Head-to-head
ASUS PA278CV vs Dell U2724DE: Dell expands the docking job, ASUS suits a simpler 65W laptop setup
The short answer
Choose U2724DE for 120Hz, Thunderbolt and a fuller desk hub. PA278CV suits a simpler USB-C work setup where 65W charging and 75Hz are sufficient.
Before you choose
The reasoning and the trade-offs
Compare detail at the actual screen size
PA278CV works out to about 108.8 pixels per inch, versus 108.8 for U2724DE. Their pixel densities are close enough that layout and connection needs are stronger separators.
What this is based on
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 27 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.
Main trade-off
Dell UltraSharp 27 Thunderbolt Hub Monitor
The native panel is QHD up to 120Hz. Thunderbolt upstream carries video/data and up to 90W only with a compatible host and cable. The separate USB-C upstream is data only, so HDMI/DP hosts also need their video cable and correct USB Selection. Auto KVM requires PBP Off, Auto Select On and Auto Select for Thunderbolt Yes. The USB Switch shortcut is PBP-only.

Winner by situation
Start with what you need it to do
Use a simple USB-C laptop setup
PA278CV combines QHD at 75 Hz with up to 65 W USB-C charging. Those limits need to cover the selected laptop and daily work.
- ASUS ProArt Display 27-inch USB-C
- Better fit
- Dell UltraSharp 27 Thunderbolt Hub Monitor
- Depends
Connect Thunderbolt peripherals
U2724DE adds a Thunderbolt-centered hub, KVM and 2.5 Gb Ethernet. A USB-C connector alone does not establish the same peripheral capabilities.
- ASUS ProArt Display 27-inch USB-C
- Depends
- Dell UltraSharp 27 Thunderbolt Hub Monitor
- Better fit
Prefer the ProArt stand and controls
PA278CV provides the ProArt control arrangement and a stand with 150 mm of height adjustment. Confirm the resulting screen position rather than treating adjustment range as final height.
- ASUS ProArt Display 27-inch USB-C
- Better fit
- Dell UltraSharp 27 Thunderbolt Hub Monitor
- Depends
Need 90W charging and 120Hz motion
U2724DE offers up to 90 W and 120 Hz at QHD. PA278CV stops at 65 W and 75 Hz, so it cannot meet either higher required ceiling.

What matters in practice
The differences that matter
Compare detail at the actual screen size
PA278CV works out to about 108.8 pixels per inch, versus 108.8 for U2724DE. Their pixel densities are close enough that layout and connection needs are stronger separators.
How we reached this conclusion
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 27 inches and 2560 × 1440 at 27 inches. Published nominal diagonals make these approximate.
Separate native detail from game speed
PA278CV draws 3.7 million native pixels per frame and U2724DE 3.7 million. Their refresh ceilings are 75Hz and 120Hz respectively.
How we reached this conclusion
Native pixels = width × height. Refresh interval =1000 / Hz, giving 13.3 and 8.3 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
Dell adds 25W of charging headroom without adding pixels
U2724DE raises rated delivery from 65 to 90W and refresh from 75 to 120Hz at unchanged QHD resolution.
How we reached this conclusion
90 - 65 = 25W. 120 - 75 = 45Hz. Both panels have 2560 × 1440 pixels.
Choice A
ASUS, PA278CV
ProArt Display 27-inch USB-C
A QHD ProArt display keeps text comfortably sized and supplies up to 65 watts through the same cable used for video. The adjustable stand and DisplayPort output suit a work desk that may grow.
- Best matched use
- Design and office work from a modest-power USB-C laptop
Checked facts
- 27-inch 2560 by 1440 IPS panel at 75Hz
- USB-C video with up to 65 watts and DisplayPort output
- 150 mm height adjustment and a 615 by 228 mm stand footprint
Choice B
Dell, U2724DE
UltraSharp 27 Thunderbolt Hub Monitor
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.
- Best matched use
- A compatible Thunderbolt laptop desk with QHD video, conditional charging and wired networking
Checked facts
- 27-inch 2560 by 1440 IPS Black panel at 120Hz
- Thunderbolt 4 with up to 90-watt power delivery
- DisplayPort output and 2.5GbE networking
Meaningful differences
What changes the fit
| What changes | ASUS ProArt Display 27-inch USB-C | Dell UltraSharp 27 Thunderbolt Hub Monitor | Why it matters |
|---|---|---|---|
| Native resolution | 2560 × 1440 | 2560 × 1440 | Operating-system scaling changes usable logical workspace. |
| Panel diagonal | 27 in | 27 in | A nominal screen class may differ slightly from the measured active diagonal. |
| Maximum refresh | 75Hz | 120Hz | Check the exact input, resolution and overclock conditions. |
| Panel technology | IPS | IPS Black | Panel type alone does not establish a measured color or motion winner. |
| Laptop power | Up to 65W | Up to 90W | Host, cable and negotiated power profile must support the desired delivery. |
| Chassis width | 615 mm | Check exact drawing | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | 228 mm | Check exact drawing | The included stand can take more desk depth than the display cabinet. |
What you give up
Every choice has a cost
If you choose ASUS ProArt Display 27-inch USB-C
- DisplayPort daisy chaining depends on the laptop and operating system, especially on a Mac.
If you choose Dell UltraSharp 27 Thunderbolt Hub Monitor
- RJ45 needs upstream data, the correct Realtek driver and a separately purchased Ethernet cable. DP Alt High Resolution can limit USB data to 480 Mbps, so full 2.5GbE throughput is not promised. More-than-90W laptops need their own supply. Confirm off-mode charging settings and the 612.24 mm width plus 192.28 mm stand depth.
What matters in practice
How to make the call
Resolution does not change between these choices
Both are 27-inch QHD panels. Dell extra capability goes into connectivity and refresh rather than a sharper native image.
Charging needs can rule out the simpler setup
The ceilings are 65W and 90W. A laptop that regularly needs more than 65W may drain its battery under load on ASUS even while showing a charging symbol.
The hub can replace several separate pieces
Dell adds a KVM and 2.5Gb Ethernet alongside Thunderbolt. Those benefits depend on the computer, cables and network actually using them.
What this comparison cannot tell you
- Pixel density and refresh intervals are calculations from published specifications, not a measured visual-quality or latency test.
- USB-C power is a maximum negotiated ceiling. It does not promise full-speed charging for every laptop.
