Uni and Bi-directional cables are discussed at:
https://www.club-3d.com/en/technology/16/uni_and_bi_directional/

Both the CAC-2068 and the CAC-1092 are bi-directional.

I don’t believe either cable should provide any improvement compared to the DisplayPort cable that comes with the LG 32GS95UV unless that cable is damaged.

DisplayPort 1.4a is slightly newer than 1.4. It requires the same cable bandwidth.
https://en.wikipedia.org/wiki/DisplayPort

Yes, the Club 3D CAC-1092 DisplayPort™ 2.1 VESA DP80 Certified Cable 8K240Hz 1.6m/5.25ft should be more than sufficient for your purpose.

Another cable that should work is the Club 3D CAC-2068 DisplayPort™ 1.4 HBR3 Cable VESA Certified M/M 2 m / 6.56ft 28AWG

Hello, I have an LG 32GS95UV monitor and I would like to know which is the best club3d cable that I should buy for dual mode 480hz, mode without dual mode 240hz, etc., I don’t see any on the web, if someone can help me I would appreciate it, greetings and thank you.

The product page says you have two connection choices:
DP 1.4 or HDMI 2.1

If you have a GPU that supports HDMI 2.1, then get a 48 Gbps HDMI 2.1 cable.

Otherwise, get a 32.4 Gbps DisplayPort 1.4 cable or a 80 Gbps DisplayPort 2.1 cable which should work just as well.

It has retimers so I guess that can be considered active.

An MtoF adapter might work. Or it might not. It may depend on what you plug into the F connector. They might not support 240W charging which could be bad. If you try it, be ready to disconnect it before it melts.

The product page does not say if this cable supports USB 2.0, USB 3,1, USB 3.2, DisplayPort, or Thunderbolt signals which kind of makes it uninformative.

[joevt]

I don’t think it’s active enough to require firmware that needs updating but who knows? I’ve never heard of such a thing for this type of cable though.

Search for VESA certified bidirectional USB-C to DisplayPort cables on the VESA website?

This is an example of the simplest Thunderbolt device that can do the job:
https://eshop.macsales.com/item/OWC/TB3ADP2DPT
It depends on if the Mac mini Thunderbolt port problem goes away when you switch from using USB-C DisplayPort Alt Mode to Thunderbolt Alt Mode.

[joevt]

It’s just a cable – no complicated chips inside to apply a firmware to.

The problem is either the Mac, cable, or display. I would guess the Mac. In that case, getting replacement cables won’t help unless maybe they are a different brand or length or construction.

To test them, you need a different Mac, cable, or display to try different combinations.

One solution might be to connect the displays to a Thunderbolt 4/5 hub instead of the Mac.

Another solution might be to use a Thunderbolt to Dual DisplayPort Adapter. Then you can use the normal DisplayPort cables that came with the displays, and it would only take one Thunderbolt port from the Mac.

8K60 is similar to 4K240 in terms of bandwidth so 4K144 should work. Maybe they said 4K120 because the CTA-861-I spec used by HDMI doesn’t have 4K144 or 4K240 modes?

[joevt]

You are connecting a CAC-1510-A to a Thunderbolt port of the Studio Ultra?

Did you verify using SwitchResX that the current resolution selected for the display has the exact same timing as one of the modes listed in the display’s EDID? Either 1280×800 or 2560×1600? Double click the current display mode in the Current Resolutions list in SwitchResX to view the timing information (pixel clock, front porch, etc.) for that display mode.

Do you see issues like those pictured at: https://insights.club-3d.com/thread/flickering-problem-with-cac-1510-a-and-apple-cinema-display-30-on-mac-mini-m1/   ?

Notes about the Synaptics VMM2320 based DisplayPort/USB-C to Dual Link DVI adapters:

Do you mean HDMI to USB-C adapter? (since you have an HDMI output and need a USB-C output to connect the USB-C input of the CAC-1510). I’m not sure if USB-C adapters like the CAC-1510-A can work with HDMI to USB-C adapters.
https://insights.club-3d.com/thread/cac-1336-operation/

HDMI to DVI adapter could work but only for DVI single link mode 1280×800. HDMI to Dual Link DVI adapters are usually just cheap passive single link only adapters. You need a dual link adapter like the CAC-1510-A to get 2560×1600 on a dual link DVI display like the Apple 30inch.

Your gaming PC needs a USB-C port that support USB-C DisplayPort Alt Mode for the CAC-1510-A.

Or you could get a DisplayPort to Dual Link DVI adapter like the CAC-1010-A.
https://www.club-3d.com/en/detail/2526/displayport_to_dual_link_dvi_d_hdcp_off_version_active_adapter_m-f_for_apple_cinema_displays/

Did you check the EDID of your Apple 30inch to verify that it doesn’t have HDCP? If it has HDCP, then the HDCP ON versions of the adapters might be better (for displaying content that uses HDCP). Old Apple 30inch displays don’t have HDCP. Later ones do.

They might take a few days to reply though.

USB-C to Dual Link DVI-D adapter should work with Mac mini M4 and any DVI display.

Cinema HD Display 23″ doesn’t require Dual Link DVI-D for max resolution. It might work with a passive HDMI to DVI adapter.

[joevt]

Maybe you need “Intel Graphics Control Panel” or the newer “Intel Graphics Command Center”.

What GPU are you using?

What refresh rates are you attempting for each display?

Do you know the pixel clock for the display modes of each display?

What color depth are you attempting for each display?

The CSV-1585 appears to be a DisplayPort 1.4 MST hub supporting HBR3 x2 with DSC for input and DSC decompression for output.

Does your GPU support DSC? With DSC support, the total pixel clock for both displays can approach 1080 MHz (assuming DSC@12bpp but DSC can compress down to 8bpp).

Without DSC support, the total pixel clock for both displays is limited to 540 MHz for 8bpc and 432 MHz for 10bpc.

Many MST hubs don’t support 10bpc decompression. In that case, you may need to select 8bpc (but HDR usually requires 10bpc).

The MHz numbers are maximums. DisplayPort MST overhead will reduce those.

An Intel Mac can use AllRez to get the DPCD info of the MST hub. There may be other methods to get DPCD info from Linux or Windows. The DPCD info will show most of the capabilities of the MST hub.
