People who are running CTPlus on high resolution displays (e.g. 4K/2160p) may notice that certain elements of the software are displayed in unexpected ways, such as windows or controls being smaller than expected. This is due to interactions with scaling within the Windows OS, which adjusts the size of text, images, etc. to make them more visible on high-res displays.
This guide will help show how to override these settings for the CTPlus application, allowing correct behaviour of displayed elements.
- Open a file explorer window and navigate to the CTPlus installation folder (default: "C:\Program Files (x86)\Tecom\CTPlus").
- Right-click on the ‘pcgui’ application, then select ‘Properties’.
- Click on the ‘Compatibility’ tab, and if applicable also click the button ‘Change settings for all users’.
- Click on the ‘Change high DPI settings’ button.
- Click on the checkbox under ‘Program DPI’. The dropdown for what DPI setting to use should already be set to ‘I signed in to Windows’.
- Click on the checkbox under ‘High DPI scaling override’, and select ‘System’ from the dropdown.
- Click the ‘OK’ button to save changes and close the windows.
When you open CTPlus, all scaling issues should now be resolved. You may notice that text and images look a bit fuzzy, however they should still be readable and easy to interact with.
