Dolby Vision has long been pitched as the "best" HDR (high dynamic range) solution out there. The Dolby system uses dynamic metadata to tell the TV the brightness for each frame or scene to increase the impact of HDR over static systems - like HDR10 - which only uses that data once to set the brightness for the entire film.

This holy grail TV tech has long been associated with high-end TVs. It has been something offered on LG's OLED TVs for a couple of years and for the most part it has been those expensive OLED sets that offered Dolby Vision

That's all set to change, with Philips saying that 90 per cent of its 2019 TV range will support Dolby Vision. That's not just the new OLED 804 and 854 models, but across LED models too - through the 6000, 7000 and 8000 series. 

This makes Dolby Vision an accessible HDR technology where in previous years it hasn't been. While Philips is yet to announce the pricing for its 2019 line-up, we're expecting some of these models to be available for under £800, like the 7304 - which Philips is candidly calling The One

There's an important point that's often missed about dynamic metadata systems too: they are a lot more effective on mid-range TVs than on high-end models and can really boost the viewing experience. While top tier TVs are often loaded with better panels, extra processing and in many cases more precise dimming, systems like Dolby Vision can make better use of the skills of mid-range TVs - so you get a better picture. 

The same is true of the rival system HDR10+. That system - backed by companies like Samsung - has a similar setup and as it happens, Philips is also supporting HDR10+ on these models two. 

The availability of Dolby Vision content has been expanding over the past few years; it's becoming more common from Netflix, it's appearing on next-gen Ultra HD Blu-ray discs and there's a healthy selection of DV content available from iTunes on the Apple TV.

Sadly, Dolby Vision isn't something that can be retro-updated, so there won't be DV support on 2018 models - not even the flagship Philips OLED+ 903.

Philips new range of TVs are expected to be available in the first half of 2019, prices to be confirmed.
