Choose the Dell U2723QE if its Ethernet/KVM hub is your priority; shortlist the ASUS PA279CRV if published Adobe RGB coverage matters to your work. Both support DisplayPort daisy chaining. These are task-based inferences from the specifications below, not a hands-on winner.
This is a research-based comparison, checked September 8, 2026. We have not measured either monitor’s color accuracy, contrast, uniformity, input lag or reliability. Prices and stock are not tracked here; compare current quotes for the exact model and condition.

Choose by the job, not the brand
| Your requirement | Shortlist first | Check before ordering |
|---|---|---|
| Wired Ethernet and two computers sharing keyboard/mouse | Dell U2723QE | Draw both video and USB upstream paths; a video cable alone does not connect USB peripherals |
| A workflow requiring published Adobe RGB coverage | ASUS PA279CRV | Match your application, working color space and calibration procedure; coverage alone is not accuracy |
| Higher manufacturer-rated typical contrast | Dell U2723QE | Treat the rating as a specification, not our dark-room measurement |
| Two extended displays from one Windows connection | Either, conditionally | Confirm GPU/MST support, bandwidth and monitor settings; see the checklist below |
| A 120Hz refresh-rate requirement | Neither | Both exact models are 60Hz; do not confuse U2723QE with U2725QE |

Correction to our earlier comparison: PA279CRV is not a 95% DCI-P3 display without daisy chaining. ASUS lists 99% DCI-P3, 100% sRGB and a DisplayPort MST output. ASUS model details.
Daisy-chain compatibility: monitor support is only one part
A possible wiring plan is computer → monitor 1 USB-C/DP input → monitor 1 DP output → monitor 2 DP input. It needs a compatible source and settings; the diagram is not a tested configuration.
- Verify the host. Confirm the GPU, OS and chosen port support MST, plus the required resolution, refresh rate and color depth. USB-C connector shape alone is insufficient. Higher-bandwidth modes and USB-data prioritization can reduce what fits on a shared link. Dell’s current daisy-chain guide.
- Set the ASUS correctly. Its manual requires an MST-capable source and Power Saving → Normal Level for daisy chaining. Deep Level produces cloned content in the described chain, and connecting DP output fixes the selected input instead of auto-detecting. PA279CRV user guide, section 1.3.3 and Settings.
- Check the Dell MST menu and source bandwidth. The U2723QE manual describes DP/USB-C MST connections and DSC support. Do not assume every USB-C laptop can drive two 4K screens at the desired mode. U2723QE user guide, “Connecting Your Monitor”.
- Separate Mac compatibility from Windows MST. Dell documents duplicate-only macOS output for DisplayPort and USB-C DP Alt Mode chains. Neither monitor is a Thunderbolt hub. For an extended Mac desktop, investigate separate connections within your exact Mac’s native display limit; do not buy either expecting its MST output to supply that feature. Dell’s connection-mode table, Dell’s Mac USB-C guidance.
Practical checks before you pay
Record your laptop model, chosen port, charging requirement, both displays’ target modes and the peripherals you intend to use. Compare the complete quote, including any missing cables, adapter or arm, rather than assuming one brand is always cheaper.
During the return window, use your own editor or photo project to evaluate readable scaling, charging under load, USB switching and wake-from-sleep behavior. These are suggested acceptance checks, not results we have obtained. Keep a record of the seller’s return and pixel-defect terms.
For physical fit, use the desk and clamp dimension checker with measured desktop thickness and rear clearance. It checks geometry only: separately confirm display weight without stand, mounting hardware and the arm manufacturer’s limits. The work-monitor checklist helps turn these checks into a shortlist.

Frequently asked questions
Does the ASUS PA279CRV support daisy chaining?
Yes. It has a DisplayPort MST output. ASUS requires an MST-capable source and Power Saving set to Normal Level. Host bandwidth, operating system and display settings still determine the available extended-display modes.
Does the PA279CRV have less DCI-P3 coverage than the U2723QE?
No. ASUS publishes 99% DCI-P3 coverage for PA279CRV; Dell publishes 98% for U2723QE. Both list 100% sRGB. These are manufacturer specifications, not color measurements made by FindPicked.
Can either monitor provide a two-screen extended MST desktop on a Mac?
Do not plan an extended Mac desktop through either monitor’s DisplayPort MST chain. Dell documents duplicate-only output for macOS over DisplayPort or USB-C DP Alt Mode. Check separate display connections and the exact Mac model’s display limit instead.
