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!

Hello and Welcome -

Here is what may be your answer (found at the Dell Laptop Forum) -


> after connecting a monitor to your laptop via VGA port you have to press either "F1" or  "F1" & "FN" to switch between internal,external,extend etc options.

> during boot up you have to press "F1" & "FN" to see the BIOS or Boot menus


> VGA monitors can only work within a certain range of resolution and frequency but usually cope very well with normal laptop screen settings.Unless you use more than 10 year old monitors you should be fine....


Thank You -
