Can't put screen resolution higher than 1280-1024 on new boot drive

So recently I bought a new SSD (Samsung EVO 850 250gb) for my computer to boot from. I installed Windows 7 Home Premium 64-bits on it (The same installed on my old HDD boot drive).
But when I boot from my new SSD, windows looks more pixelated and different than when I boot from my HDD. There's two main problems:
1. I can't put the screen resolution higher than 1280-1024 via windows. (While on my HDD I can set the screen resolution to 1920-1080)
2. Windows transparent theme won't work. I have tried to turn it on, and read multiple forums about it, but for some reason when I try to change it, it says my graphics card (Geforce GTX 770) can't support transparent theme, which is weird considering it does work when I boot from my HDD.

My monitor is an LG LED 22m45.

If anybody has got any idea why this might be so, or how to fix it, please reply.

Ps. I am not too handy with computer, so please try and explain it in a simplistic way if possible.

Thank you in advance.

    It sounds to me as if you did not install the drivers specific to your video card on the new instance of Windows.
