dual monitors - primary screen stays dim (Toshiba Tecra M5)



  • Forrest Smith

    Assuming the display is dim, but not off -

    Does the device have other brightness keyboard shortcuts printed on it ? On many machines the original brightness short cuts meant for Windows work.

    You might also try closing the lid and then re-opening while connected to VGA monitor all along. It should go into 'docked mode' , and then potentially when you open it the display will reinitialize with normal brightness behavior .

    thx, Forrest, for the quick response.

    Closing and opening the lid didn't solve the problem. The machine just didn't even resume when opening the lid again. Both displays stayed black.

    But I found the solution in the BIOS. I've changed the display settings from 'auto-select' to 'LCD+Analog RGB'.
    Now both screens are bright and the brightness slider works when hitting F6/F7.
