Is it possible to connect two external monitors to a Retina MacBook Pro without using Thunderbolt displays?

For example, one connected with HDMI and another using Apple's DVI connector and also use the screen on the laptop.

I have three DVI monitors attached to mine using adapter cables. –  asmeurer Sep 26 '12 at 4:42

Yes, that should definitely be possible, as both Thunderbolt ports are also mini DisplayPort ports and the other would be connected via HDMI.

Yes. In addition to the HDMI port, you can use either of the Thunderbolt ports as mini DisplayPort ports, just like all Thunderbolt ports.

Can you confirm both Thunderbolt ports can also act as mini DisplayPort ports - did you possibly try it yourself ? –  iolsmit Jun 20 '12 at 21:54

It's part of the Thunderbolt spec - all Thunderbolt ports have to act as mini DisplayPorts or they're not Thunderbolt. –  CajunLuke Jun 20 '12 at 22:07

I can confirm that both Thunderbolt ports on the MBPR are mini DisplayPorts as well. I discovered it by accident and was pleasantly surprised. :-) –  The Doctor What Jul 12 '12 at 4:02
    
@TheDoctorWhat I would be shocked if they weren't - all Thunderbolt ports are required to be mDP as well. –  CajunLuke Jul 12 '12 at 4:10

I can confirm this. I have three monitors connected and running in addition to the retina screen. two via the thunderbolt ports and one hdmi

However this caused my retina display to flicker.
