Q: Blank (black) screen during booting

Hi! Last week I bought a new Mac mini (late 2014) and connect a monitor to the Thunderbolt port via DVI-to-minidisplayport converter. And everything works well except that I can not see anything on screen until User selection screen. As result I can not use single user mode, boot selection panel, etc. How to fix that?

Mac mini, OS X Yosemite (10.10.4), Late 2014
