For anyone still looking for a solution on this, I love how they tell you to check with your video card manufacturer about an updated driver. And how are you supposed to install said downloaded driver when nothing is shown on the monitor?
For most, that's going to be a huge problem. So glad that the compatibility scan took that into account before the upgrade started and told me everything was fine and to go ahead.
For those who have set up a remote access program like TeamViewer, that might be your solution. I thought my upgrade install had frozen and failed as I had no signal on any monitor I plugged into the video card. However, I noticed on our laptop that the
upgraded desktop that was black screen was showing up as connected on TeamViewer. I connected to the desktop from the laptop and was shown a square screen with the Win10 upgrade welcome screen. Connected remotely, I finished the steps of the install. I
tried to change the monitor configurations, but nothing was being detected at all. It just showed I had one generic monitor and that was it, the screen of which was only viewable through the remote connection. Neither of the physically connected monitors
is receiving any signal.
I'm guessing that the plugged-in video card needs a driver update, so, hopefully that will resolve this. Desktop box is in the home office my wife uses, so, this will be a weekend project, but hopefully either plugging in a VGA to the port that's off the
motherboard rather than the video card will give me something to see. Otherwise, I guess I'll just be logging in and downloading the driver update remotely via TeamViewer.
Still hoping this hasn't been a huge mistake and that I can resolve the driver issue. Was just worried that Win 7 support would go away soon and I'd have to end up paying for Win10 at that point.
