Hi Greg

You are probably right suggesting two cables, I suspect in collaboration with someone like Audioquest the net cost would be minimal, didn’t the HD621 come with three ‘high quality phono cables’? So it’s not really setting a precedent.


Always learn from the mistakes of others. You can never live long enough to make them all yourself.

@Crion
Meridian are in the loop.

@ ...
It was recommended to use higher-spec HDMI cables due to the higher-bandwidth requirements of 4K etc, but it was not stated as a requirement.
Note : My dealer has been more than helpful / supportive - as always...

However, the point is that if the UHD722 requires use of higher-bandwidth cables, then that's not explicitly stated - and should be.
It could be the case that the UHD722 uses a part of the higher bandwidth / frequency spectrum to initiate lock or communicate or to analyse / pass-on the signal - which then creates the need for higher-capability cabling, but in that case it should be known - and therefore part of the mandatory (minimum) environment / operating parameters.

The use of 4K-compatible cables is a must in a 4K environment / system.
The use of 4K-compatible cables was recommended when exchanging the HD621 for a UHD722 - but was not mandatory.
I don't expect to have to replace anything when going from a full-HD system to a full-HD system with one upgraded component under the basis of simple recommendation - but if I know that the component will fail or render my system dysfunctional if I don't exchange the cabling then that must be made clear from the outset.

It appears that after the initial firmware update all of the other problems experienced were solved by cable updates.
If cable selection is really symptomatic of the problems - and they're not the root-cause - then that should be measurable and repeatable, especially as we're talking about digital technology.

I'm not angry or upset (yet!), but I am annoyed - both by the necessity of regular system hard-reboots but also by the very poor level of error & proof-testing displayed by Meridian.

I've updated the firmware on my UHD722 and replaced all the HDMI leads with Audioquest Cinammon (which are 18.2 rated at the lengths I use (< 3m) but this problem still exists even on full HD. (I got so fed up that I leave my Sky Q and Oppo 203 running 1080p until I want to watch something in 4k when I'll switch for the duration of the program and then switch back).

I get the pink film issue probably a couple of times a week on power up. Never had a problem with my HD621. I also get the occasional illegal format msg on my LG OLED.

The cure is always to pull the HDMI cable at the TV end (it's the most accessible) and re-insert. I tried reporting to M via their website and had zero response. Right now I'm seriously considering going Trinnov.

GParrington, do you have a second non-LG TV to see if you get any "pink" handshakes on that as well?

The cure you list, disconnect the LG-TV does sound interesting. But could it be specific to a model or generation of HDMI input boards on LG TV's that would need a second handshake sometimes(?) Can you go into the About menu on the LG-TV and check for Firmware updates?

Any of you running the UHD722 with CEC enabled?

Unless you are actively using the ARC functionality, my experience tells me that it can cause a lot of problems when machines from mixed suppliers are trying to work together, even when each machine is excellent by itself, CEC is just a nightmare from a compatibility point of view.

I do not have the UHD722 in my system yet to test this hypothesis, but it's worth a try to see if it improves stability.

I'm almost certain I will experience this problem as well, currently running a 1080 system with a mixed bag of high speed HDMI cables.

I'll report back when I have the UHD722 implemented and updated in my system in a few weeks.

Crion,

My LG (a 55E6V OLED) is running the latest firmware from LG and ran perfectly fine with the HD621 in place - never had a problem with HDMI handshake; invalid format or pink screen. A straight swap of the HD621 for a UHD722 and the problems started (note this was on the same 1080p settings as I had run the HD621 on).

Learning that the UHD722 was cable picky I swapped to Meridian recommended Audioquest cables which made things slightly better but frankly not much. I've also made sure that CEC is off everywhere.

A general web search reveals that LGs can be a bit troublesome with HDMI but given that my problems only started with the installation of the UHD722 all the fingers point to it.

Not sure if this will help anyone but I have dealt with HDMI handshake issues with my JVC projector in the past when using 4K products and it has been been talked about in avsforum.com threads for awhile.

The most helpful tip besides having high speed cables deal with cable length. Obviously long cable runs (more than 8-9 m) are a problem but so is a short cable.

Using anything less than 2 m length gives handshake issues (at least with the JVC projector).

This may have already been stated and I don’t have the UHD722 to try it out.
Maybe someone can test this out in practice to see if it makes a difference.

I’ve had my UHD 722 less than two weeks and I’m now experiencing the pink screen. The easiest thing for me to do is unplug the Apple TV and use Android Smart TV instead or plug the Apple TV directly into the tv. I can pass the sound through to the G65 without any processing. Not a whole lot of difference in sound quality.

@Rolski

Just an update on my experience. I have updated my cables and installed the latest firmware. Don't ever see the pink screen but do see a white-grey patterned screen sometimes depending on how I switch on (bring out of standby) the various components.

All is well if I

1. Switch on Sony TV
2. Switch on Sky Q or Oppo device
3. Switch on G61R/UHD722

I can then change sources with no bad effects.

However if I switch on the G61R/UHD722 before the other devices then I sometimes get this white-grey screen which can only be cured by switching to the Oppo 203 once or twice OR power cycling the G61R/UHD722.

Not good but I can cope.

I'm assuming some of the problems are associated more with my Sony TV which is 4k but a late 2015 model. It has its own peculiar flakiness. During the recent BBC 4k trials for the World Cup / Wimbledon the TV was not listed as compliant with the BBC's 4k HDR requirements. Fortunately during Wimbledon Sky Q was transmitting a 4k channel which I could receive.

I am happy with the UHD722 for the moment and trust M will solve all these gremlins eventually.
