Our Verdict

LG GX OLED

Sony A90J OLED

The LG GX OLED and the Sony A90J OLED are both high-end, well-designed OLED TVs. If you want something that looks sleek and will sit absolutely flush against the wall, the LG is one of the thinnest TVs we've tested, designed to look like a piece of art on your wall. Otherwise, the two perform very similarly, delivering the same perfect black levels that all OLEDs do. That said, the Sony also gets a bit brighter in HDR and is technically capable of hitting an exceptionally high peak brightness in 'Vivid' mode, but not for sustained periods of time.
