Reshade not fitting the whole screen

Hey everyone! I  was wondering if you might be able to help me with a new found issue I encountered. I've been using Reshade for a few years and never had any problems. But with a few rare games like The Witcher 3, reshade gives me this weird black and sometimes very bright outline around the screen. I did some digging and found out that it's because I usually play in a 2715x1527 resolution, but reshade resolution for some reason is at 2700x1500, the reshade it's not fitting the whole screen and I don't know how to fix this.
Would you be so kind to help me solve this issue? Thanks

Hello! maybe the problem is similar to the one I had. You have to go to the location where Reshade is located. where “Reshade.ini” is located where [OVERLAY] is located and where “Docking=” “Window=” is located you have to put your resolution where “Size=” and “SizeRef” are located [sorry if my English is bad, I'm not a native speaker].
