If you have connected the PC to the monitor via HDMI you would only get 30Hz; however if connected to the DP, then please go in the oSD and change the setting to 1.2 instead of the default setting of 1.1
This should enable you to get 60Hz

I can see 2 places to make sure you are 60hz after you ensure you are on DP 1.2.

1)In the Nvidia display panel.
2)If you go to your Windows Desktop>rt-click>screen rez>advanced>Monitor tab>Select 60hz in the drop down.

I did the Windows adjust while the Nvidia control panel was open and didn't see the change. Made the change in Windows, opened Nvidia and saw it.

Alright guys!! I SOLVED THIS!! Finally!!!
After hours of trying I figured out how to get your 4k tv/monitor to 60hz -

MAKE SURE You start by having your old monitor also connected to your pc and have them on extended display - so that the 4k and your old monitor is an extension just in case the new 4k tv goes black screen. This means you need 2 hdmi cables. 1 normal hdmi cable for your old monitor and a new HDMI 2.0 cable otherwise known to be 17.5 Gbps+ cable of 4k. You should now have 2 monitors showing the same the screen or an extension of the screen.
All the settings that need to be changed should be done on your old monitor - by this I mean to say when you right click on the desktop and go to nvidia control panel - or even right click and go to screen resolution, these windows should be showing on your old monitor in case your 4k tv decides to go to black screen.

First you must use your remote and rename your 4k tv by pressing "source", hold your cursor on the HDMI port you wish to use (HDMI/DVI port 2 in my case) and rename it to "DVI PC" (not PC only) - even if the HDMI port seems greyed out. Then press "menu" on your remote and go to "picture" then scroll down to "picture options" then make sure that the HDMI UHD Color is ON. (Make sure your hdmi cable in not inside the 4k so it can restart itself.) After this you should plug your HDMI from your graphics card (970 GTX in my case) into your HDMI/DVI port 2 in your 4k tv.

Now, simply right click on your desktop and go to "Screen Resolution", now make sure to select the 4k tv in "Display" and change the "Resolution" to 3840x2160, and now go to "Advanced settings" (highlighted in blue), go to the "Monitor" tab, and change the refresh rate to 60 Hz and press Apply and OK.

Press "source" on your TV remote and select the HDMI/DVI (DVI PC) source. Now your TV should display the 3840x2160@60Hz instead of the 3840x2160@30Hz. The final step would be to right click on your desktop and go to "Nvidia Control Panel", then in the Display section click on "Set up multiple displays" and uncheck the box that is associated to your old monitor and click Apply. Enjoy.

(P.S By renaming your TV HDMI Port you are now able to change your previously greyed "Game Mode" setting to ON in your TV (this is under the "menu", "settings", "general" area). If you are a gamer like me and don't really mind a little degredation in quality for a better FPS then you would like this, otherwise leave it OFF.

This should work for everyone, but bear in mind that I am using a Samsung UHD 40" TV, so your settings locations in your other TVs may vary.

[Please don't regard this as a complete solution since I tried my best for you only, if you have any further questions don't hesitate to post]

Hi, I know it has been two months but I just got the same monitor and was having the same issue. The solution is just to turn on the Displayport 1.2 in the monitors config since it comes in 1.1 mode when you buy it.

Check this video out: https://www.youtube.com/watch?v=hCGbn86AuDo

After that it will display in the Nvidia Control Painel the new resolution under the "PC Resolutions (native)" not the "Ultra HD" resolutions, just scroll down in the list of resolutions until you find the 3840x2160 (native) info with 60hz. Hope this helps.

I just bought 2 PA328Q's at almost $1200.00 a piece and a GForce GTX 980 Ti. Soo... after spending a bunch of money to get the best looking picture possible on two displays im a little confused as to why when i go into the NVIDIA Control Panel my first display which is hooked up via HDMI allows me to select Ultra HD, HD, SD and then 4k x 2k, 3840 x 2160 (native) with a refresh rate of 60Hz. When i click on my second monitor which is hooked to my display port under the same section with the same resolution selected only lets me choose a refresh rate of 29Hz? I have the display port mode on both monitors set to 1.2.

Now to make things a tad more confusing (for me) i can keep my HDMI monitor at 60Hz and set the display port monitor to a "PC" resolution of 3840 x 2160 (native) and it lets me select 60Hz? So why can't that monitor be on the Ultra HD, HD, SD and then 4k x 2k, 3840 x 2160 (native) as well?

Also when both are set to 60Hz it seems like text on some menus has a fuzzy rainbow color on it which is just beyond me.

Can anyone tell me what im doing wrong here or what i should do to have optimal display resolution on both monitors?

Thanks in advance
