Screen Size

Minimum resolution required for Open Dental is 1280 x 768. This is less than an HD monitor, which is 1920 x 1080. Open Dental should work on most monitors and laptops, but if you have a very small laptop, do make sure that the screen resolution is at least 1280 x 768.

Text Looks Too Small

Monitors have been gradually increasing in resolution. This causes the text in programs to look smaller. This is most noticeable on an HD monitor with small physical dimensions.

Suggested strategies:

  • Never purchase a 22" or smaller HD monitor. Text simply looks too small
  • Try to purchase only 27" or 28" monitors.
  • If you must purchase a smaller monitor, get one with lower resolution so that text looks bigger.
  • A laptop with 1280 x 768 will look better than a laptop with HD 1920 x 1080.
  • Set custom scaling to 130%, as described below.
  • Any resolution higher than HD will look better than HD because you can scale more than 130%. Examples:
    • 1920 x 1200
    • 2560 x 1440
    • 4096 x 2160 4K, although they are more expensive.

Custom Scaling

Windows has had support for custom scaling for a long time. In older versions of Windows, this was done by setting your font size slightly larger, like 125%. Windows 10 accomplishes this differently, by taking a screenshot of a window, and simply enlarging that image. Because lines in each font are designed to fall directly on a row of pixels, changing the scale by 5% or 10% just makes everything blurry. But at a scale of about 130%, the advantage of larger fonts probably outweighs the blurriness. You can get used to it after little while. Here's a rough comparison of the difference:


Windows does not allow custom scaling per application, so you will need to set the custom scaling for the whole computer. Some programs like internet browsers and image editors will not get blurry when scaling. Each program behaves a little bit differently. In Windows 10, go to Settings, System, Display. Look in the Scale and layout section.

Click Advanced scaling settings.

Change scaling to 130, click Apply, and follow the suggestion to Sign out of Windows, then Sign back in.

4k Monitors

4K monitors are more expensive, but they are more flexible for scaling. Because there are more pixels, scaling to 130%, for example, will not result in blurriness. Windows considers a 4K monitor to be a "high DPI" display. On a high DPI display, Windows 10 will always scale all windows to double their original size to prevent them from being absurdly small. You can turn off this automatic high DPI scaling on a per-application basis from the application Properties Compatibility window, but it's not useful in this case because it would just make the window small.
