When I connect an external monitor to my new Vostro 5480, I get an excellent picture on the external monitor. However, the laptop LCD, blacks out for a second and comes back up as blurry.
Disconnecting the external monitor removes the fuzziness from the laptop LCD.
I have had a Vostro 5470 and just recently upgraded - I have used this setup with the 5470 before without any issues.
I have all latest drivers for all hardware. No issues in device manager.
What gives? Thanks.
