Monitor for Mac Mini M2

Just to add, I am a fairly serious amateur photographer and the colors and depth of the LG display are perfectly fine my usage.

In addition, any display you plan to get, toss the cables that come with the display and purchase certified HDMI or DisplayPort cables. Manufacturers will supply the cheapest cables they can get away with and they can sometimes be problematic.

The others are spot-on in saying that most aftermarket displays will work with the Mac mini's.

I have dual Samsung displays connected to one Mac mini and dual LG displays connected to the other.

I never had a monitor not work, currently my mac mini is connected to a very very old 17" samsung monitor with 1280_1024 res using a thunderbolt to dvi adaptor and an asus 27" 1080p monitor using a hdmi to dvi adaptor

so you can use a monitor with hdmi or a monitor with thunderbolt usb-c connector or use adaptors

A gaming display such as the one you listed is way overkill for your needs.

No, you do not need a Thunderbolt4 display as the MacMini already has an HDMI port for video.

As far as resolution, 4K displays are nice (I have one myself) but even a 2K display (2560x1440) would well suit your needs. At the size display you are considering, I personally would not consider HD display (1920x1080).

I have had good luck with the basic LG displays. I currently own an LG 27UP600 which is a a basic 4K UHD HDR400 display. It has a minimally adjustable stand. There are two other versions, 650 and 850, which simply add more bells and whistles but all have the same display functionality.
