U-VERSE BLACK CRUSH
This is an alert for those using a U-Verse receiver and experiencing a significant loss of detail or a picture too dark: Its well known that some U-VERSE receivers have a bug sending a non-standard signal through HDMI. More precisely, they send a RGB range of 0-255 instead of 16-255, causing the so called black crush if your display is set to standard mode. One of the ways to correct this is to set the HDMI/DVI RGB RANGE, under the picture settings, to AUTO instead of standard. If you are processing the signal through a AV receiver or any other video processor, this will not work because the signal from the processor will be recognized as "standard". Make sure, in this case, to avoid the processing sending the signal as "pure" or "as is". Many posts on AT&T U-VERSE forum make reference to this problem but so far no fix has been sent. This affects ONLY HDMI , components will send the proper 16-255 range.
