to all sifus here, please help me..

recently i bought a new LED TV, Samsung UA40D5030..

when i connect my ps3 to this TV via HDMI cable, it only can output 576p only. whenever i choose 726p/1080i/1080p, the screen will go blank and then back to this 576p

already tried with the resetting with power button off-->then keep pressing until beep..

the same ps3 and cable on my samsung LED monitor is working fine in 1080p

is it could be the cable problem? i'm using a cheap HDMI cable

any solution?
