I have the Benq 27" 1440p 144hz on display port and random DVI 1200p 60hz monitor on HDMI port ( i have bought a dp to dvi wire).

GPU is 4070. Seems that i have fixed the Benq problem by removing tv resolutions on all 3 monitors CRU showed.
I can connect the second monitor, all works fine, but if i reboot, i get black screen, not just black screen, i always get the PC crash. I can only reboot and boot in safe mode.
But if i boot with only the Benq on DP i can boot ok.

This is an NVIDIA driver bug and should be reported to them. The black screen is the driver crashing, not a resolution issue as you've figured out.

I haven't had success at doing the same at native resolution. I didn't set up the parameters for 1080p, it just works and not from the graphics driver because there are no custom resolutions defined. My assumption is that they were already defined in the blocks.

Is it possible for me to reach 23.976 Hz at 2048x1152 instead of 1920x1080?

The monitor might only allow lower refresh rates for TV resolutions like 1920x1080 to support 24/25/30 Hz, so it might not be possible at the native resolution.

Using CRU I can see this:

It's possible to do any configuration for my TV to support 1440p?

That means the resolution is being scaled by the GPU. If your TV can display 1440p, then you can add it as a detailed resolution using CRU, and it will be sent to the TV if GPU scaling is disabled.

I've tried but not working... the image becomes small and there is a text in one side of the screen that says "Resolution not supported"...

GPU/TV Scaling is not active

TV native resolution is 1080p... any solution or it's impossible to get that resolution working?

Thanks for answering.

If the TV doesn't support 1440p, then you'll have to use GPU scaling.

Thank you Toasty for your work and your time to deal with us, very much.


When i reboot with 2 monitor installed, it is obviously a driver crash cause it even turn off the keyboard. The PC completely freeze.

If i unplug the 60hz monitor from hdmi port it will boot no problem.

Do you think we could find a fix? Should i try older drivers?

I bought a dp-dvi wire to try to connect the 60hz monitor to dp instead of hdmi.

Hi,

I have multiple displays and when I turn one or more of them off, Windows will notice this and will change the monitor settings to exclude this monitor from the layout. This causes all windows to be moved and having to put them back when I turn the screen back on is very annoying.

So what I want is that Windows doesn't notice when one of the monitors turns off. I did some googling and it seems that maybe if the monitors' EDIDs are fixed, Windows won't notice when they're off. So in CRU I exported the monitor settings and then imported them again in order to make them fixed. Unfortunately, Windows still notices as soon as a monitor gets disconnected.

The monitors are connected through DisplayPort, but I've seen similar issues when they were connected through HDMI. GPU is an Nvidia 4080.

Maybe what I'm trying isn't possible or maybe I'm doing it wrong. Any help would be appreciated.

I don't know what triggers the bug because not everyone runs into the problem. It's not anything in the EDID itself because just the presence of an EDID override with no changes will still trigger the problem. Sometimes a different connection can work around the problem. This has been an issue since around 471.11 or 471.41, but I don't know if people have been reporting the problem to NVIDIA. You would have to try 466.77, which probably won't support the 4070, and Windows has a habit of automatically upgrading older drivers.

The only thing that caught my attention is you mentioned Armoury Crate. Try uninstalling that and see if that makes any difference. I still think this is an NVIDIA driver bug because only NVIDIA users have reported this issue.

CRU does not emulate a monitor connection, so that won't work. The problem is DisplayPort disconnects when the monitor is turned off, and if Windows didn't move the windows from the disconnected monitor, there would be no way to access the windows. Windows has no way of knowing the monitor is still connected and doesn't offer a way to leave windows on disconnected monitors. The real solution would be to allow sleeping individual monitors, which would keep them connected but with the screen turned off, but Windows only seems to offer power saving for all monitors at once.

Hey, i am using streamlabs preview on second fake screen which is emulated by hdmi dummy. This is necessary for me to run some kind of scripts that i use. I dont need to see this preview but my ahk need this in that position.
My main monitor - real one is working On 2k@144hz and basicly this dummy can work up to 4k@60hz. Its not good at this 60hz since i feel freezes while playing On 60 or even 120hz. It goes back to smooth and nice when i set custom resolution in nVidia geforce to 2k@144hz for this dummy but after restart.exe or just reboot my computer is not responding at all. It can boot Windows but there is no login screen. Caps lock not reacting. Then i have to unplug dummy, restart pc, reset all, plug dummy then set my custom resolution again. And it works like it should. Untill some kind of restart/ reboot. Any clue how to solve it to not brother with this pain in the ass job with plugout, reset all plug in and set again every reboot?


"This is an NVIDIA driver bug and should be reported to them. The black screen is the driver crashing, not a resolution issue as you've figured out."
it's same problem in my case?

I can actually sleep one monitor by switching it to a disconnected input. However, when it wakes up again, it disconnects and reconnects, which still moves all windows around. This is also an issue I have when waking up all monitor in Windows 10, monitors reconnect, but windows are moved. In Win11 I can also hear the monitors reconnecting, but the windows stay in the same place. Apparently Microsoft made a fix for that. Still annoying I can't turn a monitor off without the windows moving though.
