cant select 1080i (1 Viewer)

[daewoomofo]

hello to all, i hope ive posted this in the correct area, if i havent im sorry.

well heres the deal
i have a magnavox nb500ms9 blu-ray player connected to my onkyo ht-667 via hdmi to hdmi. it goes from the 667 to my sharp xr-30x projector through a hdmi to dvi cable. the projector is capable of 1080i. iv had it at 1080i with my wow cable box so i know its able to do the 1080i. with the blu-ray player you can select the resolution that it outputs, it has 480p, 720p, 1080i, 1080p, and 1080p24. since my projector cant do 1080p i would like to get 1080i, but when i have the blu-ray connected to the receiver ,1080i is not selectable, but 1080p is along with 480p and 720p. when i connect the blu-ray directly to the projector with the same hdmi to dvi cable i can select 1080i along with all of the others. ive tried changing all of the hdmi settings on the receiver, but i still cant get video to my projector, i get audio on the receiver but that does me no good with out video. the odd thing is that as i said ive had it at 1080i with my cable box running through the receiver. does any one have any ideas about what is the problem here? id really like to be able to watch blu-rays in 1080i instead of just 720p. thank you all in advance for any advice you can give me!


if any one is looking for stats on the onkyo its part of the ht-s6100 theater in a box.

Your projector can't "do" 1080i. 1) It is DLP and therefore incapable of displaying an interlaced image and 2) Its native resolution 1024 x 768, so it is effectively a 720p (768p) unit. It can accept a 1080i signal, but so can can every HDTV. Regardless of the input, the TV is going to rescale it to 768p. Even if you could send it an interlaced signal, the TV would just have to deinterlace it and then rescale it. That's just extra processing for no increase in actual resolution. You are probably much better off using the 720p setting in any event.
