ASUS ProArt PA279CRV vs ROG Strix XG27ACS

Choose by the mode and power you actually need: the PA279CRV lists 4K at up to 60Hz and 96W USB-C Power Delivery; the XG27ACS lists QHD at up to 180Hz through DisplayPort/USB-C (144Hz through HDMI) and 7.5W USB-C Power Delivery. This comparison does not test image quality, response, or gaming performance.

The buying question

Should the display match a 4K 60Hz workflow, a QHD high-refresh workflow, or a laptop's USB-C charging requirement?

The PA279CRV lists 3840 × 2160 at up to 60Hz and USB-C Power Delivery up to 96W. The XG27ACS lists 2560 × 1440 at up to 180Hz over DisplayPort or USB-C, up to 144Hz over HDMI, and USB-C Power Delivery up to 7.5W. These are different source/display and laptop-power targets, not measured quality results.

Quick verdict

Choose ASUS ProArt Display PA279CRV if

  • You need the PA279CRV's listed 3840 × 2160 resolution at up to 60Hz.
  • You want a monitor with listed USB-C Power Delivery up to 96W, and that output matches your laptop's charging needs.

Choose ASUS ROG Strix XG27ACS if

  • You want the XG27ACS's listed 2560 × 1440 mode with up to 180Hz over DisplayPort or USB-C, or up to 144Hz over HDMI, and your source supports it.
  • A 7.5W USB-C output is suitable for the device you intend to connect, or you will use separate device power.

When to skip: You require a documented 4K refresh rate above 60Hz, or you require the monitor itself to provide more than 96W USB-C Power Delivery.
When the recommendation changes
  • If your host, cable, application, or game cannot output the selected resolution and refresh rate, the display specification alone does not guarantee that mode.
  • If your laptop needs more USB-C power than the display supplies, plan to use its normal power adapter; verify the laptop's required input and the monitor's charging behavior before relying on one-cable power.
  • If you require 4K above 60Hz, neither model's listed maximum display mode meets that requirement.

The differences that matter

Resolution Refresh Input Workflow

ASUS ProArt Display PA279CRV

The PA279CRV is listed at 3840 × 2160 resolution with maximum refresh rate 60Hz.[1]

ASUS ROG Strix XG27ACS

The XG27ACS is listed at 2560 × 1440 with maximum refresh rate 180Hz; ASUS lists USB-C/DisplayPort vertical frequency up to 180Hz and HDMI up to 144Hz.[2]

What this changes: These published modes support distinct source/display requirements: 4K up to 60Hz versus QHD up to 180Hz through USB-C/DisplayPort or up to 144Hz through HDMI. The supported mode still depends on the connected host and cable.[1, 2]

The better fit depends on your priorities

Connection Power Workflow

ASUS ProArt Display PA279CRV

The PA279CRV lists one USB-C port with DisplayPort Alt Mode and USB-C Power Delivery up to 96W.[1]

ASUS ROG Strix XG27ACS

The XG27ACS lists one USB-C port with DisplayPort Alt Mode and USB-C Power Delivery at 7.5W.[2]

What this changes: A buyer planning to power a laptop from the display should compare the laptop's required input against these published output figures; no universal charging result is inferred.[1, 2]

The better fit depends on your priorities

Best for your routine

A buyer whose required computer mode is 3840 × 2160 at up to 60Hz, with no requirement for a higher 4K refresh rate.

Best fit: ASUS ProArt Display PA279CRV

Based on listed features, not comparative testing.

The PA279CRV's exact-model ASUS specification lists 3840 × 2160 and a 60Hz maximum. This is a mode-fit recommendation, not a measured quality winner.

A buyer targeting 2560 × 1440 at high refresh and whose source supports the selected connection's mode.

Best fit: ASUS ROG Strix XG27ACS

Based on listed features, not comparative testing.

The XG27ACS exact-model specifications list 180Hz over DisplayPort/USB-C and 144Hz over HDMI. Verify the host and cable can produce the desired mode.

A laptop-desk buyer who wants USB-C display connection and needs to compare monitor power against the laptop's charging requirement.

The better fit depends on your priorities

The published power outputs differ, but the right fit depends on the laptop's required power and whether a separate adapter is acceptable.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Prices shown on this page have their own observation times and do not establish a comparable checkout price. Consider any current price difference alongside the display mode and USB-C power requirement that matter to your setup.

Confirm current checkout offers, including condition, seller and shipping, before purchase.

Limitations

  • This is a feature-fit comparison based on the manufacturers' specifications; Pickoryx did not conduct hands-on or controlled side-by-side testing.
  • Resolution and refresh specifications do not establish image quality, color accuracy, motion clarity, response, or gaming performance. No measured winner is claimed.
  • The computer's graphics output, cable, operating system, and selected input can limit available display modes. Verify the complete setup against the exact mode you need.
  • USB-C Power Delivery values are published maximums; the connected device's requirements and charging behavior determine whether either display can power it as intended.
  • Prices and availability can change after their stated observation times. Confirm the exact seller listing, condition and included accessories before purchase.

Questions shoppers ask

Does the XG27ACS run at 180Hz through every input?

No. ASUS lists a 48–180Hz vertical signal range for USB-C and DisplayPort, and 48–144Hz for HDMI. The computer and cable must also support the chosen mode.

Can either monitor replace my laptop charger over USB-C?

Check the laptop's power requirement. ASUS lists up to 96W USB-C Power Delivery for the PA279CRV and 7.5W for the XG27ACS; those figures do not guarantee charging behavior for every laptop.

Which is better for gaming or color work?

The specifications support different resolution and refresh targets, but this comparison includes no controlled measurements of gaming performance or color accuracy. Choose based on your required mode and independently verify the performance characteristics your work depends on.

Methodology and sources

Compared only manufacturer-published maximum resolution and refresh modes by input, and USB-C DisplayPort Alt Mode and Power Delivery ratings. No product performance was measured.

Automation assisted with organizing source facts and drafting; neither display was physically tested.
