The stylus is not mandatory. If a similar price will fetch a Radiology-type monitor with enhanced grayscale discrimination, I could try that too. Any specific recommendations?
I‘m a big fan of Eizo monitors, pick up any of their premium models.
The Radiforce series is made for radiology and is very expensive.
They do have some Flexscan models in the 24–27 inch range for less than 1.000 dollars
