HDMI video range - Black Crush
Hopefully somone can help me out here. This black crush issue is driving me crazy. After much research it seems as if the Cisco isb7500 and 7005 boxes send out RGB 0-235 instead of the standard RGB 16-235. Why in the world would they design it like this?
Any how, I have an Epson 5020 projector in the basement with hdmi in the wall so running the component cables is out of the question. I can change the range on the projector to extended but it throws off all the colors and disables certain features.
Is there any way to get these boxes to broadcast the 16-235 range through HDMI like every other cable provider does? It has been extremely frustrating since switching from TWC to get a decent picture.

I happen to stumble upon this thread, and have to say that this has saved me from taking a bat to my tv. I have a Toshiba 55 inch LED. Since the day I got it I just could not get the settings right for the picute. Tried everything, even a calabration disc.
Well, just got a Samsung plasma, and same issue. Then I see this post and decide to try hooking box to TV by component. What a difference!! I can make detail out in the dark parts and bright colors no longer look over saturated. Wish AT&T would fix the issue so we could use HDMI and get a properly formatted picture,

I am getting ready to switch to component cables. It is so frustrating that AT&T is unwilling to address the problem with the HDMI black crush.

I fixed it w/a Non-Destructive Disaster Recovery, but next time the 2250 rebooted, it had the crushed black problem again.

I have not gotten the upgrade yet. Currently my DVR can not connect to ATT servers and is giving me a red X. 😉

Still on the 2013 TV client firmware, fyi
Update: no it's not fixed, just watched a night club scene, totally dark.
