Make sure your drivers are setup for stretched.  Set perform scaling on GPU & fullscreen. Here's how with nvidia https://imgur.com/a/QOXTUKl

For AMD, you need Custom Resolution Utility.  Can be found here: https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU https://imgur.com/a/J7IAhGJ

Click on add, underlined in pink, then set the width resolutions, make one for 1440x1080, 1350x1080, 1280x1080 for 1080p monitors, or make 1920x1440, 1800x1440, 1600x1440 for 2k monitors, or whatever resolutions you desire.  Make sure to set them as 120hz/144hz at the bottom.  Then you must restart your computer.

These aliases scale m_yaw so it's 1:1 movement, even when stretched.  Without scaling m_yaw with stretched, a circle on your mousepad will make an oval in game.  Make sure remove m_yaw from your autoexec to not interfere.

To find correct scaling for m_yaw for different resolutions, use this equation, (1024/768)/(16/9)*0.022, replacing 1024 and 768 with your height and width.  Or use wolframalpha https://www.wolframalpha.com/input/?i=(1920%2F1080)%2F(16%2F9)*0.022

x1080 or x1440, native width resolutions, will much have less distortion, but **will not work without making custom resolutions**.
The standard 4:3 ratio aliases will work.  Use the command mat_info to make sure the game is running at the right resolution.  The game sometimes reverts resolutions.
