I have a Lenovo T530 laptop. When I connect an external moniter, it detects moniter for a second and then does not detect. The screen is detected then lost repeatedly so both displays keep blinking on and off.

What could be the cause of this?

What drivers are you running? Do you have the T530 with the optimus nvidia or only integrated gfx? – nerdwaller Feb 4 '13 at 16:43
