CalDigit TS5 Plus + MacBook Pro M5 Max: Can It Run 4 Monitors?
Yes — with an important connection requirement. DeskCheck returns PASS for a MacBook Pro 14-inch with M5 Max connected to a CalDigit TS5 Plus with four external 4K displays at 60 Hz. The fourth display requires a Thunderbolt daisy-chain rather than a fourth direct dock output.
The TS5 Plus has three direct display-capable dock paths. CalDigit's documented four-display M5 Max configuration requires one Thunderbolt monitor that supports daisy-chaining, with the fourth display connected downstream from that monitor.
Setup checked
CalDigit TS5 Plus for this setup
CalDigit TS5 Plus Thunderbolt 5 Dock
CalDigit specifically documents support for up to four external displays from the TS5 Plus when connected to an M5 Max MacBook Pro, provided the required Thunderbolt daisy-chain configuration is used.

Four monitors require a specific connection layout
Unlike the three-monitor configuration, you cannot simply connect four monitors directly to four independent video outputs on the TS5 Plus.
One of the displays must be a Thunderbolt monitor capable of daisy-chaining another display.
See the 4-monitor connection requirements →Why this setup works
Apple documents support for up to four external displays on the M5 Max MacBook Pro.
Apple's documented four-display configuration supports four displays at up to 6K 60 Hz or 4K 144 Hz each. The four-display 4K 60 Hz target checked here is below that documented host ceiling.
Apple also states that a supported hub or display daisy-chain can enable up to four displays over a single Thunderbolt port without increasing the Mac's overall four-display maximum.
CalDigit separately documents that the TS5 Plus can support up to four monitors from one Thunderbolt 5 connection on an M5 Max MacBook Pro.
How the four monitors connect
CalDigit's documented four-display TS5 Plus configuration for M5 Max uses the following connection layout:
Display 3 needs to be a Thunderbolt monitor that actually supports downstream Thunderbolt display daisy-chaining. Having a USB-C input alone does not prove that capability.
Why DeskCheck does not call this four direct outputs
The TS5 Plus physically provides two downstream Thunderbolt 5 display-capable ports and one DisplayPort 2.1 output.
That gives DeskCheck three verified direct dock display paths.
The M5 Max four-display result is still a PASS because CalDigit explicitly documents the fourth display through a Thunderbolt daisy-chain. DeskCheck keeps that separate from its direct-output monitor allocator so it does not incorrectly claim that the dock has four independent physical display outputs.
What you need
- MacBook Pro 14-inch — M5 Max
- CalDigit TS5 Plus
- Four external monitors capable of the requested 4K 60 Hz mode
- At least one Thunderbolt monitor that explicitly supports downstream Thunderbolt display daisy-chaining
- Appropriate cables or video adapters for every display connection
- The TS5 Plus connected directly to the MacBook Pro through its Thunderbolt 5 host connection
- DisplayLink software is not required for this documented four-display configuration
Do you need DisplayLink?
No.
This configuration uses the native display capabilities documented by Apple and CalDigit.
The fourth display is achieved through Thunderbolt daisy-chaining, not through DisplayLink software.
Can the TS5 Plus supply power to the MacBook Pro?
Yes. CalDigit documents up to 140W of host power delivery through the TS5 Plus Thunderbolt 5 host port.
DeskCheck treats 140W as the dock's documented host power capability. It does not claim that a particular wattage guarantees sufficient charging under every workload or operating condition.
Why DeskCheck is not showing a generic 4-monitor list here
DeskCheck's current monitor matcher verifies direct compatible dock outputs.
The TS5 Plus four-display M5 Max configuration depends on a downstream Thunderbolt daisy-chain, so a normal four-monitor recommendation list could incorrectly imply that any four compatible monitors will work.
For this setup, the third monitor's daisy-chain capability is an additional requirement that must be verified separately.
Important limitations
- This PASS applies specifically to the MacBook Pro 14-inch M5 Max, CalDigit TS5 Plus, and four external displays at 4K 60 Hz.
- The fourth display requires the documented Thunderbolt daisy-chain configuration.
- The TS5 Plus does not have four independent direct physical display outputs.
- A USB-C monitor is not automatically a daisy-chainable Thunderbolt monitor.
- Monitors, cables, and adapters still need to support the requested resolution and refresh rate.
- CalDigit notes that display bandwidth and individual monitor capabilities can affect four-display operation. Being below a stated resolution ceiling alone does not guarantee every monitor combination.
- DisplayLink is not required for the documented configuration covered here.
- PASS reflects documented pre-purchase compatibility. It does not guarantee against defective hardware, cable faults, firmware issues, or operating-system problems.
