Yes, you're right, 3 monitors out of box (display ports, assuming your monitors have those, or using compatible converters if not).Optiplex 7000 Tower and SFF versions both have 3 display port outputs for monitor from integrated GPU (which is part of CPU unless you're buying F version of it).Fourth monitor (12th gen Intel CPUs natively support up to 4 displays) can be connected via Daisy-Chain (MST functionality) or by adding (if not already included) optional HDMI/VGA/DVI?/DP dongle (motherboard has additional internal connector for it numbered as "23" on service manual).
Hi. How many monitors does the Optiplex 7000 support without any option added?
