hi.
i have an hp envy 20 all in one and i bought an usb to vga adapter from displaylink to add an external monitor and instaled the latest drivers, and my problem is that the external monitor looks flickering and the colors are in 4-bit, so the image is very poor, i have tried all resolutions with no improvement.
also i note that the windows display manager recognize the screen, but the intel hd graphics control center does not, on it only shows the main screen and cant add another one, i´ve tried to update the driver directly from intel and cant do it, it tells me to install the newer one from the manufacturer so i have those even if intel tells me that are outdated.
i hope some one could help. thanks
