1080i and 60Hz help.

[Arik5405]

I have a 1080i tv I want to use with my HTPC. I am having a problem getting it to go to 1080i 60Hz. It will do 1920x1080 at 29 and 30Hz but it has a noticeable "vibration" to it. It will do 720p at 60Hz no problem and looks great. But I would like to throw a blueray drive in the HTPC in the near future and watch it at 1080. The sticker on the back of the tv says 1080i and underneath that says 60Hz. Now, that 60Hz isn't directly next to the 1080i, so did the tv company (mitsubishi) slip a curveball by me? Yes it will do 1080, yes it will do 60Hz, just not at the sametime! Another thing, is 1080i only 30Hz and 1080p 60Hz? If so, how come I don't have any problems playing the Xbox 360 at 1080i? Wouldn't there be some sort of "vibrations" for that too? Both the HTPC and 360 are hooked up via HDMI.

The specs of the HTPC are:
E6600
HD4850
4gb DDR2
bla bla bla....

Thanks for the help!

1080i is 30Hz. I don't know exactly what you mean by vibration but maybe you're talking about how it's not as smooth? 60 will be smoother than 30 if that's what you're asking. That's why when things are moving fast you want a progressive picture cus it'll refresh faster and be able to provide a smoother picture. The i on the 1080 will be half as fast and won't be able to provide as smooth as a picture as the p or progressive picture will which is why the 720p looks smoother during certain situations. Only a 1080p set to do 60Hz @ 1080. The 60 on the back of your tv refers to the 720p you have. Just run 720p and be done with it. 1080i will look great on slow moving things but once action pics up and lots of stuff moves on screen, the 720p will shine.

gotcha, that's what i figured. the tv is about 3 years old now so that's pretty much the answer i was expecting. My 42" is a 1080p and thats why it has no problem running 60Hz. Thanks for the reply.
