Aspect ratio

Dell Alienware AW3426DW
5.0
The 21:9 canvas creates a wide, cinematic view and extra horizontal working space. Not every game or console output fills it cleanly.
Backlight bleed control
Dell Alienware AW2725DF
5.0
OLED pixels eliminate the conventional LCD backlight bleed that can wash out dark corners, keeping black areas clean.

Dell Alienware AW3426DW
2.0
Unlike some higher-priced rivals, this model omits a black-frame-insertion option for further reducing perceived blur.
Curved screen immersion
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.6
The gently curved 34-inch screen gives games a wider, immersive feel without the distortion of more aggressive curves. A few people would prefer an even deeper wraparound.
Firmware updateability
Dell Alienware AW2725DF
4.5
Firmware can be updated through Dell's tools, and an update apparently resolved one instance of intermittent gray-screen failures. The update process adds another setup step.

Gradient smoothness
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.5
Most real-world gradients look smooth with little banding, but near-black fades can reveal coarser steps in some HDR settings.
HDR mode versatility
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.3
True Black, Peak 1300, Peak 1300 Bright and Dolby Vision give users several looks to choose from. None perfectly balances peak punch with accuracy in every scene.
Headphone output quality
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
1.2
With no headphone or audio-out connection on the monitor, wired audio must run directly from a computer, console or another device.
Heat management
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
3.8
Passive cooling avoids fan noise; one side-by-side tester measured more warmth at maximum output but found better temperature behavior at matched brightness.
Image scaling
Dell Alienware AW2725DF
2.0
Downscaled virtual-4K modes can help some HDMI devices, but the resulting 1440p image and restricted output modes limit their usefulness.

Dell Alienware AW2725DF
3.5
The supplied stand, signal cables and accessories make setup convenient, although the missing HDMI cable in some kits is criticized.

Integrated power supply
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
5.0
A direct power cord avoids a bulky external brick, helping keep the desk and floor tidier.
OLED motion blur reduction
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
5.0
The extremely fast OLED pixels reduce smearing and ghosting, keeping movement crisper than typical LCD screens at comparable refresh rates.
Packaging presentation
Dell Alienware AW2725DF
3.5
The packaging usually protects the panel well, although at least one unboxing showed conspicuous box damage.
Dell Alienware AW3426DWNo score yet
Premium feel
Dell Alienware AW2725DF
4.5
The clean styling and polished thin panel give a premium first impression, though plastic construction tempers the luxury feel.

Productivity versatility
Dell Alienware AW2725DF
3.0
The display can handle occasional desktop tasks, but OLED wear concerns and text rendering prevent it from being the most comfortable all-day work monitor.
Dell Alienware AW3426DWNo score yet
Shadow detail
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
3.5
Dark-shade handling is usually good and can be improved with presets, though some HDR modes crush or coarsen the very darkest steps.
Sleep and wake behavior
Dell Alienware AW2725DF
1.0
A small number of experiences describe serious picture-loss or maintenance-cycle problems that interrupt use, despite otherwise positive day-to-day operation.
Dell Alienware AW3426DWNo score yet
Ultrawide gaming experience
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.9
A wider field of view and gentle curvature add real immersion in compatible PC games, with black bars or unsupported scenes remaining occasional frustrations.
USB port accessibility
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.8
Bottom-edge USB-A and USB-C ports are easy to reach without feeling behind the monitor, though permanently attached cables can be visible.
Video cadence compatibility

Dell Alienware AW3426DW
5.0
Common 24, 25, 50 and 60 fps video plays without obvious skips or cadence judder.
Performance
Adaptive sync performance
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
5.0
Adaptive Sync, G-SYNC, and FreeSync keep gameplay fluid and largely tear-free. A few accounts distinguish this smoothness from occasional OLED VRR flicker.
Esports display mode
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.1
A simulated 25-inch active area makes fast competitive play easier to focus on while retaining 280Hz. A few testers saw dimmer output or questioned whether the smaller image was worth it.
Local dimming performance
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
5.0
Pixel-level control makes bright and dark areas coexist cleanly without the blooming associated with zone-based backlights.
Picture-in-picture and picture-by-picture
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.6
PiP/PbP options are genuinely useful for split-screen viewing and working across two inputs, with convenient positioning controls.
Ownership and support
Content aspect-ratio support
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
2.5
Many PC titles benefit from the wider view, but unsupported games, menus and cutscenes still introduce black bars, cropping or smaller active images.
Dolby Vision support
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
4.2
Dolby Vision adds useful flexibility for compatible games, consoles and movies, although PC support is spotty and mode behavior sometimes needs attention.
HDMI 2.1 support
Dell Alienware AW2725DF
1.9
The HDMI connection is the standout connectivity compromise: despite HDMI 2.1 labeling, its bandwidth is restricted and it cannot carry native 1440p at 360Hz.
Dell Alienware AW3426DWNo score yet
Reliability over time
Dell Alienware AW2725DF
1.7
Long-term confidence is mixed: isolated reports describe freezes, lost pictures and exchanges, while a firmware update resolved one reported gray-screen issue.

Controls and connectivity
HDR adjustment controls
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
2.7
Multiple HDR modes are available, but limited brightness-curve adjustments and locked controls restrict fine tuning.
Comfort and build
PWM flicker comfort
Dell Alienware AW2725DFNo score yet
Dell Alienware AW3426DW
2.0
One test found a PWM frequency that may bother especially sensitive viewers, even while typical gaming looked fine.
