A:Answer Thank you for your question on this HP Envy Desktop computer and its display capabilities. This computer does not support three monitors in extended mode as it lacks the connections required. You would need to add a video card that has at least three ports on it, which may also require an upgrade to the power supply. For a desktop computer that can support 3 extended-mode displays, look for one that has a dedicated graphics card, which you can find on some Envy models, along with the full selection of Victus and Omen gaming desktops.
