[qanda]This thread is about the Acer Aspire 5536. Click here to see full specs[/qanda]i have acer one laptop. when i plug the vga cable in the dell hd tv flat screen monitor my computer doesnt come up when i scan sources on the tv. i leave tv on vga and mess with display properties on laptop, settings, check box that says extend my windows desktop onto this monitor, hit apply, and nothing. i notice that when i hit apply the box reverts to unchecked. do i need to download a new driver?? if so where can i get one?

ATI uses a universal driver model for their GPUs.

You can try downloading the latest Catalyst suite, their is an option within the CCC window to force HDTV support (720p or 1080i/p) on unrecognized displays.

Do you have a function button on the laptop that switches on/off the second display.

Silly question, but is your TV set to the right input? Is there two VGA inputs?

Is there any settings in bios to set both displays as on?
