Hey I'm new so I might be in the wrong place. There have been some questions that need answering and this looks like the best place.

A couple of years ago I bought a 52" Akai HDTV projection. It was only $1200. This is why it seems a bit fishy. Supposedly it supports 1080i. I read that this is the highest of the HDTV displays. On the back of the TV, it has component ports for 480/480, and 480/1080. That's how it reads. I bought some $80 cables for an Xbox, and plugged them into the 1080i side. They turned the screen black and white. I plugged them into the 480 side. The picture stayed black. When I bought the cables, I also saw that they said 1080i on them, which leads me to believe they don't support 480. But, like I said, I really don't know much about HD.

I guess the real question here is that I wonder if my TV actually supports HDTV and the cables were screwed up, or if I had this coming by buying a cheap HDTV. Also, is there anyway to test the HD part of the TV without buying a reciever and all that jazz?

Also, another thing is that I tried the same cables upstairs on a TV that says nothing about being Hi-Def. However, it has component cables on the back leading me to believe it does support 480....(thats progressive scan right)?

And finally, if you can handle all of that, I had a general question about HDTV. Why is it that a 52" projection RCA HDTV that is Hi-Def ready, cost $800 less than a 51" projection Sony HDTV that has a built in DCR. A DCR by itself only costs about $200.

Thanks a lot for all your answers in advance.

Now I think maybe I should have posted this message in the gaming forum. Only I did, and it was modded. (I know, no double posting. I figured this one would've been the one to go). I doubt I'll get an answer in here. Is there any way to delete this topic so I can post it in the other forum?

Did you enable the 480p, 720p and 1080i settings in the XBOX dashboard as well as the 16:9 Widescreen mode (if your TV supports it)?

Yes. Before enabling 1080i, the picture was distorted. Top half of screen on bottem half and vice versa. After enabling, it turned the made the picture right with the exception of the black and white color.

<--- Sigh. Some other things to add. First of all...this might be rear-projection, but like I said before, it's too late to change to another forum or I'll get modded. Sorry, I don't know crap about T.V.s

But another thing that might be useful....Under the 480i/1080i section of the component jacks, the video side is listed Y,Pr,Pb, whereas the cables were listed as Y,Cr,Cb....

Should I just try to get a new T.V.? Did I screw up buying a 52" HDTV for $1200 at Sam's Club?

Ok thanks. I understand what you're saying. It's just strange that the cables I bought specifically announced that they were for 1080i HDTV signals for the xbox system. Ah well, I've heard Monster Cables are usually faulty and junk. I think I'll buy a $20 xbox cord and see if it works.

Yeah so I went to the store and bought some cheap $20 HDTV Xbox cables. Put them in the 480i/1080i slot and started up the xbox. The dashboard was crooked but when the game started up it worked fine. I then put them in the 480i/480p slot and they dashboard was fine, and so was the game. I guess this is proof that the problem I had was with the monster cables.
I didn't really see a big difference between the normal game and the 480p version, but maybe with the Xbox360 and 1080i games, there will be a bigger difference.

Also, I have a widescreen 27" with component Y,Pr,Pb jacks, but yet it doesn't support the HDTV cables. How does that work? I mean I tried the 480p on them and the screen just scrambled when my Xbox started. When I turned off 480p in my Xbox options, and just ran the game through the cables with no HD turned on, it worked. Why have the component jacks when they're not supported?

I've done a little looking in the 27" manuel, because it is fairly new so I still had it. I don't know if this will look right but I'll try to make a picture.


.............Y.......S-Vid............
......R....Pr....................
......L....Pb.....................

It seems that all these component jacks are for is transfer a Component picture from a DVD player with the same jacks, into the TV. They are not for deciphering Hi-Def picture, hence the TV is not a HDTV.
The 27" will however support S-Video.
At least my 52" will support HD.

I haven't noticed much with 480p only games. Where you can see a difference though is the widescreen games (madden for instance - you see more of the field then someone without WS) and games that support 720P. Since you're TV doesn't support 720P, it may bump it up to 1080i - I'm not sure how that will affect quality - my projector is 720P native.

Try out a 720P game though - you'll likely see the difference there.

You know of any off the top of your head? I thought Farcry would be one, or at least Doom (when I was looking in the store) but both were only 480p. I'd love to see what one looks like....but I only have a month left for 360. And now I know that my HDTV works with games, I can't wait.

HDTV Arcade (http://www.hdtvarcade.com/xboxlist.htm) is a good site and lists what each game supports.

Off hand, Amped2, MVP 2005 and Xmen Legends all support 720P. Madden 06, Halo 2 and Project Gotham Racing 2 are all 480P, but supports widescreen. While you don't get a picture with Widescreen, you do have a nicer view.
