The LG OLED77GXPUA is part of LG’s GX series, one of the first to be introduced on the official LG website in 2020. This model features a 77-inch display, with the possibility of additional sizes being offered later. In European markets, the model is known as OLED77GXPLA.
Design and Features of the LG OLED77GX
A standout feature of the LG OLED77GX is its ability to transform into a piece of art.
