Does the M4 Mac mini support 1440p @ 360Hz?

I have recently purchased the (currently new) base-model M4 Mac mini (running MacOS Sequoia) in combination with the Samsung Odyssey OLED g60sd. The latter is capable of displaying a resolution that of 2560x1440 at a 360Hz refresh rate. I have attempted finding answers to my questions online to no avail.

As of now, I am aware of the fact that the monitor is able to support the necessary bandwidth via DisplayPort 1.4 in addition to DSC (as is a given).

Regarding the M4 Mac mini, Apple's documentation lacks explicit details on whether or not the M4 chip supports DSC. Furthermore, I did not find any information on what the maximum refresh rate is, which the Mac is able to output/ supports.

The HDMI cable that is included with the monitor only supports 1440p @ 120Hz. This is why I would also appreciate any recommendations on which cable to acquire that is able to handle 1440p @ 360Hz.

Any information concerning the aforementioned inquiries is welcome!

P.S. I know this is not the best choice of monitor for the Mac, considering that I plan on gaming on it and my Xbox Series S. The reason I bought this monitor is due to an unbelievably good deal that presented itself to me.

Mac mini, macOS 15.1

I purchased this USB-C to DisplayPort 2.1 cable and when I plugged it into my monitor and my base-model M4 Mac mini (into one of the Thunderbolt 4 ports at the back of the Mac), I was shocked to be able to select a refresh rate of 360Hz.

I am unsure as to why this is the case and if the refresh rate is truly 360Hz or if that information is false. I believe it to be beneficial, if someone with the appropriate understanding and knowledge concerning this topic investigates this further. Perhaps someone already knows what's going on.

Thanks to everyone in advance! Any insight is greatly appreciated!

You're welcome.

The mini can output video on its USB-C, HDMI and Thunderbolt ports.

The resolution and refresh rate on each will vary, but that is also listed in the specs.

The Samsung monitor has DisplayPort input which can be fed by the mini's Thunderbolt port. It also has USB and HDMI, so those could be used.

Whatever connection option you choose, I'd advise you to use the best quality cable that you can. Macs tend to be finicky where cabling is concerned.

That is a good cable choice. This is why I suggested using USB-C to DisplayPort instead of an HDMI cable. The 4K 2560 x 1440 resolution of that 27" display is allowing the higher refresh rate. If you had a larger higher resolution display or a lower rated cable, then you would certainly be bumped down to 240 or even 120 Hz.

Can you do this with two monitors at once??

1 via HDMI and 1 via USB-C to DisplayPort / HDMI?

Yes!

Plus some of the later Mac mini’s can actually run two displays from their USB-C ports.

The following is copied directly from the support article that I posted.

For Mac mini with Apple M4, you can connect up to three displays in the following configurations:

Connect up to three displays, two with up to 6K resolution at 60 Hz over Thunderbolt, and one with up to 5K resolution at 60 Hz over Thunderbolt or 4K resolution at 60 Hz over HDMI.

Connect up to two displays, one with up to 5K resolution at 60 Hz over Thunderbolt, and one with up to 8K resolution at 60 Hz or 4K resolution at 240 Hz over Thunderbolt or HDMI.

The Mac mini's display support is clearly stated here: Mac mini - Technical Specifications - Apple

I do not believe the mini supports any display output above 240Hz, if it did I'm sure Apple would consider that a marketable feature and include it in the specs.
