HDMI video range - Black Crush

Check out the prices at Monoprice.com.  Their prices are really good, and I bought a 20 foot hdmi cable that has the transformers in the connectors to compensate for the length of the cable.  Also, the cable is really thin and flexible so it can be run any way you need it. This cable only cost me about $9 at the time.  I bought 3 more 6 foot cables for about $2 each.  This was around March this year so the price should not be much higher.  Go check out that site.

No, he was objecting to your phrase "like every other cable provider," since AT&T is not a cable provider.

However, I thought that they had fixed the issue with the black crush years ago.

They did fix it on the Sigma Designs-based STBs (Motorola VIP1200, VIP1216, VIP1225, Cisco IPN330, IPN430, IPN4320).

The problem has reappeared on all of the Broadcom-based designs (Cisco ISB7005, ISB7500, Motorola VIP2250).

Here is the old HDMI calibration thread for those interested in the history of this problem:

Well that explains why mine has looked different.  I received a VIP2250 about 3 or 4 months ago and I thought maybe my eyes were playing tricks on me.......Guess not.

SomeJoe, Do you think AT&T is sufficiently aware of this?

Well, there are threads referencing the issue all the way back to when the ISB7500 was first released.

I'd say AT&T is probably just as aware of this issue as they are of any other issue.  Interpret that how you wish.

It may be worth it to see if one of the mods can bring the issue to the attention of AT&T's technical team just to make sure.

On the previous STBs when the problem was affecting them, the issue was only present on the HDMI connection.  Black levels were correct on the Component outputs.

It may be worth seeing if the same behavior is present with this issue on your STB.

I sent it to the U-verse care group.  That's about as much as I know how to do with it.

That should work.  They'll forward it to the right people.  As for getting it fixed, who knows.  It took nearly 2 years to get it fixed in the 1st-gen STBs.

I told them about it on the getsocial site and they were not aware of it, although another user was having the same problem on a rear projector TV too at the same time.  We both have 2250's.  I was able to get it to disappear w/a Non-Destructive Disaster Recovery, but the next reboot would bring it back.

I am unable to get a good picture on HDMI (it's actually worse than the original black crush problem), so I've been on component w/no complaints on PQ.

I have been informed that this issue is known to development and the fix will be provided in an upcoming release.

I know it's not a lot of news, but it's what I've got.

I had never heard of Black Crush until just now. I have recently switched to Uverse from DirectTV and first noticed the issue watching the final of Boardwalk Empire. I REALLY hope this is something that will be remedied soon as I like Uverse's other features so far... 

I guess an ETA is too much to ask for?

This is an old thread, but I ran into this issue today with a new TV I just bought and an ISB 7500.  The picture was great except for the super dark blacks with no definition.  aka, "crushed"

The TV, a Samsung plasma, does have a setting to change the HDMI RGB range and changing that allowed for a much more balanced picture, but now that change impacts everything coming out of my AV receiver since I use it for HDMI switching and just run a single cable to my TV.

So I'd definitely like to see it fixed.  

Thanks.

I am having the same problem.  I was "upgraded" to the VIP 2250 due to issues with my old DVR.  Ever since the upgrade the HDMI picture quality has been abismal.  I have had it replaced once and it is no better.  There are no details in any dark areas on screen.  When I watch House of Lies Don Cheadle has only half of a face (the half in shadow just disappears).  I am getting the run around from customer support.  If there is not a fix for this soon I will be dropping my uVerse service...

Have there been any updates from AT&T regarding a firmware upgrade?
