LG OLED C9 It is no secret that the LG C9 is one of the best TVs of 2019. The OLED panelThe panel is the actual screen of a television. There is different types of panels like OLED, LCD or Micro LED and different sub-types of LCD like VA or IPS. provides perfect blacks, a theoretically infinite contrast ratio and a very wide viewing angle. The C9 gets a touch brighter than the CX and also the viewing angle is a slightly wider - but these two advantages will probably be very difficult or impossible to see in normal use. Both OLEDs are equipped with a HDMI 2.1 interface, but the CX has a lower bandwidth of 40 GBit/s instead of the 48 GBit/s that its predecessor has. This does not make any difference as no TV can use the whole bandwidth anyway. | LG CX OLED The LG CX does not differ from its predecessor in terms of picture quality. Due to the OLED construction it has an equally excellent picture and there is no real difference. However, the CX has the Black Frame Insertion feature at 120Hz. This allows a reduction of the already very slight motion blur even at a refresh rateHertz is the derived SI-unit of frequency with 1Hz=1/s - When talking about TVs this means how many different pictures a TV can display in one second. of 120Hz. The CX's built-in speakers are slightly better and the sound is a little rounder - but there's no DTS anymore. But besides the new Alpha 9 Gen 3 image processor, which is now also supposed to optimize the sound. The CX also supports Dolby VisionDynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits IQ, which allows the brightness of HDRHigh Dynamic Range - image/video with more dynamic range (contrast range) content to be automatically adjusted to the ambient brightness. In addition to 55, 65 and 77 inches, the CX is also available in a 48 inch version. |

Our conclusion: LG C9 vs LG CX - Two very similar OLEDs with slightly different features
The two OLEDs are very similar . Thus similarly even that only small but fine differences can be weighed with the purchase. In any case it is clear that the CX and C9 are both high end models, which have an almost identical picture quality – just like most other 2020 OLEDs.
Hence, only the features differ slightly. The CX has the Black Frame Insertion feature at 120Hz, Dolby VisionDynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits IQ and better integrated speakers. In return, the HDMI 2.1 interface of the C9 has a wider bandwidth – which really does not make a difference until now. Whoever can do without the additional features of the CX, or already owns a sound system can also purchase the C9, because in the end you get excellent picture quality from both devices, which can hardly be criticized. Only in very bright rooms both TVs do not perform quite as well, but neither TV has a real advantage in this field. Whoever is looking for a TV which performs well in a very bright environment can also consider Samsung’s Q90T.
For a great gaming experience, both TVs are great and there is no way to really pick a winner. The Black Frame Insertion feature at 120Hz of the CX can reduce the motion blur a little more, but otherwise the two OLEDs are equal – and due to the wide viewing angle, sports games like FIFA or PES can be enjoyed superbly on both TVs. So both TVs are well prepared for the Playstation 5 and the Xbox Series X!
