Wincc Comfort V11 Download
Rocki Stenger
I have a TP1200 Comfort panel. I just got V15 and a new computer. The computer has a screen resolution of 3240 x 2160. I have the computer's screen resolution set to the default and the font size set to 100%. The screens in the WinCC software does not match what is downloaded to the HMI.
Yes I have performed a rebuild-all of the HMI.
I have found a setting that is kind of working. I have the screen resolution set at 1920x1200 and the text is at 100% (Windows 10 computer). If I leave the font at Tahoma 17 bold then it is very small on the HMI. If I change the font size OR change the font and then compile, then it is scaled correctly, or at least much better than it was. If I then change it back to Tahoma 17 bold it is scaled correctly. But for some reason I have to change from the default font.
It is the only work around I have found so far, the down size is that the font in Step 7 Portal is small and hard to read.
We have made many tests with the different DPI Settings in order to work with comfort Panels and it es very important if you get a Project from another Computer (with different DPI Settings) or if you do changes in your DPI Settings in the Windows you have to do a recompile all, that the Whole Project is generated in the correct DPI Setting.
Came to this thread a few years after the original post. I'm running into the same issue with Windows 10 20H2 running TIA Portal 15.1 Update 5. With replies here pointing to DPI being the issue, I dug into it.
So I navigated to "C:\Program Files (x86)\Siemens\Automation\WinCC RT Advanced\" and brought up the properties for HmiRTm.exe. On the compatibility tab, I clicked the button "Change high DPI settings". On the resulting popup, under the second group named High DPI scaling override, check the box for "Override high DPI scaling behavior" and then selected "System" from the drop-down menu.
The 4K display is a very complex topic that affects several TIA Portal products (STEP 7, WinCC, Startdrive, etc.). You can look up the problems that can arise in connection with an HMI panel if the scaling is changed under Windows in this FAQ:
