HDTV (Samsung): HDMI : Low and Xbox360: Standard / Source. (OK)

OR

HDTV (Samsung): HDMI : Normal and Xbox360: Standard, Intermediate or Expanded (-won't matter) / YCbCr709 . (Better)

OR

HDTV (Samsung): HDM I: Normal- Xbox360 with Reference Level: Expanded / HDMI Color Space: RGB . (Best)

The optimal settings should be HDMI normal and reference level Expanded. That would give you a full RGB signal and levels. HDMI low and reference level standard will give you limited RGB signal and levels. Either will look fine as long as you have them set up properly. If you set it for a YcbCr color space you shouldn't be able to change your TV from normal to low because that is a video signal and RGB levels need not apply. (at least on my TV you can't)

When you connect your console to a TV or monitor, the console uses default settings based on your TV and cable type. In some cases, you can change these settings to improve video quality. If you use an HDMI cable, the console automatically selects the best settings.

Basically let the Xbox and tv do its thing. It matches best settings automatically. Mine defaulted to rgb. I am using hdmi on my LG 55" led tv.

Yes, RGB is generally suited best for games. YCbCr for movies.

So keep it on Auto. Ref. levels to expanded if your TV can handle it. If the greys and blacks look too dark (often referred to as a Black Crush), you can set it to Intermediate. If you still can't see detail in low contrast scenes, or there's excessive color bleeding in dark scenes, you'll need to set it to Normal.

Hope this helps. smile.gif

why should i set the reference leve lto expanded or intermediate? i thought that standard is the correct setting to get the colors to look the way they should be..

^^ Expanded.. ONLY if your TV makes the greys and blacks look accurate. Most TVs don't. And you would be right when you say Standard is most likely the best setting.

I got mine set to Standard as well.

Cheers.

Standard and Expanded should only apply in RGB color space.

It's a non-standard way of getting there, but probably looks fine if your display is flexible enough.

Games are native RGB/expanded. Video is native 709/standard.

HDTVs are built for 709/standard, monitors are built for RGB/expanded. Nowadays there is precious little difference between a TV and a monitor, and most HDTVs are flexible enough to support monitor specs.

So 709/expanded is a weird combination that isn't true to any source. But the video chip in the 360 can convert to whatever with little degradation, so it barely matters.

You could make a solid argument either way that RGB/expanded or 709/standard is "correct" for games on the 360.

Yep, Standard works great. Games generally respond better to RGB, as that's the source. I've selected the Auto option. So it simply changes to YCbCr 709 for movies. Intermediate and Expanded are just too dark on my TV.

If you set your Xbox to YCbCr 709 I don't think the reference levels apply any more. All three settings (standard, intermediate, expanded) should look exacty the same in that scenario. Idk if the the Xbox is doing some kind of conversion or if it just defaults to the correct black level for YCbCr 709.

^^ it just uses the default values on this color setting. Reference levels only apply to RGB.

No. Set it to auto or source.
