how to connect Mac Studio M2 to Dell UltraSharp 32 8K Monitor UP3218K

It works out of box for me using two TB to DP cables in MacBook Pro M2 MAX.

Displays:

DELL UP3218K:

  Resolution: 7680 x 4320 (4320p/8K UHD 2 - 8K Ultra High Definition)

  UI Looks like: 3840 x 2160 @ 60.00Hz

  Main Display: Yes

  Mirror: Off

  Online: Yes

  Rotation: Supported

Looking at Apple's Technical Specifications, I believe that

• Both versions of the M2 Studio support 8K resolution at 60 Hz over HDMI
• Only the M2 Ultra Studio supports 8K resolution over USB-C (DP) or Thunderbolt (not sure which)

Looking at Dell's site, it appears that the UltraSharp UP3218K has two DisplayPort inputs and no HDMI input. The user manual says "To display 7680 x 4320 at 60 Hz, both DP1 and DP2 must be connected to the same graphics card. DP source’s graphics card must be DP1.4 certified and Tile display feature, capable of supporting resolution up to 7680 x 4320 at 60Hz and its driver supports DisplayID v1.3."

Whether you could run a couple of USB-C to DisplayPort cables from a Mac Studio to the Dell UP3218K and get the 8K resolution is something I don't know. You'd need to spend some time talking to Dell Support and to Apple Support to figure that one out.

But it seems like there is a mismatch here between the form in which the Dell monitor wants to see the signal and the form(s) in which the M2 Studios are prepared to present it. So before shelling out $4025 (plus tax) on that 8K monitor, you really ought to resolve the "Compatible?" question with someone who can answer more definitively.

This can work. You can run two cables to a high-end display provided the Display supports Picture-by-picture [terminology may vary]. The display will report is capabilities to the Mac over each of the two cables as 'half a screen'.

On the Mac, you run this as TWO virtual displays (representing right-side and left-side) placed right next to each other in the arrangement pane:

yours will show two Equal blue boxes, but I don't have that on hand to include here)

In the display, use Picture-by-Picture (a variant of Picture-in Picture) to place the two virtual displays into the correct position side-by-side. [terminology may vary]

"Extended Desktop" is embedded deep inside MacOS, and has been working very nicely since at least 1987, introduced on the Mac-II and Mac-IIfx.

Windows placed on the boundary (half on each display) have always scrolled "the right way".

You will most likely have to jump into the pilot seat and perform the test flight for yourself.

I'd take along an extra an 8K USB-C to DisplayPort cable in case the Dell supplied cable doesn't cut the mustard.

You would need a TB to DP adapter and connect that way but not sure about the resolution being supported.
