Don't you worry - there are many, many ways for GPUs to inject ads :)

Of course you'll first have to dismiss the ad injected by your monitor manufacturer, but before that you'll have to dismiss the ad injected by your mouse manufacturer (or keyboard if you prefer that). Whoops, looks like your OS ads refreshed - drink another verification can! Just in time for your ISP to inject ads. But to dismiss them, first you have to dismiss the ad injected by your mouse manufacturer.

Oh look, another GPU ad! I feel lucky that all these companies want to provide me with the best information about new products and services.
