HDTV picture on one TV, but not the other HDTV?

My XBOX 360 Elite has been working perfectly on my bedroom full HDTV (1920x1080). This morning, I moved to my living room full HDTV (1920x1080 too) without problem, but on returning to my bedroom HDTV, I get no XBOX picture, and the TV reports "No support signal". The bedroom HDTV still works with my laptop with the the same cable, and same HDMI port.

I've (a) switched-off everything, and turned on again (b) Done a console reset (c) Cleared the cache (d) read the FAQ (e) Tried setting default/optimal and specific display settings (f) Tried different HDMI ports.

Is there anything else that I'm missing, or can try?

Have you tried to reset the display settings? I'm not sure if that's what you mean by setting defauly/optimal or a console reset.

Did this solve your problem?

Sorry this didn't help.

This is very strange. One thing it could be is a display setting on the xbox which isn't supported by your living room TV. It's unlikely but if your living room tv is one of the earlier HDTVs it's a possibility. There's a few things you can try which will narrow down the source of the problem:

1. Try using your laptop on your living room tv using the HDMI cable and see if you get the same problems as with the xbox. If you still get no signal then you can narrow it down to the TV itself.

2. Plug the xbox back into your bedroom tv and see if you still get a picture. If not then there's something wrong with the xbox.

3. If you can get the xbox to display in the bedroom, write down the current visual settings. Then go through the tech specs of both tvs and see if there's anything that either tv supports that the other doesn't.

Hope this helps!

[EDIT] Oh, forgot to mention something else it could be. I've had trouble with my PS3 in the past getting it to talk to the tv over HDMI, giving the "no signal" error. It's usually fixed by restarting the console several times, eventually it works. Try this first before everything else, could save you some time and effort.

To Miss Portia: Yes, I've tried resetting the display settings, to no avail.

To Braunman: Thanks for the suggestions, unfortunately no solutions yet. I'm going to try with a new HDMI cable. It's as if the XBOX display settings won't update. But we'll see.
