Xorg.0.log with flood message "(DFP-1): connected" and screen locking every second

I’m using openSUSE Leap 42.2 (KDE) with GTX 970 (ZOTAC). I installed the recommended drive, version 375.66.

But on the login screen, the screen starts to lock up every second. This happens only when I connect my monitor with HDMI (Any resolution, but I’m using 1920x1080).
And seeing the Xorg.0.log, there are many message (DFP-1): connected.

Example:

I have tested other Linux distributions such as Ubuntu (Unity), Fedora (Gnome) and the problem continues.
I tested it with VGA cable (Monitor) on the DVI connection (with adapter) and it does not present a problem or several messages in Xorg.0.log.
I tried several settings in http://us.download.nvidia.com/XFree86/Linux-x86_64/375.39/README/index.html but without success.

Any solution?

I’d suggest to try it with another monitor and HDMI cable.

Solved! I changed the HDMI cable and the problem did not happen.
