Wrong signal on HDTV-Beamer 1440x480i instead of 1280x720

[waldigunde]

Hi, I have the following problem

I plugged my XBox360 via YUV to the Denon AVR 3806 Receiver. From the Receiver I go via HDMI to the Hitachi TX200 Beamer. Now the beamer shows that it gets the following picture input: 1440x480i @60. In the settings of the XBox360 I chose 720p @60 (I tried also @50).

With the Denon DVD 3910 it works with no problem. I plugged it via HDMI to the AVR 3806 and the beamer shows 1280x720 @50. This is correct.

What could be the error in the settings of the receiver/beamer (The receiver can't scale) ?

Thank you for your answers

Try choosing 720i on XBox...somehow your PJ seem to be getting 720x480i signal where the interlaced double scan is being confused with double picture width (which basically is true since it recieves 2x720 horizontal pixels is interlaced mode to draw a fully timed frame...I'd really suspect the receiver, especially when you claim that it cannot scale (but how do you know that?) Of course check HDMI options on the receiver...it may also really not be able to correctly interpret HD res...

I solved my problem. On the YUV-output cable of the XBox360 there is a small switch, which I had to switch to HDTV, now everything works.

Thank you for your answer.
