However they do still work. Just start tapping the key as soon as you power on. If you wait for the Dell logo you most likely will be too late. That's how it works for me.http://en.community.dell.com/support-forums/desktop/f/3514/t/19469912
so maybe start tapping as soon as you turn it on ???
this looks interesting about the monitor and hdmi ??http://en.community.dell.com/support-forums/desktop/f/3514/t/19501356
maybe this as well??
