Dell has issued a firmware update for its Alienware AW3926QW monitor that adds a control panel switch to turn off CPC, an OLED protection feature built into LG displays. CPC artificially dims the screen's edges to reduce burn-in risk.

Why it matters

CPC edge-dimming caused brightness and color uniformity issues that affected video and photo editing work, and the monitor previously offered no way to disable it. The update gives users control over a tradeoff between display consistency and burn-in protection.

The AW3926QW is a 39-inch 5120 x 2160 monitor with a 165Hz refresh rate and a WOLED panel, costing over $1,000 at MSRP. CPC is triggered only when motion is detected, and the update does not indicate how burn-in risk changes once it is switched off.

The players

Dell

Dell is a major American computer hardware company that markets the Alienware gaming line of monitors and PCs.

LG Display is a South Korean manufacturer whose OLED panels, including the WOLED type used in the AW3926QW, include the CPC protection feature.

The details

The firmware update adds a switch in the monitor's control panel that turns off CPC, which dims areas such as in-game HUD elements, the Windows taskbar, and title bars. Users who disable it can offset the risk by keeping other OLED safety mechanisms enabled and running the display at lower brightness.

A few months before November 5, 2026: Dell announced it would investigate the CPC edge-dimming problem.
November 5, 2026: Dell's firmware update adding the CPC toggle was reported.

The Tech Race

The fix reflects an ongoing tradeoff in OLED monitors between burn-in protection and uniform image quality, a balance LG built into its WOLED panels. Dell's toggle shows how display makers are now giving users control over that tradeoff on premium gaming hardware.

Owners of the AW3926QW can now turn off CPC in the control panel, which may restore uniform brightness for photo and video editing. Disabling it means relying on lower brightness and other OLED protections to limit burn-in risk.

The takeaway

Owners of OLED monitors should weigh edge-dimming against burn-in risk and consider lowering brightness if they turn the feature off. Checking for firmware updates on premium monitors can add controls that were not available at launch.
