How to force DisplayLink to use a video card, otherwise it's terribly buggy?

Question

GPGPU

My screen is connected to the PC in two ways: VGA and DisplayLink (USB).
VGA often loses contact due to a loose connector and the image is slightly blurred (this is not connected with the connector).
There are no problems with displaying via DisplayLink: the image is accurate, everything is fine with the USB cable. But, after launching DisplayLink, on the desktop and in Chrome, the mouse lags slightly, when you open Start, the dimming of the background is not smooth, and launching programs like Skype, VisualStudio or Minecraft generally freezes.
I believe such glitches are due to not using the video card and, accordingly, excessive load on the CPU.
So how to wean DisplayLink to eat resources?

Answer 1

Does DisplayLink have any connection with the video card. In my opinion, this technology was created in order to reduce the number of connectors on all sorts of phones, cameras, tablets, and the main task was just to show the picture on the big screen, and not to keep the game FPSs. I understand that the monitor you have is quite new and with a high resolution, that for vga there is already too much, so it falls off sometimes, but what prevents you from connecting the monitor via digital (HDMI, DVI)?
