Why won't my monitors work when I turn on my printer?

Episode 1105 (1:19:05)

Fred from Redding, PA
APC BE550G Back-UPS ES 8 Outlet 550VA 120V

Fred has a monitor that suddenly went out. So he replaced it with a TV and now it's gone out as well. Leo says that the original monitor may not be bad, it could be the cable. It could be a bad cable or the refresh rate settings in his computer may be incorrect. But since it happened when he turned on his printer, his power connections could be to blame and putting in an AV power supply could be helpful. They have surge suppression that will filter the power and keep it consistent. APC and Triplite are good companies that sell them. They're a bit pricey, but worth the peace of mind from the protection they provide.
