Default Error: Cannot display HDMI over device

Why am I getting this error when I start the system up?

After a few seconds, it goes away. But it's consistently there. The HDMI cable has been changed, jostled, moved, and cussed at.

Pic quality is fine and works great when the error goes away. It's actually the only problem with the setup and we're in our sixth week or so since ditching Dish!

When you say, "start the system up" what exactly are you starting?

It happens when we turn on the DVR. Every time. The TV takes a minute to warm up & display right so we often start it up first.

But regardless - even if the TV and the DVR are both turned on at the same time, we'll get that message.

Why not just leave the DVR "on" as you call it? The DVR is never "off" as long as the power is applied, only in a sort of standby mode. Even the video is not cut off, it goes to a blue screen with the message to "Press OK to watch AT&T U-verse TV" so you may as well just leave it on.

one set will occassionally blink off while I'm watching something and give me that error. I swapped the box with another one that's not hooked up to a high def TV and it still does it. Doesn't happen enough to merit any further action.

The why is because HDMI is not ready for prime time yet. Until every manufacturer conforms to the standards in every detail, it won't be. The problem could be either in the U-verse box or the TV. Hard to say which. It is a timing problem where the TV did not respond to the U-verse box fast enough. Could be the TV is slow turning around the handshake request (EDID) from the U-verse box or it could be the U-verse box is not giving enough time for the TV to respond.

I had a situation similar except I didn't get a message, just a green screen ocasionally. Every source could be different. This was when I had the HDTV HDMI connected to my HTPC. I fixed it by getting one of these: Got HDCP Connection Problems?

When I had the same HDTV connected to a U-verse box, it never gave me a problem, just when I switched the HDMI to come from the computer. One, or both, devices did not strictly comply to the HDMI standard.

Default HDMI Error

Hello Im a Uverse Phone tech and I happened to come across this page while on break here at work...

The error is due to the HDCP (High Def Copyright Protection) Profile we are using. We are using the latest Version 1.3 .

Your absolute best bet is to use a new HDMI cable on your box to TV.

And yes it drives us crazy too :-)

No I am not a corporate sponsor Im just a tired tech.. :-)

and bored..... very bored

If the Moto box is in strict compliance with 1.3 then the issue is probably with the TV. Not that it helps the OP.

yes, it DEFINATELY is with the tv..

on the newest tv's that conform to hdmi 1.3 or 1.3A, the system boots up just fine..
But, on my older tv's, (older meaning more than 1 year old), it can be a challenge getting every thing to start properly, without restarting one or more of the boxes/tv's...

I know what you mean. I had to get one of these to allow it to memorize the EDID. After that no more problems.

Got HDMI/DVI Connection Problems?

Default This issue is be-deviling me!!

Read this thread with much interest as this HDMI sync issue is driving me crazy! I've got a new Pioneer Kuro. Owners manual says it's fully HDMI 1.3 compliant. I also have 1.3 HDMI cable I purchased from Monoprice. Yet, since the whole home DVR push that went through in August, I suddenly have handshake issues. Up until that time, I had zero issues with the handshake between the STB and my TV.

I'd love to hear Rary's thoughts on my situation.

I have found that the TV has to go on first, then the box, for there to be a trouble free handshake..try doing that manually and see if it works that way 100% of the time..
there is no doubt that a new technology tv like the Kuro should work without any issues..
