Reboot and start tapping F2 when you see the Dell splash screen. That should open BIOS setup. Use the tab and arrow keys to navigate around, if mouse doesn't work in BIOS setup. Look for an option for Multi-Monitor (aka: Multi-Display) support. If it's available, enable that option. If that option is available, look for a second option to set Primary Display and set it to NVidia. Don't change anything else in setup, but save the change(s) and exit setup.  PC will reboot automatically when you exit setup NOTE: Unfortunately, the online Service Manual doesn't list the BIOS setup options, so I don't know if either/both of these options are actually available on this PC model. If not available, you could always use a standard USB3>DisplayPort or USB3>HDMI dongle for that extra monitor. Just make sure the dongle supports your version of Windows and the "recommended" (aka: "native") resolution of the monitor to be attached to the dongle.
Hi all, Does anyone know if the Dell Inspiron 5680 supports video output over its USB-C front port please? My setup for work is an Inspiron 5680 with an i7-8700 and a RTX 2060, but I have a multi-monitor setup using all the RTX 2060's ports already. I'm looking to also add a graphics tablet using HDMI - without needing to unplug one of the monitors if possible?  The other option I thought to try this week was using the HDMI port from the motherboard, however upon checking the BIOS I can't see any option to enable both onboard and discreet graphics at the same time. (But after checking the i7-8700 specs it does support onboard graphics.) Thank you in advance for any assistance or suggestions to make this possible.
