Not able to get full resolution

[gradlius]

Hi everyone ,

My Pc:
Gigabyte Z68AP-D3 Z68 Bios F3
Intel Corei5-2500k
CORSAIR 8GB (2x4GB) Vengeance DDR3 1600MHz CL9
CORSAIR 60GB Force 3 GT
OCZ 60GB Agility

I installed Maverics with Clover Bootloader on my desktop pc.Everything perfect except screen resolution.(I got only 1280x1024)
How can i get the right resolution (1920x1080) on my desktop ?
(I dont use my xfx hd6850 I used my i5's gpu )

Thank you.

Use Chameleon Wizard and select the resolution you want ?

I used it before I ran the wizard select the resolution but nothing changed. I am not sure did it right or wrong.Just click and install or anything else ?

(Any Chameleon Guide you suggested)
Thanks.
