As long as you have the connection ports free on the graphics card, yes. You can hook up as many monitors as your computer/graphics card has ports for. I currently run dual (two) monitors on my gaming PC at home, and I have occasionally run three (two monitors plus a TV).
Can you run 2 monitors on one graphics card?
A single video card that supports a dual-monitor setup can handle running two screens at the same time: it is not necessary to have two video cards to run two monitors on one computer. Video cards that have two monitor connection ports typically support dual-monitor setups.
Should second monitor be plugged into graphics card?
Plug your monitor into the GPU so that you get the best visual performance and frames per second. If you plug your monitor into a motherboard then it will utilize the integrated graphics card, if your CPU has one, instead of the dedicated GPU, which would result in horrible visual performance and frames per second.
How many monitors can my graphics card support?
The best way to find out whether your graphics card supports multiple monitors is to find the name of your card (Control Panel > Device Manager > Display Adapters) and Google it with the monitor setup you’re looking to run (e.g. “Nvidia GTX 1660 four monitors”).
