I've recently taken delivery of a UHD722v2 and currently it's working flawlessly - after the usual initial set-up idiosyncracies!

Something I've noticed however (perhaps it was there all along) is a pronounced Lip Sync delay on several sources, which might be caused by the addition of more 4K capable sources & displays in my system.
I've found that SKY Q needs up to 60ms of audio delay (which can be set on the SKY Q box itself) but other sources like Apple 4K TV don't have that option.

I've been looking at each source and although adjusting each individual device's internal settings might be the most accurate solution, I wasn't able to find any clear instructions or anything that worked for my 861v8 - but I've realised that a 'global' Audio Delay can or should be set in the HD621 / UHD722x.

I only use my UHD722x to strip out & pass on the Audio stream through one single Input (#4 - SAT) - I use my Lumagen to do all the other switching.

Does anyone else have experience / suggestions with Lip Sync & is there any known variation between sources?

1) SKY Q (4K) - 60ms
2) Oppo UDP-203EU (4K) - ?
3) Intel NUC 7i7BNH (?) - ?
4) MS Display Adapter (HD) - ?
5) Google Chromecast Ultra (HD) - ?
6) Roku Ultra (4K) - ?
7) Amazon Fire Cube 3G (4K) - ?
8) Nvidia Shield (4K) - ?
9) Apple TV 3G (4K) - ?
10) -

I'm hoping other people's experiences show that the signal output from the different sources is indeed similar (which would be logical), so that the UHD722v2 can be 'set & forget' to one common / global delay.
