Question Acer monitor defect fixable?

Return it ASAP.
That could be a defect that appears to be as if they were dead pixels on the panel.
If you're curious you could run a test to see if they are dead pixels.
Dan's dead pixel app
Open the app, move the slider to 5 minutes.
Click the small or medium button and move the flashing window right in the middle of the black dots.

Caution🚸: The app flashes multiple colors on the screen and can trigger an epilepsy attack. Make sure you or anyone who may be looking at the screen is aware of this before using the app.
