I have a Dell U2212HM and just recently bought a new Dell S2240L and attempted to go dual screen. The U2212HM has DVI, and the S2240L has a VGA. When I try to detect the S2240L, it displays the message that no other monitor was detected. The S2240L has an HDMI slot as well, but that doesn’t work either.
My computer has 2 DVI slots and one VGA, the S2240L has 1 HDMI and 1 VGA, and the U2212HM has a DVI and a VGA. Am I doing / connecting something wrong? Or do I need an HDMI –> DVI converter? How do I get the S2240L to work?
