Hey guys. My family just bought a new, 46-inch Samsung LCD. Previously, I had a regular tube television for the past 4 years. I am not trying to connect my Xbox360 with the hi-def-settings. However, I do everything right, plug in everything where it’s supposed to do, and flicking the switch on the plug to “HD.” (The one going into the 360) But, there’s no picture when I do this. When I plug it back in to standard def settings, it will go on normally. What can I do to get the HD going?

I just got this on Sunday, I don’t even have the HD cable box yet. Could that possibly have an effect on this?

Have you plugged in the right cables? Blue, Green, and Red?

Is there a chance you’re outputting it at an HD resolution that isn’t compatible with your HDTV?

I’d try lowering the resolution to like 720p through the xbox settings. Also not that if you’re using the HD settings, you need to use the component colored cables (green red blue) instead of the standard video cable (yellow)

I think Nesk is right and you’re probably using the wrong cables. Plug in everything except for the composite (yellow) cable.

Hey, I got everything plugged in right. I don’t have the yellow plugged in, and I have both red ones, the white one, green, and blue plugged in. I can’t get a picture on the screen in order to switch the output. And, I did switch the little thing on the plug to HDTV. This is why I am so perplexed.

are you sure you don’t have the two red ones mixed up? and are you sure you chose the right video input from your remote?

What resolution is the Xbox set to output to?

It looks like it isn’t the red plugs. I tried switching them around both ways, no difference.

By what resolution, do you mean the resolution on the TV or the Xbox? I can’t get a picture on the Xbox in order to change the resolution when I plug in the HD plugs.

first, on the cables put it to the standard definition. then load up the xbox, then go to the display settings to choose one of the HD formats. then it’ll say something like your cables aren’t setup for it. then flip the switch on the cables to HD. the console will restart and you should be displaying an HD picture.

So, just getting this right.

You have the component (green, blue, red) cables plugged in from the Xbox to the TV, and the AV cable is set to “HDTV”. When you select your input to Component, you get no picture.

BUT. When you have the composite (yellow) cable plugged in, the AV Cable set to SD, and your TV’s input selected as Composite, you get picture.

This is correct?

Alternatively…I’m assuming your TV has HDMI. Why not just use an HDMI cable?

might not have an hdmi xbox 360

Hopefully he’s got one then.

did you get this figured out? its possible that you weren’t on the right input. try going through all of them, composite 1, 2, etc…

or maybe see if you can find a friend with an hdtv that you can try it on
or a friend with an xbox you can try your cables on

that way you can isolate the problem whether it’d be the tv, cables, or the xbox itself.

Okay, I got this fixed. here was what was wrong. I was unaware that plugging in the other red, green, and blue plugs (Component plugs) was a different input that had to be selected from the regular AV in input. That’s what was the problem, I was selecting the wrong input. But thank you guys for helping!

No problem man, enjoy gaming in HD.
