Windows 7 - Hardware acceleration

I recently changed my hardware acceleration and lowered it to the lowest option. Now I want to change it back to the original settings that it was on, how can I achieve that?

When I go back to screen resolution->advanced settings->trouble shoot the change settings button is not clickable, so therefore I cannot change the settings.

If there aren't any possible ways, is there any way I can just put my laptop screen back to default settings

any thoughts?

Between you disabling hardware acceleration to you wanting to enable it again, have you updated the drivers for your GPU? The latest drivers might have changed it, so you can only change it from within the graphics control panel.

i'm not sure about for GPU but for windows 7 yes I have gotten the new updates
