Let me go out on a limb here and generalize. Please place blame where blame it s due. It is NOT the SP2/3. That is only showing you what HAS happened, not what is causing it.
IF you are using a hub or any USB-based attachment for connecting to the outside monitor it will almost certainly be using DisplayLink drivers. So, updating the Intel drivers will achieve nothing.
Please note also that the Display Link drivers will use heaps of your internal SSD finite wear life. For external monitor use, ONLY the DVI and suitable adapter (if needed) is the ONLY option. Then you, like me will have ZERO problems with the external monitor and you can then lay the blame where it is due.
Use something like Process Monitor to watch the amount of writes to the SSD by the DisplayLink driver, then go buy a DVI cable adapter.
