Can I use a Samsung monitor to work with Mac Studio?

You can use a standard 4K HDMI cable to connect the monitor to your Studio or if your HDMI port is in use a USB-C to HDMI cable or adapter. 8k cable is not needed and would be a waste of money. I have 2 Dell 34s that are the same resolution as your Samsung, one runs off the HDMI port on my Studio and the other uses an HDMI cable connected to an Apple Multi-port adapter USB-C Digital AV Multiport Adapter - Education - Apple

and both work fine.

Sadly, you are mistaken, on my Studio I am running 2 Dell 3422DW ultra-wide monitors at 3440x1440 @ 100Hz and a Samsung 55" TV at 3840 x2160 (4K) @ 60 Hz all 3 on HDMI cables with no issues whatsoever.

Yes you can use HDMI and it will work. But sadly, HDMI is limited to 1080 and does not truly support higher wide screen resolutions.

What model # is the 34" Samsung display that you are looking at...?

3440x1440 implies that it is a curved wide screen.

If it is, then it should have DisplayPort input and you should use an 8K USB-C to DisplayPort 1.4 cable.

for example: > https://www.amazon.com/dp/B0C7BYT6C9/ref=sspa_dk_detail_4?

We've seen cases were two cables are necessary to access all of the Displays features.

A premium 8K USB-C to DisplayPort 1.4 cable for the Video connection.

Plus a USB-C cable for sound output and the downstream USB ports.

At this point you should chat with Samsung support to see with have to say and promise.

this one will not break the bank:

Monoprice 8K Certified Ultra High Speed HDMI Cable - HDMI 2.1, 8K@60Hz, 48Gbps, CL2 In-Wall Rated, 30AWG, 6ft, Black - Product # 42674 -$7.19

NB>> Higher than 4K @ 60 is only available on 2023 models (with at least M2 processors)

Older models with M1 processors reach 4K @ 60 ONLY

Thanks for confirming what you have, but I’m betting that you had to spring for more expensive Premium Certified Category 3 or 4 HDMI cables to get those resolutions.
