Yes, you can adjust the display settings for CS:GO to fit different windows. For windowed mode, you can change the aspect ratio to 4:3 and ensure the window is set to fullscreen. If you need guidance, look for a tutorial on adjusting display settings in your game client or operating system.
It's likely the same issue as changing the refresh rate in windowed mode.
You confirmed your CS:GO settings are already available in-game. You can choose 4:3, 16:9, or 16:10 within the windowed view. No need to adjust the Nvidia control panel.
I understand the issue was adjusting the display settings. It didn’t fit the entire screen unless it was in fullscreen mode. If I changed the settings in NVIDIA Control Panel, my CSGO view would shift to fullscreen, which might be what you were trying to achieve. It’s a bit confusing, but I think you got the point across.
