Voyager2 not showing video
So I am testing my Voyager 2 with the HDMI-VGA adapter on a Dell Optiplex 7010. I am unable to get video going at all. I have also tried various HDMI to VGA adapter cables and even a Displayport to HDMI cable I have (that I know works). The Optiplex 7010 has 2 Displayport ports and a single VGA port.
My logs are at:
Please check. Thanks,

Thanks for reporting this! Sorry about the video issue.
The interesting line in the log is here:
Jan 03 21:48:25 tptest ustreamer: -- ERROR [635.614 stream] -- Unable to start capturing: Invalid argument
There have been a few threads where people have seen similar symptoms:
What's worked for other users:
- Restarting the TinyPilot
- Restarting the target server
- Reducing video resolution on the target server
Can you try restarting? If you're still seeing the same behavior after restarting both, is it possible for you to reduce the resolution on the target server?
It's also possible that using an alternate EDID could fix this.

Tried everything you mentioned. During a reboot of the host, I did see the boot menu for Ubuntu; but once it got past the boot menu, the "No Signal" returned. I noticed the same ustreamer error:
Jan 03 22:55:54 tptest ustreamer: -- ERROR [476.968 stream] -- Unable to start capturing: Invalid argument
I also ran:

I changed the resolution from 1920x1080 to 1280x1024. Still no joy.
I ordered this unit as a test unit because I have several users with Linux workstations that have encrypted storage. Because of the encryption they cannot remotely reboot their workstations. I was hoping this solution would be a low cost plug and play option. What is the return policy for this device?
Dell desktops are generally very cooperative with TinyPilot, especially if they're made within the last 10 years. It's possible this is a defective capture card rather than an inherent incompatibility with TinyPilot. Are you able to test TinyPilot's video capture on any other device that outputs HDMI?
It also could be an incompatibility with the VGA adaptor or DisplayPort adaptor rather than the Optiplex. From customer reports, VGA to HDMI adaptors generally work with TinyPilot, but this one definitely does.
If we're not able to find a solution, you can email firstname.lastname@example.org, we can work out a return or replacement with you.

I use these for my Optiplex 9020s and PowerEdge T30 (ESXi hosts): https://smile.amazon.com/gp/product/B00K2E4QJK/ They work well, even through a 4-port manual KVM.
Occasionally, I have had to move from one DisplayPort output to the other on the OptiPlex boxes in order for an image to display in TinyPilot.
