Can’t get Vegas 15 to see external monitor
Hi. I have been using Sony Vegas for a few years now. My machine has Windows 7 Professional (64 bit) and I have a NVIDIA GeForce GTX 760 Graphics card. I have been using Sony Vegas 13 with no problem and that includes my main monitor connected with a DVI connector and my second monitor (used as my preview monitor in Vegas) connected with HDMI.
Today I upgraded to Sony Vegas 15 and everything works except that now Sony Vegas cannot see my second monitor. When I click on the “Video Preview on External Monitor” button nothing happens. I have right clicked to look at the “Preview Device Preferences” tab and have no ability to select a second monitor — no options for that appear.
What is odd is that Windows 7 Professional most definitely can “see” this second monitor. I can drag my mouse so that the cursor moves from one monitor to the other. I can even drag my opened Sony Vegas project to the other monitor and I can see it there if I so choose. Additionally, I kept Vegas 13 on my machine “just in case” and so have both Vegas 13 and my newly installed Vegas 15 on my drive. So I tried going back to the old Vegas 13 and it opened up just fine and when I clicked on the “Video Preview on External Monitor” button then my display goes to the second monitor without a problem. So, as far as I can see, the problem lies with Vegas 15 and not Vegas 13 or Windows 7. As it stands now, Windows 7 can see my second monitor, Vegas 13 can see my second monitor, and Vegas 15 CAN’T see my second monitor. Any suggestions please?
