Hello, I got a Chinese Google TV box called A6 HD-HYNUDAL and it comes with RK2918 chip. The problem is when I tried to set the output to HDMI, the screen became black and I had to reset the device. Anyway, when I looked at the options it turned out that the box only output @ 1080p. The problem is that my TV only support 720p. I searched here and found that some of these TV boxes support 720p. my question is; is there a way to make my box output at 720p?
