Club 3D DisplayPort 1.4 to HDMI Adapter

UPDATE: Email Support@club-3d.com for the new firmware - all my issues with the vizio TVs have now been completely resolved. 4k 60hz achieved on HDMI2.0 vizio m50-c1+Fury X. Yay! My older review is below for posterity, but no longer applies, as the manufacturer has fixed the issue. Older review: I got home at 5pm. It's now 730PM. I work in IT as a consultant and onsite emergency response. I'm pretty savvy with these things. I have a Fury X - you know, the card they advertised this to work with. I also have a vizio m50-c1. You know, a common and awesome 4k TV. I have 3 different HDMI cables that are 100% for sure rated for the 18GB+ bandwidth. As you can see in the video, the output, at best, will be 1080p, which my TV desperately wants to believe is 2160p. I tried my 7950, too. I tried my seiki, and can't get it to output 4k30, either. I tried literally everything I could think of, different cables, different ports, different video cards, and a laptop and a surface pro 2 - the surface pro 2 to output 3200 x 2000@60hz or anything above 1080p. Paradoxically, it'll do 4096x2160@30hz no problem. Based on this testing I have done, and considering this is a pretty standard, popular 4k TV and LITERALLY THE CARD THEY TWEETED ABOUT IT WORKING, I ASSUMED it would work. I am not sure if this is compatibility, echoing another reviewer's sentiments, or if they are simply shipping half baked lemons. I would HIGHLY recommend AGAINST the purchase of this product - wait for someone else to do it right. Personally, I will never purchase another club3d product again. EDIT Today, 3 days after receiving it, I have not received a response from club3d via email, facebook, or forum. I have tried all suggestions here - forcing 8bpp depth (although it does default to 8bpp and won't let me change it in 4096, defaults to 10bpp in 3840) I also found some varied recommendations on the forum... but what it boils down to is that it sounds like many folks with vizio TVs cannot get this to work in any way at all. I continue to be absolutely appalled by club3d's complete inability to respond regarding a product they just released. EDIT: A couple days later, club 3d did reply, and I worked through a massive amount of steps they suggested, many repeats of what has been said here, but for posterity, and hatred of my own time on the weekend apparently, I did it top to bottom, nothing. They sent me a fresh fancy firmware updater that was obviously just built, not mentioned by support on the forums yet at all, and I gave that a shot - I HUGELY appreciate that, after both of us got pretty snippy they turned a complete 540 and looped me in a bit on the process of getting this to work - however, my last response from them was two weeks ago. My familiarity with this type of programming is limited, as I have only some minor experience in basic coding as it applies to video game development, however; if the adapter's firmware can address the type of signal it sends (which makes sense, as it's an active adapter doing something new, translating DP>HDMI2 hot down the line) it seems to make sense they could produce a "vizio firmware" that specifically forces a signal the vizio will understand, 4:0:0 8bpp, and via EDID data reports ONLY THAT SIGNAL. even if this firmware was only produced to customers via support to prevent it's misuse, it'd flip my feelings on this whole situation to a perfect review. I will stress though that contacting support was pretty excellent. Eventually. Even though they didn't fix my problem, a real person did work really hard with me, and probably some poor tech who also had to suffer my typed out rage. But still, if you have a vizio TV, I would make ABSOLUTELY SURE someone with your IDENTICAL CONFIGURATION (GPU, SAME MODEL of TV) has gotten it working, or you love preparing returns to send out.
