Main trade-off
ASUS ProArt Display 27-inch 4K
No integrated RJ45 or equivalent built-in KVM is documented.
Head-to-head
Choose PA279CRV when 4K detail and documented Adobe RGB coverage lead the brief. Choose U2724DE when a 120Hz QHD screen, Ethernet and built-in KVM can replace separate desk accessories. Both can power compatible laptops, but the Dell's docking connections and the ASUS's pixel density serve different working days.
Before you choose
U2724DE's KVM can move the attached keyboard and mouse between two connected hosts, but the second computer also needs its USB data connection. Switching video alone is insufficient.
What this is based on
A KVM requires video and USB paths for each host. Dell documents the KVM and additional upstream connection. A generic USB hub does not establish that function.
Main trade-off
No integrated RJ45 or equivalent built-in KVM is documented.
Main trade-off
QHD cannot show a complete 4K frame at 1:1 mapping.


Compare PA279CRV and U2724DE for a detailed 4K workspace, a wired laptop dock and sharing a keyboard between two computers.
Choose PA279CRV when 4K detail and documented Adobe RGB coverage lead the brief. Choose U2724DE when a 120Hz QHD screen, Ethernet and built-in KVM can replace separate desk accessories. Both can power compatible laptops, but the Dell's docking connections and the ASUS's pixel density serve different working days.
Winner by situation
The QHD Dell cannot display every 4K source pixel simultaneously at 1:1.
Dell has a KVM, with both host USB paths required.
Dell has integrated RJ45. ASUS does not list one.
Dell reaches 120Hz. ASUS reaches 60Hz.
What matters in practice
U2724DE's KVM can move the attached keyboard and mouse between two connected hosts, but the second computer also needs its USB data connection. Switching video alone is insufficient.
A KVM requires video and USB paths for each host. Dell documents the KVM and additional upstream connection. A generic USB hub does not establish that function.
Dell's RJ45 socket provides a documented 2.5GbE network path through the monitor's host connection. PA279CRV has no RJ45 socket in its listed ports, so a wired laptop needs its own adapter or dock.
Dell includes 2.5GbE Ethernet. Its rate is a link capability, subject to the network and host path, rather than a guaranteed internet speed.
A 3840-by-2160 image can occupy the full native pixel grid on PA279CRV. U2724DE has 2560 by 1440 pixels, so viewing the whole 4K frame requires resampling, while 1:1 inspection shows only part at once.
The source example is 3840 by 2160. The consequence follows from each native grid, not a tested judgment of sharpness or a promise about software scaling.

ASUS, PA279CRV
A compact 4K ProArt screen brings wide-gamut factory calibration, 96-watt USB-C power and display chaining to a creator desk.

Dell, U2724DE
Dell U2724DE is a 27-inch native QHD monitor up to 120Hz. A verified Thunderbolt host can use video, data and up to 90W through its proper upstream. Separate USB-C upstream is data only. RJ45 needs upstream data, driver and Ethernet cable, with DP Alt High Resolution limiting USB data to 480 Mbps.
Meaningful differences
| What changes | ASUS ProArt Display 27-inch 4K | Dell UltraSharp 27 Thunderbolt Hub Monitor | Why it matters |
|---|---|---|---|
| Resolution and refresh | 3840 by 2160 at 60Hz | 2560 by 1440 at 120Hz | Choose detail or a higher refresh ceiling without assuming either changes application layout automatically. |
| Laptop power | USB-C up to 96W | Thunderbolt 4 up to 90W | Neither automatically replaces a laptop charger above its compatible negotiated ceiling. |
| Ethernet in the monitor | No RJ45 in documented port list | 2.5GbE RJ45 | Dell can bring a wired network through the host connection. |
| Two-computer peripheral switching | No equivalent built-in KVM documented | Built-in KVM | Dell can switch attached USB peripherals after both host paths are connected. |
| Display expansion | DisplayPort MST output | Thunderbolt downstream and DisplayPort output | Host and operating-system support still determine the working chain. |
What you give up
Recommendation switch
Choose ASUS ProArt Display 27-inch 4K. PA279CRV has the matching 3840-by-2160 native grid.
Choose Dell UltraSharp 27 Thunderbolt Hub Monitor. U2724DE provides a documented KVM arrangement.
What matters in practice
U2724DE's KVM can move the attached keyboard and mouse between two connected hosts, but the second computer also needs its USB data connection. Switching video alone is insufficient. Choose Dell if a work laptop and personal desktop routinely share those peripherals. PA279CRV has a USB hub, but its documented setup does not provide the same built-in KVM route, so budget a separate switching arrangement.
Dell's RJ45 socket provides a documented 2.5GbE network path through the monitor's host connection. PA279CRV has no RJ45 socket in its listed ports, so a wired laptop needs its own adapter or dock. Choose Dell when that existing dongle is one of the items you want to remove. If the laptop already uses a suitable dock, ASUS's 4K screen may be the more useful change.
A 3840-by-2160 image can occupy the full native pixel grid on PA279CRV. U2724DE has 2560 by 1440 pixels, so viewing the whole 4K frame requires resampling, while 1:1 inspection shows only part at once. Choose ASUS for that specific image-inspection job. Choose Dell if QHD is enough for the workspace and the 120Hz ceiling or docking connections matter more.
