My apologies. I had tried the Acer driver website and each download that seemed appropriate suggested that the basic program (1.0?) needed to be installed prior to downloading any particular update. I couldn't seem to find the base program for Intel Wireless Display.
More background info for you. I purchased Netgear "Push2TV" to connect my laptop with my TV. It requires Intel i5 430M processor which Acer has in this model. I can't seem to find the right download. Thanks for your help.
