This is the email that I wrote the technical team of VU Technologies Pvt. Ltd. India explaining about the 8-bit HDR (which doesn't and shouldn't exist) that their TV has offered me. Hence, I was too lazy to edit the email and post it here so here's the original thing:"Dear Team VU,I am in utter disappointment after realizing that your so-called VU Premium Android TVs are not HDR by any means!I presently own a twice-replaced 55-OA and it is fortunately working well so far but of course I have many other issues apart from this seemingly-deceptive strategy undertaken by your marketing/branding deptt. The proofs of the TV not being HDR are attached below and explained in the following:1 - Under 'Stats for Nerds' in official (stock) YouTube and Smart YouTube apps, it shows "bt709/bt709" (aka Rec.709) colorspace/color gamut which undoubtedly and apparently is an HDTV standard color spectrum coverage and not a 4k HDR by any means. This wiki article explains everything an end-user must know before buying a true-HDR TV: https://en.m.wikipedia.org/wiki/Rec._2020?wprov=sfla1 2 - The peak brightness is just 450 nits which again isn't mentioned whether it's partial peak brightness or overall peak brightness or average peak brightness. Very dumb for a company to not mention the detailed brightness info.3 - I can't find any Dolby Vision engine/DV system app in All Apps that confirms whether this TV supports Dolby Vision.4 - I tried to play 4k60p HDR & SDR and 4k30p HDR & SDR content off of different sources like external hard drive, and Plex but literally all of the HDR content displayed with washed-off (decolorized) colours and some of the HDR videos even forced a hard-reboot of the TV! Crazy ryt? If the TV was true-HDR10 and DV, the content would be displayed in proper HDR colours.5 - The color depth of this Hisense panel in Aida64 app shows as 8-bit and you know the minimum bit depth required for HDR is 10-bit and 12-bit is maximum. Another solid proof of this TV not being HDR.Now coming to 60p (aka 60 fps) playback. No video plays smoothly without frame drops and it's just a total disaster for eyes to look at when 4k60p content is played for prolonged time. Significant jittering/stuttering is observed, especially near the edges of the screen while the 60 fps content plays. This effect was even caught up easily by my parents themselves at once.I would request you to please forward this message to your higher authorities so that they also know this truth and the fake advertising that you're doing on every box as HDR10 and Dolby Vision, not to mention the Dolby Vision trademark as well.Regards,Navdeep Singh Thind"I hope some of you guys got helped by this. Please never take HDR for granted these days in lower-tier brands!Visit the following link for proof of this TV not being able to display true 10 bit HDR colour gamut: https://photos.app.goo.gl/GtFNx658JQcZSPKN6 .
