Most TVs won't do RGB 0-255, so that option isn't mentioned. If your TV does, then go right ahead.

I think most TVs nowdays do 0-255. Samsung, LG, etc. call it different (high, normal, low, etc ... black levels).

I think it is a mistake if your guide doesn't mention the best configuration for htpc. New users with TV that does 0-255 will configure wrong their GPU output.

No, it is definitely not a mistake. Using your TV's full range option is not recommended:

Q: My TV supports Full mode, shouldn’t I use this?

A: No. TVs support Full to make them easier to calibrate. Most TVs will not display a black level below 16 because video content should never have it. By letting you see Black 15 or 14, it can make it easier to calibrate the display and get the black level correct. However, you really should not use this as your main setting as most displays are not designed to display levels below 16, and often introduce color tints when doing white levels past 240 or so. Additionally, if you restrict yourself to levels 16-235 you wind up with a brighter image with a better contrast ratio, as you can turn up the contrast level higher. Contrast Ratio is the thing your eye notices most, and so it will produce a more pleasing image.

madshi, nevcariel, etc. recommend pc levels:

My recommendation is always to set configure your display so that it expects PC levels (full range). This has 2 important benefits: (1) Levels will be correct for everything, including games, photos, applications and video playback. (2) There should be no problem with image quality.

If your display can't do PC levels, or if you have good reasons for not using this solution, then you have 2 alternative solutions:

(a) Either set the GPU to limited range and madVR to PC levels. This means madVR will render to PC levels and the GPU will afterwards stretch the madVR output (and desktop, games, applications, photos etc) to limited range. Using this approach still has the benefit of having correct levels everywhere. But image quality might suffer because the GPU usually uses a rather bad stretching algorithm, which can introduce banding artifacts.

(b) Or set the GPU to fullrange and madVR to TV levels. This will result in good image quality (no artifacts) and correct levels for video playback. However, desktop, games, applications and photos will have wrong levels
