Hello jollyrogers,

which version of WinCC you are working with?

I just took a look at V7.0 SP3 OS-Project Editor and found available resolution of 2560x1600.

Doesn't this fit to you?

If found and older thread in german forum with a description how to get a newresolution at your own. It's a lot of (german) text and unfortunately I don't have time to translate it all in detail to you at the moment. So I try to give you most important info in english:

Translation of most important info of older thread

1) Create a new folder in installation path of WinCC ...\options\PDL. You have to add at the end of the name some of the following letters

SingleUser Project- Standard = SIMATIC_1920x1200

Multi UserProject = SIMATIC_1920x1200

Multi UserProject- Server = SIMATIC_Server_1920x1200

Multi UserProject - Serverview = SIMATIC_1920x1200_S

Client Project- Standard = SIMATIC_1920x1200_M

Client Project - Serverview = SIMATIC_1920x1200_MC

2) Copy data of an already existing folder into this new one and adapt name of cfg-file.
3) Open cfg-file with an editor and change parameters. Picture sizes, too.
4) Adapt *.pdl (Size Position, etc.)
Now you should see new resolution in OS Project Editor.

Hello

you can customize the screen with the screenwindows for the picture tree container. Here you can use the property for "Adapt Picture" to strech the screen.

Of course you can also change the PT screen itself but this could be more complicated and would be overwritten by generating the PT Manager
