LG A1 OLED 2021

Cheap 60Hz OLED

OLED Panel

The LG OLED A1 is the first OLED that only has 60Hz. This may put some people off at first, but for most applications this is not an issue.

Equipped with the same chipset as the B1, content also looks excellent on this OLED, even if the brightness is slightly lower than on the more expensive models. On the negative side, the A1 lacks gaming features like HDMI2.1 and 120Hz, and it also lacks a twin tuner.

Sufficiently bright - but rather for darker environments

The LG OLED A1 and also the LG OLED B1 suffer from the biggest weakness of OLED panels: A comparatively low brightness.

But no worries, both are even suitable for well-lit living rooms with large windows! In extreme cases, reflections might occur, but the brightness is by far sufficient for a movie or a series evening.

Wide viewing angle thanks to the OLED panel

The graphic already reveals it: The viewing angle of both TVs is extremely wide. Thus, both LG OLEDs are perfectly suited for widely arranged seating areas or movie nights with the whole family.

No differences with SDR material

Due to the theoretically infinite contrast and the wide color space, both are perfectly suited for SDR content or regular TV. The 60 Hz panel does not have any disadvantages, and the brightness difference of 100 nits is so small that it does not really affect the rating. The brightness is perceived logarithmically and only about ten times the brightness appears twice as bright.

Bigger difference - but hardly noticeable

With HDR content, the differences are more noticeable, but still only marginal. The brightness is even more important for the HDR performance, but the difference is only visible in a direct comparison.

On a positive note, the cheaper LG OLED A1 also supports Dolby Vision IQ, just like the LG OLED B1. This allows the OLED to recognize how much ambient light is present, and the picture is adjusted to the conditions.

Thus, the difference is only so small that the surcharge of the B1 cannot be justified — because the difference between 60 and 120 Hz does not matter here either.

Missing twin tuner

As can be seen from the SDR and HDR image comparison, the picture quality of LG’s OLED A1 is only marginally different from LG’s OLED B1. In summary, both TVs are perfectly suited for any movies and series.

One difference that should be relevant for the fewest, but which is important to mention for thos who use it, is the missing twin tuner on the LG OLED A1.

Significant differences

The difference between these two LG OLEDs becomes clear in gaming. This is where the 120 Hz panel of the LG OLED B1 really comes into its own. Coupled with the 2 HDMI 2.1 ports, the LG OLED B1 is a gaming OLED that can fully exploit even the most demanding console. The LG OLED A1 lacks these features, which is due to the 60Hz panel.

So, if you own a next-gen console, the LG OLED B1 is recommended.

Fast action on both OLEDs

The difference between the 60Hz and 120Hz panel also comes into play for sports broadcasts, since features like the Motion Interpolation can be more effective. However, both perform excellently here as well, since the picture quality is razor-sharp and the response time of about 0.3 ms does not let any action get lost.

Again, the LG OLED A1 is not only sufficient, but also highly recommendable despite its poorer rating.

Deficits of the A1

The LG OLED A1 also has slight differences to the LG OLED B1 in terms of features, but they are not relevant for everyone. For one, the A1 lacks a twin tuner, which means that you cannot watch a show on it and record another one at the same time. It also lacks the aforementioned gaming features, which result from the missing HDMI2.1 interface and the 60 Hz panel.

Our conclusion:
Clear application differences

In the end, the decision can be made very easily: LG’s OLED A1 is recommended for all applications except for next-gen gaming, since the difference is only very slight in all other applications. However, the difference is clearly visible in gaming because the B1 also has 2 HDMI2.1 interfaces in addition to 120 Hz. Together with the Variable Refresh Rate, the B1 is an LG OLED that really delivers everything your gaming heart desires.
