Details:

When I boot to GNU GRUB on a dual-monitor Dell Optiplex 990, and it displays
on both screens, then when I cursor to select the desired boot option, the
apparently selected item differs between the two screens.

Expected result: Either the two monitor contents are maintained in sync

Acceptable alternate result: GNU GRUB only displays on one of the two
monitors. The other monitor is blank or displays just the background color.

Details:

GNU GRUB 2.02-beta2-9ubuntu1.7
Dell Optiplex 990 with dual Dell monitors

Boot options:

Ubuntu
Advanced Options for Ubuntu
Memory test (memtest86+)
Memory test (memtest86+, serial console 115200)
Windows 7 (loader) (on /dev/sda1)

Default on boot is set to Windows 7 (loader) (on /dev/sda1).

Steps:

1. Restart computer
2. Wait for GNU GRUB to display

Actual and expected results: Both screen show selected as:
Windows 7 (loader) (on /dev/sda1)

3. Press up arrow key once

Actual and expected results: 
Both screens show selected as:
Memory test (memtest86+, serial console 115200)

4. Press up arrow key once

Actual result: 
Left screen shows selected as:
Memory test (memtest86+, serial console 115200)
Right screen shows selected as:
Memory test (memtest86+)

Expected result: Both screen show selected as:
Memory test (memtest86+)

5. Press up arrow key once

Actual and expected results: 
Both screens show selected as:
Advanced Options for Ubuntu

6. Press up arrow key once

Actual result: 
Left screen shows selected as:
Advanced Options for Ubuntu
Right screen shows selected as:
Ubuntu

Expected result: 
Both screen show selected as:
Ubuntu

7. Press ENTER

Actual and expected result: Ubuntu launches
