It looks terrible through my HDMI
But looks okay through my component cables I don't understand it should look better through my HDMI
I have a audio quest chocolate silver coated HDMI
Well over 100$
The tech over the phone told me to try to switching to components because he heard of the problem before it's a bug in the system!
No doubt now

Please call At&t !

Re: screen is way too dark on HDMI

All tv providers, including U-verse have feed from distribution as either 720p or 1080i. Components cable is designed for this feed.

HDMI cables are designed for 1080p (blu-ray).

The receivers have to take the 720p or 1080i and modify for hdmi output resulting in "black crush". The software used in receivers is Microsoft Media Room, which was purchased last September (2013) by Ericsson is undergoing revisions.

A upgrade for the receivers with new Ericsson software is coming, am not aware of all changes planned but hopefully this will be one of them addressed.

Currently "best" to use components for feed from U-verse receiver to TV and HDMI from your DVD (bluray) to TV, changing input on tv to match desired source. This also avoids the shortcomings on some manufacturer models with HDMI handshaking issues when TV/receivers are turned off/on.

Re: screen is way too dark on HDMI

The component cables lag and do the handshaking the HDMI is the better quality cable ....
I'm paying for high-definition so I can use HDMI that is designed for 1080i all the way to 4K!
What's the point of having an HDMI if it doesn't even look as good as the component cable.
I have had Charter and DirecTV and the HDMI look better than their components.
This is a problem that should not just be looked over this is a major issue I will not be keeping this service is if it's not fixed.
I'm paying for high-definition and you can't get that good of quality from component cables as you do from HDMI .
And do not try to blame it on my HDMI or TV it is obviously your equipment that needs to be fixed this month!

Re: screen is way too dark on HDMI

Component cables are designed to handle 1080i.  Whether HDMI or component looks better is an issue of personal preference.

 

I personally expect AT&T to roll out a TV receiver update sometime in the next few months.  I have no better information than a SWAG.  I do not know if the crushed black problem will be fixed in the next update.  I do not know what other problems may be fixed or created in this next update.

 

However, if you're bound and determined to be unhappy, maybe you should start looking for the perfect service now.

Re: screen is way too dark on HDMI

It is not personal preference
When it lags out when somebody just moves fast
Anyway you look at the HDMI would send the information to the TV faster and better

Re: screen is way too dark on HDMI

Component cables are slow and outdated
Should not be forced to use them

It is a personal preference, and apparently not yours.  There is usually very little difference when using good quality component cables of a reasonable length (i.e. 6' or less).  By good quality, I do not mean to imply "Monster Cables."  I mean actually good quality, which can be had at a much better price.

 

I use component and HDMI depending on the TV and other connections necessary and available.  Both work fine for me at 1080i.  I see no difference whatsoever.

Re: screen is way too dark on HDMI

Have you compared the brightness and contrast settings of the two different cables? My TV has seperate settings for each input. Maybe your HDMI input has a lower brightness setting.

Re: screen is way too dark on HDMI

as a new uverse "customer" I must say this is the first coherent response I have ever heard from an att employee on this subject. Ive heard everything from I have bad hdmi cables to straight up "I don't know". 

  Having said that, there is obviously no time table table for the release of the new software or I assume you would have stated so. We all "hope" that fix is included in the update, but I'll believe it when I see it. 

 

 

Adambird, you are not the only cat with this annoying issue. I switched from dtv, which has amazing picture quality (when you have a signal)so I feel your frustrations. I have tried everything to get a better pictrue via hdmi but as you well know by now, that simply is not possible at the moment. Also, I suggest not ever spending more than $30 on an hdmi cable.  There are plenty of articles out there which show there is virtually zero difference bw a $10 cable and a $150 cable.  my last ditch effort to improve the picture quality was a hdmi cable with redmere technology.  15 footer with all the latest specs, and got it for about $30 on monoprice.com. That didn't make one bit of difference either. 

 

Anyway, I completely agree we are not getting out monies worth from att.  I have made my concerns well known with tech support but 99% of them ('my thoughts' excluded) are less than no help. They read from their que cards and don't know anything about the inner workings of the uverse sysytem.  I realize this wasn't a very productive post on my part, just wanted to let you know you aren't alone in this battle. Lets hope for the best in the next software update so we can get what we pay for.

The issue is that there are two ways of interpreting the numeric color values in the HDMI spec.  One interpretation uses all of the possible values in one 8 bit octet, or byte.  The other interpretation ignores the difference in the values from 0-15  (treating them all as 0) and 240-255 (treating them all as 255).  You get crushed blacks when the receiver and the TV use different intepretations.  Sometimes your TV will have "black level" setting you can change that will correct this by matching the receiver's interpretation.  As will Component Cabling of good quality, by avoiding this HDMI spec issue.  As you have found, the quality of your HDMI cable will not correct this issue.

 

The really sad thing is that this problem existed in the first generation of U-verse TV receivers and was fixed in firmware.  Then they came out with a new generation of receivers and the problem returned for the new generation.
