Question Using desktop monitor same time as Laptop

My friend's bro just got a new Alienware laptop and we are trying to get his desktop monitor to display the same thing the laptop monitor is displaying, so that we can spectate while someone plays a game or something.

We can only get one at a time to work though by using Fn+F4, but not both.

Any ideas why both won't display at the same time?

Send a message via AIM to the yellow one

what video card do you have, you can dual output and sync the same screen, or you get a box that can do another output not directly form the video card.

I am the yellow one.

I don't know, not my laptop.

We don't want to dual output though, just use the laptop screen and an extra monitor to display the same image. They do it on campus all the time.

It depends on what graphics it has, most likely either ATI or Nvidia...

There should be an option in the display settings which allows you to clone the primary display. Once the secondary monitor is connected to the laptop, look for a setting like this.

|Desktop PC| |Macbook Air 13" (Mid 2013)|
|Windows 8.1 Pro (x64)| |AMD FX 4100 Black Edition 3.6 GHz @ 4.0 GHz OC| |Arctic Cooling Freezer 13 PRO| |Gigabyte Nvidia GeForce GTX 560 Super Overclock 1GB| |ASUS M5A78L-M/USB3 Motherboard| |Samsung 840 Pro 256GB SSD SATA III HDD| |Kingston HyperX 8GB PC3-14900 DDR3-1866| |OCZ ModXStream Pro 700W Modular PSU| |NZXT Vulcan Micro ATX Case|
