I understand they will be using the same panel, so there are no differences between these 2 except for stand, looks, ports and extra features like PiP, KVM switch etc. right?
And backlight and software among other things… But honestly that’s like saying there is nothing different between a lemon and an orange, except for color, taste, and sourness… The price will be different, the scaler has different software features (and ports like you mentioned.) The panel being the same is just the tip of the iceberg tbh.
Spectrum Model 2, being 1440p@240Hz, is technically not feasible to have the same panel as a 4K@144Hz monitor. The actual physical pixel layout is different.
However, assume they are using the same panel. The tuning will be diverse, which affects overdrive profiles; moreover, they will feature different OSD, where the end-user can tweak a different set of settings to their liking.
