Default Resolution isn't the same as in antutu benchmark

I'm using the haipai i9389 and when I use it it has a low screen resolution but in antutu benchmark it says that I have a 720x1280p screen resolution.
I saw in a post that if you change your ROM to one that supports HD resolutions out works but it wasn't for this phone.
Please someone help me I really don't like this screen resolution.
Thanks in advance.
