UPDATE with fix to the blackscreen problem via hdmi 2.0 with 4k on pc.
Wow... I found the fix..
Finally after over a month of dealing with completely incompetent tech support, EVGA saved my ass.
Erin W, (EVGA suport.)
customer service rep I believe.
This guy is a God send.
I do not know him and this is not a joke.
I have been dealing with Nvidia level 2 and Samsung level 2 and 3 support for well over a month now,
because my 4k Samsung was not working in 4k. It would blackscreen on me when I went into any 4k res.
I have spent hours and hours and hours dealing with this.
I have pulled my hair out and bled inside this computer over this..
After going through owning my gtx 680s and getting no solution then upgrading to the 9 series and still getting no help
At the end of my rope. When I had finally lost all hope and given up.
Swear to God I was feeling defeated like this, trapped with zero hope and no help: Anyway,
I got an email from EVGA so I decided to call them up.
We start running through the basics, try one card at a time etc.
Then Erin W tells me that maybe I need to enable UHD colors..
UHD colors? huh? ?!
Turns out you have to actually physically enable it for each HDMI port.
NEVER,
not even ONCE,
from dealing with all these people who call themselves "professionals" in tech support, did ONE single person even hint at such a thing.
My problem is solved and EVGA has a lifelong buyer now. My mobos, my gpus, hell, if I need a blood transfusion, I'm getting it from EVGA!
You guys Freaking rock!
Now I feel more like this:
IMPORTANT UPDATE:
Been talking with Manuel at Nvdia and he assures us that in this "NEXT driver update" they will support 4k res for sli systems via HDMI 1.4, with their current work around.
I can deal with that.
He also clarified that your TV or monitor will need to support Y'CbCr 4:2:0 over HDMI 1.4 at 4K.
So make sure of that.
but hey, the 9 series came out and it supports HDMI 2.0.
Just goes to show they support their new paying customers, while leaving the last generation in the dust.
Original post:
Just a heads up. After spending thousands of dollars building my system to be 4k capable and Nvidia recommending going sli for 4k..
Turn out sli doesn't even work in 4k..
Nvidia said they had work around that made it work but NOT THAT IT DID NOT SUPPORT SLI.
Yea, as you can imagine I am pretty let down by that.
They recommend it here: https://developer.nvidia.com/4k-ultra-high-resolution-development
I quote: "NVIDIA recommends GTX 780 SLI or better."
Well guess what? sli doesn't even work in 4k unless you are using display port 1.2.
I tried it. The forums are filled with people complaining about it and I am one of them.
This is one of several topics:
https://forums.geforce.com/default/topic/727637/sli/4k-sli-issue/
I try to enable my sli in 4k and what I get is a flashing, green screen or crazy artifacting.
Yes I always expect next gen things to have teething problems but when Nvidia recommends sli for 4k..
It should work and it doesn't.
So fyi, don't go sli for 4k, save your money, unless it has display port 1.2.
"which generally only comes in monitors"
They sound like the 6 and 7 series may not even support hdmi2.0 anyway.
If they do, it may completely screw you into some 30hz refresh rate OR down sample the 4k quality, with some "chromatic thingamajig subsampling"
I read about on nvidia, that is buried in topics of BS, to make it work.
So it won't be TRUE 4k anyway.
I got my hdmi 2.0 cables in the mail yesterday and that STILL doesn't fix it..
There is tons of misleading info out there, that's just marketing and nvidia trying to sell more gpus at the cost of the consumer being the test subject.
So don't buy into the hype, new gpus and false advertising like I did for 4k via HDMI in SLI.
Wait until it actually works.
