Zidoo has done an outstanding job and the conversion from HDR to SDR BT2020 works really well !! Projector users will certainly benefit from it, as most projectors allow the manual selection of BT2020, while playing a 4K SDR content. In my oppinion the results are better than other players such as the OPPO 203, as for example there is no black crush (there is on the OPPO 203), no posterization and the highlight cutoff curve is smooth with no instability (a problem also found on the OPPO). You can chose any of the gamma conversion curves (bright, Vivid, Movie) depending on the HDR nit content, and after some tweaking on the gamma settings of my projector, the results are very good.
