Flickering in the second monitor - AMD Radeon R9 280x

Discussion created by mr.shelly on Apr 29, 2019

I have the following problem ...

I had this graphics card so far with Windows 8.1 x64 with the Radeon software version 17.7.1 operated without
Problems or special settings.

Now I have reinstalled the system and would like to use it with Windows 10 x64 (1809).

Here I tried the different versions 18.11.1, 18.12.2, 18.12.3 but also newer 19.4.1 - 19.4.3, they all have the same problem.

Have it always cleaned between installations with "AMD Cleanup Utility".

Now to the problem description:

Both monitors display a bug-free image. But as soon as something changes. e.g. moved a window
or writing a text, the second monitor starts to flicker on an area.

If you do not actively do anything with the mouse or the keyboard, there is no flickering.

This monitor is currently connected via DVI cable, but also a change DisplayPort or another Cable does not help here.

After I also still the old system (Windows 8.1 x64) I have here also the monitor settings in the Radeon Software tested. Here the setting is 100% the same as in Windows 10 x64.

Hope for tips on my problem.
My english is not so good - sorry.
