This is built to match the width of the 55" GX OLED. Do you make a model to match the 77"? I can only find the 55" model in stores. If you do make a 77" model, can you provide a link to where it is available to buy?
Asked by: BryceVegas
I actually believe the physical width of the soundbar matches the physical width of the 65" GX OLED (56.9" wide). I also don't believe LG has any intentions of manufacturing different physical widths to match the other panel dimensions (55" or 77").
