Our Verdict

LG C4 42 OLED

LG C5 42 OLED

The LG C5 42 OLED is an updated model of the LG C4 42 OLED with minimal differences. That said, the main difference between the two is that you can enable the Peak Brightness setting in PC mode on the C5, which allows it to get brighter than the C4 when you're using it with your PC. There are some other changes, like the new remote and the lack of DTS audio passthrough on the C5, but other than that, they're very similar.
