Detailed facts: LG C9 or Sony A9G

The LG C9 is a fantastic OLED TV that offers the usual advantages of an OLED panel: Perfect blacks, an infinite contrast ratio and a very wide viewing angle. These advantages are enhanced by HDMI 2.1, which combined with a very low input lag provides great gaming performance. But the C9 is also a great choice for movies, TV shows and HDR content.
Sony A9G is also a great OLED TV, but it has a different focus. The panel comes from LG Display itself, so the picture characteristics are more or less the same. However, the processor of the Sony AG9 is better than the C9 in terms of interpolation and image processing. In addition, the A9G offers sound from screen, which provides a fantastic sound experience. It's less suitable for gaming, though.
