I have Nvidia msi gt 620 and http://www.geforce.com/hardware/desktop-gpus/geforce-gt-620/specifications it says that my max resolution
is 2048 x 1536 so idk why 900x1300 would be a problem.
yes, your max resolution is 2048x1536, but that does not imply that anything less than that is acceptable. to get an idea of what all video modes your video card supports do the following (assuming Windows 10 but other versions of Windows should be similar):
1 - Right Click your desktop and choose "Display settings"
2 - Click "Advanced display settings" at the bottom of the new window
3 - Now in this window you will see a drop down box titled "Resolution"
4 - This drop down box contains all the resolutions supported by your video card
I am sure they is probably a quicker way to get this information but I dont hack around in Windows too much.
