External monitor not displaying on VGA or HDMI ports (Win7)
I have a Dell 15R N5110 that I want to connect an external monitor to. Monitor displays No Signal from both VGA and HDMI ports. Molnitor worked fine on Dell laptop running Win XP.
Once the system is connected to the external monitor did you press Windows Key + ‘P’ Key to project it to the external display? Also, try reinstalling the Video card drivers on the system.
