What changed
TFTCentral announced on November 5 that the new firmware offers a switch to control the edge-dimming / CPC OLED care feature. VideoCardz reports that the firmware is available through Dell's support website. TFTCentral said it would test and validate the change "very soon."
Before this release, the monitor had no way to turn CPC off. The September reporting from VideoCardz said the feature was enabled without any user control on the AW3926QW.
The sources reviewed do not give a firmware version number or a full change log for the new release. They also don't give the exact menu path for the new CPC toggle. Check the AW3926QW's own listing on Dell's Drivers & Downloads page for the current package.
What CPC does
Dell's support article for the AW3926QW and AW3226Q describes the symptoms as edge or corner dimming, color shift, green tint and uneven color or luminance uniformity. Dell says the brightness reduction is an expected result of the Constant Power Control (CPC) protection mechanism. Dell describes CPC as a feature that darkens the outer edges of the display to reduce the risk of burn-in.
Dell's article points to two workarounds. Brightness gradually recovers after you switch to uniform content. Raising the brightness setting may also narrow the gap between the center and the edges.
TweakTown and VideoCardz expand the name as Convex Power Control. Dell's own page says Constant Power Control. I'm following Dell's wording and noting that the two outlets differ.
TweakTown says CPC is triggered only when motion is detected. It lists areas such as game HUD elements, the Windows taskbar and title bars as the places most vulnerable to burn-in. That is TweakTown's description, not Dell's.
Dell also says some brightness variation is a known trait of the 3-sub 4-stack OLED panel type and is not a defect. So CPC is one stated cause, and some panel-level variation remains on top of it.
Caveats before you flip the switch
- Independent testing is pending. Independent testing is still needed to determine how much the toggle improves uniformity. TweakTown's claim that the toggle "completely" fixes the problem goes further than the evidence so far.
- Burn-in risk. Disabling CPC may also reduce protection against image retention. None of the sources I reviewed quantifies that risk.
- Warranty is unanswered. In September, Guru3D noted that whether disabling CPC would affect burn-in warranty coverage remains unanswered. The new reporting doesn't resolve it. Read Dell's warranty terms before you disable it.
- Mitigation is general advice, not Dell guidance. TweakTown suggests leaving other OLED safety features on and running at lower brightness. That is a reasonable precaution, but Dell hasn't presented it as a substitute for CPC.
Creators and photo editors have the clearest reason to want the switch, since vignetting can skew judgments about color and brightness. People who leave static Windows UI on screen all day have the strongest reason to keep CPC on.
How to install the update
Dell's general monitor-firmware guide is not specific to this release. It says you can use Dell Display and Peripheral Manager (DDPM) or a downloaded package.
Before you start:
- In the monitor's on-screen menu, turn DDC/CI on.
- Connect the monitor's USB upstream cable directly to your PC, not through a dock or hub. For this model, TFTCentral says you just need the screen connected via USB A > B from PC to monitor. That quote comes from its August firmware article.
- Update one monitor at a time. Turn off sleep mode on the PC and the monitor.
Using DDPM on Windows:
- Open DDPM from the system tray or Start menu.
- Select Settings (the gear icon).
- If an update shows for your monitor, select Download and install.
- Don't unplug the USB cable or power off the monitor during the update.
Dell's guide lists Windows 11 and Windows 10 (build 17763 or newer) as supported. Windows 11 ARM devices with Snapdragon X-Elite or X-Plus chips are supported from DDPM 2.3.2.
Manual install:
- Disconnect the video cables and any extra USB cables, leaving the monitor powered on.
- On Dell's Drivers & Downloads page, find the monitor by Service Tag or model number.
- Choose your operating system and the Application category.
- Download the Firmware Update Utility, run the .exe and select Update.
Expect the update to take roughly 10 to 30 minutes. The screen may go briefly blank, and the monitor restarts by itself.
If it fails:
- Don't force a power-off. Give it the full time window first.
- Try running the utility as administrator.
- Use a direct USB connection and confirm DDC/CI is on.
- If you see "The selected firmware is not for this monitor," you downloaded the wrong file.
To check your firmware version afterward, use DDPM's Settings page or the monitor's menu. Dell says the menu location is typically under Menu > Others or Menu > Personalize, depending on the model.
What this is not
This is not the August M2B102 firmware. TFTCentral reported that the update was released on 26 August 2026 and that it fixed the sRGB gamma curve in Creator > sRGB mode. In TFTCentral's testing, it didn't change CPC edge-dimming behavior.
The AW3226Q
TFTCentral reports that Alienware is preparing a similar update for the 32-inch AW3226Q, possibly as early as next week, with no confirmed date. Nothing in the sources shows it has shipped, so AW3226Q owners should wait for an official release.
Takeaway
The release is a good sign. Alienware said in September that it wanted to understand the "full customer experience implications" before enabling a toggle, and it has now shipped one. The open questions are how much the toggle improves uniformity, what it costs in burn-in protection, and whether disabling CPC affects warranty coverage. If edge dimming bothers you, the update is worth installing, but wait for TFTCentral's measurements and Dell's warranty position before you leave CPC off permanently.
