How do i get this TV to accept my PS3's 1080p output? As of right now that particular resolution is greyed out on my PS3 setup screen. I try to select it but the screen goes black. It is working fine in 1080i but i would like to get the progressive scan working for Blu-Ray and eventually when more games come out in 1080p. Any ideas? Right now i am using a 2m HDMI cable to hook it up and optical for sound. Both monster cable and very good quality.
