Part 1: Dolby Vision vs. HDR10
Within 10 years there have been drastic changes in the world of televisions. From CRT we moved to LCDs and then came LEDs. Now there is a competition in video quality and the turf is occupied with HD, full HD and 4K TVs with HDR joining the race now. The old content is now known as "SDR," or standard dynamic range. While there are other entrants in the ace too like Technicolor HDR and HLG, they have so less adoption right now that we are going to keep them aside for the purpose of this article and discuss only Dolby Vision vs HDR10.
Let’s start with the basics of HDR10 and Dolby Vision:
1. HDR is an open source development and hence HDR10 is available to manufacturers for free use. Dolby Vision, on the other hand, is a proprietary software and manufacturers have to pay for it thereby increasing the cost for the customers as well. Hence television cost is more for Dolby Vision vs HDR10.
2. Currently, HDR10 and HDR10+ TVs are being made by Samsung, Sony, Panasonic, and Hisense while Dolby Vision televisions are being produced by LG and few by Philips and TCL.
3. The main technical difference between HRD10 and Dolby Vision is that HDR10 contains a static metadata while Dolby Vision provides a continuous stream of metadata to your television. What this metadata does is that it provides instructions to your television on how to render a screen. Since HDR10 provides this data only once at the start, the instructions have to be averaged out which compromises the whole video be it Daytime scenes or Night time scenes. In case of Dolby Vision, this metadata can even be per frame making each scene the best your television can deliver.
4. 12-bit colors are supported by Dolby Vision vs HDR10’s 10-bit colors. However, practically no television currently supports 12-bit color and Dolby claims that they downsample it to 10-bit to support current screens.
5. HDR10 is capable of showing content at 1,000 nits while theoretically, Dolby Vision is capable of showing content at 10,000 nits but currently comes with only 4,000 nit peak brightness target
6. HDR10 and Dolby Vision are not backward compatible. It means that your HDR content is not automatically going to play on your device that is made for playing SDR content. So if you are subscribing for some live streaming content in HDR quality and might play it on an unsupportive device, make sure to ask your provider if they support switching between the HDR and SDR types or if your hardware is capable of converting HDR to SDR.
7. To talk of a few similarities, both the formats need a television to have a resolution of 4K (3,840 x 2,160), displays capable of ~90% of the DCI-P3 color gamut and TV panels with screens capable of handling the 10-bit color format.
Those who are planning to buy televisions with high-end video quality need to decide on the type of HDR they want. While there are TVs with both HDR10 and Dolby Vision, you can also reduce your expense by selecting TVs with only either of them. Also, most TVs which support Dolby Vision will usually come with HDR10 support.
Once you have made a selection, do take care to find it if it is only “supporting” HDR content or actually utilizes the content in the best way possible. Many manufacturers label their TVs as 4k UHD but in reality, only the panel is 4K, the TV itself doesn’t support HDR. Make sure to check for 10-bit panels and not 8-bits. Sometimes manufacturers provide a panel which produces enough nits that the contrast though not near to a 10-bit panel, is much better than a regular 8-bit panel.
While the explanation above clearly tells why Dolby Vision gives better video quality, it is not that HDR10 is completely useless. With the right implementation, an untrained eye might not even be able to decipher the video type on the same television. Your Blu-Ray’s too contain only 8-bit color depth, so playing it on your new TV is not going to give you any better viewing experience but it does help you get an idea how your content is going to look on an HDR10 supported device.
If you compare TVs with Dolby Vision and HDR10, then surely it is a no-brainer that Dolby Vision comes out as the winner. However, there are a lot of improvements going on with HDR and the current HDR10+ takes care of the problem of static metadata with a continuous stream of metadata, 4000 nits of brightness and 10-bit color depth. With Dolby Vision vs HDR10 though, the winner is clearly Dolby Vision.
