LG C9 vs LG CX TV comparison 2021/04

It is no secret that the LG C9 is one of the best TVs of 2019. The OLED panel 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.
The LG C9 is available in 55, 65 and 77 inch.
