In the Main Menu, click Tools, Zoom.
Zoom allows users to visually scale Open Dental, by increasing the overall display of the program. Settings are per workstation and will retain the settings after Open Dental is closed.
Settings: Opens the Microsoft Display Settings.
Additional Scale: Input a number here to add to current scale above (i.e. 10).
Reset: Resets to Microsoft Monitor Settings, making additional scale 0 (zero).
Fit: Automatically calculates a scale that will make Open Dental fit to your working area.
Additional Scale Settings:
Click OK to save. Click Cancel to exit without saving changes.
If your fonts all look too big and cut off, then it's a Windows scaling issue. Go to Windows Settings, Display, "Advanced scaling settings", which is found about halfway down in blue. Turn off the option for "Let Windows try to fix apps so they're not blurry". It may be required to restart the workstation for setting to take affect.
Details about that setting for anyone who's curious: Windows is trying to fix a specific scenario that only happens when your primary display is not 100%. This feature was introduced in April 2018, and is on by default in more recent versions. Among other things, it takes control of the fonts rather than letting the applications control them. This can help with some older apps that are not dpi aware. But Open Dental is already dpi aware and is already scaling the fonts. When Windows additionally scales the fonts, they look too big. We have not yet been able to find a setting to turn off this "feature" for one app, and such an option may not exist.
Windows has another completely different feature that allows you to turn off the DPI awareness for one application at a time. This might be useful if Open Dental has a certain kind of layout bug. This could be used to temporarily fix the issue until we can address it. Turning this on results in the entire interface of Open Dental becoming slightly blurry at resolutions other than 100%. It's generally not recommended. On the Open Dental executable or shortcut, right-click and select Properties, then Compatibility. Click Change high DPI Settings. Check Override high DPI scaling behavior. Change the Scaling performed by to System.
The above steps might not work for certain users. An example would be if you are using remote apps from a Windows 2019 server. For those situations, we offer a simple override that turns off dpi awareness for Open Dental. This is done one computer (or app server) at a time. Go to C:\Program Files (x86)\Open Dental\. Manually add an empty text file called "NoDpi.txt". If your computer does not show file extensions, then it will just look like "NoDpi". Now, when you start Open Dental, it will not be dpi aware.
There is an intermittent issue if using Remote Apps on Server 2019. A maximized window can get shifted down and to the right by 8 pixels, but the mouse clicks still register at the old locations, resulting in frequent erroneous clicks. There is an override that turns off our custom borders and uses Microsoft borders instead. Go to C:\Program Files (x86)\Open Dental\. Manually add an empty text file called "NoCustomBorders.txt". But if you use this option, you must also set Open Dental to be dpi unaware. The typical way of doing this is to also add "NoDpi.txt" to the application folder. Neither of these will interfere with our Zoom feature.
It was technically difficult to implement the Zoom feature. We had to build our own layout system. This results in some artifacts when resizing any window:
We are aware of all these issues. We are working on ways to improve performance and eliminate these artifacts, but it will not happen soon. The artifacts are tolerable. We feel that the advantages of having zoom far outweigh the resizing annoyances.
