Multiple monitor support
Originally reported by: Sparx (Bitbucket: Sparx10, GitHub: Sparx10)
I usually have a game on one monitor that I would like to keep in regular color, but then on the other monitor I have some horribly bright white applications, like a web browser, file explorer, or Skype.
Having the ability to invert only one monitor would be really nice. Basically just setting different inversion matrices for each monitor.

Original comment by Sparx (Bitbucket: Sparx10, GitHub: Sparx10):
That's alright. I was hoping it would be a rather quick implementation to tide me over while I work on a fork of this shortly in the future, but I suppose now I'll just have more motivation to get my forked version done more quickly.
Original comment by Melvyn Laïly (Bitbucket: yaurthek, GitHub: Unknown):
Unfortunately that's not possible with the Windows Magnifier API NegativeScreen 2.* uses. It was possible with NegativeScreen 1 though (but NegativeScreen 1 was a bit more buggy and slow)...
But you are not the first one to ask for something like this. As I said before, I might release a future version with a mixed mode, using the fast API when in full-screen mode, and using the old API to allow enabling different matrices on different monitors...
it's quite a lot of work though, and I haven't been able to work much on this project lately. Sorry...
I would also find this feature very useful. I often have my primary monitor running an already dark themed editor, and would like to select all other monitors to toggle the color on, but leave the primary monitor alone from toggling.
I also have a monitor that's recently decided to default to showing the "negative" color of what its being driven with from the video card. NegativeScreen actually fixes the issue by flipping the colors back to their normal values. Thanks for providing a workaround fix for my monitor! Having the ability to toggle the colors in the opposite mode of the other monitors would also be a nice enhancement.
Thanks for your feedback everyone. Still no progress on this feature request, but I'd like to mention I released an unofficial version a (long) while ago that got lost in the comments of my website.

I've been using "NegativeScreen-custom-multi-monitor.exe" to invert the colors on just one of my monitors in my six-monitor setup. I use this monitor to connect to a "crash cart" adapter to use with a Privileged Access Workstation that I can't alter the colors on, so this tool has been great in toning down the colors for me to use throughout the day. I'm not noticing any video performance issues with it, but then again I'm only using it for non-gaming tasks and am running it with a Radeon RX 590.
My only issue with the "custom" version of the tool right now is that by default when it launches, it inverts the colors of all six monitors and I have to manually unselect the first five monitors from the context menu each time I reboot.
Would you mind adding a feature that would modify the 'OverlayManager' of "NegativeScreen-custom-multi-monitor.exe" to have the 'ToolStripMenuItem' parameter of "Checked=true" read it's values from an INI file or registry key, rather than the default of having all monitors found selected? This would allow the tool to launch with only the desired monitor(s) inverted each my computer reboots. I understand that this version of the tool really isn't being maintained with all the latest features of the main version, but it has everything I'm looking for. I'm thinking others would like this feature as well.

Thanks, https://0.x2a.yt/other/private/NegativeScreen-custom-multi-monitor.exe (mirror 1, mirror 2) is crashing on my Windows 7 SP1 x64 Ultimate (Aero disabled) when it starts. Any idea what could be the reason? The normal NegativeScreen.exe works fine.

Edit: EveryOtherUsernameWasAlreadyTaken found the issue: that's because I had OneNote running. OneNote registers the Win+Alt+N hotkey (try pressing it, a OneNote quick note will open) which makes the multi monitor tool crash. Closing the OneNote tool fixes the issue.
The multi monitor version also crashes on my Windows 10.0.18362.836 x64.

Exception type is the same as @Franck-Dernoncourt
The original NegativeScreen cannot register the hotkey as well, but it does not crash and shows a message instead.
In my case, the hotkey was already in use by OneNote for quick notes. Closing the OneNote panel made it working.
Sorry about that.
@Franck-Dernoncourt no idea about your crash. There is not enough information in the log. It might be the same crash as @EveryOtherUsernameWasAlreadyTaken ... If that's the case, removing or changing the hot key binding Alt+Win+N might fix it.
I need to find the time and motivation to rewrite the whole application... 😶
@mlaily thanks, no worries, @EveryOtherUsernameWasAlreadyTaken found the issue. Thanks for sharing https://0.x2a.yt/other/private/NegativeScreen-custom-multi-monitor.exe, it's very useful!
Is the source code for this multi-monitor ver. available anywhere? I'd like to modify it to only activate when a particular Window is in-focus/visible/maximized.

