I am trying to switch my xbox 360 slim to 1080i since my tv is only 480p and 1080i but there isn't an option at all like in the older xbox 360 consoles has anyone gotten around this? Is there something I am missing?

You need to have a component or HDMI cable. Are you using one?

yes I am using a DVI to HDMI cable but when i try to set the resolution to 1920x1080 the screen turns black and gray I think this is because the xbox is set to 1080p not 1080i

thanks for the quick reply

Does it give you the option for 1080i in the resolution settings? I haven't used a DVI/HDMI cable, but my HDMI setup gives me the option for both 1080p and 1080i.

That is exactly what I mean my xbox won't give me an option to pick either 1080i or 1080p just 1920x1080, is your'e xbox a slim model?

Yes, but the interface is identical for all versions. I wonder if it's because you have a HDMI/DVI cable. It's possible that the DVI settings don't support 1080i as DVI is generally used with LCD monitors.

If your TV can do 1080i, I would think it would be able to do 720p. (That is, unless your TV is really obscure and has an odd setup.) You might try 720p/1280x720 and see if that works.

the highest it goes is 848x480 DVI i guess what I am going to get are RGB cables since my tv won't display 1080i through DVI

try disabling auto detect display?
