For your info. My 1080Ti able to work in 10bit colour mode in 10.13.2 (17C88) on my Samsung CHG90
Cool monitor! ;-)
Thanks for the info.I guess it's an issue with my monitor.
Despite of the description it's not a real 10 Bit monitor: https://www.asus.com/Commercial-Monitors/PB279Q/

Just to mention, I had same color output in 10.13 if both GTX 980 and GT 120 were in Mac. As soon as i removed 120 everything was back to normal.
But this is totally unrelated to SwitchResX and 10 Bit option.
Can some one tell me of this card is compatible with a MacPro4,1 firmware flashed to 5,1 running MacOS 10.13.2.

Not sure, most likely can work AFTER Nvidia Web Driver installed and selected.
But be careful that the feedback on using Maxwell / Pascal GPU is very inconsistent. Some users like me has flawless experience, and some other feedback the bug / glitches make their card effectively completely useless.
I still can't figure out what's the key element to make such a big difference, but up to this moment, I personally suggest better to go for reference design PCB if you want to run these kind of GPU.
Thanks for the reply, i'm still confused on what card i should use ? so maybe i should try an Nvidia GTX 680? I'm not sure what you mean by reference design PCB ?
For each GPU, Nvidia will design a PCB for it, and the one that Nvidia sell to public is called the reference design PCB.
Some after market graphic card even use the same GPU, but may put it on their own customised PCB. e.g.
This is the reference PCB of the 1080Ti, as you can see, Nvidia's name and logo on it.
This is the PNY 1080Ti XLR8's PCB, this PCB is NOT manufacture by Nvidia but by a 3rd party, however, it looks the same as the reference PCB.
And this is also a 1080Ti's PCB, but it's from the MSI Lightning Z model. As you can see, it looks very different then the reference one, no matter the port layout (an extra DVI port), power supplying ports (3x8 pin vs 6+8), power managements (14 phases vs 7 phases), etc, all different.
They are all 1080Ti. However, I highly suspect the Nvidia web driver never been tested on the non reference on (in this case, the MSI one). Therefore, it's hard to tell if the card can work properly under MacOS.
If you can use the GTX680 rather than 750Ti or 1050, and no particular reason need these 2 cards. Of course go for GTX680 is better in general on a Mac. The GTX680 is natively supported by the OS, Nvidia Web Driver can be used as backup. Also, the reference card can be easily flashed to show boot screen properly. That's still the most handy latest Nvidia option on cMP.

I just ordered a GTX680 that's flashed on e-bay. And an AOC 40" 4K curved monitor from Amazon Prime. I was all happy. Imagine that a day after the AOC shipped, it showed "delivered" on Amazon; I didn't have it of course. After hours on the phone it turned out that the 3rd party vendor had told UPS to return the monitor to Amazon. It was delivered alright, but back to Amazon dock - in Kansas? My only choice was a refund and to re-order it -- at a much higher price.
After literally more hours on the phone they told me to order it for delivery in 2 days at the higher price, and they will refund the difference. We'll see.

The Gigabyte GTX 750 Ti will not play iTunes DRM movies. And it has a 6 pin connector, i.e it will not run from PCI-E power only. I had this card.
Safest way is to buy an EVGA GTX 750 Ti, most recommended.

You could have saved a load of money if you bought a vanilla PC GTX680 & then flashed it yourself using the info on this forum. The vendors of flashed cards charge a very high premium for a few minutes work.
Thank you @nigelbb for your suggestion. I was in a hurry, there weren't a lot of GTX680s available, I wasn't sure which is a safe/compatible image, there were some unkind replies to people who asked questions, AND the vendor (macmotive) IMHO didn't overcharge at $219 shipped with two power cables and 30 day return/warranty/exchange.
In any case I have nvFlash 5.416.0 and a 218,112 byte gtx68mac.bin from 4/11/2013. Is that still the right one for a 2GB EVGA? For other 680s? For 4GB? How to locate the best BIOS for other cards?
@William Payne As to Amazon, no they didn't deliver to the wrong address. The "3rd party" vendor had the shipment intercepted by UPS and sent ... back to Amazon. Then he offered it again, but at a higher price. Amazon agreed to cover the difference - from a different vendor.

