CSGO and Monitor issues? Please read!

[YourPanda]

Hi, so I am trying to play CSGO, however I have a 17in monitor, and a 23in monitor. Well, what my issue is, when I make my 23 in monitor the main monitor, and completely remove my 17 in monitor, CSGO is not 100% full screen, on the left and right side there are two black columns. And, these columns are here even when I have my 17 in monitor connected. Here is what I am talking about.

How can I get rid of those back columns on either side so that I can play CSGO on the full 23 inches and not 17 inches of it?


Also, how can I make my second monitor (The 23 inch one) the one that has CSGO on it, and still have my first monitor (the 17 inch one) still working, and so fourth?

I use an AMD radeon graphics card.. Please let me know how I can make this work for me, as it is annoying as hell.. And, I do not know how to fix this..


This is my 17 in monitor, and all is well on it... However, my 23 in is thinking it is a 17 in monitor, and only puts 17in of the screen up.. This from what I have seen so far, only happens with steam games... For MC I can full screen it, and everything, and it works just fine.. But, for CSGO, it does not work at all..

change ur screen resolution
!?!?!?

I have it at the defaults. I have done legit everything.. Nothing has worked.

Don't make it the default then.

The default ones are the max you can go.

In CS:GO, what options to do have regarding resolutions?
Does it say something like "Windowless" ?
