Forget 4K! HDR Is The New Buzzword
There was a time when TVs used to sell solely based on resolution. We started with 480px, then went on to HD Ready, Full HD, 4K and now we even have 8K TVs available in the market. So, does looking at resolution alone help you buy the best television with outstanding visuals? Not exactly. If resolution is all about the quantity of pixels, HDR is about the quality. And as with everything else, quality is more important than quantity!
What is HDR?
Dynamic Range essentially refers to the range of contrast and colour palette that the TV is capable of displaying. In HDR TV this dynamic range is more and hence each pixel can display a wider colour range of varying brightness, which in turns reflects a higher contrast ratio.
A 4K TV with HDR has vivid, bright and colourful visuals that are close to real life. As it has a better contrast ratio, blacks appear darker and whites appear lighter and the various gradients of colours are clearly visible. This ensures even minute details are clear and not lost. Combine this with the local dimming technology available in higher end TVs and you get outstanding clarity even in dark scenes.
In order to enjoy outstandingly vivid and colourful visuals, your TV should be HDR compatible and so should the content you see. Videos available on Netflix, Prime, YouTube, Hotstar and such VOD apps are HDR compatible. But the cable TV content is not.
HDR TV Formats
When you buy a 4K TV, don’t choose one just because it is HDR compatible. More importantly, look at the HDR formats it support. HDR 10 is the base standard, while Dolby Vision is the gold standard available predominantly in high-end TVs from LG, Sony, TCL, Hisense etc. Samsung supports HDR10+ content- a format it developed in collaboration with other companies. In their attempt to promote HDR10+, even high end 4K TVs from Samsung don’t support Dolby Vision.
Now, let us take a look at the different HDR formats in detail.
HDR 10- As mentioned, it is the base standard. A TV that is HDR 10 compatible will be able to display 1 billion colours and has a maximum brightness of 1000 nits and colour depth of 10 bits. It is an open format and hence it is not enforced by anyone. So, if a manufacturer says his TV is HDR 10 compatible, you have to take his word for it.
HDR 10 contents are static. This means, the color calibration is set for a movie or a show. But in Dolby Vision, this is set per frame.
Dolby Vision- As this format is licensed by Dolby, you can rest assured that if a TV’s specifications say Dolby Vision compatible, it will be so in actuality. As mentioned earlier, the calibration in terms of colour, contrast and brightness can be set frame by frame.
Dolby Vision content can be mastered to display 68 billion colours and peak brightness of 10,000 nits. But at present, the displays are not capable of showing such bright content.
As it can support such a wide palette of colours, what you see on TV will be exactly as what the director of the show or movie intended.
HDR 10+ content has a peak brightness of 4000 nits. It was developed by a consortium of Samsung, Panasonic and 20th Century Fox. It is definitely better than HDR10, but not quite there when compared with Dolby Vision.
HLG is HDR for cable TV. Unfortunately, in India, we don’t get HLG content from our broadcasters.
What To Buy?
If you are a videophile who enjoys crisp, clear and vivid visuals, and if your budget permits, buy a 4K TV that is Dolby Vision compatible. Or else, at least opt for a Samsung TV that is HDR10+ compatible.
But if you are someone who can’t really distinguish between HD ready, Full HD and 4K content visually, then, you needn’t give much focus on these aspects and would be better off buying a budget friendly Full HD or 4K TV of desired size.

ESCP Business School executive president and dean Leon Laulusa, said Taillard’s expertise in creativity and marketing, combined with her long association with the institution, made her well placed to shape the campus’s next phase. He credited her with launching the MSc in Marketing & Creativity, now one of the school’s flagship programmes.
ESCP London chairman of the board of trustees Lord David Gold, said Taillard would build on the campus’s recent momentum, citing her academic leadership and international outlook.
A L’Oréal professor of creativity marketing and former UK head of faculty, Taillard has been central to ESCP’s push for innovative pedagogy that bridges academic research and professional practice. She was recently shortlisted for the Times Higher Education’s Most Innovative Teacher of the Year award.
Taillard said her focus would be on expanding the programme portfolio, strengthening lifelong learning and deepening links between academia, industry and local communities, aligned with ESCP’s Bold & United strategy.
She holds an MBA from Columbia Business School and a PhD from the University of London, and has held several senior leadership roles at ESCP since joining its permanent faculty in 2007. The London campus currently serves more than 1,900 students and executive participants each year and is ranked second in the UK by the Financial Times.

Amish Tripathi awarded honorary doctorate by University of York
YORK: Bestselling author and former diplomat Amish Tripathi has added a new title to his name, Doctor of the University.
The University of York in the United Kingdom has conferred on Tripathi an honorary doctorate, honouris causa, recognising his contribution to Indian literature and his role in carrying Indian culture to audiences around the world.
In its citation, the University described Tripathi as the fastest-selling author in Indian publishing history. His 12 books have sold over eight million copies globally, earning him a regular place on Forbes India’s list of influential celebrities.
Beyond the printed page, Tripathi is a familiar voice and face to viewers. A seasoned broadcaster, he has hosted acclaimed documentaries, including the award-winning Legends of the Ramayan. He is also co-founder of Tara Gaming, the studio behind Age of Bhaarat, billed as India’s first AAA video game. Before returning to full-time creative work, he served as minister for Culture and Education at the Indian High Commission in London.
The honorary degree was presented at the University of York’s winter graduation ceremony in the second week of January 2026, in the presence of students, faculty and guests from across the world. In awarding the honour, the University praised Tripathi for deepening global understanding of Indian values, traditions and storytelling.
He was joined in this year’s roll of honour by three other distinguished figures: renowned mathematician professor Simon Donaldson, ecologist professor Sue Hartley OBE, and dame Amanda Blanc DBE, group chief executive officer of Aviva.
The University of York awards its honorary doctorates to individuals whose achievements show exceptional distinction and reflect the institution’s values. For Tripathi, it marks another chapter in a career that continues to blend myth, modernity and meaningful dialogue across cultures.

Niit MTS snaps up Sweetrush in $26m USA push
NEW DELHI / SAN FRANCISCO: Niit learning systems limited’s managed training arm, niit mts, has bought 100 per cent of Sweetrush Inc in a deal worth up to $26 million, tightening its grip on the USA and sharpening its ai-led learning offer.
The acquisition, completed through Niit (USA) inc, includes performance-linked earn-outs over five years.

The aim: turn project work into sticky, annuity-like contracts and lift wallet share across enterprises, professional associations and not-for-profits.
Niit MTS chief executive officer and executive director Sapnesh Lalla, said the tie-up brings “human-centred learning craft and global operational scale, powered by technology and AI, under one roof”.
Sweetrush chief executive officer Danielle Hart, said joining niit offers a bigger global runway while preserving the firm’s culture of care and innovation.
Niit MTS vice chairman and managing director Vijay K Thadani, called the deal a boost to its outcome-focused portfolio, marrying strategic learning interventions with delivery at scale.
Sweetrush’s founders struck a similar note. Arturo Schwartzberg said the teams and culture would remain intact, now backed by Niit’s heft, while Andrei Hedstrom said the combined ecosystem would “amplify” the firms’ impact on mission-critical learning.
