Issue Details

I reinstalled the operating system (OS) of my PXI controller but I found the video output resolution is only 1400*1050, normally 2560*1440. How to fix it?


After reinstalling the OS, you have to install Peripheral Drivers for Controller based on the type of your controller.

For example: PXIe-8881 Firmware and Additional Drivers

You also can update graphic card driver manually by using Device Manager in Windows

Additional Information

Kindly ensure the monitor you are using is compatible with the resolution you are planning to implement else the monitor will be the factor that affect your video display resolution.
