I have a 13" MacBook Air (2012) and I would like to connect it to two external Lenovo Thinkvision monitors. Both monitors are identical. They have both a VGA port and a DVI port on the back (see photo).

I am not certain how the ports can be used properly to connect the two monitors together. What is the easiest way to use them both with a MacBook Air that has only one Thunderbolt port? Can I use a Thunderbolt to VGA adapter to connect to one monitor via a VGA cable and then use a DVI cable between the two monitors?

I would like to use both monitors without purchasing an expensive piece of hardware like the Matrox TripleHead2Go.

since they air only has 1 thunderbolt and some usb2 ports, you're pretty pinched.

you could get a thunderbolt dock along the lines of the caldigit unit.. this has an hdmi and a pass-through thunderbolt on it.

you can then get an hdmi-dvi cable for oen monitor and a thunderbolt to dvi adapter for the other.

another option would just be a thunderbolt hub. neither solution is very cheap, but it willg et you wht you want. there are also devices for usb-vga conversion, but that's a last resort, imho.

i'm curious how well these will be powered (how much resolution and how laggy) they will be, but it should work.

Venicejeff is right.

To expand, you can't daisychain monitors that don't have a thunderbolt port on them. DVI and VGA require dedicated inputs. So if you want those two monitors you will need an adapter that gives you another video port. Like a thunderbolt dock and some adapters or that Matrox unit that you mentioned in your question.

The only other option is one of the Lenovo monitors and the display built into the MacBook.
