Thanks, Neil. Good job. The 1080p problem MIGHT be down to the DVI-HDMI cable, with DVI almost being put to its limit (bandwith) in conjunction with its length. DVI to HDMI is troublesome, particularly regarding colour space conversion though that doesn't seem to be the problem. OTOH, it might due to the fact the tv is not 1080p certified. Let's hope not.
The reply from Mirai support will be interesting.

Cheers
