I am looking to purchase a M4 Mac Mini and use the Dell UltraSharp U2725QE, just one monitor. Is it possible to use the 120 Hz refresh rate in this configuration? I can not find any information about this on Dell, Apple, or Amazon sites, and ChatGTP is not at all sure. Thank you for your help.
Mac mini (M4, 2024)
Mac mini M3 was released in 2024 and has
Thunderbolt 5 ports (backward-compatible with ThunderBolt-4) and an HDMI 2.1 port
You could connect it and expect 120 Hz operation using:
• Thunderbolt-5 (on the back) of the Mini, using a Thunderbolt 4 or better cable limited to 0.5 meters maximum length -- this would allow you to use the additional ports such as Ethernet port and USB-C on the display at the same time)
• HDMI port using ULTRA certified HDMI cable of modest length. (but additional cables would be needed to support any additional ports on the display)
NB>> For this use, Thunderbolt 5 cables are not required, and are not fundamentally different than ThunderBolt-4 cables. Thunderbolt-5 runs at the same nominal speed, but is backward-compatible.
When talking to other ThunderBolt-5 devices, the interface changes to a modulated signal with multiple patterns per signaling interval.
the dell U2725QE appears to be a 3840 by 2160 "4K" display with up to 120 Hx refresh rate.
it is capable of 10 bits.color HDR=ON (which it appears to implement with 8 bits plus FRC)
interfaces include
DisplayPort 1.4 with Display Stream Compression (DSC)
HDMI 2.1
ThunderBolt 4 with up to 140 Watts power delivery available
USB-C (data only)
The M4 Mac Mini supports up to 240Hz at 4K. Greater resolutions will have a lower refresh

Is it possible to use the M4 Mac Mini with single Dell U2725QE at 120 Hz refresh rate?
