I have an Nvidia GTX 1660 (not super powerful, but I would think it is enough), but no matter which HW Accellerated decoder I choose, I either get a green screen, or tone mapping just doesn't work (still washed out).  Which decoder should I choose?  (Cuvid, DX11, or generic Nvidia)?  I also have a Intel UHD 630 if that is better for HDR decoding.
