Do i need to drill the mounts into the wall studs or can the drywall sturdily hold it?

the monitor weighs just under 10lbs. http://www.bhphotovideo.com/c/product/1044623-REG/benq_gw2760hs_27_led_glossy.html
if just mounting to drywall then don't use hole plus to screw into but use what I think are called butterfly clips that are 2 spring mounted wings that spread out on the other side of the drywall when tightening the screws.