I just found where the possible problem is. If I switch to HiDPI, then I get exactly the same colour issue as you do. Since your monitor is a 4K monitor. So I suspect you are running some HiDPI resolution. May you try if you run at native 4K resolution, will the 10bit colour able to display correctly?
FYI - there’s currently a bug with the CUDA driver and OS X Native driver being unrecognized (when selected via the NVIDIA Web Driver Preference Pane). Some issues I’ve run into lately are because of this. Reported to NVIDIA and they’re working on a fix.
This CUDA "update required" is what I asked NVIDIA about. Expect a fix in one of the next versions. mac OS 10.13.2 (17C88) with CUDA Driver Version 387.99 and NVIDIA Web Driver 378.10.10.10.25.102. Only happens when booting with the native OS X Default Graphics Driver.

Unfortunately its a Windows only test but I finally found a test to check for 10 bit colour capability that is a little more easier to understand then a gradient in photoshop.

[doublepost=1513324278][/doublepost]Great article on 10 bit colour and how it works regarding the Geforce cards vs quadro cards.

[doublepost=1513324964][/doublepost]In that image science article there is actually a test down the page to see 10 bit in photoshop, I tested it on an 8 bit display and if I had use 30 bit display in photoshop turned off you would get banding all over the show, if use 30 bit display was turned on even on my 8 bit display the banding would decrease to near unnoticeable so it must be doing some type of dithering effect when using the 30 bit display setting on an 8 bit monitor.

The e-bay flashed 680 I got works ok. There's boot screen over HDMI, not DP. Is that common?
FWIW, the AOC C4008VU8 40” Curved LED Monitor is so far quite good. It has 2 DP 1.2 (60Hz), 1 HDMI 1.4, 1 HDMI 2.0 and VGA in. I think 43" might be a better size for using 4k with one's head a little further away than 12-18", but this at least is a bona fide monitor rather than a TV. Great at 60Hz, but I'm surprised at how usable it is at 30Hz over HDMI. Amazon refunded the price difference when they didn't deliver and I had to buy it at a higher price.

For a properly flashed card, I don't think so.

oops. Well, I diplomatically asked the dude "what I need to do" to get a boot screen over DP. We'll see what he advises. But how in Heaven's name do you flash a card improperly so it partly works?
But that's better than the 2Gig 750ti I got also on e-bay. Now I should add that I've had excellent luck on e-bay for years and years. And this 750ti card was cheap. I've had a few items that weren't up to my standards, but that's because I have indecently high expectations. And that was only like 1% of my e-bay adventures, you know, like a Swiss Army Knife lookalike that someone forgot to put blades on.
But the 750ti was a let down, starting with not being able to match up the photos with any 750ti known to Man, but we live in such times as we live in, between the miners and the rest, so I figured we'll see. Installing it under Windows 7 was bizarre. Stupid Windows. It kept insisting to install AMD drivers. So, seeing as we live in such times .. I let it. And lo and behold, it ran, and said it was an R9-200 - of some sort. Hey, it matches the R9-270 and 270x and 280 and many many other photos on MSI's "catalog". It even runs in 4K at 60Hz. With only occasional very thin wispy white lines and periodic senior moments in which it forgets all about sync and the monitor goes "cluck". At 30Hz it runs dandy. And again I learned that all these nitpicking gamers are just crazy, nothing wrong with running Logic at 30Hz.
Now I'm stuck wondering what to do. A guy who sells all kinds of garage leftovers and told me, when I asked about 60hz 4K that I should call Geek Squad as he "doesn't offer tech support", is he to blame? Or is MSI for slapping any chips it can get onto "gamer specials" that all look alike? And if it does 4k OK at 30Hz, at $69 plus $9 shipping, should I just keep it? Flash it? Start up a Bitcoin Mine? Or maybe call Geek Squad? Anybody got the number?

im also a little bit pissed about this update sessions...im really thinking about to sell the gtx980 and stick the titan back...the performance is quite the same and a few more watts will not kill me...

If your original Titan can work OOTB, and your workflow can’t benefit from the GTX980 in general. Then go back may make more sense. Even OS update is not that frequent, and we are not forced to update. But no need to worry about black screen etc still make life a bit easier.
