The main difference between the two models lies in their model numbers: OLED77G58LW and OLED77G57LW, both are 77-inch G5 series OLED 4K TVs from LG for 2025. However, available information does not specify any technical or feature differences between these two specific models. Both share the same core specifications such as OLED screen technology, 4K resolution, Dolby Vision, HDR10, HLG support, and a 120 Hz native refresh rate. They also have four HDMI inputs and weigh approximately 33.6 kg.
The OLED77G57LW is confirmed as part of the G5 series with the Alpha 11 Gen 2 processor, new tandem OLED technology, and no included stand (wall mount only). The OLED77G58LW appears to be a very closely related or possibly a regional variant of the same model, with no distinct feature differences documented in the sources.
Therefore, the difference between the OLED77G58LW and OLED77G57LW is likely minimal or related to regional model numbering rather than hardware or performance changes.
