Q: Connecting HDMI takes out one of my monitors.
I have three monitors - one Apple Cinema Display and two DVI monitors. When I connected a cable from the HDMI output (to a receiver) I do get a picture on the TV, but one of my DVI monitors is blanked out.
None of the monitors is Thunderbolt/Displayport so they are using adapters. Is that the problem?

Make sure you don't have more than two displays on one Thunderbolt bus. The HDMI port is on the same Thunderbolt bus as the bottom two Thunderbolt ports.
