How to Fix a Flickering Text Cursor on the Asus Zenbook Duo Secondary Screen

Product: Microsoft Word / Text Editors
Device & OS: Asus Zenbook Duo (Windows)
Scenario: Typing or editing text documents in Microsoft Word or other text editors while the application is positioned on the lower secondary display.
Observed behavior: The text cursor becomes excessively bright or flashes erratically, causing visual discomfort and disrupting the typing workflow on the second screen.

Before you start

Ensure your Asus Zenbook Duo is plugged into a power source and that you have saved all open documents before updating display drivers or modifying registry settings.

Update Graphics Drivers and Display Settings

Updating your display drivers and standardizing the resolution across both monitors is the most common fix for secondary screen rendering issues.

The dual-screen architecture of the Zenbook Duo relies heavily on optimized graphics drivers. A mismatch in resolution scaling or outdated drivers can cause text cursor rendering glitches on the lower screen.

Update the Graphics Driver

Right-click the Start button and select 'Device Manager'. Expand the 'Display adapters' category, right-click your primary graphics card (e.g., Intel or NVIDIA), and select 'Update driver'. Choose to search automatically for updated driver software.

Adjust Display Resolution

Right-click on an empty space on your desktop and select 'Display settings'. Click on the display representing your lower monitor.

Apply Recommended Settings

Scroll down to the 'Scale and layout' section. Ensure that both the 'Display resolution' and 'Scale' dropdowns are set to the values marked as '(Recommended)'.

Restart the Device

Restart your Asus Zenbook Duo to apply the graphics updates and check if the cursor flickering persists in your text editor.

Update Graphics Drivers and Display Settings

Testing Single Display Mode: As a diagnostic step, try pressing Win + P and selecting 'Second screen only' to see if the cursor still flickers when the lower screen is acting as the sole display.

Solution 2

Disable Office Hardware Graphics Acceleration

Use this method if the flickering only happens inside Microsoft Office applications like Word, as hardware acceleration can sometimes conflict with dual-screen laptops.

Frequently Asked Questions

Why does the text cursor only flicker on the lower screen of my Asus Zenbook Duo?

The lower screen (ScreenPad Plus) uses a different display matrix and often interacts differently with your laptop's integrated and discrete graphics processing units. Software rendering bugs or mismatched DPI scaling settings between the primary and secondary displays often manifest as flickering elements, like text cursors, when a window is moved to the lower screen.

Does disabling hardware acceleration affect my laptop's performance?

Disabling hardware acceleration shifts the UI and text rendering workload from your graphics card (GPU) to your main processor (CPU). While it effectively bypasses GPU-related flickering bugs, you might notice slightly slower performance or reduced smoothness when scrolling through heavily graphic-intensive documents or large spreadsheets.

Can a Windows or Asus firmware update fix the cursor brightness issue?

Yes. Asus and Microsoft frequently release patches specifically targeted at dual-screen optimizations and display anomalies. Regularly checking the 'MyASUS' app for BIOS/firmware updates and navigating to Settings > Update & Security > Windows Update can often permanently resolve underlying display glitches.
