I setup my xbox on Monday using the composite cables as I didn't have a HDMI cable at the time so now i have PSone quality graphics, but at least it's playable.

I borrowed a HDMI cable last night to try, but the TV just says no signal. When I goto the display settings the HDTV tab is greyed out. The TV is a cheap 20", but it does have a HDMI plug on it (only 1 lol).

I've used the HDMI port before so I can confirm that works and I've been told the cable is ok... I've got my own cable+xbox AV output thingy so I can connect my turtle beach properly which will hopefully be here today.

My next plan was to set it back to factory and start it up with HDMI plugged in.

Easy fix, get a ps3 lol!

Make sure your x box is only outputting 720p rather than 1080p/i (whatever xbox uses) as it could just be set too high for the tv if its only a hd ready one rather than full hd.

it may be that HD is turned off in the TV menu
my TV was like this , had to tick a setting to enable it (for sky)

I'll double check that doggy. Probably cos it's 1 of those cheapo tesco TVs or something lol

playing on the composite connection is interesting lol. I can't see people in MW3 if they have a gilly on!

Is the slide toggle switch set to HD on the lead on the back of the xbox?

I think because my console is the slim latest one it has separate HDMI / Composite outputs. I don't think I have that switch. I'll look when I get home now I have my new cables and also plug it into a better quality TV

Regarding only one hdmi input on the tv, been using one of these http://www.ebay.co.uk/itm/HDMI-3-INPUT-AUTO-SWITCH-HUB-SPLITTER-BOX-PORT-OUTPUT-/280701364418?pt=UK_Computing_Sound_Vision_Video_Ca bles_Adapters&hash=item415b1ae8c2#ht_1757wt_1187 with dvd/hummy/games. works well, first device switched on is put through to tv.

it's only the TV out of the caravan until we move out and get our own place. then we'll get a proper TV lol. cheers for the thought though :)

Using the composite lead to hook upto your TV, check the xbox settings menu. You may be able to change the output types in there too.

I know on my PS3 I had to change settings to allow the sound to go through the HDMI lead. :thumbsup:

Took me ages to figure it out too, till i went throo my tv settings and boom HD. But if i switch my tv over to say a tv channel my xbox goes into sleep mode til i switch it back then it powers back up. I have to have tv on first before the xbox too.

turned out the TV didn't like scart plugged in at the same time as HDMI. unplugged it to plug turtle beach into another port and the picture lit up lol.

cheers for the help.
