Apple TV HD HDMI Cable question

Setup:

Panasonic PT-AE2000u Projector
Apple TV HD
Sony DA3300ES HDMI Receiver
Gefen HDMI Super Booster
HDMI cables from 2007 (probably HDMI 1)


I recently purchased Apple TV HD and am having serious dropouts. My HDMI cables are very old. The HDMI cable that connects the receiver to the projector is run through the ceiling, so it's difficult to change.

I'm assuming I'm having this issue because I'm using an older HDMI cable version. Is there any way to salvage this cable (because it would be difficult to run a new one). Can the signal be boosted?

I tried testing the connection without the receiver (projector directly to apple TV) and still had the same issue.

Any advice would be appreciated.

Thanks

My rule of thumb is this:


For 4k HDR up to 25', a passive Premium High Speed HDMI cable (with the QR label for authenticity) should work. Over 25', an active hybrid fiber cable is recommended.


For HD (1080) then almost any well made passive High Speed HDMI cable will do.


The most reliable connection is source to sink with no wall plates, extenders, adapters, etc in-between. HD (1080) is a lot more forgiving with its connections that 4k HDR.


For clarification, Apple TV HD is 1080. Apple TV4k is 4k HDR.

I never trust an atom, they make up everything.

How long is your cable. Start there. Dropouts can be due to any number of things. The most common is an HDMI cable that just isn't robust enough to handle the signal over a given distance. You should replace the cable. I'd try a new cable (Premium High Speed) by just laying it out on the floor first and connecting it directly to the pj (do not use the HDMI booster). If that works then try it with the booster. If that doesn't work, then you know that the new cable is probably ok and it's the booster. Trial and error.

Explain your HDMI chain in more detail. How long is the HDMI cable from the ATV to the receiver and are you using a wall plate to connect the receiver to the in-wall cable (which goes to the pj)? Where is the booster in the chain?

The HDMI cable is 30'.

Receiver --> HDMI Cable --> Booster --> Projector
I've also tried
Receiver --> Booster --> HDMI Cable --> Projector

I have no problems when using an older version of Apple TV (from around 2012).

I was hoping there was some other option because it's a big deal to replace the cable in the ceiling...

Thanks a lot...

Which Apple TV do you have? The AppleTV3, AppleTV4, or AppleTV4k? What settings are you using on the ATV and are you just trying to push 1080 to the pj?



It could be a setting with the ATV (depending on exactly which model you have).



Your receiver is also an older model. It's not capable of HD Audio (Dolby TrueHD, DTS-MA, etc) and the HDMI ports are only at the 1.2a standard. HDMI 2.0 is the current standard so even though HDMI is backwards compatible you will only be able to use the options that are in-common. IOW, pushing data at the HDMI 1.4 or 2.0 from your source to your HDMI 1.2 receiver will only be able to utilize the options sets that are available to HDMI 1.2, including bandwidth. It can work but is not reliable.


Your pj has HDMI 1.3 ports so that too could be an issue. The Geffen Super Booster is HDMI 1.3.

It might not be the HDMI cable at all. Just test your setup with an HDMI outside of the wall to see if it fixes the problem.

I suggested that back in post #4 but it does bear repeating.

- what is the 'Booster' device and how is it powered?
