The dual OLED screens on your Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U are not working correctly – the second screen does not display, both screens show the same image instead of extended desktop, or the touch keyboard on the second screen does not appear. Intel Arc driver updates and Lenovo Yoga Book Companion app restore dual screen functionality on the Yoga Book 9i Gen 9.
This guide covers Intel Arc display driver updates, dual screen configuration, and Yoga Book Companion app setup for the Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U in Windows 11.
“Yoga Book 9i Gen 9 Core Ultra 7 155U second OLED screen was blank after Windows update. Intel Arc driver update from Lenovo Vantage restored both screens. Also needed to reinstall Yoga Book Companion app from Microsoft Store for second screen touch keyboard and note mode to work again.” – Syakirah, UX designer from Bangsar

Why Second Screen Does Not Work on Yoga Book 9i Gen 9
The Lenovo Yoga Book 9i Gen 9 uses a unique dual 13.3-inch 2.8K OLED display configuration where both screens are driven by Intel Arc integrated graphics in the Intel Core Ultra 7 155U. Unlike traditional laptops with one display output, the Yoga Book 9i routes two OLED panels through the Intel Arc display controller, requiring the Lenovo-specific Intel Arc driver configuration that correctly allocates display timing, OLED pixel compensation, and touch digitizer resources for both panels simultaneously. Windows Update can replace this Lenovo-tuned Intel Arc driver with a generic version that does not correctly configure dual-panel output, causing one or both screens to show incorrect display mode or go blank entirely.
- Intel Arc driver generic version not configuring dual OLED panel output correctly
- Windows display mode set to Mirror or single display instead of Extended
- Lenovo Yoga Book Companion app not installed or outdated
- Second screen touch digitizer driver missing after Windows Update

Fix 1 – Update Intel Arc Driver via Lenovo Vantage
Open Lenovo Vantage and run System Update. Install Intel Arc Graphics Driver updates. Restart. After restart, open Settings – System – Display and verify both OLED displays are listed as separate monitors. If only one display appears in Display Settings after driver update, press Windows+P to open the projection sidebar and select Extend. The Lenovo-qualified Intel Arc driver for the Yoga Book 9i Gen 9 Intel Core Ultra 7 155U includes the display panel configuration for both OLEDs including their specific 2.8K resolution, PWM dimming curves, OLED pixel refresh compensation timing, and dual-panel synchronization required for stable display output without tearing or sync issues during dual OLED operation.
Fix 2 – Install Lenovo Yoga Book Companion App
Open Microsoft Store and search Lenovo Yoga Book Companion. Install the latest version. The companion app manages the unique second screen functionality that goes beyond standard Windows display settings: on-screen keyboard mode, trackpad emulation mode, writing pad (e-ink pen and pressure recognition on OLED), and screen orientation profiles. Without the companion app, the second screen functions only as a basic extended display without the specialized input modes that define the Yoga Book 9i Gen 9 user experience. After installing, launch the app and configure the second screen modes according to your preferred workflow between keyboard, trackpad, and note-taking orientations on the Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U dual-screen platform.
Configure Display Settings for Extended Desktop
Go to Settings – System – Display. Both 13.3-inch 2.8K OLED panels should appear as display 1 and display 2. Drag the display icons to match physical orientation (stacked vertically or side by side based on Yoga Book usage mode). Set scale to 150-175 percent for each display for comfortable reading at 2.8K resolution on 13.3-inch panels. Set refresh rate to the highest available option in Advanced display for each panel. Click Apply to save the display arrangement. Moving the taskbar to the preferred panel can be done in Settings – Taskbar – Taskbar behaviors – Show taskbar on all displays and select the preferred primary display for the Start button and system tray on the Lenovo Yoga Book 9i Gen 9.

Fix 3 – Reset Display Controller State
Fully power off the Yoga Book 9i Gen 9 (not restart, not sleep). Close both screens. Press and hold the power button until the laptop fully shuts down. Leave powered off for 30 seconds. Open screens and press power to start. This cold start clears the Intel Arc display controller cached state that can lock one panel into an incorrect configuration after driver update or Windows power event. Cold start allows the BIOS to re-enumerate both OLED panels during POST and allows the Intel Arc driver to perform fresh panel initialization without inheriting the previous session’s display configuration on the Yoga Book 9i Gen 9.
Fix 4 – Update Yoga Book Firmware via Lenovo Vantage
Open Lenovo Vantage – System Update – install firmware updates for the Yoga Book 9i Gen 9. Firmware updates include second screen touch controller calibration data, hinge position sensor firmware for detecting dual-screen orientation modes (book, dual landscape, tent), and OLED panel ICC correction profiles for accurate color matching between both 2.8K panels. Matching color temperature and gamma between both OLED panels requires the OEM ICC calibration firmware that Lenovo Vantage provides specifically for the Yoga Book 9i Gen 9 hardware configuration. Updated firmware also improves second screen keyboard layout detection in different Bluetooth keyboard folio attachment orientations on the dual-OLED Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U platform.
Frequently Asked Questions
How do I set up dual screens on Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U?
Install Lenovo Yoga Book Companion app from Microsoft Store. Update Intel Arc driver via Lenovo Vantage. Settings – Display – arrange both OLED panels as Extended. Set scale 150-175 percent for 2.8K readability.
Why is second screen not working on Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U?
Intel Arc driver update needed (Lenovo Vantage). Press Win+P – Extend mode. Reinstall Yoga Book Companion app from Microsoft Store. Cold restart (power off, 30 seconds, power on) to reset display controller state.
Does Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U have two OLED screens?
Yes – two 13.3-inch 2.8K OLED displays. Second screen acts as extended display, touch keyboard, trackpad, or writing pad depending on Yoga Book Companion app mode and hinge orientation.

Yoga Book Companion app required for touch keyboard, trackpad, and writing pad modes on second screen. Install from Microsoft Store. Without app, second screen only functions as basic extended display.
Conclusion
Lenovo Yoga Book 9i Gen 9 Intel Core Ultra 7 155U dual OLED screen not working in Windows 11 is resolved by updating the Intel Arc display driver via Lenovo Vantage to restore correct dual-panel output configuration. Lenovo Yoga Book Companion app installation from Microsoft Store enables the specialized second screen input modes including touch keyboard, trackpad emulation, and writing pad that are unique to the Yoga Book 9i platform. Windows Display Settings Extended mode configuration and scale adjustment provides comfortable 2.8K dual-panel workspace. Cold restart clears accumulated Intel Arc display controller state that prevents correct dual-panel initialization after driver updates on the Yoga Book 9i Gen 9 dual-OLED platform.
