Laptop External Monitor Issue

I finally got around to getting an external monitor so i could play and watch minecraft at the same time. However, when I set it to extend display, minecraft is unplayable on the external monitor. It only has VGA and DVI, so i used an HDMI-DVI cord from my laptop to the monitor. Minecraft loads up perfectly fine, but once I get in game, the fps drops way low and it seems as though the sensitivity is crazy high (even setting it to 1% didn't make a difference). The confusing this is that everything else I have tried works on the second screen, such as internet browser and steam games. I have done multiple Google searches into this and have come up with nothing. Also worth note is that when I tried it on a different laptop it worked perfectly fine, so it seems to be a problem with my computer. Anyway, here are the specs, Any help is appreciated.


Please help.

Thanks!



I didn't find the right solution from the Internet.
