without any upscaling artifact.


  • The LG BX OLED TV comes with really great color accuracy out of the box. And just like its higher-end counterparts (e.g., LG GX OLED and the LG CX OLED), it doesn’t crush as much black details as the older LG OLED TVs after calibration. Besides, the color volume (with a wide color gamut) of this LG OLED TV is also pretty great. It is on par (if not better) with the top-rated Budget TVs like Konka U5 Android TV in this regard.
    • However, one reviewer pointed out that the gradient handling of the 10-bit panel leaves a lot to be desired in dark scenes. And in some specific resolution and refresh rates (e.g., 1080P at 120Hz), this TV doesn’t support a chroma 4:4:4 input.


  • Critics adore the perfect black levels of the LG BX OLED TV, thanks to its organic LED display. Basically, OLED TVs can turn each pixel off to display deep and inky blacks. Because of its pixel-level dimming, it’s much better than both LCD and mini LED TVs in this area.


  • The LG BX OLED TV features a very mediocre peak brightness for a 4K TV of its caliber. RTings only managed to get 707 nits of peak brightness in a 10% window, which falls short of the 1000 nits threshold for an authenticating HDR gaming/viewing experience. The newer LG OLED TVs (e.g., the LG C1 OLED) improve significantly in this aspect.


  • Reviewers were highly impressed with the infinite contrast ratio of the LG BX Smart OLED TV. Moreover, as individual pixels emit their own light, critics noted that it’s a great TV to watch movies/TV shows in the dark.


  • The LG BX OLED TV gives up local dimming for pixel-level dimming, so we can’t comment on this aspect. However, testers noted that being an OLED TV, it doesn’t exactly need any local dimming feature as the black levels are already perfect.


  • Product experts love the LG BX OLED TV for gaming. Starting from 120Hz panel, FreeSync & NVIDIA G Sync compatibility to full-fledged HDMI 2.1 support, VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode), this OLED TV is packed to the brim with different gaming features. As a result, owners of the next-gen consoles (e.g., Xbox Series X/S, PS5) can rely on this TV for amazingly responsive gameplay. You can also check the LG C1 OLED if you want an equally better gaming TV.


  • The LG BX OLED TV supports HDR 10, HLG, and Dolby Vision. And critics noted that the HDR performance is quite decent, thanks to the wide color gamut and volume.
    • However, they also noted that the low peak brightness somewhat hinders the HDR performance. And it doesn’t support HDR 10+.


  • Expert reviewers laud the fantastic motion handling of the LG BX OLED TV. In addition, it includes an optional BFI (Black Frame Insertion) mode along with sports alert for fast-paced content. And LG’s OLED Motion Pro setting is also present for the fans of the “soap opera effect.”


  • The LG BX OLED TV has a 120Hz native refresh rate panel. And it has VRR, which ranges from 40Hz to 120Hz. So reviewers saw that the frame rate could dip as low as 40FPS before noticing the lag.


  • Testers were delighted by the near-instantaneous response time of the LG BX OLED. They also noted an input lag of just 6ms with VRR, which is excellent for gaming.
    • But, just like the Konka U5 Android TV, the fast response time can result in stuttering while playing back 24FPS content.

Viewing Angle

  • The LG BX OLED TV delivers extensively wide viewing angles and is on par with IPS LCD TVs in this regard. So critics could go as far off-center as 70 degrees before the color started to change to their eyes. Moreover, they highly recommended this OLED TV for everyone who has a big room and needs wide viewing angles.


  • All reviewers agree that the LG BX OLED TV brings the rare risk of permanent display burn-in with it. However, they felt that it wouldn’t be an issue for most users, as long as you vary the content you watch. And LG also has three built-in features (Screen Shift, Logo Luminance, and Pixel Refresher) that help mitigate this problem.



  • The LG BX OLED TV comes with a centered plastic stand that holds the TV well. It doesn’t spread as wide as the TV itself, which is excellent for placing the TV on a smaller table.
    • Top experts did note some wobble with it installed, however.


  • Testers appreciated the clip on the back of the LG BX OLED TV for cable management. In addition, they also noted a few holes on the same plastic portion (that houses the ports as well) for a VESA 300×200 wall mount. But the top half is metallic.


  • The LG BX OLED TV features skinny borders which are just 0.9cm wide. Critics said that the bezels wouldn’t distract most users, and their slimness helps give this TV a relatively modern look.


  • TV reviewers measured the maximum thickness of the LG BX OLED at just 4.8cm. So it’s incredibly slim and should stay flush to the wall when wall-mounted, according to them.



  • The LG BX OLED TV has a standard built-in HDTV tuner. Cnet noted that it supports both the ATSC and the QAM standards, and it works well within its specification.


  • Product experts hated the back positioning of the two essential HDMI ports that support HDMI 2.1 on the LG BX OLED TV, making them hard to access once wall mounted. Thus, the other two HDMI ports (HDMI 2.0) are located on the side. Besides that, this TV also sports three USB ports (USB 2.0) and an ethernet jack if you don’t use Wi-Fi.

Remote Control

  • The LG BX OLED TV includes LG’s universally praised magic remote with motion control functionalities. It works so well that it should remind veteran gamers of the Wiimote.
  • However, it lacks a backlight for better visibility in the dark.



  • Reviewers applauded the large number of apps LG’s WebOS store can deliver on the BX OLED. And most apps run smoothly on the built-in SoC.
    • But, the app library isn’t as massive as something like Android/Google TV OS. And app sideloading might be more difficult compared to other platforms.


  • The LG BX OLED TV comes with a few pre-installed streaming apps (e.g., Netflix, Prime Video, LG Channels, Disney+, etc.). Most other major streaming apps are also available on the WebOS store. And 4K HDR streaming doesn’t exhibit any lag or frame drop.


  • Critics were satisfied with the smoothness and number of extra features LG’s WebOS smart UI offers on the LG BX OLED. And it has two of the major voice assistants (Google Assistant & Alexa) built-in for easy voice navigation.



  • The LG BX OLED TV’s built-in audio system consists of two speakers and two woofers, with a total output power of 40 Watt.
    • But, the speakers distort a lot on higher volume levels.


  • Product reviewers reported the bass of the LG BX OLED TV’s built-in audio system to be decent, as it does have some punch to it and gets low enough.
    • However, they also said that bass heads need an external sound system to complement this TV because the built-in woofers don’t produce much thump or rumble.


  • The LG BX OLED can reach an extremely wide soundstage thanks to its support for Dolby Atmos over eARC. But, you do need a compatible receiver for it to work.
