View source for How to Fix Monitor Outputting "OUT OF RANGE SIGNAL, CANNOT DISPLAY VIDEO MODE"

===Ubuntu 16.04===
This issue came up when connecting a VGA cable to our new Ubuntu 16.04 server.  

Full Error Message: 

  1: Auto Detect (Analog Input <VGA SYMBOL>)
  OUT OF RANGE SIGNAL
  CANNOT DISPLAY THIS VIDEO MODE, CHANGE
  COMPUTER DISPLAY INPUT TO 
  1680X1050@60Hz

I couldn't change the video display input because I had no way of seeing what's happening because of this video output error.  

To resolve. 

1. Get an Ubuntu Server 16.04 USB boot disk and plug it into the server <br />
2. Make sure BIOS has USB boot disk at a higher priority than the HDD/SSD. <br />
3. At options menu of the USB boot disk, select "Rescue a broken system" <br />
4. Go through all the menu options selecting defaults until it asks you what to mount for root.  Select the root partition from the HDD/SSD, not the USB disk. <br />
5. Select the option for starting a shell. <br />
6. While shell is started, mount the boot partition @ /boot.  command for me was: 
  $ mount /dev/sda1 /boot
7. Edit /etc/default/grub and uncomment section that contains: 
 #GRUB_GFXMODE=640x480
8. Lastly update grub with: 
 $ sudo update-grub
9. Reboot and it should output video
