I'm a bit confused about this model as there are apparently 2 models of the same name on your site but with different specifications? For example this one is OLED, with NVidia G sync while its clone is IPS with Nvidia G sync Ultimate? On the manufacturer's website its description is OLED, with Nvidia G sync Ultimate. Are these two other models? Which one is closer to the one on the manufacturer's site? or are they just small mistakes?
