Hmmmm ....
OK. Let's go through some details. Then I will try to find a write-up somewhere else ..
Ignoring my "extra" monitor (my 3rd.)
I have my Dell 20inch wide screen set up in the center (size 1050x1680), my Sony 21" Trinitron CRT off to the right (1200x1600). The Dell is on DVI, the Sony on VGA (CRT) connction. They are on seperate cards - Dell on a Radeon, Trinitron (both Trinitrons actually) on a Nvidia GeForce. I assunme there is a motherboard video chipset that is not used - should be disabled in BIOS (see below.)
I am on a PC running Windfows XP Service Pack 2, 32 bit. Photoshop CS2.
If I "right click" on my dresktop, under Properties->Settngs, I have "Use this device as my primary monitor" and "Extend my windows desktop onto this monitor" both checked for tthe Dell in the middle on DVI.
On the Trinitron., only the second bocx, "Extend my windows desktop .." is checked.
I am already set up on 2 monitors, but I'll try to undo and "redo" it.
Open Photoshop. With Photoshop half sized (not minimizerd or maximized), I can drag it to either monitor.
Size it to fit one of the monitors. Click the top bar to "maximize" the window. It fully fills the monitor with no "overhang." This works the same on either monitor.
When I movbe the Photopshop window, the tool palette and other small windoiws that I havce open - Info, Actions, Layers -0 stay behind on teh previous desktop.
When I open a file in Photoshop, it opens half size - neither minimized or maximized. I can easily pull that onto either monitor. It moves very quickly and freely. I can also have it "straddle" two monitors.
When I cvlick on it, it maximizes to fill the monitor for whichever "side" it is on.
Question: When you go into Properties->Settings (ertight cloicvk on teh desktop) and have it identify teh monbitors. does it identify both as you would expect?
No extra active moniotors? (that don't correspond to any phjysical monitor?)
Are you using 1 video card, or 2 sepoerate cards? There is a section on the "troubleshoot" series of questions (under Properties->Settings) about your BIOS setup and the order of teh cards. Yoiu might have a look. You can see the details of your card in "Device Manager." This is what I gwet:
Radeon: PCI Slot 10 (PCI bus 1, device 0, function 1)
Nvidia: PCI Slot 3 (PCI bus 5, device 2, function 0)
From Windows Troubleshooting:
When you install your display adapters, check the following:
Your primary display adapter should be installed in the Peripheral Component Interconnect (PCI) slot 0 or 1. This slot is usually the farthest from the Industry Standard Architecture (ISA) slots and nearest the edge of the motherboard. This display adapter should be connected to your primary monitor.
If you are using both PCI and Accelerated Graphics Port (AGP) display adapters, the PCI display adapter must be installed in the first PCI slot on your computer.
Note
If you have an AGP display adapter and a PCI display adapter installed, most computers select the PCI card as the primary display adapter because the PCI bus is enumerated before the AGP bus. This enumeration is a function of your computer's BIOS and is not controlled by the Windows operating system.
To use an AGP card as the primary display adapter, and a PCI card as the secondary, one of the following conditions must exist:
The computer's BIOS must support the enumeration of the AGP bus before the PCI bus.
The PCI display adapter must have the option to disable VGA functionality at the hardware level. Check the documentation for your PCI display adapter for information about disabling VGA functionality.
Can you use multiple display support when your display adapters are correctly positioned on the PCI bus?Yiu might check in general taht your BIOS is set up correctkly, WEhen installing some video cards, you need to diasble soem of teh BIODS video card default mpotherboard capability OI be;ieve. A little hazy on thios - it has been 3 years since I had to do that to install a second monitor on another machine.
Can't reboot my machine toi check my BIOS setting swhile writing this. Here ius a bit of an "article" on thsi:
