Answers :

According to several sites this monitor needs a 12-volt 4-amp adapter. Virtually every laptop that uses a coaxial power plug has the center pin positive and the outside shell ground. A Google search for "ct1810 replacement adapter" turned up several sources. Here's an eBay auction currently running for one vendor. If you're outside the US you should be able to find a suitable replacement on the Internet or perhaps locally.
