There are available settings, such as:
RGB Full Range HDMI
Limited: RGB output signal is output in the range from 16 to 235.
Full: RGB output signal is output in the range from 0 to 255.
Y Pb / Cb Pr
/ Cr Super-White (HDMI)
Options are: Off or On
BD / DVD Video Output Format (HDMI)
RGB Set to output in RGB.
Y Pb / Cb Pr
/ Cr Set to output in Y Pb / Cb Pr
I found this thread, which discusses it.
The correct setup for the PS3 is to match your levels. Either set your PS3 to RGB Full and TV to HDMI Black Level Normal or RGB Limited and TV to HDMI Black Level Low. Either setup should produce a similar picture and should not have crushed blacks. If you have crushed blacks, that means that either your brightness is set too low or your gamma slider
is too low (more on Gamma later). If you mis-match your levels, you'll end up with clipped detail or a washed out picture. It's essential that you match your levels and use one of the configurations above.
Set Blu-Ray output to YCbCr in the DVD/BD settings. Enabling super-white doesn't really change anything, it just expands the range, but virtually nothing takes advantage of this. It is useful for setting Brightness and Contrast, though.
Keep Black Tone disabled. Set Gamma to a level where it doesn't look washed out but shadow detail is still visible. Use Spears & Munsil or Disney WoW to set Brightness, Contrast etc. If you can set the Contrast control to a level that's high enough to hurt your eyes, turn it down to a comfortable level. Don't simply plug someone's settings in.
Also note the following:
-The Brightness control controls the black levels on your TV (Contrast controls white). If you set your TV up as I said above and display a full black screen, there should be a point where blacks won't get any darker if you start high and start to lower the Brightness control. This point should be about the same point as where you got using the S&M or Disney WoW disc to set Brightness. Your black levels won't get any darker than this.
-Gamma is mid-tone brightness, or how fast your TV comes out of black. Gamma is not supposed to affect how dark blacks can get (or how bright whites can get), but it does affect shadow detail. I don't own a Samsung but AFAIK
, Samsung's Gamma control doesn't work like gamma should, meaning if you lower the gamma slider, it technically actually increases the gamma. A higher gamma makes shadow detail darker and a lower gamma makes shadow detail brighter and easier to see. If the gamma is too high, shadow detail will be too dark, but if gamma is too low, the picture will look washed out. Gamma should be anywhere from 2 - 2.5 depending on your lighting conditions. For example, a bright room will wash away shadow detail so you'll have to lower the gamma (or raise the gamma slider
) to bring the shadow detail back out. In a darker room, it's easier to see shadow detail, so a higher gamma (or going lower on the gamma slider
) will work better because it won't look washed out. Again, set it so that shadow detail is visible but the overall picture doesn't look washed out.
