Lenovo C940 HDR/Dolby Vision

2020-02-06, 22:59 PM

Hello!

I got a new C940 today, i´ve updated all drivers and installed some programs, everything is great so far, but unfortunatley I have one problem.

HDR/ Dolby Vision doesn´t seem to work right (e.g. in netflix there´s no option for HDR) . Also I figured out that i can´t change profiles in Dolby Vision (tried reinstalling the app, after I was able to change to the bright-, darkmodus for some second ..., but now all dropdown options are missing again.)

I´m a lil bit worried and really hope that this is not hardware related, but idk?

Does anyone have an idea what I could do ? Help would be greatly appreciated.

Thanks a lot in advance!

 

I´ve attached soem screenshots and hope that they´ll help to indentify the issue.

@Auxen_Lenovo First of all thanks very much for your help.
Now it´s "semi-working". Netflix Display Dolby Vision now and HDR seems to work.
But there´s still no dropdown menu in the Dolby Vision App. ( I´ve tried reinstalling, after those option were there for a moment, but then disappeard again). Also HDR still doesn´t show up in in the windows settings (use HDR games and apps is still marked as no: idk whether this is important?)
Do you have any Idea on what to do ?
Again thank you so much!

That link is broken, I have the same issue. I use VUDU for all my 4k movies, can't stream them in 4K quality.

 

Thanks.
