Hopefully this isn't the wrong place to post a question about this, if so please accept my apologies in advance

I recently purchased a Philips 51inch HDTV (rear projection set) 51PP9100D from Circuit City during their Black Friday sale. I have noticed that while i am watching certain HDTV channels the picture is super clear (Discovery in HD, some of the INHD channels, ESPN, etc). However, when i am using my Xbox 360 it almost feels like i am playing it in SDTV. I have it plugged in using the component cables into the set, have the 360 detecting that it is a 1080i display and set up for that, but while I am in the game menus and things like that it feels like the performance isn't there and the picture isn't very clear.

On the advice of some people on the 360 forums I purchased a copy of Avia and calibrated the settings of the tv the best i could, but it just feels like i am not getting very good performance while gaming.

This is a long shot but does anyone have advice on this topic? Hopefully i have been descriptive enough of my set up and the problem I am having.

Thanks in advance for any tips or suggestions!

There is an actual switch on the cables for the 360 that can be set to either SD or HD... make sure you have it flipped over to HD, otherwise you'd see what you seem to be describing.

are you 100% sure you have the xbox360 output set to 720p or 1080i? Many people have reported forgetting to set the switch.. Also, calibrating with an AVIA disc isn't going to help as much since you would be calibrating based upon 480i/p where as with the xbox360 you would want to calibrate based on 720p/1080i. Playing a DVD on the xbox360 does not upconvert to 720p or 1080i.

Thanks for the replies. I actually realized there is a Xbox forum here so i posted there too. I have checked the cable and i have set my Xbox to output 1080i widescreen. I can always check that again. As for the Avia thing that makes sense to me. I guess i might be stuck with either my television channels and settings looking good OR my Xbox ones, which is a bummer.

do you have them on the same input? If so, does you tv have a night and day setting? perhaps you could do xbox360 set for the "night" settins and just adjust it as you see fit and then just click to "day" for regular tv.

I have my digital cable/dvr outputting into the HDMI input on the tv. I have the 360 going into the component inputs, so they are on seperate inputs. I am not certain about a day or night setting, i do have about 5 presets for different video settings though (a weak signal one, multimedia, sports, movies and personal)

I don't know much about DVD players (and very well may be wrong) , but I was under the assumption that most of them do not upconvert to 720/1080. If this is so what would be the difference using the Avia DVD with the Xbox or a DVD player ?

Doesn't the tv automatically upconvert the picture to 1080i or 720p, whatever it's native res is? I calibrated my TV with Avia through the Xbox 360 and it seemed to make a huge improvement.

sorry, I wasn't very clear.. Yes it is good to use AVIA or DVE. Yes, the tv converts in the case of using the xbox360 as a DVD player. Using a upscaling DVD player would be different, the DVD player would be doing the scaling.

Point being that sending your tv a calibration based off a 480i/p (only output possible for xbox360's dvd player) signal.. while DVD is playing may in fact be slightly different then sending a calibration based off a 720p/1080p signal such as playing the xbox360 games.

anyway my point was that calibrating based off a 480p/i signal to the set could have different (even if slightly) then if calibrating based off sending a 720p/1080i signal to the set. I'm sure you'll be fine.. I was just trying to guess why there might be issues.

Just out of curiousity, do you think it would be better (as far as 1080i and 720p inputs go) for somebody without an upscaling DVD player to use Avia going through a cablebox with the cablebox's output set at 1080i/720p only?

Thanks.
