W510 Display Issue / External / Display Port

Model:  4389-AN4

O/S:  Win 7 64bit

W Series Dock

DisplayPort Connection (also happens using VGA and or DVI)

BIOS:  1.27/1.32

Monitor:  Lenovo L2440x


During power up, power on password screen does not display.  Sometimes it does, sometimes it doesn't.  I've tried modifying the settings in the bios for which monitor it boots to first, and that doesn't seem to fix the issue either.


Sometimes I do get a display, but the screen looks horrible.  I've checked cables (even swapped them).


Suggestion?  We were able to recreate this on 2 W510's (same config).




P.S.  If I can provide any additional data please let me know.  I often just type in my power on password and eventually the monitor comes on and I get my windows log in prompt.
