Pros
- Very good overall performance, particularly in video calls
- Very good audio capture performance
- Good display readability
- Good and accurate color rendering from camera
Cons
- Limited in duplex situations (gating when voices overlap) and when voices are too quiet
- Colors lack fidelity and saturation in HDR; inconsistent color accuracy overall
- Not especially suited for music & video audio purposes
The new Dell Latitude 7340 2-in-1 currently reaches first place among Windows laptops in our rankings. Like the brand-new Dell Latitude 9440 2-in-1, the 7340 2-in-1 features a consistent performance among audio, camera and display tests, and is especially well suited for video call applications. It has great audio capture and its display has a good brightness range, ensuring good overall readability. Similar to the 9440 model, the 7340 is not especially suited for multimedia audio playback because its timbre underperforms in the lower frequencies.

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.
The Dell 7340 2-in-1’s camera provides accurate color rendering most of the time, although color shading is visible. Targets are significantly underexposed in backlit scenes. The display has a good brightness range, although colors are not always accurate. With a front-facing focus, the device has very good audio capture, enhancing intelligibility and leaving out background noise in most situations. Its performance is somewhat limited when voices overlap, with obvious gating in duplex situations, and the built-in microphones don’t always pick up quiet voices.

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.
The 7340’s display offers correct color rendering and gamut adaptation for SDR videos, and its more than 500 nits of brightness ensures satisfactory readability in all ambient lighting. For HDR content, however, the gamut is narrow, and even very saturated colors appear faded.
The display’s minimum brightness is 32 nits, which is too high for comfortable use in a low-light environment. The lack of bass and body in audio contributes to a generally sub-par music and video playback performance.
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.
