Newer laptops with HDR-ready display may cost even more. At present, a laptop with the most basic GeForce 10 series processor costs over Rs70,000. They should also be running on Intel’s 7th Generation Core i3, i5, or i7 or higher processors and must have Nvidia’s GeForce1050, 1060, 1070, and 1080 graphics.
Netflix has specified that the HDR 10 content will only work on PCs running the latest Windows 10 Creators Update (version 1703). To play HDR content on Windows 10, users will need PCs that support the HDR technology and meet minimum system requirements. However, as of now most TVs allow only 10 bit colours. The bit size determines the number of colours in each pixel, resulting in slightly better colours. PlayReady 3.0 has a few requirements, though, if 4K video is going to play correctly, and you need to have the right Netflix plan. The other major difference between the two is that HDR 10 supports 10-bit colours, while Dolby Vision supports 12-bits. Two services that will play 4K video on a PC include Netflix and Vudu, and that’s thanks to a Microsoft copy protection scheme called PlayReady 3.0 DRM (digital rights management). The latter is Dolby’s proprietary format supported fully by them and comes with a licensing fee, which is why the adoption is limited to high-end TVs. It requires no licensing fee and can be tweaked by the manufacturer of the TV or PC for better results. The former is an open format, promoted by a consortium called UHD Alliance. There are two versions of HDR-HDR 10 and Dolby Vision. The other advantage of HDR over SDR standard is that it can reproduce the red, green, and blue colour gamut more vividly and clearly. As a result, bright areas look brighter and dark areas look darker on the same screen, if the display in the smartphone or PC supports it.
As the name suggests, HDR enhances this dynamic range, resulting in richer colours and better contrast (it determines how bright and dark the video on a screen will look). Dynamic range is basically the ratio between the darkest and brightest part in a video played on any screen. The big difference between HDR and SDR (Standard Dynamic Range) content is the way it reproduces colours.
