@joeydelarago --  if the ACER computer is running Windows 10, and one of the HP or DELL monitors are connected:

1. hold-down the Windows key (bottom-left of your keyboard)
2. tap the "P" key
3. release the Windows key

Do you see options to "duplicate" or "extend" the Windows desktop onto the HP (or DELL)  monitor?
