Battle of the high-end models for the crown
Anyone interested in screen technologies and UHD televisions will not be able to avoid OLEDs. This stands for organic light emitting diode, or organic light emitting diode. This term originates from organic chemistry. Unlike LCDLCD = Liquid Crystal Display – a type of screen using liquid crystals for creating the image screens, which need a backlight to create an image, organic light emitting diodes simply emit the light themselves. Each pixel is a diode.
This means that all colors can be generated and excellent images can be displayed. OLEDs are also known for the best black level. Unlike other technologies, however, they do not “produce” black – the diode is simply off. In addition, the viewing angle is excellent: colors do not get paler or less impressive even from the side.
Notorious is also the risk of a burn-in: This is the “burning in” of a single pixel, which then can no longer change its color and is permanently noticeable. However, various expert platforms have proven that this risk is virtually non-existent for normal users.
Here the LG CX was chosen as the winner because it has the best all-round performance. But the other two TVs are also outstanding TVs that have their very own special features.

The LG CX also offers perfect black levels, an excellent contrast ratio and a very wide viewing angle thanks to OLED technology. The processing and design of the CX are also extremely high-quality and impressive. However, what distinguishes it from the two alternatives are its gaming features and the integrated HDMI 2.1 interface.
Due to the HDMI 2.1 Interface the OLED is a really future-proof TV. This is the only way to enable the large data transfers (up to 40 Gbit/s) that will be needed in the future for top performance of the upcoming Playstation 5 and Xbox Series X. Also available are VRRVariable Refresh Rate – synchronizes the display’s refresh rate with the output refresh rate of the graphics card (FreeSync, G-Sync, HDMI Forum) to enable gaming without tearing, as well as the Auto Low Latency Mode (ALLM), which automatically reduces the latency between input device and output device to a minimum.
Since the CX supports Dolby VisionDynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits IQ, HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) content is optimized and even adjusted to the brightness of the environment. This allows it to produce a more attractive image in bright surroundings, where OLEDs have greater problems due to lower brightness.
Smart features are also very good on the LG CX. Google Assistant and Amazon Alexa are on board for voice control. Streaming and mirroring from cell phone or tablet is possible via Apple AirPlay 2. The CX is available in 4 sizes, 48, 55, 65 and 77 inches.

Alternatives to the LG CX OLED as OLED TV
The Sony A8H is an OLED from the 2020 Sony lineup. Thanks to the OLED technology, the A8H offers some unsurpassable advantages that only a real OLED TV can provide: perfect black, extremely high contrast and an extremely wide viewing angle. If wall mounting is desired, the A8H also scores with its minimal depth. On the wall it protrudes only a few millimeters. To refine the sound, a soundbar can easily be mounted underneath the TV.
However, if you follow Sony’s advice, you can integrate the A8H into your hi-fi system. Using an AV receiver and two satellite speakers on either side, the A8H acts as a center speaker and the sound comes directly from the center of the TV.
It is well suited for occasional gaming without great demands, but the competition can do better. There is no HDMI 2.1, no VRR due to FreeSync and no Auto Low Latency Mode.
The Sony A8H is best suited for home cinema fans who are looking for a powerful picture and sound solution for their home system. Here you can get Dolby Vision and Dolby Atmos as well as DTS:X. It is available in 55 and 65 inch.
If the LG CX is a bit too expensive for you, but you’re still looking for an OLED TV that has excellent picture quality and all the gaming features you could need, then the slightly slimmed down LG BX is definitely an alternative. It is also equipped with an HDMI 2.1 interface and is therefore also extremely future-proof.
The difference to the CX is not so big. The CX gets a little brighter, has four instead of two HDMI 2.1 interfaces and a more powerful processor, which allows an improved image processing. But the brilliant OLED picture quality is still available with the LG BX.
It also has perfect blacks and the theoretically infinite contrast ratio like other OLED TVs – but the main difference lays in the price. The BX is one of the most affordable 2020 OLED TVs.
For a more detailed comparison we have created a separate article and in a video we go into the most important differences.
