PowerStrip follows the example of Matrox's venerable PowerDesk when it comes to custom timings: for each resolution, only one custom timing is allowed and it is either enabled or disabled.
However, if you want to switch among multiple timings for a single resolution you can do so by accessing the PowerStrip developers' API via standard Windows shortcuts and the command-line. Here's how*:
1. PowerStrip menu > Display profiles > Configure
2. Switch to the resolution you want to customize (if necessary)
3. Click "Advanced timing options"
4. Adjust timing parameters as needed
5. Click "Apply" button, and then click the "Copy" (to clipboard) button
6. Open Notepad and paste the timing from the clipboard - Edit menu > Paste
7. Create a Windows shortcut to PowerStrip, by reight-clicking anywhere on the Windows desktop > New > Shortcut
8. When the "Create shortcut" dialog box appears, click Browse and point Windows to the pstrip.exe file on your HDD
9. After the shortcut is created, right-click the shortcut on your desktop and select "Properties"
10. Append to the "Target" field the command-line parameter "/T:", followed by the PowerStrip timing parameters from Notepad, e.g.,
C:\Program Files\PowerStrip\PStrip.exe /T:1280,77,144,259,1024,4,3,54,181575,338
Repeat steps 4 thru 10 for as many timings as needed.
Note: The executable file name (with or without path) goes *inside* quotation marks, and parameters follow w/o quotes, e.g.,
"C:\Program Files\PowerStrip\PStrip.exe" /T:1360,104,120,216,1024,1,3,32,137250,340
*Update: Beginning with PowerStrip 3.42, a right-click on the copy-to-clipboard speed button in Advanced timing options will give you the option of creating a shortcut on your desktop with the correct timing parameters, so you don't have to mess with the instructions above. (This is the small icon/button immediately to the right of the Apply button.)
