U2723QE, DDPM, Command Line (CLI) syntax, PBP Mode?

Question

Hi everyone! Recently got a U2723QE and was excited to use the CLI to switch some monitor states. I'm finding some commands work, some do not. I'm wondering if syntax is an issue. The documentation is as follows: /Applications/DDPM/DDPM /1:WritePxPMode Off This turns the current PiP off. I would expect one of: /Applications/DDPM/DDPM /1:WritePxP PBP USB-C HDMI /Applications/DDPM/DDPM /1:WritePxPMode PBP USB-C HDMI to turn on PBP with USB-C on the left, and HDMI on the right. However it doesn't work. I have also tried 'split' in place of PBP. Here is Dell's documentation from the DDPM folder: ==============================================Dell Display Peripheral Manager==============================================Support Mac:Mac 2018 or above.Support OS:macOS 11 or above.Setting Up:Connect your Mac to monitor by display cable or USB upstream cable. Dell Display Peripheral Manager uses DDC/CI channel to communicate with your monitor. Ensure DDC/CI is enabled in the monitor On-Screen Display (OSD) menu.Grant Security Permission: - Requires Accessibility privacy permission to allowDell Display Peripheral Manager for Easy Arrange andEasy Memory functions.- Requires Automation privacy permission to allow Dell Display Peripheral Manager for Easy Arrange and Easy Memory and Command Line functions.- Requires Camera privacy permission to allow Dell Display Peripheral Manager for camera preview.Troubleshooting:If Dell Display Peripheral Manager is unable to detect and/or communicate with a supported Dell monitor, please take following actions to troubleshoot:- Make sure the video cable or USB upstream cable is properly connected to your monitor and your computer. Ensure all the connectors are firmly inserted into the ports.- If connecting HDMI cable not working, switch to use HDMI and USB upstream cable. Launch DDPM again.- Check the monitor OSD to ensure DDC/CI is enabled.Input Manager-----------------------------------------------The Input Manager tab provides convenient ways for you to manage multiple video inputs connected to your Dell monitor. This makes it very easy to switch between inputs while you work with multiple computers.Easy Arrange-----------------------------------------------Easy Arrange tab simplifies the applications window organization on the monitor.Window Snap-----------------------------------------------Application Window Snap is designed to enable application placement on any screen quickly. When the application is on the connected monitor, dragging the application triggers easy arrange flyout menu, you can drop the application to any of the recently used layout quickly.Auto Mode-----------------------------------------------Dell Display Peripheral Manager automatically switches to the corresponding Preset Mode whenever the associated application is activated.Shortcut Key-----------------------------------------------Enable combo keys to make actions such as calling up DDPM, Easy Arrange, Window Snap, Favorite input...etc.Power Nap-----------------------------------------------You can choose to set the brightness of the monitor to the minimum level, or to put the monitor to sleep when the screen saver is activated.Command line Interface that DDPM supports-----------------------------------------------A rich and flexible command language is supported via thecommand-line, and command-line arguments can be combined.Where appropriate, a specific display can be targeted byprefacing the command with the enumerated display number, e.g., '2:AutoSetup'; if the enumerated number is not specified the command will be applied to the current selected display or to all displays, as appropriate. Commands include:WriteActiveInput [DVI2/HDMI/DP2,etc] - switches active inputReadActiveInput [DVI2/HDMI/DP2,etc] - switches active inputRestoreFactoryDefaults - restores factory defaults*AutoSetup - executes an autosetup (analog only)*ReadColorPreset - read the current color presetWriteColorPreset - set the color presetRestoreLevelDefaults - restores level defaults*RestoreColorDefaults - restores color defaults*WriteBrightnessLevel X - sets brightness to X% (0-100)*ReadBrightnessLevel X - sets brightness to X% (0-100)*WriteContrastLevel X - sets contrast to X% (0-100)*ReadContrastLevel X - sets contrast to X% (0-100)*WritePower [on/off/standby] - sets the display power mode (standby should be used for central control.)*WriteOptimalResolution - switches to optimal resolutionWriteEALayout [X] - changes Easy Arrange grid type to X (0-48) where 0 is to turn off EA layoutRescan - rescans display hardwareReadControl X Y - sets hex control X to hex value YWriteControl X Y - sets hex control X to hex value YIncreaseControl X Y - increases the value of control X by YDecreaseControl X Y - decreases the value of control X by YWritePxP [Off/PiP/PBP Main Sub1] - Change PIP/PBP settingsWriteSubInput[DP1, DP2, HDM1... etc}]- Change the subinput SwapVideo - Swaps the main (primary and sub inputs between 2 PCs)SwapUSB - swaps the usb inputs on the main and sub inputs (for 2 PBP mode only)Zoom - switches between PxP and fullscreen modeExit - terminates the program=======================================================================History=======================================================================20230614 - 1.1.1.0033- Improved device discovery performance and reliability. - Fixed DA310 connection issue when using HDMI and USB upstream cable causing DDPM detection intermittent failure and monitor showing black screen issue. - Fixed localization translation error and UI truncation text on Spanish language. - Fixed monitor rotation of a monitor causing the other monitor rotated issue. - Fixed Input Source hotkeys written incorrectly for favourite input and swap two inputs of PIP/PBP windows.- Enable span across multiple monitors when connect to 2 monitors on M1 system. - Support M2, M2 Pro and M2 Max DDC/CI.- Improved Easy Memory application handling and arrangement.- Update SDK v4.0.1.13- Solve DDPM high CPU in some use cases- Fix DDPM crash when click 'Restore saved windows layout' - Fix non-M1 installer DDCCI connection20230327 - 1.1.1- Add webcam selection in Personalize- Fix camera setting file access privilege issue using standard user account- CLI enhancement- Solve Easy Arrange and Easy Memory known issues- Support MMS status bit in OSD Cloning- Solve U2723QE DDPM crash issue- Solve U2722D limited SW mode issue- Solve U3421WE USB switch shortcut key cause DDPM searching issue- Solve U3223QE timing delay- Solve M1 DDPM cannot connect U2422HE and U2421E - Support new display models- Solve large format display VGA connect fail issue- Update SDK v4.0.1.10

So apparently the documentation is incorrect. /Applications/DDPM/DDPM /WritePxP pbp-2v-fill works.  The other pbp options do not.
