Am hoping anyone of you might have a solution to the issue I have. I have a QE55Q90TATXXC, says on the tin that it is able to display hdr with 60hz and I am fairly certain it does when I view content natively on it. However once I hook it up to my PC with a hmdi 2.1 cable that should be able to support the required bandwidth and have a graphics card capable of said output (a nvidia 3080). But once I do, I only have 30hz available with HDR.
Following the guide to enable this provided by samsung, it says to enable extended signal, that I have but it still only displays 30hz in windows screen settings and nvidias control panel. 😞
As far as I know there are not screen drivers that I need, should be plug and play. So do anyone of you have any clues that I can try?
