Cannot change resolution to optimal on external monitor

[LinkRyder]

I have a lg w2243s, not the PF model, and it does not have a driver for Win7, despite that it works fine on my old laptop, which also has Win7 installed, I can use the maximum resolution, no problem.

On my newer laptop, ASUS with both integrated (intel hd graphics 3000) and dedicated (nvidia 520m) it only allows me two resoltions 800x600 and 1024x768, despite the optimal one being 1920x1080.
I have the latest drivers installed for graphic cards.
Please help.Thanks.
