Our Verdict
LG GX OLED
LG C1 OLED
The LG GX OLED and the LG C1 OLED offer very similar performance overall. The biggest difference between them is design. The GX is more of a statement piece, extremely thin, and designed to sit flush against the wall. It doesn't even come with a stand out of the box—you have to buy one separately. In terms of performance, both TVs have OLED panels with stunning picture quality, but the C1 comes with the latest version of webOS and a redesigned Magic Remote, along with a new gaming setting to reduce input lag further. Both are amazing TVs.
