8K Arcana VRR 40Gbps arcana2

If you want to get eARC output from an HDMI source connected to a monitor without eARC - eg in order to route audio through a SONOS soundbar - this is a super expensive but (so far) reliable option

This is based on the 8K version as I used a 4K display and want dolby atmos+hdr and all that good stuff without any bottlenecks. I cannot say fot sure if the the normal HDFury would be enough. Audio works fine and "COMPLETELY FIXED" the notorius lipsync issue whe connecting a non-HDMI Input soundbar to a pc. Wish it let me run my computer at 144hz refresh rate but 120hz cap is still fine. This allows me to have no more OCD trying to find that perfect audio delay speed setting in video players trying to get audio to match the lips which I swear is impossible to achieve.

When it worked it successfully fixed the lip sync problem I was having with my TV and Sky Q box. However, it was flaky and would lose sync and need frequent re-boots. Too expensive not to work 100% of the time.

No matter what I do I cannot get an apple TV - Sonos - Samsung TV system to work. Once everything is dialed in, the setup works great -- for a few days. And then, randomly, either sound is completely gone until I unplug the arcana a few times or tv is stuck on no signal found page. Tried every suggestion by support (they always send you the same copy paste response and I've never seen them helping anyone resolve their issues in their discord), CEC is turned off, updated software, no fix yet. This copy paste response doesn't help anyone. Your product does not work. There's always an excuse. First you said it is the CEC, then you ask for some info that doesn't help you debug anything. The reality is this product does not work and what happens to me is the expected outcome. You have to regularly power cycle this thing for it to work. This is definitely not a buy and forget product. An overpriced, overpromising HDMI switch.

Pricey but does what it says and then some. Easy install and very responsive.

Powerful tool. Use the discord channel to get help.

Works great, as long as you know its limitations. I would highly advise talking to them in their Discord because I found the item description here and on their website to be incomplete. Most importantly, it does not truly fully support 4K 120hz. At the time of this writing, if you need it to do any scaling, you can only go upto 4K60hz, because it does not have profiles for 4K120hz. Also it does not have EDID support. If you are not scaling and you're just using it for pass-through, then yes it supports 4K120hz with VRR etc. I think they should have included some kind of HDMI debug function, because their support can really use more info to help you troubleshoot. Currently you have to scroll to each setting and take a photo of it to upload to Discord. In my case, I needed EDID with 4K120 to emulate in headless mode, but I was told in Discord that I need their "VRRoom" product instead. But it did fix a VRR issue with my Samsung QN95 TV (that I didn't even know was an issue), and I can visually see an improvement in some games.

It won’t work at all unless you unplugged and plug it back in every time you turn the TV on - every single time. It also won’t play audio from both the TV and an Apple TV 4K - only get audio from the Apple TV 4K. P.S. since it can’t be exchanged, I’ll have to purchase a competitor’s product instead
