Our Verdict
LG 45GX950A-B
LG C5 42 OLED
The LG C5 42 OLED and the LG 45GX950A-B are both large OLED displays with a few differences. The C5 is a small TV that's popular to use as a monitor, so it has many features that are typical of TVs, including a built-in smart system, eARC/ARC audio passthrough, and a processor. The 45GX950A-B has more typical monitor features, like a Dual-Mode that switches its native 5k2k resolution and 165Hz refresh rate to a 1080p resolution and 330Hz refresh rate. Although they both have WOLED panels, there are a few differences, as the C5 gets brighter in HDR, while the 45GX950A-B has a dedicated sRGB mode that results in better accuracy before calibration. Overall, the C5 is the better choice if you want a small TV that you can use as a monitor, while the 45GX950A-B is the better choice if you want an ultrawide that you're going to use more like a typical monitor.
