Our Verdict
LG 48 C1 OLED
LG 48GQ900-B
The LG 48 C1 OLED and the LG 48GQ900-B perform nearly identically, but they have different inputs and different extra features. The 48 C1 OLED is a TV that we've tested as a monitor, meaning it has features you'd typically find on a TV, including advanced image and motion 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.
