OLED is 3840x2160 no matter what. Nothing else besides 3840x2160 would be true 1:1 without going through a scaler either in the display or the GPU. OLED is a fixed pixel array display. There would be no such thing as 2560x1440 showing 1:1 on OLED.Then you are actually sending a 4k signal which defeats the purpose of 120hz over hdmi right meow. Question is can the tv display native 1:1 without scaling it if it gets a 1440p signal. Makes for a 36.5" display.
