How to solve the problem with running Modern UI applications on a connected third-party display?

Question

Windows

Good afternoon!
I ask you, kind people, to help me solve an already fairly sore problem.
Given: Asus Eee PC X101CH netbook, old Flatron F700P monitor, VGA cable.
Recently I installed Windows 8.1 on my “netbook” with a native resolution of 1024x600 pixels: I know that there is an incompatibility problem (Windows 8.1 officially supports 1024x768+), however, by a simple registry edit, I set this minimum supported resolution, which I could easily “fool” Microsoft's screen check program during OS installation. Actually, after successfully installing the OS on my device, I decided to try running the notorious Modern UI applications: the computer, after hanging for 30 seconds, persistently went into Reboot (launched the Windows Store). “It’s still about the screen resolution: probably, the system will somehow determine the native for this display and prevent these applications from starting and working correctly!” - I thought and took out an old dusty monitor Flatron F700P (1280x1024) from the balcony. Through simple manipulations, I connected the box to the "netbook" through an ordinary VGA cable and set up the display of the picture exclusively on Flatron'e. However, the situation repeated itself! The computer also goes into reboot.
The next day I decided to try it all on an LCD display via HDMI: needless to say, the result was deplorable.
So, now, having changed all possible video drivers to the hated by many Intel GMA 3600, I turn to you, dear readers. Maybe something is wrong with the video accelerator? Or are applications launched initially even on the “netbook” display turned off, and only then transferred to a third-party monitor? I ask you to help and excuse for the clumsily written text.
PS Interestingly, applications such as "Photos", "OneDrive (ala SkyDrive)", "Camera" work like clockwork.
