I have just purchased this TV and trying to load my own art but I do not want a border / mount (I want the image to fill the screen edge to edge). I can find no way of switch off the mount. I can select Modern or Shadow, but there is no option for None.
Having read various threads on here and blogs, I have tried various image sizes (1920x1080 72dpi), (3840x2160 72dpi) and (7200x4050 300 dpi). None of them offer me a No mount option.
This must be possible!! Other threads with other models / years appear to have achieved it, but it's not happening for me.
