I also have this problem, but i am using the 945gm - version (22.214.171.12426) and I do not see the monitor option in the dropdown list for the primary device. I tried to set this in the display settings of the windows but was not able to, informing that I do not have the rights to change it.
Are there any means to solve this problem?
Hi Elemecca and Lian,
This is expected behavior for some computers. Some computer manufacturers will make the Notebook display the primary display at all times. This is something they configure in the Video BIOS which is integrated with the System BIOS. So this isn't set in the driver.
I'm not exactly sure why some OEMs do this. But you might want to check with your computer rmanufacturer if this is something they would consider changing....if they do, it would require a System BIOS update. However, I suspect they have good reasons to have done this.
Apologies for my temporary diappearance.
Robert_U is correct that the only device that appears in the "Primary Device" dropdown is "Notebook".
Per Rae's post, I assume that this is a restriction imposed by Apple. There is a further layer of complication in my case, since Intel Macs use EFI instead of a BIOS. In order to run Windows they then run a BIOS emulation layer. I don't know whether this limitation is imposed on all OSes or only those running under the BIOS emulator. I'll investigate. I will also see if there's a facility for me to ask Apple about this.
UPDATE: Apple does not have a support facility for this type of inquiry. Mac OS X allows you to switch the primary display but I can't tell whether this is done in hardware or software.
Lian: Just out of curiosity, what kind of computer do you have?
I'm using a Acer TM3040. It is a very old one.
