Poor Lightroom 4.4 performance when laptop connected to an external monitor

Hello everyone,

I have recently purchased an external monitor to be able to view my photos at a higher resolution (1920*1080). However, Lightroom performance is extremely bad and the sliders are laggy when I just use the monitor that I have bought. Doing the same task on my laptop monitor takes much less time and runs perfectly smooth (the resolution of the laptop is 1366*768).

Is this an issue with Lightroom 4.4 or is it my because my laptop is not fast enough? 
Any helps would be appreciated!
