RTD1619DR based Zidoo Players, Dolby Vision and LG TVs

I gathered the information regarding issues with Dolby Vision and LG TVs from the Zidoo forum.

Different LG owners at Zidoo forum have posted the problem with Dolby Vision not working together with their LG TVs.

Hi, can anyone who experienced the constant black re-synch problem with this chipset and LG tv’s when outputting Dolby Vision, VS10 or LLDV at 4K 23.976 hz please post here, yet another firmware today and no fix, it has been a day one problem and begs the question exactly which ‘top rated’ Dolby Vision sets this box has been tested with?

@mirror, can you confirm Zidoo is actively working on a fix for this problem? Seems like tumbleweed every time it is mentioned.

If your box can’t work with my multi award winning TV I will have to send it back for refund. Sorry futeko, I know it isn’t your fault but at the moment it is a waste of my money.

I have the same issue, dolby vision logo appears as usual, then black re-sync dolby vision logo appears again, more re-syncs, just installed this new update today and still not working. I’m assuming it will be fixed eventually otherwise the box would have gone back already.

Ok when i use LLDV or VS10 @23.9FPS ON A 4K HDR video, I’m also getting short black screens (resync). When i deactivate the frame rate switch and play the 4K HDR videos @60fps, these short black screens are gone and everything works fine. When I use the LLDV (OR VS10) ON A 1080P Video everything works without black screens, on 60 and also on 23,9fps So these black screens only occur when I use LLDV or VS10 when i activate it on 4k Videos @23,9fps. 4k Videos @60hz and 1080p Videos @60 and @23,9hz work. So these guys that are saying it works, can you please test it with set the frame rate switch in the playback options to “Frame-Rate And Resolution” on. And test it with a 4k hdr movie? And yes I have changed my hdmi cable, I used a new hdmi 2.1 cable, and also the one that is included in the box of the z9x. Please fix this, I can’t use LLDV since day one, it only works when I play my 4k hdr movies @60fps My tv is also a LG c9

OK, We’re going to buy a LG C9, and take a look what happens.

We have communicated with dolby. At the same time, dolby and LG engineers also communicated, they confirmed that this is a bug due to LG. And dolby does not recommend us to make compatibility modification to this problem, because it will destroy the compatibility of the HDMI protocol. Anyway, Before LG fix this problems, we will see if there are any temporary ways to solve it
