After Login Screen, Black screen with white cursor only

Hi there, I hope everyone is well.

I have a strange issue that started happening recently. System restore doesn't help as it happens with multiple machines.

I have a lobby display running from TV via HDMI to EXTRON to Ethernet and back again to the computer in the server room. I have had this setup for a little over a year now working just fine. We recently got a new computer (We lease) for the lobby display and after setting it up, I only see a black screen with a white cursor. I have troubleshot this a little too much that I am now not sure if it's a windows update, video card update, or possible the EXTRON. However, when hooking up a laptop it works just fine as it should.

Please note that I can see post boot and the CTRL ALT DELETE screen just fine, but once logged in I just see cursor. If someone moves cursor I can see it from the lobby display. If I uninstall the video card driver I see everything perfectly fine but when running presentation it's not focused for obvious reasons, so I can't leave it like that.

I have used a Desktop with AMD and latest drivers as well as down graded drivers, issue still is present. I use an older nvidia card FX570, same deal with drivers, still the issue is present. I use a new computer with a new nvidia card, and it works. but unfortunately we do not have any of those available and that's a really expensive machine.

here is where it gets even more strange;
If I hook the computer up directly to the TV and not behind the extron device, it works, both with AMD and nvidia. As of right now I have a laptop running behind the extron and it's displaying just fine.

OS: Win7 and Win10 have been tested on.

Can anyone help me with this or give me some other troubleshooting suggestions? I am at a loss and definitely need help!

What is the make and model# of the EXTRON?
Is it possible to take the EXTRON out of the mix and attach the screen via a long HDMI cable directly to the computer?
Other then that, you are going to need a video driver designed for the EXTRON.

There is not enough evidence pointing to specific driver for EXTRON. I would agree with you but it works with certain computers, not others. I have already connected directly without EXTRON and it worked. I have down graded the drivers to the version that was on there previously when it was running for the year solid without issue, but the problem is still present.
