Refresh Rate Issues NVIDIA

I have been having an issue where in display settings I have the option to turn my refresh rate up to 75hz, which is correct because on Windows I use that refresh rate.  However, when I turn up the refresh rate from 60 to 75hz, my monitor will give me a no signal message. 

I am using a GTX 1080 with the 'nvidia 515.65.01-2' driver.

Go ahead and let me know which logs need to be posted, and I'll get them over.

for edid in /sys/class/drm/card*/edid; do echo $edid; edid-decode < $edid; done

and also

xrandr -q

The result I get is:

xrandr -q

The result is:

Re: Refresh Rate Issues NVIDIA

Seems you have two monitors connected to HDMI and DisplayPort. For which one do you want to turn on 75 Hz? Are both working with 75 Hz on Windows?

Does

xrandr --output HDMI-0 --refresh 75

lose the signal?

an issue where in display settings

What is "display settings" exactly? (I guess something from your desktop environment?)
Can you successfully control the refresh rate with "nvidia-settings"?

I am not sure which one, but it does work in windows, and it did work on archlinux before I changed my graphics card and subsequently the drivers.

The xrandr command didn't appear to change anything... also yes the display settings are just what comes with KDE when you right click the desktop.  I haven't tried using nvidia-settings.

Re: Refresh Rate Issues NVIDIA

Please avoid full quotes.
After running

xrandr --output HDMI-0 --refresh 75

, what's the output of

xrandr -q

and what does the monitors OSD say about the refresh rate?

Re: Refresh Rate Issues NVIDIA

Here is the result of xrandr -q after running the first command.

Re: Refresh Rate Issues NVIDIA

HDMI-0 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 476mm x 268mm
   1920x1080     74.97 +  60.00*   59.94    50.00    60.00    50.04  

That would indicate that despite 75Hz being preferred you cannot even effectively toggle - but you also didn't get any error message from xrandr???

Install openbox and run an openbox session instead of KDE, see whether you can have/change to 75Hz there (do NOT run systemsettings, you can use nvidia-settings or "xrandr --output HDMI-0 --refresh 75")
I suspect that some process tries to be extra-clever here and monitors and aligns the refresh rates.
Can you set  HDMI-0 to 75Hz (in KDE) when you remove the other output on DP-3 ?

Ah yes, even without the other monitor in the picture, only the 75hz plugged in, there is still no signal.  I highly doubt it is a KDE problem because it worked correctly in this configuration before.  Namely after I changed my NVIDIA drivers from the legacy ones to the mainline drivers when I upgraded my graphics card.  This is when the problem began.
