Screen Resolutions issues.

Is there a way to tell grub to boot the os with a certain resolution?

I have acquired a big 200 lb, NEC P701 70 Professional Grade Large Screen. It has a pc built into it. There is a display when installing Bunsenlabs and Debian. I have a display up until just after grub goes to load the OS. After that I get:

Attention!
Signal frequency is out of range
Please change signal timeing
H: 0 kHz
V: 0 Hz

I have tried switch to any of the TTY's but I just have the above message I have tryed using all the options in the Grub selection menu (normal, recovery, TTY) still nothing.

I have not looked into trying to SSH into the system because I am not sure if Bunsen as ssh server running by default. I believe that is enable during the "BunsenLabs Welcome" Scripts. The other side of that is I wouldn't know what files to edit for screen resolution. I will explore this and see what I come up with.

Luckily I decided to use a different larger hard drive then what came in it and the screen displays what resolution it is running in for a minuite or two. I put the original drive back in and was able to get the following from it.

The screen seems to like the following resolutions:

The screen display this when Grub is on the screen.

Aspect: Full
640x 480
31.5kHz/ 60.0Hz

Got this from booting into windows.

Aspect: Full
640x 480
31.5kHz/ 60.0Hz

Aspect: Full
800x 600
37.8.5kHz/ 60.2Hz

Aspect: Full
1024x 768
48.3kHz/ 59.9Hz

Aspect: Full
1920x 1080
67.7kHz/ 60.2Hz

Thanks for any information that can be provided to get this going.
