Intel HD Graphics 620 - 4k TV not working

[RNord2]

Hi,

I'm trying to connect my laptop with Intel HD 620 to a 4K Samsung TV using HDMI.

My laptop is a Acer Swift 3.

Every since your last graphics update my TV only produces a black screen.

The computer sees the TV but when I try changing either HZ or resolution the whole computer freezes and I need to force it off.

What can be wrong?

Regards

Did a rollback to the old driver.

Worked.
