### Slowness

If you are running on a multi-screen system, or a very high-resolution screen, you may find that Desert Paint Lab is rather slow in determining paint reactions.  That's because you have a lot of screen real-estate to scan, to look for the Pigment Lab dialog.  You can speed up the scanning process by ensuring that your Pigment Lab Dialog is as far to the upper-left of the screen as possible.

### Multiple Displays

When Desert Paint Lab asks for the resolution for a multiple-display setup, enter the combined resolution of all displays. Generally the detected default for this will be correct. For example, two 1920x1080 displays in a side-by-side configuration would be a combined resolution of 3840x1080. In a stacked configuration, they would be 1920x2160.

### Retina / High-Density Screens

High DPI screens may be displaying the game at something other than a 1:1 game-pixel to screen-pixel ratio.  These screens didn't exist, back when Desert Paint Lab was created. The current version now prompts you for your screen resolution when it starts to work around this. If you see a crash when trying to capture a reaction, it's likely because the resolution is incorrect. For example, Snoerr's MacBook Pro has a retina screen with a resolution of 2880x1800. Mono (and therefore DesertPaintLab) detects it as having a resolution of 1440x900. He enters his resolution as 2880x1800 and sets the Game pixel width in screen pixels to 2.

## Mac user FAQ

Q: How do I find my native screen resolution?

A: You can find it by opening up "About this Mac" from the Apple menu and clicking on the "Displays" tab. That should show the screen size and resolution to enter.
