I am not a fan of the Lumagen Radiance Pro. I have had two units with 18 GHz input/output cards. Both had updated firmware and both exhibited unstable handshakes on multiple 4K sources for both of my 4K displays when there is a resolution change, including Oppo and Kaleidescape.

When I went direct from these sources to the projector or replaced it with an A/V Pro Connect 4K matrix switch, I had none of those problems. My ISF calibrator did indeed wring a great picture out of the Lumagen, but he himself could not explain or get comfortable with the blackouts. We were constantly reseating HDMI cables, etc.

Having similar issues talking to my LG OLED too.

My UHD722 is a week old and so far I've had the pink screen twice (cured by hard power cycle using rear switch) and numerous instances of lock failure resulting in a blank screen (cured by switching inputs using the front panel) - never had any of these with my HD621.

Disappointing for such an expensive piece of kit.

Uhm... not to turn this into a Lumagen thread, but people should be aware that the Radiance Pro is still in beta phase (unless this changed since I last checked), which means this is can happen. If you have problems, get in touch with Jim and I'm sure thing will be sorted out sooner or later (which sounds worse than it is with multiple firmware updates each month for a beta product).

As I indicated in my other post, my experience has been mixed and I agree it does indeed feel like a beta product.

Handshaking is slower than with the HD621 and sometimes lock is lost requiring a source change.

My main issue though was with Dolby Digital not being recognized on some sources and therefore the bitstream being corrupted by filtering and upsampling. I figured out a workaround involving using the digital out of the Sky Box directly into the G65 and using the HDMI In on the Oppo for the Fire TV (The Oppo decodes DD to LPCM which the 722 can handle). All a bit of a mess though.

I believe Meridian regard this as a bug not a setup issue (they have my config file) and are working on a solution, I guess in Firmware.

Hello - I'm back again and after long trial and error attempts - first alone, then with my M-Dealer finally success.

In short, it was all due to the HDMI cable. What previously worked with 4K cable with the transmitter between a 7.5M piece and a 5 meter piece between the Oppo 203 and the SONY VPL VW500ES no longer worked with UHD722.

An Audioquest Forest HDMI cable in the 15 meter version brought immediate success. Now all sources work fine - Oppo, AppleTV and NVIDIA Shield in 4K, MacMini and SatTV in 1080P HD. The handshake process is now fast and reliable. Quintessence of my long configuration odyssey is, the UHD722 is very demanding in terms of HDMI cable quality. The mentioned Audioquest Forest cable is not cheap (15M about € 500.-) but the success with the image quality and connectivity is worth this issue.

If you knew all this from the beginning, you could almost call the UHD722 Plug and Play.

My hope of using the 2nd HDMI output for a monitor is buried, at least until now.
Thanks for all contributions and ideas here in the forum and to the great service of Meridian UK and Raymond Lacoste, AV Emotions - Meridian Switzerland.

Hi,

I am running a Ruipro cable with the UHD722. Works fine.

Cheers,

It's been a while since I last swapped out M gear. With the issues experienced by some on the boards, can you guys give a quick review to my install steps?

1. Connect all HDMI to outputs
2. Connect MMHR from 722 -> 861
3. Connect SpeakerLink from 722 -> 861 (ok to use standard ethernet cable or is SpeakerLink from M necessary?)
4. Connect to HDMI sources
5. Power up 722
6. Hook up 722 to PC via RS232, run M-Config
6a. Download setup from 722 to M-Config
6b. Change sources in M-Config and send back to 722
7. Hook up 861 to PC via RS232, run M-Config
7a. Download setup from 861 to M-Config
7b. Update HD621 to 722 in 861 file and send back to 861
8. Make popcorn and fire up a great 4K movie!



My Questions:
A. Are everyone of the above steps necessary? Did I miss any?
B. Per item #3, is SpeakerLink needed or is cat6 ok?
C. Will the process above destroy MRC in my 861? I think I recall MRC being something you can't download from the 861. If so, will finding my original 861 file where I did the MRC with the installer be a better option?
D. Any recommendations for a stunning 4K movie? I'd like to pop the cherry of the theater with a good one!



Anything else I'm missing?


Thanks all. Much appreciated smile

As an update, the UHD722 is plug n play, provided you don't change sources. No M-Config needed! Other other connections steps were done. I used Cat5 for the SpeakerLink connection and it worked fine.

Not sure if the sound quality would improve with M's SpeakerLink cable, but I have a hard time seeing how it can improve the sound of 1's and 0's. A bit is a bit, no?

Thanks SomeGuy, I just got word that the UHD722 is at my dealer so I'll pick it up soon and will go through the setup. I remember that I did push config to the HD621 the last time around so I will probably do it just to be safe and consistent.

Regarding better SpeakerLink cables, the general advice is get high quality cat6a/7 cables (the best shielding) as a baseline.

Thanks Crion!

Any recommendations on high quality Cat6a/7?
