Head-to-head
Choose U2724DE for smoother motion and a Thunderbolt-centered desk. U2723QE offers denser 4K text and more pixels at the same 27-inch size.
Before you choose
U2724DE works out to about 108.8 pixels per inch, versus 163.2 for U2723QE. A denser panel can draw finer text at the same logical size, while comfortable scaling determines workspace.
What this is based on
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 27 inches and 3840 × 2160 at 27 inches. Published nominal diagonals make these approximate.
Main trade-off
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.
Main trade-off
Its USB-C upstream connection is not Thunderbolt.
Choose U2724DE for smoother motion and a Thunderbolt-centered desk. U2723QE offers denser 4K text and more pixels at the same 27-inch size.
This is resolution versus refresh, not a simple generation upgrade
Winner by situation
U2724DE reaches 120 Hz at QHD, while U2723QE reaches 60 Hz at 4K. The higher refresh choice comes with fewer native pixels.
U2723QE provides 3840 × 2160 pixels at 27 inches, against 2560 × 1440 for U2724DE. Text scaling determines how that higher density appears.
U2724DE supplies Thunderbolt and 2.5 Gb Ethernet, compared with U2723QE's 1 Gb Ethernet. The host, network and destination must support the faster route.
U2723QE combines a 4K panel with a 60 Hz ceiling. It offers more native detail when the workflow does not require the U2724DE's 120 Hz motion.
What matters in practice
U2724DE works out to about 108.8 pixels per inch, versus 163.2 for U2723QE. A denser panel can draw finer text at the same logical size, while comfortable scaling determines workspace.
Pixels per inch = √(width² + height²) / diagonal. Inputs are 2560 × 1440 at 27 inches and 3840 × 2160 at 27 inches. Published nominal diagonals make these approximate.
U2724DE draws 3.7 million native pixels per frame and U2723QE 8.3 million. Their refresh ceilings are 120Hz and 60Hz respectively.
Native pixels = width × height. Refresh interval =1000 / Hz, giving 8.3 and 16.7 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
U2723QE renders 8.29 million pixels versus 3.69 million on U2724DE, while the latter doubles refresh.
3840 × 2160 / (2560 × 1440) = 2.25. 120 / 60 = 2. Pixel load and refresh are separate.
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.
Dell, U2723QE
A sharp 4K panel, Ethernet and a USB hub make the U2723QE useful for a laptop that spends most days at a desk. Its 90-watt connection is more important than a newer model number if it covers your laptop's needs.
Meaningful differences
| What changes | Dell UltraSharp 27 Thunderbolt Hub Monitor | Dell UltraSharp 27 4K USB-C Hub Monitor | Why it matters |
|---|---|---|---|
| Native resolution | 2560 × 1440 | 3840 × 2160 | 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 | 120Hz | 60Hz | Check the exact input, resolution and overclock conditions. |
| Panel technology | IPS Black | IPS Black | Panel type alone does not establish a measured color or motion winner. |
| Laptop power | Up to 90W | Up to 90W | Host, cable and negotiated power profile must support the desired delivery. |
| Chassis width | Check exact drawing | Check exact drawing | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | Check exact drawing | Check exact drawing | The included stand can take more desk depth than the display cabinet. |
What you give up
What matters in practice
U2724DE is 2560 by 1440 at 120Hz. U2723QE is 3840 by 2160 at 60Hz. The newer-looking name does not imply more pixels.
Each lists 90W delivery. That shared figure removes charging wattage as a reason to choose one, though cable and host support still matter.
U2724DE has 2.5Gb Ethernet against 1Gb on U2723QE. A faster port only helps when the network, host link and destination can exceed gigabit.
