Dell is testing a firmware toggle to disable Convex Power Control on the Alienware AW3926QW, addressing the 40% brightness drop at screen edges reported by testers.

Dell is testing a firmware toggle to disable the Convex Power Control (CPC) feature on the Alienware AW3926QW OLED monitor. This change matters to buyers because the current implementation causes significant brightness unevenness across the screen. Users who value consistent image quality will benefit from a potential fix that removes the artificial dimming at the edges.

Dell addresses OLED edge dimming with firmware toggle

The Alienware AW3926QW is a 39-inch OLED display designed for high-end PC gaming. It features a 5120 x 2160 resolution and supports a 165Hz refresh rate at that resolution. The panel also offers a 330Hz refresh rate when running at a lower 2560 x 1080 resolution. This dual-mode capability allows users to choose between higher resolution or higher frame rates depending on their needs.

Specifications

  • Panel Type: OLED
  • Resolution: 5120 x 2160
  • Refresh Rate: 165Hz / 330Hz
  • Price: $1,099.99

The core issue stems from the CPC feature, which Dell implemented to prevent OLED burn-in. This technology artificially dims the luminance around the edges of the display compared to the center. Independent testing by TFT Central revealed that this dimming causes a 40% lower luminance at the screen edges. The result is a noticeable drop in brightness uniformity that affects the overall viewing experience.

Dell addressed the feedback directly in a statement regarding the uniformity issues. The company said, "We hear the feedback on uniformity and are actively testing a potential toggle that could give customers more control over uniformity. We want to make sure we understand the full customer experience implications before we enable anything. More to come soon." The monitor currently retails for $1,099.99 USD (around $1,100).

We looked at the last Alienware AW3926QW update while tracking similar balance and stability themes in OLED displays. The CPC toggle remains in the testing phase and is not yet available to customers. Dell plans to release the feature only after fully evaluating its impact on the user experience.
