Gerald Evans posted a comment on discussion Improvements
From what I remember, this would require DMT to install a DLL to handle this and I wanted to keep the install process simple, so decided against implementing this or at least until I fond a simpler way to implement it. A quick search found another open source program 'SpecialK' (https://github.com/SpecialKO/SpecialK) which does seem offer this functionality along with lots of other features for gamers. I have not tried this program myself, but it may offer what you want.
-
Your idea would work if all of your monitors have different target names, but if you have 2 or more monitors of the same type, then it will not be possible to uniquely identify them.
-
Sorry, but the only thing that I can think of is that you have something else running that keeps changing the windows settings.

Release 2.12

V2.12 - Update to indicate latest version
-
2.12

No. Currently only one key out of left-control, right-control, left-shift and right-shift can be specified, although you can also use a mouse button. Is there any particular reason why you would want to be able to use either control key?

clean up ready for 2.12

Installer updated for release 2.12

Updated documentation ready for release 2.12

It looks like you may have installed something else that starts before DMT that is using "Ctrl+Shift+L" as a hotkey therby preventing DMT from registering it. I've tried using "Ctrl+Shift+L" as you have with DMT and I found it works with both Windows 10 and 11 including after a reboot, so it doesn't seem to be Windows that is grabbing this hotley.
-
I'm thinking about doing a new release in August.
-
DMT now displays monitor name (if room) in option panels showing monitor layout
-
Tidying up the orientation code
-
DMT can now change monitor orientation
-
I don't know why DMT won't start with privileges when using the registry 'Run' method - which is what it currently uses. It does however work if the Startup folder is used instead to autostart it. This needs further investigation.
-
I'm guessing that if you try to start it up without admin privileges it will work? I'm also guessing that you are setting admin privileges with DMT.exe->Properties->Compatibility->"Run this program as an administrator"? If this is the case, then I can confirm that this doesn't work for me either. Instead, you will have to manually configure DMT.exe to startup with admin privileges. In this case you will want to make sure that DMT's 'Start when Windows starts' is NOT checked. This can be done using...
-
Hi, just wondering if this is a bug or not? DMT does not launch itself on a restart even though it is set to "Start when Windows starts." I have granted it admin privileges as well, it's the only program I have that behaves this way. Thanks
-
'Move to next screen' logic updated to better handle different display resolutions
-
Added desktop context menu
-
A work around for this would be to use a "user Defined Area": Manually position the browser window as you want it, then DMT->Options->'Swap Screen'->'User Defined Areas' Select one of the hotkeys and press 'Change...' Drag the cross-hair onto the window you have sized and setup the hotkey as required. Note that this is not needed on Windows 10 as it natively supports moving the taskbar and correctly sets the working area of the monitor so that DMT knows where the taskbar is.
-
Added hotkey etc. to move all windows to a single screen
-
If Options->'Wallpaper Changer'->General->'Change when monitors / resolution change' is ticked then DMT will generate a new wallpaper image that will fit correctly on your enabled monitors when it detects that some have been enabled/disabled. But you are asking if the original images can be re-used to generate sensible output when this box isn't checked and monitors are enabled/disabled. I'll take a look, and will implement if it is fairly easy, but I suspect it may not be as simple to implement...
-
The ShowDesktop command can now take 'X' as a parameter for screen with the cursor on it.
-
The Brightness/Contrast commands can now show the GUI and use 'X' for current monitor
-
The ChangePrimary console command can now take 'X' as an argument to make the screen that the cursor is on, the primary monitor
-
Thanks for spotting this. The code has been updated ready for the next release so that it now ignores windows that do not belong to the current virtual desktop.
-
SwapScreen operations now ignore windows that are not on the current virtual desktop.
-
Added supported image file formats for wallpaper generation to docs
-
Release 2.11
-
I know the terms that I used for cursor movement could be improved, but I still think it needs at least two options rather a single one. The cursor movement has 3 different states: 1. The cursor is free to move between screens unhindered. 2. The cursor is free to move between screens but encounters stickiness at the edge of screens. 3. The cursor is locked to a single screen (or primary working area). The only way a single hotkey would work with this is if it cycled between all 3 options, but then...

