The LG C9 is also an excellent TV for other systems that use HDMI due to the lack of noticeable input lag. The other consoles include the Nintendo Switch, Nintendo Wii U, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One.
While the HDR is not the best, the C9 should be more than adequate enough for HDR-enabled games on the PlayStation 4, PlayStation 4 Pro, Xbox One S and Xbox One X.
