Cannot detect wide screen

[LG34UC99]

Hi there, can anyone advise why my HP laptop cannot detect my widescreen? On Sony laptop with windows 8, it can detect the widescreen and automatically change the resolution from 1920 x 1080 to 3440 x 1440. It looks like it may be a driver problem. I google and they say I can try roll back the driver. But the laptop do not allow the roll back function.

Any advice or comments will be most helpful. Thanks in advance!
