Some games cannot go fullscreen

[JakubDabrowski]

Hello,

Thank you for contacting us on the forum.

I have few questions to clarify this case even more.

1. Did you test other games in fullscreen or only CS:GO? If not, please verify that.
2. What resolution are you using in CS:GO? It seems like your monitor should be working in Full HD. Please also check other resolutions if they impact the screen in any way.

Thank you for your feedback.

Best regards,
Jakub
