Lenovo laptop that can't play any games in full widescreen 16:9 aspect?

I have a Lenovo Laptop, it all happens after my laptop was reformatted by the Lenovo Service Centre, to only find out that games like OMSI Bus Simulator can be played in full widescreen 16:9 aspect but others games like Blackshot, Crazy Taxi, Counter Strike & etc can only be played in 4:3 aspect (even after changing their settings also no use).

I even did a full uninstallation of both my AMD & Intel graphic card softwares & reinstalling them again, also still the same.

Graphics card: - AMD Radeon HD 8500M
- Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz

Added (1). I did update both of the AMD & Intel graphic card software to their latest versions. Also doesn't work.
