There are three different drivers that you could use in your system.
The most recommended is the OEM driver, this is to avoid loosing any special features or settings added by your OEM that would not be available while using other drivers.
With that said, here you can find the 3 drivers you can use to test your system:
1. OEM version: Version V22.214.171.12400 // https://www.asus.com/Notebooks/ASUS-ZenBook-UX305UA/HelpDesk_Download/ please select OS and look for VGA driver.
2. Intel® generic drivers: A. Download Intel® Beta Graphics Driver for Windows® 7/8.1/10* [15.40] 4380
3. Generic drivers from Windows 10*, you can get them by uninstalling the current driver from device manager and letting Windows 10* install the defalt after rebooting your system.
I look forward to your outcome with this.
