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.
If your monitor resolution is a little higher than the minimum above, you can use the Zoom feature to make Open Dental easier to see.
