Description

Dell SE3426DW 34 Inch WQHD 165Hz Curved Gaming Monitor – 1500R VA, 1ms MPRT & FreeSync Premium

The Dell SE3426DW is a premium 34-inch WQHD curved monitor designed for users who want an immersive ultrawide viewing experience combined with smooth gaming performance, vibrant colours and versatile connectivity. With a 3440 × 1440 WQHD resolution, 21:9 aspect ratio, 165Hz refresh rate and 1500R curved VA panel, this monitor provides an expansive workspace and engaging visuals for gaming, entertainment, multitasking and everyday computing.

The high-performance display combines a 1ms MPRT response time, 4ms GTG Fast response time, AMD FreeSync™ Premium, 3000:1 native contrast ratio and 99% sRGB colour coverage. These features help deliver responsive motion, deeper blacks, rich colours and smooth gameplay across compatible systems.

34-Inch WQHD Ultrawide Display

The 34-inch WQHD display provides a resolution of 3440 × 1440 pixels, offering significantly more horizontal workspace than conventional 16:9 monitors.

The 21:9 aspect ratio is particularly useful for immersive gaming, movies and multitasking. Users can work with multiple windows side by side without constantly switching between applications.

The large display area is well suited for:

• PC gaming
• Racing and simulation games
• Movies and streaming
• Productivity
• Multitasking
• Spreadsheets
• Content consumption
• Web browsing
• Home entertainment

With 109 PPI, the display also provides a good balance between screen size and image detail.

1500R Curved VA Panel

The Dell SE3426DW features a 1500R curved VA panel designed to create a more immersive viewing experience.

The curvature helps bring the edges of the large 34-inch display into a more natural position within the user’s field of view. This is particularly beneficial for gaming and entertainment, where the wide screen can create a more engaging visual experience.

The VA panel also provides a strong 3000:1 native contrast ratio, producing deeper blacks and greater separation between dark and bright areas.

165Hz Refresh Rate for Smooth Gaming

With a 165Hz refresh rate, the Dell SE3426DW delivers significantly smoother motion than standard 60Hz displays.

The higher refresh rate is beneficial when playing fast-paced games, navigating large desktop environments or viewing motion-heavy content.

It helps make:

• Camera movement smoother
• Fast action more fluid
• Scrolling more responsive
• Object tracking easier
• Gaming interactions feel more immediate

The monitor can reach its maximum 3440 × 1440 at 165Hz through DisplayPort 1.4 on compatible systems.

1ms MPRT & 4ms GTG Response Time

The Dell SE3426DW supports multiple response-time specifications depending on the selected operating mode:

• 1ms MPRT
• 4ms GTG Fast
• 8ms GTG

The 1ms MPRT mode is designed to improve perceived motion clarity, while the 4ms GTG Fast mode provides responsive pixel transitions for everyday gaming and multimedia.

Combined with the 165Hz refresh rate, the monitor is well suited to fast-paced gaming where smooth and responsive visuals are important.

AMD FreeSync™ Premium

The monitor supports AMD FreeSync™ Premium, helping synchronize the display refresh rate with compatible GPU frame output.

This technology can reduce common gaming issues such as:

• Screen tearing
• Stuttering
• Uneven frame delivery

The monitor also supports Variable Refresh Rate (VRR) through compatible HDMI connections, providing smoother gameplay with supported systems.

3000:1 Contrast Ratio for Deeper Blacks

The 3000:1 native contrast ratio is one of the strengths of the Dell SE3426DW’s VA panel.

A high native contrast ratio helps create deeper blacks and stronger separation between different shades. This can be particularly noticeable in:

• Dark game environments
• Night scenes
• Movies
• Horror games
• Cinematic content
• Shadow-heavy scenes

The result is a more immersive image with greater perceived depth.

99% sRGB Colour Coverage

The Dell SE3426DW offers 99% sRGB colour coverage, allowing it to reproduce a broad range of colours for gaming, entertainment and everyday visual content.

With support for 16.7 million colours and an 8-bit colour depth, the monitor provides vibrant and natural-looking images across compatible applications.

The wide sRGB coverage is suitable for:

• Gaming
• Streaming
• Web content
• Photography viewing
• Presentations
• Everyday creative work

300 Nits Brightness

With 300 cd/m² brightness, the Dell SE3426DW provides clear visibility for typical indoor environments.

The brightness level works well for gaming rooms, home offices, entertainment spaces and general desktop use.

Combined with the anti-glare surface, it helps provide a practical viewing experience under different indoor lighting conditions.

HDR Support for Enhanced Visuals

The Dell SE3426DW supports High Dynamic Range (HDR) through compatible HDMI and DisplayPort connections.

HDR support can enhance compatible games and multimedia content by providing a wider range between darker and brighter areas.

When combined with the VA panel’s strong native contrast and 99% sRGB coverage, HDR-compatible content can appear more dynamic and immersive.

Anti-Glare Display with 3H Hardness

The monitor features an anti-glare surface treatment designed to reduce distracting reflections from surrounding light sources.

The 3H glass hardness provides an additional level of surface durability for everyday use.

The anti-glare coating is particularly useful for users working or gaming in rooms with overhead lighting or nearby windows.

Picture-by-Picture & Picture-in-Picture

The Dell SE3426DW includes both Picture-by-Picture (PBP) and Picture-in-Picture (PIP) functionality.

These features allow users to work with content from multiple sources on the same display.

PBP can be useful for:

• Two computers
• Work + personal PC
• Laptop + desktop
• Gaming + productivity
• Comparing content from different sources

PIP allows one source to be displayed as a smaller window over the primary source.

This makes the monitor particularly useful for multitasking and multi-device workflows.

Flexible HDMI & DisplayPort Connectivity

The Dell SE3426DW provides modern connectivity through:

• 2 × HDMI ports
• 1 × DisplayPort 1.4

The HDMI ports support HDCP 1.4 and HDCP 2.3 and can handle up to 3440 × 1440 at 100Hz, along with HDR and VRR through HDMI 2.1 TMDS.

The DisplayPort 1.4 connection supports up to 3440 × 1440 at 165Hz, with HDR and Display Stream Compression (DSC).

This makes DisplayPort the ideal connection for compatible PCs that need to take full advantage of the monitor’s maximum refresh rate.

Eye Comfort for Extended Viewing

The Dell SE3426DW incorporates several features designed to support comfortable viewing during extended sessions.

Key eye-comfort features include:

• Dell Eye Comfort Technology
• Flicker-Free technology
• Anti-Glare display
• 3-Star Eye Comfort rating

These features make the monitor suitable for users who spend long periods gaming, browsing, working or watching content.

1500R Curvature for Immersive Entertainment

The curved 1500R design is particularly effective on a 34-inch display because it helps maintain a more consistent viewing distance across the wide screen.

This creates an immersive experience for:

• Racing games
• Open-world games
• FPS gaming
• Simulation games
• Movies
• Streaming
• Sports
• Panoramic content

The 21:9 aspect ratio further enhances the sense of immersion by providing additional horizontal viewing space.

Tilt-Adjustable Stand

The supplied stand supports tilt adjustment from -5° to 21°, allowing users to position the screen according to their preferred viewing angle.

Although the included stand focuses on tilt adjustment, the monitor also supports 100 × 100mm VESA mounting for users who want to install it on a compatible monitor arm or wall mount.

VESA Mount Support

The Dell SE3426DW supports the standard 100 × 100mm VESA mounting pattern.

VESA compatibility allows users to:

• Install a monitor arm
• Wall mount the display

• Configure a multi-monitor workstation

This provides additional flexibility beyond the included stand.
