Did you try to ask the software what it thought the monitor was? Curious
if this is a wierd interaction of software with an as yet unknown
hardware problem. For example, does anyone know how to use this? 

get-edid | parse-edid
This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 2
No EDID on bus 3
No EDID on bus 4
No EDID on bus 5
No EDID on bus 7
1 potential busses found: 6
256-byte EDID successfully retrieved from i2c bus 6
Looks like i2c was successful. Have a good day.
