ASUS ProArt PA279CV + Dell Pro Max 16 + WD22TB4: Can It Run Dual 4K?
Yes. DeskCheck returns PASS for a Dell Pro Max 16 MC16250 connected to a Dell WD22TB4 with two ASUS ProArt PA279CV monitors at 4K 60 Hz, using verified DisplayPort or HDMI monitor inputs.
ASUS documents the PA279CV at up to 3840×2160 and 60 Hz. Its USB-C input has an important bandwidth caveat: when USB transmission is configured for USB 3.2, ASUS limits the USB-C video path to 4K30.

Recommended connection layout
For this dual-4K60 setup, use the WD22TB4's verified display outputs together with the PA279CV's DisplayPort or HDMI inputs.
The PA279CV includes DisplayPort 1.2 and HDMI 2.0 inputs, both of which are appropriate connection types for the verified 4K60 target in DeskCheck.
Why DeskCheck avoids the PA279CV USB-C path here
The monitor does have USB-C with DisplayPort Alt Mode and 65W power delivery.
However, ASUS explicitly states that video and USB data share bandwidth. When USB transmission is set to USB 3.2, maximum USB-C video resolution is limited to 4K at 30 Hz.
Because this page is specifically about two monitors at 4K 60 Hz, DeskCheck uses the cleaner documented DisplayPort/HDMI paths instead of assuming a USB-C mode that is not verified for the same conditions.
Why this setup passes
DeskCheck already verifies the Dell Pro Max 16 MC16250 and WD22TB4 combination for dual external 4K displays.
ASUS separately documents the PA279CV as a 3840×2160 monitor with a maximum refresh rate of 60 Hz, plus DisplayPort 1.2 and HDMI 2.0 connectivity.
The monitor therefore provides verified input types and display capability that fit the dual-4K60 dock setup.

Important limitations
- This PASS applies specifically to the Dell Pro Max 16 MC16250, WD22TB4, and two PA279CV monitors at 4K 60 Hz.
- DeskCheck recommends DisplayPort or HDMI for this specific verified 4K60 configuration.
- ASUS notes that the USB-C path is limited to 4K30 when USB transmission is configured for USB 3.2.
- Cable quality and adapter capability still matter.
- PASS does not imply that every laptop connected to the WD22TB4 can run the same monitor configuration.
- PASS reflects documented pre-purchase compatibility and does not guarantee against defective hardware, firmware faults, cable problems, or operating-system issues.
