I added a Dell monitor to my laptop (duo core running Win7) in order to have a much larger screen space to work with. It worked however the color flickers every 15+ seconds or so! I made sure the proper driver was installed for this monitor (and it is), and I checked my connections (all good). I even unplugged the monitor and replugged it back in, rebooted twice and still the flickering occurs. The monitor is pretty much brand new as it has rarely been used. It came with a Dell system I purchased of which I already had a larger, better quality monitor for.
Thanks for any tips/help in getting this fixed!
