Hi everyone,
I'm running a dual-boot setup with Windows and Ubuntu 20.04 on my PC. My graphics card supports a 1600x900 (16:9) resolution, which works perfectly on Windows. However, on Ubuntu, I only have three resolution options: 800x600 (4:3), 848x480 (16:9), and 1024x768 (4:3). Unfortunately, none of these options match my monitor's native resolution.
Is there a way to enable 1600x900 (16:9) resolution in Ubuntu 20.04? Any help or guidance would be greatly appreciated!


P.S. I’m also using a dual-monitor setup. The integrated graphics card is connected to one monitor, while the installed dedicated graphics card is connected to the other.


Do I need to provide any additional information to help resolve this issue? If so, please let me know, and kindly provide me with step-by-step instructions on how to gather that data using terminal commands.
Thanks in advance!
