Id like to find the phisical different between the two system board.
Where is the memochip for video card X600.
One is with 128MB the other is 256MB. Can I see the differnt?
Thanks
PS: Actually my replacement board company claim that the board is 374711-001 with 256MB grafic but my bios tell 128MB.
What is wrong the company or the bios?
HP probably isnt lying to you. the video chip they replaced, 374709-001, was 128 Mb chip, your new one is 256 Mb. When HP installed the new one, the most likely failed to update / reinstall the bios. If the bios was not updated, the computer would not recognize the extra 128 Mb of graphics, as graphics chips are not plug and play. If you provide me the model number of the computer i can link instructions on flashing the bios; However, i would call HP and see what they can do. ~gnomer

After upgrading to Leopard, installing a 500 giga external drive for effortless time machine backups, and a 2.0 gb ram expansion to 2.5, this week I connected an outside monitor to my iMac (a 20 inch Samsung 2043 NWX with a pixel resolution of 1680 by 1050).
It works great. Here is the problem: As my iMac only has display mirroring capabilities (it does not have extended desktop that is available in later models), I cannot turn of the built in display, nor can I toggle between the two.
There is a third party patch that claims it gives my iMac extended desktop, but I do not like to install third party patches on my iMac. Heck, at this point I'm not even sure that with extended desktop I could turn the internal display off to begin with.
The native graphics support card is quite capable: ATI Radeon X600 Pro graphics processor using PCI-Express and a maximum resolution of 2048 by 1536 pixels. The status shows it is presently supporting two displays simultaneously: One at 1440 by 900 pixels (my native iMac display), and another of 1680 by 1050 (my 20 inch Samsung).
I tried dimming the display but the control is disabled whilst on video mirroring mode. I tried playing with the internal monitor set up but I cannot set the display to zero using this option either.
Let me know your thoughts please. Best regards, Roberto A. Lovato
