iMac (mid 2007) not detecting tv/display

My 2007 iMac, OS X 10.10.5 Yosemite, will not detect a second display. The option "Detect display" isn't even there, under the display preference pane. I have tried two different DVI adapters and still nothing. It can't be that outdated, can it?

iMac (24-inch Mid 2007), OS X Yosemite (10.10.5)
