Dell Laptop External Monitor Not Working
Dual monitor setup not working. By EzrasMonkey. On Jan 25, 2017 at 17:38 UTC. General Hardware. Some of the Dell computers have an option to disable external monitors. If HP has the same option, she might have set it. You may also find that when they have used the laptop when it's not on the docking station and they dock it. I am trying to connect my external monitor (acer) using HDMI-DVI connector. System is not detecting another monitor. Tried F4, F11, Device manager - 6170798.
