Good day!

The best way to get rid of your dizziness is to be aware in the first place.

-You should have to take a break every 20 minutes.
-Try to blink your eyes more. It allows you to rest your eyes.
-Ensure you have proper lighting in your worsktation. Adjust the screen brightness and contrast of your device.
-Clean your screen that will remove electrostatic particles emitted from the computer screen. Those particles can push dust toward your eyes, irritation and strain.

But I recommend you first to consult on your doctor. Make a check up appointment.
They could advice you some medication for your eyes. For the mean time, don't worry about what monitor can be used. Okay Happy
