Dolby Vision IQ is an extension of Dolby ’s HDR technology that improves the picture performance of your TV whether you take in in a bright or dark room .
It was first plunge at CES 2020 to establish upon the foundations of theDolby Vision HDR . IQ is one of several intelligent , adaptive HDR TV technology that attempt to improve consider quality in everyday living way conditions .
Here ’s an explainer on how it works , which telecasting brands endorse it and whether it ’s a no - brainer to purchase a idiot box with this lineament .

What is Dolby Vision IQ?
For those in the audience who need a refresh on what Dolby Vision is , it is aHDR technologycreated by Dolby that ’s referred to as a dynamical HDR variant . It ’s used all the room from filmmakers who utilise it to surmount picture and TV , down to the television set you have in your home .
It adds metadata – fundamentally operating instructions on how the content should wait on a presentation – to the HDR signal to optimise the image on covert , whether that ’s adjusting the brightness ( brightness ) , contrast and colour .
While ‘ received ’ Dolby Vision can compensate for the capability of a video ’s exhibit , what it can not do is even off for the living way lighting conditions you ’re watching in . Due to glare from sunshine , lights on in a way or just if you ’re a person who like to watch with the lights down , these different environments will influence what is seeable on screen .
This can manifest in the viewer not being able to see all the detail in the darkest part , meaning you losing out on details within the four borders of your TV . This is where Dolby Vision IQ enters the figure .
The conundrum that Vision IQ seeks to work is that of shot light shape in a living room environment . As HDR content is dominate in darkly lit grading suites , that ’s a far yell from the elbow room witness watch film in , which are promising and full of various light root .
Dolby Vision IQ utilize the same metadata within the signal , and works in tandem with a TV ’s ambient light sensing element to detect how vivid or how non-white a elbow room is . It then adjusts the impression so HDR content retains its light ( i.e. brightness ) , and detail can be seen across the image in regardless of the amount of brightness in a elbow room . And it can do this on the rainfly thanks to the TV ’s ambient sluttish sensing element , without requiring any stimulation from the witness .
The idea is that the idiot box will take caution of the pic timbre for you , so you wo n’t call for to turn over into the options to figure out what to fine-tune . commute between promising to dark-skinned mental object , or vice versa , and the telecasting will recognise the shift and react accordingly .
The result is that details in dark-skinned scenes are more intelligible , whether in the foreground or background , and it ’s achieved without boosting the smartness to a point where the range of a function looks washed out . The final result can be subtle , but it ’s obtrusive , however .
What is Dolby Vision IQ with Precision Detail?
Dolby Vision IQ with Precision Detail ( we ’ll just call it Precision Detail ) , is a further advancement on Dolby Vision IQ . It operates in the same personal manner but adjusts the light levels in each field of the concealment to draw out more detail , increasing keenness and contrast levels for an even more three - dimensional and detailed trope .
Currently only select LG TVs support Precision Detail as it ask excess processing ability , of which LG’sα9 Gen 5 AI Processor can provide . It is expected to arrive on other TV brands in 2023 when young , more hefty TV processors launch .
Are there any other adaptive picture modes?
You may not bring in it , but intelligent picture modes are everywhere , and in some typeface , you may not make you have it on .
For instance , Panasonic ’s Intelligent Sensing is available across several oftheir OLEDand LCD video models , and works across HDR10,HDR10 + , HLG , SDR andFilmmaker modesto balance picture ’s performance . Samsung has its Adaptive Picture mode ( which in our experience wee-wee the image appear too bright ) , while Sony has its Bravia Core Calibrated fashion and there is also aNetflix Adaptive Calibrated Modesupported by select Panasonic and Sony telecasting .
And if that was n’t enough , HDR10 + Adaptive was enclose in 2021 , and achieves the same effect as Dolby Vision IQ but with HDR10 + and ( on Samsung TVs ) Filmmaker modality title . You ’ll find this HDR edition on several Panasonic and Samsung TVs .
Which TV brands support Dolby Vision IQ?
Both LG and Panasonic acquire the HDR engineering science back in 2020 across selected telecasting , and since then Hisense and TCL also joined in with their most recent sets .
There are a act of TV manufacturers that have n’t jump onboard such as Sony and Philips ( the latter has come up with its own solution in its Dark Detail Optimisation feature ) , while it ’s very improbable Samsung will adopt it as they do n’t back Dolby Vision at all .
For television that do support it , it tend to be mechanically select when the TV senses Dolby Vision content , effectively replacing the ‘ standard ’ Vision HDR scope . you’re able to , however , still swap between it and other version of Dolby Vision in the picture configurations bill of fare of a TV .
Is Dolby Vision IQ worth it?
It ’s say lulu is in the eye of percipient and whether Dolby Vision IQ is worth it depends on whether you feel it ’ll have a beneficial effect on your viewing experience , and what character of room you on a regular basis watch in .
The demos we ’ve seen have expressed insidious , rather than obvious changes , mainly relating to the retrieval of item in the darkest share of an image . It ’s not a literal night and sidereal day difference , and some may find that the epitome they see stays comparatively the same .
Having liken a Dolby Vision IQ video side - to - side with one that simply just had Dolby Vision , we did find the I.Q. compatible TV had higher detail levels , especially when confronted with dark scene or moment coiffure in a dark - meter go under
For us , we appreciate any technology that enhances the viewing the experience and Dolby Vision IQ achieves this . It may not always be the most obvious effect , but part of the way Dolby Vision IQ works is that it ’s an unseeable script that does n’t draw attention to itself . And for those who detest get to jump into the mise en scene to tinker , you may find IQ , or indeed any other adaptive picture mode , a welcome result .
