Custom Monitor Size - Revit

[ETHETREE]

I use Autodesk Revit all of the time at work. And if you have ever worked with Revit you are familiar with the project browser and the properties palettes (see attached). I do have two screens but I would like to add a third screen to the far left just for the properties palette. So the order (from left to right) would be first screen properties and project browser, second would be the main Revit program, and the third screen would have pdfs, excel calculators, etc. The only problem is that i need a screen that has a usable area of about 13.5" tall and 3" to 5" wide. This is a abnormal aspect ratio and i cannot find anything like it. Any help or products would be appreciated.

I mean just get a regular monitor and turn it to it's side. You are simply limited to existing aspect ratio's basically.
