Can't run monitor in 4K at 60 Hz with new NVidia drivers

[branskyj]

Hi all,

I have a Windows 10 Pro, GTX 670 4GB and Philips BDM4065UC 4K monitor here and have been having this problem forever- I can run it in 4K at 60Hz but only with very old NVidia drivers (352.84). Anything newer than that would cause the monitor to only run at 29 Hz or 30HZ, the option for 60Hz disappears as soon as I install newer driver.

I have checked both with NVidia Control Panel and the integrated Windows way through right click +Display settings and indeed 60Hz is no longer available when new drivers get installed.

Now, I am absolutely sure my DP cable is capable in supporting 60Hz, like I said drivers 352.84 run wonderfully in 60Hz. I've also made sure that the monitor is set to DisplayPort 1.2 in the OSD menu and not DisplayPort 1.1.

Usually I wouldn't make a big deal out of this, in fact up until recently I was running my PC with the old 352.84 drivers. The problem is that 1-2 weeks ago my video drivers started getting automatic updates and no matter what I did to prevent these automatic updates they continued. I went through GeForce Experience and made sure that "Automatically download driver updates..." and "Notify me when a GeForce driver update is available" are both unchecked.
I also made sure Windows doesn't update the drivers itself via System properties/ Device Installation Settings/ No

Running my monitor at 30Hz results in obvious mouse cursor lag, super annoying. Not to mention that every time I get new video drivers installed my icons on screen get re-arranged.

Does anybody know why can't I run new NVidia drivers with my current setup at 60Hz? I realise my GTX 670 is rather old, could that be the problem? Could it be that NVidia no longer update their drivers so that they run at 60Hz with older hardware?

Any help would be much appreciated.
Thank you.

It seems this monitor in particular has some issues with running at 4K 60Hz with display port. Here is a thread over at Geforce forums about it in fact.

Have you tried updating the firmware if they have one available? I doubt it's the drivers though, as other people in that thread with different GPUs (including AMD) have the same issue.

It may be that this particular driver you're using doesn't trigger the problem, even though the problem still exists.

Thanks for the helpful link, will definitely check it out.

Though I think I found out what the problem was- I forgot to mention I have a dual monitor setup (2560x1440 via DVI and 4K via DP)and as it appears running both at 60Hz is just too much for my ageing GTX 670. Once I unhook the 2560x1440 and just remain with the 4K monitor I can run it at 60Hz even with the latest NVidia drivers. I will upgrade my graphics card soon, that was my plan anyway and that will help.

Much appreciated, Carfax83.

I had that same monitor. It's very picky about DisplayPort cables. The cable that always worked with it was the Accell B142C-007B UltraAV. The other two cables I had would either not produce video or only work with the monitor set to DisplayPort 1.1.
