CentOS Linux: Stop Monitor From Going to Sleep Using, Turn Off Powersave

I have a couple of Linux servers at my house and sometimes I will be viewing something on the screen for a long time and will continue to need to look back to the monitor for reference. Anyhow my monitors kept turning off or hibernating after about 15 to 30 minutes. Initially I thought this would be something I could modify in the BIOS of each of these computers but I was incorrect. The way to stop powersave mode in Linux is using the setterm command. Use the syntax below to turn off powersave mode and stop your monitor from going to sleep.
