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.
Note: If you make changes in Microsoft Display Settings, close the Zoom window and reopen to reflect new settings.
- Resolution: Current monitor resolution based on Microsoft Display Settings.
- Working Area: Current working area, or desktop area excluding the taskbar.
- Microsoft Scale: Current resolution scale.
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:
- Total Scale: Combined scale percentage from Microsoft and Additional Scale.
- Design Specs: Maximum size of window that our engineers will design.
- Maximum Size: Maximum size of resolution after additional scale is applied.
- Fit: Displays YES or NO indicating if scale will fit working area. Applies to normal window size, not added Patient Dashboard or docked Tasks Area.
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".
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.
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:
- Resizing by dragging corners jumps as the painting struggles to keep up with the mouse. It looks jittery.
- At the end of a resize, it can get "stuck" on your mouse for a moment and end up a different size than you intended. Just slow down a little. Pause your mouse for a moment after you release the button. This will give the software time to catch up.
- If dragging the title away from maximize, the entire window will flicker away from the mouse to the "restore" size and position before jumping back to the mouse. Just hold the mouse button down and wait for it to catch up.
- If you restore a minimized window from the task bar, it can be slightly bigger than when you minimized it. This is usually only noticeable with repeated minimize and restore.
- A maximized window can still be resized by grabbing the edges. This can actually be an advantage in some situations. You can maximize and then drag an edge so that it only fills half the screen. The annoyance is that some users are used to slamming the mouse over to the left to use the Module buttons. You will need to retrain yourself to aim for the middle of the desired module button.
- When you drag a window to a high dpi monitor, it can hang for a moment while it redraws the new size. Just keep the mouse down and move slowly while it catches up.
- Snap to left or right by dragging does work, but does not include the visual hint rectangle. If you use this a lot, WindowKey-ArrowLorR might be a little faster for you.
- Snap to one of the four corners does not work.
- If Open Dental is spanning two monitors, and you click Maximize, it will maximize to the monitor with the greatest percentage, as expected. But it will also leave a narrow 8px vertical ribbon on the other monitor. Avoid this by dragging to a single monitor before clicking Maximize.
- To resize a window, you will need to grab the actual border. This is consistent with older versions of Windows, but is different than the current Windows behavior where there are no borders and you must grab outside the border to resize.
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.
