Transparency

Check style

By default, GIMP indicates transparency using a checkerboard pattern with mid-tone checks, but you can change this if you want, either to a different type of checkerboard, or to solid black, white, or gray.

If you choose Custom checks, two color selection buttons show up that allow you to set your own preferred colors for the checkerboard.

Check size

Here you can alter the size of the squares in the checkerboard pattern used to indicate transparency.

Zoom Quality

Zoom Quality

When zooming out on large images feels sluggish, you can change this setting from High quality to Low. This can improve the speed of displaying the zoomed-out image, at the cost of lowering the quality of the display.

Monitor Resolution

Monitor Resolution is the ratio of pixels, horizontally and vertically, to inches. You have three ways to proceed here:

• Detect automatically: Get the resolution from the windowing system (easiest, probably inaccurate)

• Enter Manually

• Push the Calibrate… button to get the Calibrate Dialog

Some monitors can be impressively off. You will need a soft ruler.
