Pros
- Very good overall performance, particularly in video call
- Accurate camera depth of field and low noise level
- Very good audio capture performance (good intelligibility and filtering out of background noise)
- Good overall display readability
Cons
- Hue shifting can occur, affecting skin tone accuracy
- Limited in situations when voices overlap or are too quiet
- Colors lack fidelity and saturation in HDR
- Not especially suited for music & video playback purposes
The new Dell Latitude 9440 2-in-1 reaches first place among Windows laptops in our rankings, just like the Dell Latitude 7340 2-in-1, with both devices featuring a consistent performance among camera, display, and audio tests. Both are especially well-suited for video call applications, with very good audio capture, a good display brightness range, and a camera with an accurate depth of field for the usual distances from the laptop. Audio performance is limited when voices overlap or are too quiet, and neither device is especially suited for media playback, with HDR colors lacking in fidelity and saturation, and audio timbre lacking in bass and body.
Test summary
About DXOMARK Laptop tests: For scoring and analysis in our laptop reviews, DXOMARK engineers perform a variety of objective tests and undertake more than 20 hours of perceptual evaluations under controlled lab conditions and real-life scenarios.

About DXOMARK Laptop tests
DXOMARK's Video call use case is a score that evaluates how a device handles video calls and videoconferencing in multiple conditions. This score focuses on the camera performance and the capture and playback rendering of voices. Read more about how we test the use cases of Video call score here.
The camera on the Latitude 9440 2-in-1 laptop has a depth of field that is well calibrated to the most common camera-to-face distances on laptops, along with generally accurate target exposure. Skin-tone rendering is sometimes inaccurate and clipping in bright areas is often visible.
Hue shift near saturation and aliasing are sometimes noticeable as well. Focused on mainly front sound sources, the device achieves excellent voice intelligibility for video calls, although the efficient SNR can sometimes remove quiet voices and the duplex experience is impaired by gating. The display has a nice brightness range that results in good overall readability.

Camera texture acutance on Deadleaves with illuminance levels
This graph shows the evolution of texture acutance with the level of lux measured on a Deadleaves chart.
The following graphs show the objective measurements performed in our camera labs:
Camera visual noise evolution with illuminance levels
This graph shows the evolution of spatial visual noise with the level of lux. Spatial visual noise is measured on the visual noise chart in the video noise setup. DXOMARK visual noise measurement is derived from ISO15739 standard.
Target exposure on face with illuminance levels
These measurements take place on a setup combining realistic mannequins and a backlit panel simulating high dynamic range conditions. This graph shows the evolution of lightness measured on the forehead of the realistic mannequin with the level of lux, for multiple lighting conditions. The lightness is measured in L*. Delta EV specifies the difference of luminance in stops between the face and the light panel simulating HDR conditions.
Target exposure on face with illuminance levels in HDR conditions
These measurements take place on a setup combining realistic mannequins and a backlit panel simulating high dynamic range conditions. This graph shows the evolution of lightness measured on the forehead of the realistic mannequin with the level of lux, for multiple lighting conditions. The lightness is measured in L*. Delta EV specifies the difference of luminance in stops between the face and the light panel simulating HDR conditions.

Audio capture scores comparison
The following graphs show the frequency response, distortion and directivity in capture, recorded in our semi-anechoic room:
Audio capture frequency response
A 1/12 octave frequency response graph, which measures the volume of each frequency captured by the laptop when recording an objective test signal at 1 meter in an anechoic environment.
Audio capture directivity
Directivity graph of the laptop microphone(s) when capturing test signals using the camera app. It represents the acoustic energy (in dB) over the angle of incidence of the sound source (normalized to the angle 0°, in front of the device).
About DXOMARK Laptop tests
DXOMARK's Video and Music use case score evaluates the capability of a device to reproduce multimedia usages such as videos, movies and music playback in indoor conditions. This score focuses on the display performance and audio-playback rendering. Read more about how we test this use case here.
The 9440 2-in-1’s display achieves more than 500 nits of brightness, providing good readability in all lighting conditions. It correctly renders color and adapts its gamut for SDR videos; for HDR content, however, its gamut is narrow and colors lack fidelity and saturation. The display’s minimum brightness of 36 nits is too high for comfortable use in a low-light environment. The laptop’s sound lacks bass and body, making it a less suitable device for playing music and videos.
The following chart presents the display subscores for the multimedia use case:
Display scores comparison
The following graphs show the objective measurements performed in our display lab:
Display gamut coverage for video contents
The primary colors are measured both in HDR10 and SDR. The extracted color gamut shows the extent of the color area that the device can render. To respect the artistic intent, the measured gamut should match the master color space of each video.
Display reflectance measurement (SCI)
Measurements above show the reflection of the device within the visible spectrum range (400 nm to 700 nm). It includes both diffuse and specular reflection.
