Choose your monitor's make and model
The first step is to tell SaX2 what kind of monitor you have so it can determine capabilities. Click the Monitors option on the main screen and, on the resulting "Currently configured monitors" screen, click the Properties button. On the Monitor-Model tab, find your monitor and model and click OK. Click the Finish button on the "Currently configured monitors" screen. If your monitor isn't shown, pick the closest one. My monitor, a Dell 2405FPW, is not on the list of available monitors, but a 2000FP is pretty close.
