The demonstration itself started with HDR footage of a firework display at night and it's a credit to Panasonic that they were prepared to use such challenging material to show the full capabilities of the DX902. Although there was a tiny bit of haloing it was barely noticeable, and there was almost no difference between the DX902 and the OLED monitors, aside from the blacks being a shade darker on the OLEDs.
Just comparing the SDR to the HDR version showed the true potential of increasing the dynamic range of an image. The DX902 held up extremely well against the £30,000 professional OLED monitor, with the two looking very similar and again only the OLED's slight edge with blacks showing through. The same was true with the colour accuracy and again, there was very little difference between the professional monitor and the DX902, which is incredible when you consider the price differential.
