I suggest you to review and complete the troubleshooting steps in the wizard guide here:
If the issue persists, visit the following URL and use the driver posted there for your controller:
Be sure to install the inf monitor drivers for the monitor connected and update your system BIOS too.
Thanks. The driver you directed me to did solve the problem.
I had seen the Intel info about that driver previously, but didn't try it out as I thought that it was addressing a different problem. The description for that driver referred to it as a solution for when resolutions like 1920x1080 weren't showing up in graphics properties. In my case, 1920x1080 was being listed as a choice, but it wasn't displaying properly when it was selected.
Regardless, I have now intalled that driver and the display is working correctly in 1920x1080, so thanks!
