DR Jose i tried that.
Actually i think i may have found an answer. Although i'm not sure i completely understand it.
I found this question (which is my question):
I have a 22 wide screen monitor. Is there a simple way of viewing my pictures normally (not stretched) without opening them in any of the photoediting softwares. Thanks.
And this answer:
A usual widescreen monitor's aspect ratio is 16:9.
Therefore, you have to change your display resolution to something in line with 16:9 such as 1600x900. 1280x768, 1360x768 or 1280x800 might also do.
If you are using a Windows OS, you can change resolution by right-clicking a blank space on your desktop then left-click properties to go to Display Control Panel. A window will load and click the Settings tab found above. In settings, you can see screen resolution. Choose desired resolution and finalize it by clicking OK.
