Analyze any display. Input a few simple details and figure out the aspect ratio, DPI, and other details of a particular display. Great for deciding which laptop or external monitor to purchase, and if it would be considered HiDPI.

Lots of handy features:

• Find out if a display is a good choice based on its size and resolution
• Get advice about different densities
• Learn the logical resolution
• Differentiate between laptops and desktop displays
• Stupid simple: all in a cute li'l window

Based my expertise and experience shipping HiDPI hardware and software at System76 and elementary.

Tells you if a display’s density is:

• Very Low DPI,
• Fairly Low DPI,
• Ideal for LoDPI,
• Potentially Problematic,
• Ideal for HiDPI,
• Fairly High for HiDPI, or
• Too High DPI
