The LG C5 42 OLED is a 42-inch, 4k OLED TV that’s popular to use as a PC monitor. It’s an updated version of the LG C4 42 OLED, and it’s the smallest size of the C5 series models. It’s similar to the slightly bigger 48-inch TV, as they don’t have the Brightness Booster technology that the 55-inch and larger sizes have, so the smaller models aren’t as bright. Besides that, it has many of the same features as the larger sizes, including 4k @ 144Hz support in its Game Mode, HDMI 2.1 bandwidth, and VRR support. It’s different from most typical PC monitors because it has a built-in processor, supports eARC/ARC with Dolby Digital passthrough, and has built-in webOS, but it doesn’t have a DisplayPort input or an ergonomic stand.
