Applies to: Twelve exact model/port/requested-mode documentary cases. macOS Sequoia15.7 and lid-open state are explicit case assumptions, not installed/tested observations. No host×dock×monitor cross-product, negotiated HBR/DSC tuple or combined-system guarantee.
- video
- The chosen case's named Mac host port → documented upstream cable/transport → selected exact dock output(s) → named monitor input(s). A wrong-role socket is shown as a rejected proposal, not a working path.
- data
- Host ↔ dock USB controller ↔ separately identified peripheral. A display appearing does not establish USB peripheral data or an ordinary USB-C socket's video role.
- power
- Use each named dock's documented supply or PD-input arrangement; monitor power is independent where specified. Host charging needs a separate budget, as shown in the two worked power examples. No power is inferred from a video arrow.
What the path requires
- Match the complete host model/GPU, OS15.7, open lid, dock output and exact monitor/input stated in the chosen case. No other external displays are attached in the case.
- Requested resolution/refresh is explicit; HDR/VRR are not requested and chroma/color depth are not normalized. Read exact source mode/DSC footnotes without inventing a bandwidth table.
- Use documented upstream and display cables plus each product's stated supply. Video, USB peripheral data and power remain separate arrows.
- Exact firmware, current cable condition and actual offered modes must still be observed. No source-defined count or endpoint role is a hardware test or automatic approval.
When the monitor model is still unknown
Outside the twelve exact cases: a USB-C monitor with only a charging claim remains unidentified. Record its exact model, upstream video input, cable and requested mode; compatible host/dock families do not fill in those facts. This useful missing-information exercise is not a counted exact-model scenario.
MacBook Pro 14-inch M4 Pro/M4 Max (2024) Technical Specifications · CalDigit TS5Charging without an identified video input
Outside the twelve exact cases: if an unidentified display charges but shows no picture through a dock, trace a documented dock video output to its actual video input. A USB-C shell or charge icon does not identify the display transport. Retain the unresolved monitor model and converter direction instead of awarding a connection result.

M4 Pro / TS5 Plus / two Pro Display XDR6K60
Documented outcome: Documented component count and input roles; full6K60 path remains conditional
- MacBook Pro (14-inch, 2024), M4 Pro, 12-core CPU / 16-core GPU; case OS macOS Sequoia15.7; Thunderbolt5 / USB-C host port → CalDigit TS5 Plus designated upstream. 2 × Apple Pro Display XDR (2019) (Thunderbolt3 upstream host input), requested 6016×3384 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Mac Thunderbolt5 → supplied TS5Plus upstream cable → Computer port; two spare Thunderbolt outputs → each XDR Thunderbolt upstream input.
- The named M1–M4 Pro/Max dock cohort permits two displays. CalDigit's6K footnote requires DSC; no actual host-to-display compression/link state is asserted.
- Read the offered modes and complete source footnotes. If6K60 is not offered, preserve the actual tuple and unresolved link/DSC/cable facts instead of manufacturing a matching normalized row.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M4 Max / TS5 Plus / three Pro Display XDR6K60
Documented outcome: Documented single-dock Mac count conflict
- MacBook Pro (14-inch, 2024), M4 Max, 14-core CPU / 32-core GPU; case OS macOS Sequoia15.7; Thunderbolt5 / USB-C host port → CalDigit TS5 Plus designated upstream. 3 × Apple Pro Display XDR (2019) (Thunderbolt3 upstream host input), requested 6016×3384 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → TS5Plus → three XDR units, using both spare Thunderbolt outputs plus the dock DisplayPort as alleged third independent path.
- The selected Mac cohort has a two-display single-dock ceiling. Whole-host capacity including other host outputs does not grant three dock streams. The proposed DP-to-Thunderbolt third-display connection is also not established by matching count.
- Stop at the documented dock count; retain three exact requested XDR modes as the rejected goal. A separately documented topology and any required signal conversion need their own evidence.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M4 Pro / TS5 Plus USB data socket / Pro Display XDR6K60
Documented outcome: Documented dock-output role conflict
- MacBook Pro (14-inch, 2024), M4 Pro, 12-core CPU / 16-core GPU; case OS macOS Sequoia15.7; Thunderbolt5 / USB-C host port → CalDigit TS5 Plus designated upstream. 1 × Apple Pro Display XDR (2019) (Thunderbolt3 upstream host input), requested 6016×3384 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → TS5Plus Computer upstream; an ordinary TS5Plus USB-C data socket → XDR Thunderbolt upstream, requesting6016×3384 at60Hz.
- CalDigit distinguishes ordinary USB data ports from its spare Thunderbolt/DisplayPort video outputs. The ordinary USB-C data socket is not the stated display path.