Yup, the branch is there: https://github.com/mlaily/NegativeScreen/tree/custom_multi_monitor_support

Perfect, thank you. Just in case anyone wants an example of such a modification, check out my fork here: https://github.com/HeatPhoenix/NegativeScreen-Vivado-Edition-
This is a very good program to keep handy. Showing negative/inverted image is a favorite way of many LCD monitors to fail. I have a LCD monitor that has developed a fault and shows negative colors.
I am using a dual monitor setup and this program is able correct the color problem but I am facing another issue. When NegativeScreen-custom-multi-monitor.exe is used, it somehow zooms the display approximately 150% on the faulty monitor. Other monitor is not zoomed. Kindly inform if there is some configuration setting or file entry that might be causing this.
The latest version of NegativeScreen.exe doesn't zoom the display but it inverts both displays.
Thanks.
@vks2005 NegativeScreen is not supposed to affect scaling at all, there are no option to do that. Maybe your problem is dpi related: does your screen uses a 150% scaling factor by any chance? I'm not sure it works properly with this version of NegativeScreen...

Thank you for the insight. Looking into Windows10 > Settings > Display and selecting the affected monitor I found that "Change the size of text, apps and other items" settings was set to 125%.
I had done this long time back as this second screen is placed a bit further away from me. Normally this setting increases only the text size but while using NegativeScreen-Multi-Monitor it started to increase size of everything. (Window size, dialog box size etc).
After resetting it back to 100%, everything is perfect. After a slight HUE adjustment in the display driver the monitor is working like a new one. LCD monitors have a circuit part that fails quite often and monitor starts showing negative images. It is a very common problem.
Thank you for making this useful software and also for the insight.
Hey @mlaily. Sorry for refreshing old thread, however is it possible to add multi monitor support to main branch? Your old second branch-release works on my W10 but is very limited without many without many features from main release. Thank you for for all your work.
@Atexor unfortunately, multi-monitor support only works with the old (slower, more buggy, and harder to use) Windows Magnifier API (the one used in older versions of NegativeScreen before the full screen API existed).
I've been wanting to do a new version supporting both methods, since they both have their pros and cons, but I never found the time to really work on it (sorry).
One day... :)
It's based on the old v1, and handles multiple monitors with the ability to choose to enable monitors separately.
It's a bit crude, but probably still usable: https://0.x2a.yt/other/private/NegativeScreen-custom-multi-monitor.exe
It appears the link no longer works. I would very much be interested in trying this.

Here you have it: https://zippysha.re/E6c37dw8zc/negative_screen_left_win_alt_f4_exe
I changed a bit name to remember the shortcut to change colors since I don't use it every day. Still works on latest Win10 build. You can disable effect on icon on taskbar, but disabling completely is possible only via task manager.

Thank you so much. This may be my last, best hope, to make an eyesore log display black instead of white. I will have to update some image backups before attempting this, as I have a "well broken in" Windows 10 which will require a .net update to run it. ;)

Hello! The link does still work, but it's hosted on a server living on my home internet provider, and it was unfortunately down the whole day today...^^"

That's awesome. It's good to see people are still doing that. I used to host a website myself from a junk computer on my cable connection 20 years ago, and I plan on doing so again in the future.
Being independent is nice, but still in a datacenter is better.
Because at home, not only your downtime is higher due to domestic service levels, but you're also more exposed to electrical, fire, heating and DDOS issues, and you're also wearing out faster if using non-server equipment.
If may I interrupt, @mlaily does your plans to regarding multi-gpu support on newer version of NegativeScreen changed? Do you have a bit more time :)?
