Hi Craig. Thanks for your reply.

I just verified in Device Manager that the Magewell driver for the Pro Capture Quad HDMI is 1.3.0.3214.

I changed the HDMI cord running from the Dell computer into input slot #3 instead of #1.

I did the same steps... Opened a new document in Wirecast. Added the Dell shot followed by the Sony camcorder shot in a separate layer. Then I added the Remote Desktop Presenter and doing that triggered the Dell view to flip again.

I just downloaded the latest video card driver for the Dell machine and retried the entire solution by shutting all machines down and starting fresh. Same thing happens.

Thanks for your continued help!

The Sony camcorder shot is not affected at all. It is constant and doesn't change in terms of resizing or flipping...

I noticed yesterday during a live streaming event that the Dell source also will rapidly flip 180° (three or four times a second lasting approximately 10-15 seconds) *even after* I have adjusted the shot to properly display. This happens intermittently with no predicatability or known ways to replicate it happening.

CraigS How specifically do you want me to test that? I added a Screen Capture using full screen then I tried using just a portion of the screen. So far, I don't see anything like the flickering or flipping as the Dell HDMI input. Thanks.

CraigS Yes. I have an Alienware machine. I'll check when I get back to the studio... about an hour. Thanks.

CraigS I can confirm that the problem is not limited to my Dell machine. It also happens when I plug an HDMI source from my Alienware machine...

Note I tried two more things:

1) I reverted to the Magewell driver release before the current (1.3.0.3214) one. I installed the driver 1.2.0.3003 (dated 8/4/2016).

2) I then added the Alienware HDMI to a new Document in Wirecast Gear/Wirecast Pro then added the Remote Desktop Presenter iMac source. Same result, 180 degree flip.

3) I then shut everything down without saving changes, installed the up-to-date Magewell driver (1.3.0.3214). Shut everything down again and restarted. Then I tried adding the Alienware source, followed by the Remote Desktop Presenter source. Note at this point I also tried adding the Dell source and it's also flipped. This would *seem* to rule out the Magewell drivers as the root cause I would assume?

Also, I have tried adding the Remote Desktop Presenter shot *first* to see if that would help. Same results, flipping the HDMI source(s).

Thanks for your continued help.

CraigS I filled out the Wirecast Support Form and sent it in to the engineer per your request... I included the link to this thread. Thank you all for your continued help!

CraigS Nothing as of yet.

CraigS This is a Dell desktop... It's an Inspiron 2350.

The Alienware machine is a desktop as well. It's an Alienware Alpha R2.

The monitor resolution is set to 1920 by 1080 on both machines.

I just replied to the engineer's email... I did try using the previous version (2.0.7 per the setup file he sent me) of Desktop Presenter on the iMac. I also updated Wirecast to 7.3. Neither of these tries fixed the issue. 

CraigS All monitors involved are set to 60Hz. Always have been throughout the duration of the problem.

Thanks.

CraigS Interestingly enough, I just opened a new Wirecast document. Added source 1 (the dell computer), source 2 (the Alienware computer), source 3 (the Sony camcorder), and then I added an additional shot that I haven't tried before... An Apple TV.

I then added the remote desktop presenter shot from the iMac. The Dell and Alienware shots flip/flicker 180°. The Apple TV shot does not.

An interesting development. I don't know what this means, but maybe this info will prove helpful somehow to you all.

Thanks again!
