Is anyone else having problems with custom resolutions on the latest Intel drivers for 6th Gen and later?

Whenever I set a custom resolution using CRU or Intel Graphics Control Panel / Command Center after the monitor has gone to sleep, and just at the point it is about to wake up I get a dxgkrnl crash recorded and the monitor stays blank.

I believe CRU and Intel tools use different registry settings, so it's odd there's a problem with both sets of tools.

It's quite repeatable and as soon as the custom resolution is removed the problem goes away.

Any workarounds?

Because that's not how it works. Your monitor can't handle FreeSync. Why is that so hard to understand? Every symptom you've described is the monitor not being able to handle FreeSync. Older drivers didn't have FreeSync active on the *desktop*, which is separate from games. Try the G-SYNC pendulum demo to see if it's actually working: https://www.nvidia.com/coolstuff/demos#!/g-sync

The FreeSync data block in CRU is meant for editing the HDMI FreeSync range, not for adding FreeSync to non-FreeSync monitors. A few non-FreeSync monitors can handle FreeSync, but the vast majority do not.

Oh now I get it, sorry. So even v17 doesnt work in games, I tried it only on desktop. Ok, thanks for explanation.

Hey all, first-time poster ( i think). Thanks, toasty for a great tool!

I'm trying to overclock my 4K TV to higher frame rates. ATM i have 1080p working at 74hz from the usual 60hz. The problem is I had to increase the TMDS from 360 to 400 to get this. Is this a good idea, to manually increase it? What does the limit depend on?

I run the patcher and it did find and patch values. For referecene i have:

A 1070 - which is HDMI 2.0b compliant using a HDMI 2.0b cable.

I haven't seen NVIDIA's driver use the TMDS limit, and you shouldn't have to change it anyway because 1080p @ 74 Hz is nowhere near 400 MHz pixel clock. You shouldn't need the patcher with HDMI either.

That sounds like a driver bug that you should report to Intel support, especially since it also affects custom resolutions through their own control panel.

Hi.
I have some problems with nvidia surround.
I got two monitors from ali

and laptop MSI GT72VR with 1 mini Displayport and 1 HDMI. Both monitors connected via these ports.

I tried to create some custom resolutions with different settings in CRU, but it still not working with 3 displays.
Can i do something to make this work?

What resolutions are you trying to add? Do the resolutions work without Surround?

I tried to copy resolution parameters from additional monitors to main and on the contrary. I made it in CRU and in Nvidia control panel. Nothing works properly... The main laptop's monitor doesn't take part in array.

https://imgur.com/a/p4J6Vei - parameters at first picture. only 1920*1080 on each monitor but with 50-60Hz, different front porches, sync width etc...

Oh, I misunderstood. If you're trying to make the laptop screen work with Surround, I don't think the driver will allow that. NVIDIA says "Surround is not designed to work with an external monitor and laptop display."
