Simulate higher screen resolution because I want to ZOOM IN later using screen capture software (like Camtasia)

Question

I'm recording tutorials for audio software and I always find myself zooming in on details when editing the screen captures. As a result, the zooming-ini parts have a bad resolution and look blurred.

The max screen resolution for my monitor is 1920x1080 and I'm using a GeForce GTX 750 TI graphic card.

Is there a way to record at a simulated higher 2K screen resolution? My goal is to achieve better quality/resolution when zoooming in 180% when using the screen capture software.

Is the only way to record at a higher resolution to buy a 2K monitor?

Help is very much appreciated.
