Before you buy your new 4K TV...

This may be out by the end of the year and may become integrated into the TV

While there may be some advantage to an expanded colour gamut, I have no idea why a TV that's "40 times brighter than conventional" models is in any way desirable.

My current television can output more light than I find comfortable; and I don't need my TV to double as a sunbed.

High native contrast is one of the foundations of a good picture. Excessive brightness isn't.

The sad thing is that manufacturers and technology companies invest in ideas that are marketable through quoted bigger numbers.

For customers with little knowledge of how televisions work, these numbers may suggest they're investing in something demonstrably better, when in reality there's nothing worthwhile gained.

In the same way as you would go for better amplification when choosing your AV receiver despite never listening at loudest volume? :shifty:

Right, but an equivalent argument with regard to video performance would refer to native contrast rather than brightness.

As we both know, many televisions out there already can produce a far brighter picture in Dynamic mode than recommended by organisations such as THX and ISF. However, a fair proportion of these televisions have poor native contrast.

Improvements at the lower end of the contrast spectrum are far more desirable; and the current trend away from self-emissive panel technology means we're moving backwards in terms of native contrast performance.

If Dolby's claims related to native contrast I'd be genuinely intrigued. However, Dolby only makes claims about panel brightness gains, at a factor of 40, no less.

Such "gains" are entirely superfluous in terms of domestic viewing requirements, and offer no advantage when watching at lower brightness levels.

Then again, some people insist on watching their TV in Dynamic mode, so may welcome Dolby's retina-searing technology.

Another marketing gimmick that once the tv is home will be turned off like every other special feature

vivid colour -off

colour remaster - off

reversal film effect - off

ambient sensor - off

noise reduction - off

mpeg remaster - off

resolution remaster - off

caption smoother - off

brilliance enhancer - off

24p smooth film - off

anyone seeing a pattern here?
