I have found a solution for myself finally. Luckily my GTX 660 has 1920x1080 already so I don't have to edit VBIOS. The problem was the black border still appears around my monitor during boot. It means I have native resolution but under scanned. After Google research I found that my motherboard bios was set to stretched mode, to switch to centred mode, you will have to go to level 2 of solution of the following page: http://www.tonymacx86.com/graphics/121519-nvidia-how-get-rid-black-border.html
As the original post mentioned in level 2 ( don't hurt me ), you need to download author's boot0 file.
I have no idea how to do with antonio765's ( the author of TonyMacx86's link ) method (The command "sudo dd if=boot0 of=/dev/diskX bs=440 count=1" gave me permission denied ) but his boot0 file has fixed my black border problem. Thanks to him anyway
If you have followed the steps of antonio765's post, then you should have full screen bootloader without black border like my video: http://youtu.be/1uz-RzxMUyA
Check out my new video to solve the black border problem:

PS1: If you use this command sudo dd if=boot0 of=/dev/diskX bs=440 count=1 and received "permission denied", then try this one fdisk -f boot0 -u -y /dev/rdisk0
PS2: I have experienced black border would appear again if you change bootloader themes. To solve this issue, just install the boot0 to your drive again after applying new theme.
PS3: HDMI works with this solution or antonio765's solution, I'm using it until now. Let me know if this works for DVI.

As the original post mentioned in level 2 ( don't hurt me ), you need to download author's boot0 file.
After getting boot0 from the download link in the post, you will have to launch Terminal.app to install the file to system.Type sudo -s and then your password. In my case, I use "fdisk -f boot0 -u -y /dev/rdisk0" ( Click here for more information ) instead of using the author's "sudo dd if=boot0 of=/dev/diskX bs=440 count=1" ( Click here for more information ).The idea of this solution is just to call bios function which will switch video card from stretched to Centered mode:Code:mov ax,4F14h ;VESA VBE OEM function mov bl,2 ;Subfunction 02 = Set Panel Expansion/Centering mov bh,1 ;00 = Return Current Setting, 01 = Set Centering/Expansion mov cx,0001h ;Exp. mode: 00 = Scaled, 01 = Centered 1:1, 02 = Left Corner 1:1 int 10h ;call VGA/VBE service
