I have an HP DV6-6047cl Its an I7 sandy bridge laptop with HD 3000 and Radeon 128 bit HD6770 1GB discrete DX 11 graphics. 8GB ram 180 GB intel SSD with a 750 GB hybrid Seagate HDD in a caddy in the dvd tray. The original mini wifi card with Bluetooth was a Broadcom ralink wireless N I think. Anyway the bluetooth was always flaky so I pulled it out and am using a generic bluetooth usb dongle. However I would like to have WIDI display. I read that you must use a card listed in the DV6 Service manual. There are three listed that meet the Intel Spec for WIDI Display N1000, Advanced N 6150 w Wimax or N6230 these are all Centrino. I found them on Ebay. Which wouldb the best for Wirless display?