- Correct the selected output role before investigating the conditional6K mode. USB charging or peripheral data does not establish an XDR picture; no proposed connection was tried.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M2 Pro / TS5 / two Studio Display2022 units at5120×2880/60
Documented outcome: Documented two-display cohort and named monitor footnote; actual5K60 output unobserved
- MacBook Pro (14-inch, 2023), M2 Pro, 10-core CPU / 16-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → CalDigit TS5 designated upstream. 2 × Apple Studio Display (2022) (Thunderbolt3 upstream host input), requested 5120×2880 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Mac Thunderbolt4 → supplied TS5 upstream cable → Computer port; two spare Thunderbolt outputs → each Studio Display Thunderbolt upstream, using documented Thunderbolt display cables.
- The two-display Mac cohort and Apple Studio Display dual5K footnote apply. Three spare dock sockets do not create additional Mac streams.
- Select independent extension only within the current OS/source conditions and read each offered resolution/refresh. Do not infer HBR/DSC or color-depth values from the5K label.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M2 Max / TS5 / three Studio Display2022 units at5120×2880/60
Documented outcome: Documented single-dock Mac count conflict
- MacBook Pro (14-inch, 2023), M2 Max, 12-core CPU / 30-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → CalDigit TS5 designated upstream. 3 × Apple Studio Display (2022) (Thunderbolt3 upstream host input), requested 5120×2880 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → TS5 Computer upstream → all three spare Thunderbolt outputs → three Studio Display upstream inputs.
- The named M1–M4 Max cohort supports two displays through this dock, despite three physical output sockets. The exact requested third5120×2880/60 mode remains a rejected goal.
- Use the documented two-stream count and investigate any additional display on a separately sourced host route. Do not turn the larger whole-host Max budget into a TS5 triple-display guarantee.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M4 Max / TS5 / Studio Display downstream USB-C chosen as input
Documented outcome: Documented monitor-input role conflict
- MacBook Pro (14-inch, 2024), M4 Max, 14-core CPU / 32-core GPU; case OS macOS Sequoia15.7; Thunderbolt5 / USB-C host port → CalDigit TS5 designated upstream. 1 × Apple Studio Display (2022) (one of the three downstream USB-C peripheral ports; wrong input role), requested 5120×2880 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → TS5 Computer upstream → spare Thunderbolt output → a Studio Display downstream USB-C peripheral socket, requesting5120×2880 at60Hz.
- Apple identifies one Thunderbolt3 upstream host port and three downstream USB-C peripheral ports on this exact2022 monitor. A downstream peripheral socket is not the documented host/video input.
- Identify the monitor's single upstream Thunderbolt port and supported cable before considering any mode. Merely moving the cable does not verify a whole5K60 system.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M1 Pro / TS3 Plus / two U2720Q units at3840×2160/60
Documented outcome: Documented dual4K60 component conditions; complete operation unobserved
- MacBook Pro (14-inch, 2021), M1 Pro, 8-core CPU / 14-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → CalDigit TS3 Plus designated upstream. 2 × Dell UltraSharp U2720Q (DisplayPort input), requested 3840×2160 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Mac Thunderbolt4 → included40Gb/s TS3Plus cable → host Thunderbolt port. Dock DisplayPort → first U2720Q DisplayPort input; spare Thunderbolt → StarTech CDP2DP2MBW2m USB-C/DisplayPort cable → second U2720Q DisplayPort input.
- TS3Plus explicitly lists M1Pro dual-display support and dual4K60. Dell's exact input/preset and the named second-display cable are separate component evidence.
- Check the actual macOS offered modes and documented cable/input settings. No transfer of this complete path to an unidentified replacement cable, monitor or adapter is implied.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M1 Max / TS3 Plus / two Studio Display2022 units at5120×2880/60
Documented outcome: Documented requested simultaneous-mode conflict
- MacBook Pro (14-inch, 2021), M1 Max, 10-core CPU / 24-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → CalDigit TS3 Plus designated upstream. 2 × Apple Studio Display (2022) (Thunderbolt3 upstream host input), requested 5120×2880 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → TS3Plus → two Studio Display upstream inputs, with one alleged native stream from each dock display path.
- TS3Plus documents dual4K60 or single5K60, not two5K60. Its one spare Thunderbolt socket and a DisplayPort socket are not two native Thunderbolt monitor inputs.
- Stop at the requested simultaneous-mode conflict; identify a separately documented two-Studio path rather than assuming a matching USB-C shell or passive DP conversion supplies it.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M1 Pro / TS3 Plus passive DP-to-HDMI / XG17AHPE1080p60
Documented outcome: Documented passive-converter class conflict
- MacBook Pro (14-inch, 2021), M1 Pro, 8-core CPU / 14-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → CalDigit TS3 Plus designated upstream. 1 × ASUS ROG Strix XG17AHPE (Micro-HDMI input, manual item5), requested 1920×1080 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → TS3Plus → DisplayPort output → passive DP-to-HDMI adapter class → HDMI-to-Micro-HDMI cable → XG17AHPE input item5, requesting1920×1080 at60Hz.
