I don't actually have an HID but I know a bit about them from playing with HID scuba diving lights. The pattern from a headlight depends partially on the distance the light source is from the reflector... change that distance and you change the angles the reflector works at, which changes the way the lens works. I'd bet the HID "bulb" has its light source at a different height to the standard H3 bulb.
Point your bike (upright, with someone sitting on it) at a wall and check the height the main "spot" sits at and its shape, then compare it to a friends' standard headlight (or replace your HID with an H3 for the test).
Something else just occurred to me... you're in South East Asia and they get things from all over the world there... you may even find it's not the HID at all, you may have a lens from the wrong part of the world (ie: for driving on the other side of the road). It's worth checking...
