Our Verdict
LG 48GQ900-B
LG 42 C2 OLED
The LG 42 C2 OLED and the LG 48GQ900-B offer nearly identical picture quality, but they have different inputs and different extra features. The 42 C2 OLED is a TV we've tested as a monitor, so it has features you'd typically find on a TV, including extra image processing options, a fully-featured smart interface, and a tuner. The 48GQ900-B, on the other hand, is designed to be used as a monitor, so it lacks a smart interface and advanced picture processing options. However, it has inputs more typically found on a monitor, including a DisplayPort input and a USB hub.