- CalDigit expressly requires active DP-to-HDMI conversion for this output. This class-level exclusion settles the proposal before a specific passive adapter SKU or bandwidth tuple is invented.
- Identify an exact active converter and complete Micro-HDMI cable/mode evidence before proposing a replacement. Keep the ASUS bundled supply separate; no substitute is approved by this contrary case.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M2 Pro / DKT31CDHPD3 / U2720Q3840×2160/60
Documented outcome: Documented role/count path; exact4K60 link conditions remain unresolved
- MacBook Pro (14-inch, 2023), M2 Pro, 10-core CPU / 16-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → StarTech DKT31CDHPD3 designated upstream. 1 × Dell UltraSharp U2720Q (DisplayPort input), requested 3840×2160 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Mac USB-C native DisplayPort path → DKT31 attached host cable → dock DisplayPort output → documented DisplayPort cable → U2720Q DisplayPort input.
- The dock's one-display role and endpoint input are documented. The requested3840×2160/60 rate still depends on the complete host/link/input conditions and cable; an unnormalized HBR/DSC row is not assumed.
- Record the actual offered tuple and exact cable; retain unresolved link/mode evidence rather than calling this a tested4K60 pairing. Monitor AC and optional dock PD input remain separate.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M1 Max / DKT31 / U2720Q4K60 plus XG17AHPE1080p60
Documented outcome: Documented one-display resource conflict
- MacBook Pro (14-inch, 2021), M1 Max, 10-core CPU / 24-core GPU; case OS macOS Sequoia15.7; Thunderbolt4 / USB-C host port → StarTech DKT31CDHPD3 designated upstream. 1 × Dell UltraSharp U2720Q (DisplayPort input), requested 3840×2160 at60Hz; 1 × ASUS ROG Strix XG17AHPE (Micro-HDMI input, manual item5), requested 1920×1080 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → DKT31 attached upstream; dock DisplayPort → U2720Q DisplayPort3840×2160/60, and dock HDMI → HDMI/Micro-HDMI cable → XG17AHPE item5 at1920×1080/60.
- DKT31 supports one display. The HDMI and DisplayPort sockets are alternatives, so two independent desktops are outside this exact dock count even though the host has a larger budget.
- Use one display output from this dock and investigate any second host route separately. No exact cable conversion, charging sufficiency or simultaneous mode is approved.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
M4 Pro / DKT31 data USB-C / XG17AHPE charging-only socket
Documented outcome: Documented dock-output and monitor-input role conflict
- MacBook Pro (14-inch, 2024), M4 Pro, 12-core CPU / 16-core GPU; case OS macOS Sequoia15.7; Thunderbolt5 / USB-C host port → StarTech DKT31CDHPD3 designated upstream. 1 × ASUS ROG Strix XG17AHPE (USB-C battery-charging port, manual item7; wrong video input), requested 1920×1080 at60Hz.
- Lid open with built-in display active; no other external displays. Target is the stated resolution/refresh for independent extended desktops; HDR and VRR are not requested. No chroma, color-depth, HBR, lane-count or DSC tuple is normalized or inferred.
- OS version and open-lid state are explicit documentary case assumptions to verify on the actual Mac, not observations from this run. Exact dock/monitor firmware and current cable condition remain unobserved.
- Proposal: Mac → DKT31 attached upstream; dock USB-C Data/Charge port (QSG item2) → XG17AHPE USB-C battery-charging port (manual item7), requesting1920×1080 at60Hz.
- StarTech assigns that dock socket peripheral data/charging, while ASUS assigns item7 battery charging. ASUS item6 is the USB-C DP Alt Mode video input and item5 is Micro-HDMI. This proposal contains no documented video arrow.
- Do not trial-connect to infer picture from charging. Identify the appropriate dock HDMI/DP output and monitor video input, required cable/converter and independent bundled ASUS supply; that corrected path needs its own evidence.
- Use the dock's specified supply and upstream cable. Power each display independently as its manual directs; USB peripheral data and host charging are separate tasks. Do not treat a count or role finding as an exact simultaneous-mode or hardware guarantee.
Your next useful observation
For the selected case, identify the first unresolved or conflicting stage.
Keep these limits
- SC14-10 retains an exact named target with unresolved complete4K60 link/input conditions. SC14-01 retains the source's6K DSC prerequisite without claiming negotiation.
- OS15.7 is a historical documentary case parameter within the cited Sequoia family context, not a requirement to install that release or a claim of current security support.
- All12 cases specify exact monitors; the separate missing-model observations below are not counted toward the twelve-case floor.
- No hardware, firmware, signal, USB-data, charging, software permission or OS installation test was performed.
