Differentiating the impact of Dolby Vision 2 on to budget televisions is substantial, more so than anticipated, as disclosed by a Dolby specialist, detailing how the technology operates.
Hisense, a leading manufacturer of TV models, has announced that it will be the first to integrate Dolby Vision 2 into its premium TVs, particularly those equipped with RGB-MiniLED technology.
During a recent demonstration, Dolby Vision 2 showed significant improvements over its predecessor. Colours in Dolby Vision 2 appeared more saturated, and shadows and dark areas looked deeper. The improved perceived contrast resulted in reflections of light looking clearer and more lifelike.
The demo also revealed that there was a perceived improvement in fullscreen brightness in Dolby Vision 2, particularly in landscape images. White tones in Dolby Vision 2 were cleaner and elevated more compared to Dolby Vision 1, making the image look more detailed.
Dolby Vision 2 will come in two flavours: Dolby Vision 2 and Dolby Vision 2 Max. One of the key features of Dolby Vision 2 is Precision Black, which enables creators to add information about their bias light and set where their first perceived step out of pure black and into near-black levels will be. This feature may help with the hue of black tones, making them look more true to life.
If you have a Dolby Vision 1 video on a Dolby Vision 2 TV, you should see some improvement due to the better smart picture analysis. The improvements come from providing more data to the TV about how the image is supposed to look, as defined by the creators when they encode to Dolby Vision.
However, it is unlikely that current TVs will be updated for Dolby Vision 2. If Dolby can get the big streaming services and creators on board for Dolby Vision 2, it looks like a genuine upgrade for inexpensive TVs coming out in the future.
The Precision Black control is only recognized by Dolby Vision 2 TVs and would be ignored by Dolby Vision 1 TVs. This means that creators who use Precision Black in their content will ensure that their work is displayed as intended on Dolby Vision 2 TVs.
The improvements in Dolby Vision 2 do not come from changes in the colour or dynamic range spec for creators. Instead, Dolby has improved the engine that adapts the picture data to each TV for Dolby Vision 2.
Dolby Vision 2 was demonstrated on Hisense A5 TVs, which are entry-level LCD TVs with full array backlighting and QLED. This suggests that the improvements in Dolby Vision 2 are accessible to a wide range of TVs and not just high-end models.
In conclusion, Hisense's integration of Dolby Vision 2 into its premium TVs marks a significant step forward in HDR technology. With its improved engine and Precision Black control, Dolby Vision 2 promises to deliver a more detailed and true-to-life viewing experience.
