Añado. También muchos de los problemas que han reportado los compis de avsforum, podrían ser debidos a los cables HDMI, ya que HDR va a requerir de un ancho de banda de hasta 18Gbps.

Dynamic Range (HDR) is an advancement in picture quality that will quickly find a market. It will change the AV industry more than any other display technology that has debuted in the last few years. The upgrade to HDR is easy to see by the customer and will establish a foothold in the market quickly due to its stunning dynamic range of brightness — like really, really stunning. HDR creates pictures in the same way that the human eye does and makes videos come to life with shadows and shading details the likes of which we have never seen on other displays. Viewers can instantly notice the difference and begin imagining it in their homes and businesses. Yet, we are facing one problem to implementing HDR — this upgrade has a lot of technology behind it that will not be understood by everyone.

The most prominent issue is that HDR requires the maximum bandwidth specified in the HDMI 2.0 spec — up to 18Gbps for support of the full–color spectrum and detail it provides. The components, the cables and accessories must all meet the full specification. The problem is that HDMI products can legally state, “supports HDMI 2.0” when they only fall into the minimum specification range of HDMI 2.0 under 10.2Gbps making them unable to support the bandwidth requirement for HDR. Making it even more complicated is that the hardware specification for HDR is HDMI 2.0a. Luckily, making the move from HDMI 2.0 to 2.0a is going to be done with a firmware upgrade on most devices. Therefore, the products that only meet the HDMI 2.0 minimum–specification will not support HDR.
