My apologies should this problem already have been discussed, also please excuse my less than perfect English.
I have used Screenshot Captor for quite a while, exclusively for screenshots of games in full screen mode, ie no windows here.
That worked just fine until I bought a new monitor. The new resolution is 1920x1078 which leads to a ratio of 16:9.
The old one was regular 4:3 stuff (maybe 5:4, I'm not sure.)
The images used to have the size of 1280x1024 which was the right  ratio.
Now I would assume that Screenshot Captor recognizes the resoution of 1920x1078 and produces images with that ratio. Which seems not to be the case. The images still have the format of 1280x1024, a distortion is the consequence.
I did not find anything in the preferences where I possibly could do something to tell SC what it is supposed to do - ratiowise.

I tried capturing Screen and whole workspace (no idea anyway what the difference might be), results were just the same.
Any ideas anybody? Any help would be appreciated.
