I just reformatted my hard drive so I’m sure that has to be the cause for this. I have an M17x alienware laptop with hybrid graphics and a Nvidia GeForce 9400M G and 2 GeForce GTX 280Ms. I have the hybrid graphics enabled but when I plug in my second monitor both screens go blank. I know the monitor isn’t the issue because the whole setup worked fine prior to the reformatting. The drivers for all the cards are up to date as well. I know the monitor is recieving some kind of signal because the screen goes from “No VGA Cable” to “Auto Adjusting” before the screen turns black. I also know the problem isn’t with the monitor because I looked into all the settings and stuff and none of it would’ve changed since my reformatting. Thank you for your time.
Do you have your drivers up to date?
According to the device manager. The Alienware support site is quite confusing.
