I have tried to find a solution to my problem through google, but have not found any, just similar cases which were not suitable for my problem.
So, I have ultrabook with Windows 7 (Intel HD 4000 / nVidia GT 620m). I installed some old games with low resolution (620x480; 800x600 ...) and it worked fine - system kept aspect ratio and created black bars when needed, so game looked normal. About a week ago for some to me unknown reason it began to change it. Every game is widened now and looks "fat". Even when I change resolution and settings in game that allows it, the screen is widened anyway. My graphic control systems seem to be "cut" - they dont have any option to "keep aspect ration" or so. control panel neither. I did not instal any updates or new drivers
, so I do not know what exactly happen. Any clues would be really appreciated.
