unable to use external monitor on new PC

Hi,
This is my first time posting a question.

I was wondering if anyone else has had issues with latest Intel hardware preventing the use of video preview in an external monitor?

I recently upgraded the hardware in my main PC and now when I attempt to display the preview on a second monitor, I get only a black screen. Furthermore, I cannot close the preview window without forcing the entire program closed. I have compared all of the preferences between the old machine and the new and there are no differences.

Old PC -> New PC
Intel i7-2600 -> Intel i7-6700k
Asus Z-87 Deluxe Mobo -> Asus Maximus VIII Hero Mobo (Z-170)
16Gb DDR3 RAM -> 32Gb DDR4 Ram
256Gb SATA SSD -> 256Gb Samsung 950Pro M.2 (NVMe)
2x 4TB Hybrid HDD -> Reused
ASUS GTX780-DC2 Graphics card -> Reused
2x1080p Monitor + 1x 1440p -> Reused
Windows 10 Pro -> Same OS/Clean install

Nearest I can tell is that Vegas Pro doesn't like some of the new hardware such as the Skylake CPU (which has a new iGPU but is disabled), Z-170 chipset, or DDR4 Ram.

Thank you for any insight.

Are all monitors enabled and set as extended dektop in Windows?

yes, they are.

Did you select the second monitor as your preview under preferences? Sometimes it defaults to something else.

I assume you did a fresh install?

Gigabyte GA-HD170MB plus i7 6700K runs two screens OK this end. Screen 1 on nVidia card, screen 2 connected to the intel on board graphics. ( needs to be set up in bios).

Some of the intel graphics drivers will not provide quick sync seems OK. 4300.

This particular motherboard disables the integrated GPU when a PCIe board is present. There is no means of enabling it.

The preview window does actually open on the selected monitor, just no video. And the window cannot be closed without closing VP.

I know this works with this exact graphics card/driver version as it was working in the old machine.

I may yank the Nvidia card out and try VP with only the iGPU. At least that will indicate whether this is a GPU issue or something else.

Yes, this was a bare metal Windows install. everything was installed clean.

I have uninstalled/reinstalled Vegas Pro multiple times with the same result. Same with QT.

After a bit of experimentation I have found that the preview will work only if the selected preview monitor is the monitor selected as default in Windows.

It's not an ideal workaround but at least I can finish my damn video now. lol.

This problem did not exist on my old PC. My monitor arrangement is exactly the same as it was prior to the upgrade (one 1440p flanked by two 1280p monitors on either side. The center being the default). I've always been able to run the main program on the larger center screen and preview on the 1080p screen.

I'll be upgrading my GPU to a GTX980Ti next month, hopefully that will get things back to normal.

Why are you upgrading to Nvidia card when it's very clear that it isn't properly supported by VP? Currently AMD 290X or Fury X is a much better choice.

Edit:
Sorry, forgot you are a first timer in this forum. Do a search in GPU acceleration and you will find plenty of threads about the topic. Nvidia is not the way to go.

Thank you OldSmoke
I understand Nvidia is not well supported in Vegas Pro but for gaming, which is my primary use for this machine (I make gaming videos/machinima), I have not had good luck with AMD.

It appears that I am faced with a choice either to build a dedicated workstation for VP or find a product that has better support for Nvidia. The latter is something I'm not particularly fond of since I like Vegas Pro for the most part.

I am not gamer and still not a friend of AMD but I must say they have improved. If not Vegas, I would still use Nvidia.

I'm no gamer, either and I've never been a fan of AMD video cards. I have been pleasantly surprised by my experience with the R9 390 I got in December. No issues, whatsoever with any other apps and great timeline performance improvements in Vegas. Knock on wood.
