Dell 5K 40-inch UltraSharp Curved Thunderbolt Hub Monitor (U4025QW): Technical Deep Dive


The new Dell 5K 40-inch UltraSharp Curved Thunderbolt Hub Monitor (U4025QW) boasts impressive technical specifications, catering to professionals demanding exceptional visuals, smooth performance, and extensive connectivity.


Technical aspects:



  • Panel Technology: This monitor utilizes an IPS (In-Plane Switching) panel. IPS panels offer wide viewing angles (typically 178 degrees), good color accuracy, and decent response times, making them well-suited for various tasks, including photo editing, video editing, and gaming.
  • Resolution: The star of the show is the stunning 5K resolution (5120 x 2160), delivering incredibly sharp visuals and ample screen real estate for multitasking. This high resolution translates to a pixel density of 140 pixels per inch (PPI), ensuring crisp details and text readability.
  • Color Accuracy: Dell claims the monitor offers 98% DCI-P3 color gamut coverage, indicating excellent color reproduction, crucial for creative professionals working with color-critical tasks.
  • HDR (High Dynamic Range): This monitor does not explicitly mention HDR support in its specifications. While some sources claim HDR compatibility, it’s advisable to confirm this detail with Dell directly or through reliable product reviews.
  • Refresh Rate: The monitor boasts a 120Hz refresh rate. This translates to smoother visuals, especially noticeable in fast-paced content like games and videos. However, keep in mind that achieving 120Hz might require a compatible graphics card and DisplayPort connection.



  • Thunderbolt 4 ports: The monitor features two Thunderbolt 4 ports, offering a versatile connection solution. These ports support data transfer speeds of up to 40 Gbps, allowing you to connect high-performance devices and daisy-chain up to two additional 4K displays.
  • Other ports: The monitor also includes an HDMI 2.1a port, a USB 3.2 Gen 2 Type-A port, an SD card reader, and a headphone jack, providing a variety of connectivity options for peripherals and storage devices.


Ergonomics and Design:

  • Curved design: The monitor features a curved 1800R curvature, which can enhance the viewing experience by providing a more immersive feel, particularly for extended viewing sessions.
  • Adjustable stand: The stand allows for tilt, swivel, and height adjustments, enabling you to customize the monitor’s positioning for optimal comfort.
  • Eye care features: Dell incorporates various eye care features like flicker-free technology and a blue light filter to help reduce eye strain during prolonged use.


Performance Considerations:

  • High-end graphics card: To fully utilize the monitor’s 5K resolution and 120Hz refresh rate, a powerful graphics card is recommended, especially for demanding tasks like gaming and high-resolution video editing.
  • Text scaling: Given the high pixel density, adjusting text scaling in your operating system might be necessary to ensure comfortable readability.
  • Potential for burn-in: As with all OLED displays, there’s a slight risk of image burn-in if static elements are displayed for extended periods. However, Dell likely incorporates measures to mitigate this risk.



This new monitor is available now direct from Dell priced at $1,920 USD


Overall, the Dell 5K 40-inch UltraSharp Curved Thunderbolt Hub Monitor (U4025QW) is a technically impressive display ideal for professionals seeking exceptional visuals, smooth performance, and extensive connectivity. However, its potential benefits should be weighed against the requirement for a powerful graphics card and the need for potential adjustments to optimize user experience.
