Hi all,

I am currently running on GTX670 and Philips BDM4065UC 40" 4K monitor. Windows 10 64bit. My drivers are 353.30 which is pretty old. The cable I use is Display Port and I've set up my monitor OSD to DisplayPort 1.2. Everything runs fine at 60Hz.

For a while I've been trying to update my drivers, I always get the certified ones but every time I install them my video connection get downgraded from 60Hz to 30Hz during the instalation. I then restart the PC and when I go to my monitor settings I no longer see 60Hz listed as an option. I only see 30Hz and 29Hz. The same happens when I go to NVidia Control Panel.

I've tried 6-7 times for the past 1 year and every time the same.
I normally wouldn't care but since some of the drivers offer improved performance in various games I wanted to give it a go.

Any tips?

Thank you.
 
Have you tried to unplug your monitor and plug it back in again and see if the options changes, it fixed my issues with missing 60
 
I wouldn't put the effort into trying to get new nvidia drivers working with such an old card, nvidia are known to break older support in their rush to promote support for this months must have game.
 
How Strange,

As when I switch it off and on again then go into monitor options I can change it to 60 if its reverted back to 30.

Can you try a different display port cable ?
 
Sorry guys, I thought the thread was dead :)

1. The monitor is absolutely set to DP 1.2 in the OSD
2. I don't have any other DP cable but then again the current one works fine at 60Hz, just with the old drivers, not the new ones.

As for the other suggestions- I will try them this weekend, even though last time I tried my sound got messed up and Windows started using the monitor speakers instead of the other ones.
I will be upgrading my graphics card soon anyway. Maybe that will fix the problem.

Thanks for your help and will post again soon.
 
hi m8, ok i had this problem when i had an older driver but not had it for a while, i noticed that in the resolution section of nvidia control panel the monitor was set to its native resolution under the header of ultra hd,hd,sd, but if i scrolled down a bit there was another section headed " pc " under the pc header there was again the native resolution which then worked at 60 hz,

Click to expand...

I had this problem also... my system on reboot was detecting my 4K monitor (Iiyama) as a TV (Ultra HD, HD, SD) as opposed to "PC" 3840 x 2160 in Nvidia control panel. 30Hz is frustrating.

In the end, I think I installed the monitor "driver" (profile) from the manufacturers site.
 
Hey guys,
sorry, I thought the thread was dead...
Thank you for the input. Unfortunately under PC section in NVidia Control Panel there was no 3840x2160 at all.
I also downloaded the .inf from Philips's website, installed it but that did not help with getting 3840x2160 at 60Hz.
What I did manage to do was to set a custom resolution of 3840x2160 at 51Hz. It's not butter smooth, I can feel a certain lag in the mouse movement but it's better than 30Hz :)

Cheers.
