Okay, did you follow the tutorial that I linked to exactly in my previous post? It offers a step by step guide on how to fill up your specifications.
Anyway, based on the preliminary data you've filled up and your Laptop model, it seems like it's using an AMD Graphics Chipset...and it has a native screen resolution of 1366x768
Have you tried checking whether your Desktop Resolution matches the native resolution of your screen?
1. Right click on your Desktop
2. Click on Screen Resolution
3. In the next panel, select the dropdown box next to Resolution and select 1366 x 768
4. Click Apply, then OK.
