Prelude:

I have GT-1030 with AMD R3 1200 on 8gig mem. Till now had only one display connected (Samsung la22d404e4r, 1080pTV) via HDMI to VGA, worked like a charm. Now, I've connected secondary display (cuz I use AE a lot) which is old LG L1730S Flatron (connect via DVI-I to VGA). (Both monitor show as Generic PnP monitor in Device Manager)



Problem:

1. Screen flash black, make hardware connected-disconnected sounds, while I try to open new tabs or switch in full-screen windows. Sometimes simply opening Start menu makes this issue.

2. All windows from my secondary, resize and shift to my Primary display.



Solutions Tried but haven't solved so far:

GPU Driver update

Tweaking via control panel

Tweaking via Nvidia panel

checking cables

checking converters to VGA (on other systems too)

checking for loose connections within the case

Updating Monitor drivers (still both show as Generic PnP monitors)

Look in Reliability History and Event Viewer for error codes and warnings that correspond with the times that black screens occurred.

Windows 10?

Run the built-in Windows 10 troubleshooters. The troubleshooters may find and fix something.

Likewise for "sfc /scannow" via the Command Prompt.
