Re: Sims stuck in windowed mode

I just got a new gaming monitor I got a aoc gaming 34in and I got a cyber power pc desktop now the picture in sims is good the words are a little lower resolution than id like . So I went to sweating to make it higher resolution 3440x1440 and it gave the the black bars on the side why is that ? How can I stay full screen with that resolution and yes it is on full screen
