Hello,
A few days ago, i update the system to the latest version 10.10.3, after that my external display stop working, the display is conected through mini displayport, i check the cable it was fine, the port in fact it's functional by an HDMI mini displayport, i bought another DVI mini displayport and don't work at all.
Anyone has the same issue? if solve it, how you do it?
Thank you
iMac, OS X Yosemite (10.10.3)
Hi there themusicgap,
Welcome to Apple Support Communities.
From what I gather, you aren’t seeing any video on your external display since updating your iMac.
The article linked below provides a lot of great information and troubleshooting tips that will resolve most issues with video on external displays.

Hi Jason, i fix the issue, the system only recognize HDMI connection, then i had to buy an mini displayport to HDMI and a HDMI to DVI cable, and that's how i fix it, i think the latest update apply some restrictions to old connections, it's a shame by apple force the users to upgrade they devices...
After update to 10.10.3 Os X Yosemite don't detect my DVI display
