I have a computer running an AMD FirePro w600 with six 24" monitors.
It's been working great for about 4 years.
A couple days ago the hard drive died, so I replaced it.
I installed the latest version of Win10 Pro.
I didn't have to load any drivers for the w600.
I set it up and everything worked. All the monitors fired up and I only needed to adjust the order of the monitors to match.
The next day, one of the monitors is running at 25% the resolution of the rest of the monitors.(which are at 1920x1200).
When I try to change the resolution, the resolution choices are grayed out.
I double checked the connections. No luck.
I download the latest AMD driver. No luck.
What happened between yesterday and today, and how can I fix it?
