Screen Blink Bug at RTX2080

the same on my case, black screen flashing, when you move the mouse etc…with tv samsung 65 Q8 on 4k resolution. RTX 2080… any solution? . I am working on a videogame and now, I can not use my UE.
I finish to build my new pc today and when i run UE, woooooooooo

Please, any suggestions other than to return to drivers 388, or the odious hdr of windows10. I have to test many game projects and I am ok with my current hdr per application. Every hour without solution counts for me.
