MacBook Pro M5 Max + CalDigit TS5: Can It Run Four 4K Monitors?
Yes. Apple and CalDigit both document a four-display path for the M5 Max MacBook Pro paired with the CalDigit TS5. Four external 4K displays at 60 Hz fall within the documented display limits.
Setup checked
What you need
- MacBook Pro 14-inch — M5 Max
- CalDigit TS5
- Four external 4K monitors
- Display connections, cables, or adapters that support 4K at 60 Hz
- The TS5 connected directly to the MacBook Pro through its upstream Thunderbolt connection
- No DisplayLink software is required for this documented four-display configuration

CalDigit TS5
The Thunderbolt 5 dock used in this documented four-4K-display setup.
View CalDigit TS5 →Why this setup works
Apple documents support for up to four external displays on the M5 Max MacBook Pro.
Apple lists a four-display configuration at resolutions up to 6K at 60 Hz or 4K at 144 Hz. Four 4K monitors at 60 Hz are therefore below that documented ceiling.
Apple also specifically states that the M5 Max can support up to four external displays over a single Thunderbolt port.
CalDigit separately states that M5 Max computers can support up to four external displays from a single TS5 dock connection.
Do you need DisplayLink?
No.
This is a native Thunderbolt 5 display configuration. DisplayLink Manager is not required simply to achieve the four-display goal documented for the M5 Max and TS5.
Can the TS5 charge the M5 Max MacBook Pro?
Yes. CalDigit specifies up to 140W of host power delivery through the TS5's Thunderbolt 5 / USB4 host connection.
This allows the TS5 to provide laptop power while carrying the dock connection for displays and other peripherals.
DeskCheck is showing the dock's documented host power capability here. This guide does not claim that 140W is sufficient for every possible MacBook Pro workload.
Four monitors still require the right connections
A supported four-display count does not mean every monitor, adapter, or cable combination will automatically work.
Use display hardware that supports the required resolution and refresh rate, and follow CalDigit's documented TS5 display-connection guidance.
Important limitations
- This result applies specifically to four external displays at 4K 60 Hz.
- The four-display result applies to the M5 Max configuration covered by this guide and should not be assumed for other MacBook Pro processors.
- Higher refresh rates and other display combinations are not covered by this specific DeskCheck result.
- Monitors, cables, adapters, and display connections still need to support the requested resolution and refresh rate.
- The TS5 should be connected directly to the MacBook Pro through its upstream Thunderbolt connection.
- DisplayLink is not required for this documented four-display configuration.
- PASS reflects documented compatibility. It does not guarantee against defective hardware, cable faults, firmware issues, or operating-system problems.
