I was using DisplayCAL to make some high quality monitor/tv profiles but it started fritzing out worse and worse.
For a couple days, zero issues.
Then it would say it can’t load a profile after it finished creating it after I had created a few in a row.
Then the next day it would also start the screen flashing black and GPU drivers would bomb out so badly nvidia disappeared from my system, but a reboot would make it fine.
Then an hour later it started being that a reboot would not help and had to power down and up.
Then it started happened not after creating a few profiles but every single time I’d make a second profile.
But then it is now such a mess that even re-powerip up fixes nothing and the second I log into windows the whole graphics system crashes out.
It now has my Windows 10 so scrambled that virtually any monitor profile created by any software now instantly crashes out my nvidia drivers so badly the second it is selected that makes Windows color management thing my display is a printer! and the display becomes lo-res and with no hardware accel and I’m currently stuck with W10 with almost unusable color management.
As soon as I have anything more advanved than a pure matric gamma 2.4 profile created artificially in Photoshop is selected in Windows color management (or even if any other sort of profile is so much as even stored in the Windows->System32-?spool->drivers->color directory!, or alternately have DisplayCAL try to load any monitor profile of any type at all, the screen starts flashing black more and more and then within a few seconds Nvidia drievers bomb out totally and disappear and even any open disc folders disappear and system crashes back to primitive display. Profiles that worked for ages just crash it all out now.
Removing DisplayCAL, re-installing all sorts of nvidia drivers, so far nothing works.
I can’t use a monitor profile without the system just instantly crashing out.
Struggling to figure out how to fix whatever the heck some combo of DisplayCAL/Argyl or W10 did my W10 system.
Anyone have a clue how to fix things when DisplayCAL (or maybe Argyll driven by that did it or maybe W10 itself destroyed itself fed some fancier profiles) has screwed up windows 10 monitor profile handling??
Maybe some bad entry is stuck somewhere in the registry, I don’t know what.
It is pretty crazy that something as seemingly basic as monitor profiling software could somehow do something that ends up making W10 so damaged.
I was testing out creating and comparing 1xgamma+matrix, 1xcurve+matrix, 3xcurve+matrix and XYZ LUT+matrix profiles.
Both my monitor and tv have internal calibration. Speaking of which, at one point, oddly, DisplayCAL kept bringing up this window about warning should it use current display curves do you want linear, linear+current and stored in profile, maybe not so long after it was popping up that stuff it started with the issues growing worse and worse. I also think I had it set to not touch graphics card LUT since my displays have internal calibration.
I uninstalled and re-installed DisplayCAL, unisalled DisplayCAL and deleted it’s AppData folder and left it uninistalled, tried clean installs of game ready and pro nvidia drivers, most recent, from a few weeks ago, an old 400.something driver, trying all sorts of combos of the above, nothing fixes anything.
Total disaster, can’t use it to make needed profiles but far worse can’t even sue any profiles made by any software now. Can not edit any images or video in wide gamut mode now at all (as the best I can get working is a hyper basic REC709 primaries matrix + Gamma 2.4 signature ultra basic profile created artificially in Photoshop, any other monitor profile at all totally crashes my system out now no matter what made or what type it is and whether Windows or DisplayCAL loads it). System is totally trashed.
I managed to coax it to use a DELL DUCS i1profiler profile for wide gamut mode on my monitor by picking that then as soon as it started flashing baclk, quickly logging out before it crashed out. Now that works…. partly. On each reboot it works and basically so long as I don’t re-start the display once logged in it is OK. But if I turn off the monitor and turn it back on it does the whole mess and crashes out and has to be rebooted.
For my TV it is even worse, I can’t even use my TV with my PC at all, it flashes and nvidia crashes out before I even get to log in.
I also think I had it set to not touch graphics card LUT since my displays have internal calibration.
There is a high chance that low cost HW calibration solutions do not work as intended and you’ll need GPU calibration to fix grey and/or white.
So… measure it, If is behaving OK you shoudl use DisplayCAL only for verification and/or LUT3D creation with XYZLUT profiling without GPU calibration (linear calibration curves)I uninstalled and re-installed DisplayCAL, unisalled DisplayCAL and deleted it’s AppData folder and left it uninistalled, tried clean installs of game ready and pro nvidia drivers, most recent, from a few weeks ago, an old 400.something driver, trying all sorts of combos of the above, nothing fixes anything.

Looks like a windows + nvidia driver issue.
Did you use “DDU” for full clean uninstall of rogue drivers?

Thanks, did just try that! I was somewhat doubting that it would work, but it did seem to restore the system! Thanks so much! Didn’t get to test it with loading profiles yet, but at least it doesn’t crash the video card out on log-in, screen off/on, etc. so hopefully it will work. If so will make a backup and then try with DisplayCAL again and hope it works.
