Issue with extending window of an app across two side-by-side monitors

Question

Hello, I have three monitors as below image. Display 1 is my labtop and displays 2 and 3 are two identical monitors side by side. I have VS code application. I would like to extend the window of VS code so that I covers monitors 2 and 3 completely. This way I have lots of space for coding purpose. My laptop is extending its disply to Monitors 2 and 3 via USB-C cable. Monitor 2 has can be set to max resolution 2560x1440 and monitor 2 the hight reolution available in the drop down list is 1280x800. To have the app span accross monitors 2 and 3, I have to reduce the display resolution of Monitor 2 to 1280x800 to match the 3rd one. Is this an hardware issue with my laptop?

These are the specifications of my laptop.

Answer 1

Hi c s, Thanks for your post. Can I know if the Monitor 2 and 3 same size? Generally speaking, if you see unexpected changes in your screen resolution, your graphics driver might need to be updated. To see and install available updates, select Start >Settings > Update & Security > Windows Update. Reference: Change your screen resolution in Windows - Microsoft Support

Best Regards,
