I have tested Miracast with Netgear PTV3000 (firmware 2.2.16) in 5 different computers running Windows 8.1 Preview. Miracast works with Samsung Series 7 All-in-One PC, but not in other computers.

Are there any device or driver requirements for Miracast in Windows 8.1? I am trying to project (duplicate) my screen through Miracast.

- Samsung Series 7 All-in-One PC (DP700A3D-A01US): Adding PTV3000 works and I can project my screen through Miracast.

- Lenovo Thinkpad X1 Carbon Touch: Adding PTV3000 works partially (PIN code is asked), but new projector is not added to device list and projecting does not work.

- Samsung Series 7 Slate (XE700TA-H01SE): Adding PTV3000 works partially (PIN code is asked), but new projector is not added to device list and projecting does not work.

- Acer Iconia W510: Adding PTV3000 works partially (PIN code is asked), but new projector is not added to device list and projecting does not work.

- Lenovo Thinpad W520: Adding PTV3000 works partially (PIN code is asked), but new projector is not added to device list and projecting does not work.

I have also noticed, that after partial addition of PTV3000 Miracast device, I have to go to the "old" Device Manager to remove the device. In Samsung Series 7 All-in-One PC in can remove the PTV3000 Miracast device from the "new" PC & Devices / Devices menu.

If projection is active during the removal of the PTV3000 Miracast device, the removal gets stuck and I have to reboot my computer in order to remove the device. If I stop the projection first, the removal works. Perhaps Windows 8.1 could automatically stop the projection when I want to remove the Miracast device from my device list.

Same question here on a Dell Latitude E6510

According to http://withinwindows.com/within-windows/2013/6/30/windows-81-features-miracast-wireless-display-tech-and-it-works-well computer hardware must support Miracast and you also need display drivers designed for Windows 8.1

Nvidia and AMD already have released Preview Drivers:

Intel HD Graphics 3000 or lower don't work yet. Intel HD Graphics 4000 (e.g. Lenovo Thinkpad X1 Carbon Touch) and Surface Pro should work.

Hi,

Thank you for your update. You can waiting these vendors to release the latest driver for Windows 8.1.

Regards,

Ok so i have an Intel HD Graphics 4000 and im wondering if i need a new driver or something? is there something i should be doing? where is the setting? what does microsoft call it? do i need to install or enable it?

Miracast just works, if you have correct driver+hardware.

Using Surface Pro + Netgear PTV3000 + Sony KDL-X3500 TV:

- open settings charm

- change pc settings

- pc & devices

- devices

- add a device

- select PTV3000 and enter WPS PIN

- if you see a new projector in device list, adding succeeded. Otherwise adding failed and you have to remove ptv3000 from "old" device manager's software devices

- open devices charm, select project or play
