Can Dell S2350m monitor be used with Inspiron 15 7000 series laptop
I purchased the Inspiron 15 7000 series laptop 1-1/2 weeks ago at Best Buy. The salesperson had me buy a VGA to USB adapter and suggested I plug it directly into the USB port and not through the USB hub I also bought. However, I cannot get the monitor to work. The computer is running Windows 10. The display shows 3 monitors (I also have a monitor on the HDMI port) but the settings for the Dell are greyed out. On other computers, shutting the laptop cover allowed the use of two external monitors, but I haven't been able to get this to work. Even unplugging the HDMI monitor doesn't allow the Dell monitor to display. Does this monitor work on the newer laptops? If so, what else can I try? And am I limited to two monitors on Win10 with this computer?
