Will Mac mini M4 support 3 display connected at once?

M4 MacMini has HDMI. You do not need to get adapter for that - however, please make sure the selection of HDMI cable (premium quality and not-too-long preferable).

Yes, "3 monitors" is supported: please refer to Apple's website:

Only the M2 Pro model supports 3 displays.

The latest M4 Mac mini supports 3 displays.

However as Sam points out, these new Mac mini's are picky do not do well using long cheap HDMI cables.

You may get away with 1080p TV's on somewhat longer HDMI cables, but anything above 1080p will require short High Speed Certified HDMI cables. HDMI Boosters maybe an option for long runs to 1080p TVs, but I personally have not tested any with the latest Mac Mini's.

The only way to full guaranty success, is to buy an M4 Mac mini and test it in your setting.

Then if it doesn't work out, return it within the 14 day no questions asked window.

can we have 3 display connect in mac mini m4 chip with these areas:

The M4 and M4 Pro Mac minis have three USB-C (DIsplayPort, Thunderbolt) ports, and a HDMI port, and both support up to three displays, which can potentially all be USB-C or Thunderbolt ones.

If you examine display specifications closely, you will see that Mac minis with M4 Pro chips have better ones. I could be mistaken, but the resolution limitations on the last display on a Mac mini which has just a plain M4 chip might translate into fewer Retina scaling options for a third 4K display.

that is the BIGGEST question that I need to answer I tried to do this on the M2 chip of the mac mini and we're not getting nothing with it but I just think the mac mini m2 chip won't recognize 3 display ports

Mac minis with plain M2 chips have two USB-C (DisplayPort, Thunderbolt) ports and a HDMI port and support a maximum of two displays. Both can be USB-C or Thunderbolt displays, but in that case you must leave the Mac mini's HDMI port unused. You cannot cheat and use it, too, to drive a total of three displays.

Mac minis with M2 Pro chips have four USB-C (DisplayPort, Thunderbolt) ports and a HDMI port and support a maximum of three displays. These Mac minis cannot drive three USB-C or Thunderbolt displays. If you want to attach three displays, you must attach two via USB-C or Thunderbolt, and one via HDMI.

Please carefully read what Apple states in the Tech Specs for the M4MM you are considering. You can also simply call AppleCare and ask. The short answer is yes but YOU need to do your due diligence so you completing understand!!!!!
