Wrong Windows 8 RTM Bootscreen Resolution

I'm using Windows 8 RTM build 9200 from Dreamspark. The Windows is very good but i have a small trouble with it. When i install Windows 8 without UEFI supported ( I setup from USB with NTFS format so as i know, UEFI cannot be enabled when we install from NTFS drive ), the bootscreen is normal. But when i change to setup with NTFS supported ( enable UEFI in BIOS setting, change hard drive to GPT, make setup from an USB with FAT32 format ), the bootscreen is in wrong resolution. It's stretched so looks like longer, although during last steps of installation, it still show the right resolution. I dont know how to fix this. Please help me
