## 4.5. Monitor setup

Setting up a monitor consists of entering the specifications of your monitor and a description of the model and manufacturer.

You are first asked for the horizontal sync rate. It is VERY important to enter the correct value(s) from the manual. If one of the ranges given matches the rate of your monitor, then pick it, otherwise pick `custom` and enter the values from your manual.

Next is the vertical refresh rate. Again, it is VERY important that this parameter be specified correctly. Enter it in a manner similar to the horizontal sync rate.

If either rate is mis-specified, it can result in damage to your monitor.

Finally, you are asked for an "identifier", your monitor manufacturer, and model. You can just press enter to get through these quickly.
