Vega 56 to Shimian Monitor Driver issue

[shoenberg3]

Since my monitor (Shimian 27" inch IPS monitor) does not have a DP port, I had to purchase a rather expensive adapter to connect it with the Vega 56.

(https://www.amazon.com/gp/product/B00A493CNY/ref=ask_ql_qh_dp_hza)

It actually works okay when I don't have any Radoen drivers installed. However, when I install latest Radeon drivers (also tried blockchain drivers), static artifact takes over the entire screen (I can still somewhat see the what's underneath). Like this:https://ibb.co/eGYMLz

Only resolution is to uninstall the drivers, but then I can't play any games and have also stability issues.

I tried to setting the refresh rate on Radeon settings, with no avail. My guess is that the adapter isn't able to "handle" the latest features on Radeon drivers?

Help please.

I would say get another monitor, supporting DP. They aren't that expensive. Or at least use a test monitor with DP to make sure the card isn't bad.

THhe card does work fine on a test setup.

Any one with ideas? I am getting rather desperate here.

Going through the Q&A on the link for your adapter, it looks like others have had the same issue with the Shimian monitors. The only suggestion was to downgrade drivers. But that doesn't really seem like much of a solution to me.
