I have an Acer Timeline 5810T laptop running Windows Vista 64 with an Intel Core 2 Solo U3500 and 8GB RAM, Mobile Intel 4 Series Express Chipset Family. I recently downloaded the new Intel graphics driver, 188.8.131.52.2869, which came with a new Graphics and Media Control Panel program. Under the "power" > "power features" there is an option to select "Display Power Saving Technology". To the best I can tell, this washes out the colors. People's faces, in particular, look badly airbrushed. I do not like the look of it.
I have turned this option off several times, but every time I reconnect the power cord, then disconnect, it reselects (forces) the option. I cannot turn it off. Any idea how to fix this? I have the feeling it will not let me revert to an older driver that did not cause this problem.
The graphics drivers we have available in our website are generic. We cannot guarantee those drives will work fine on every OEM system.
You can try uninstalling that driver from Programs and Features in Control Panel and then installing the latest graphics driver Acer provides in their website. You can use this link http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=1123