-
Thanks for the kind words and all of the suggestions. It will take me a little while to go through all of your suggestions and see which ones can be implemeted. I will report back when I have a better idea of what is involved. There are 2 suggestions that I will comment on now: There is a hotkey that can be used to toggle the sticky cursor: InOptions-> Cursor->Sticky, if you set a hotkey for "Cursor movement between screens is sticky" but DON'T set a hotkey for "Cursor free to move between screens",...
-
Most modern full screen games seem to take full control of the cursor bypassing the hooks available in Windows that I use to control the stickiness of the cursor, so this is to be expected and I am not aware of anything that I can do to rectify it when such games are played. It does however work with some (mainly older) games, but I've never investigated why it should work with some but not others.
-
Thanks for the idea. I'll have a think about this for the next release.
-
If you go into the options and Launcher->HotKeys, you can see and change the laucher hot key in the "Activate Magic Word input" line. Note that Windows 10 has pinched win+q for itself, so you will need to use another combination. To get it to regenerate the magic words: 1) In options go to "Dual Monitor Tools"->General. In the "File Locations" section make a note of the location of the "Magic Words" file (you can Ctrl+C this if it is easier for you). 2) Shut down DMT. 3) Delete the magic word file...
-
It should handle any that are natively supported by .NET. This would be: BMP, GIF, JPEG, PNG and TIFF. Thanks for pointing out that this is missing from the docs. I'll add it ready for the next release.
-
Unless I am misunderstanding what you are asking for, you should be able to do this using "User Defined Areas".
-
I think that if you tick "Allow cursor to return freely to (and within) the primary working area" on the Curosr->Sticky options page, you will have the functionality that you are after. If not, please let me know.
-
DMT v2.11 has just been released with the above mentioned support.
-
DMT v2.11 has now been released which has a new option "Change Wallpaper periodically" -> "But not if running full screen game or presentation" which if checked will stop the wallpaper changing while running full screen games.

DMT v2.11 has now been released which I hope fixes these issues

Fix for start up of hooks thread
-
I suspect this may be due to the same problem as reported by Bort for which I have a fix. I had been delaying the release in case any other issues turned up, but 2.11 should be out within the next two weeks which I hope will fix all of these issues with stickiness stopping working.
-
I can't see why it shouldn't run on your miniPC. If the DMT icon is in the notification area and you can right click on it and see the context menu ('Options', 'Enter Magic Word ...' ... 'Exit')., then DMT is running so it should not be an issue with the .NET framework. The only thing I can think of suggesting is to uninstall it and install an earlier version of DMT I would suggest trying version 2.3 which was before DMT interogated the monitor connections, just in case there is something unexpected...
-
I have looked at this, but there are some technical issues that need to be resolved and I haven't decided on the best solution for these yet. As an alternative solution to this, there is a 'List' provider that you can use as an alternative to 'Local Disk'. With this you can create a file containing the full paths to all of your images. (On the List provider options dialog, there is a 'Auto Generate...' button that can automatically generate this list from all of the files in a directory.) The 'List'...
-
Cleaned up the cursor hook code
-
Thank you for the updated steps to reproduce the problem. I can confirm that I can reproduce the same problem with the existing version of DMT. The reason why I have never seen this is because I open the options using the Launcher. If you want to do this, then you will need to go to Options->Laucher->HotKeys->"Active Magic Word Input"->Change and define a hotkey. You can then just press this hotkey and start typing "Options" (you should only need to enter the first letter unless you have other magic...
-
Cursor hooks now run in their own thread
-
Refactor of CursorModule to split out the hooks code
-
Point taken about defining the extra hotkey. I am surprised that just changing the settings is causing this problem for you. Are you saving the settings on a slow or busy disk drive? I'm fairly certain that I know what the problem is now, and am looking for a solution.
-
In the directory containing DMT.exe, there should be a file called DmtFileLocations.xml. (If you have done a manual/portable install, there will be a DmtFileLocations-sample.xml that can be renamed to DmtFileLocations.xml) Using a text editor on this file, you can change the value for the "datadirectory" entry to point to the required directory. You will need to restart DMT after editing thie file.
-
Sorry about the delay in replying, but initially I had difficulty in reproducing this problem. I have now found a way to reproduce this, but have yet to find exactly what is causing the problem. However, instead of restarting DMT when this happens, there is another option: You can use the hotkeys (specified on the same page) to set free cursor movement (you will also need to uncheck any checkboxes on the 'Dead Space' options at the same time if you are using them). Then use the hotkey to set cursor...
-
Any chance of posting images of Cursor->'Primary Working Area' both before and after this happens? If your monitors + TV are all the same size, then the info on 'Dual Monitor Tools'->Monitors may also be needed to identify which monitor is which. The 'Primary Working Area' remembers the screen numbers of the monitors in the primary working area. If the screen numbers change, then this will cause the problem that you are seeing. It may be worth trying both options in 'Dual Monitor Tools'->'Monitor...
-
I have not tested this with Opera, but I have found a solution for Chrome and as I believe Opera supports most of the command line options that Chrome uses, I hope this will also work for Opera: In Chrome the initial starting position and size can be specified by the command line parameters --window-position and --window-size. So, when setting the magic word, in the parameters text box, you can specify the starting position and size with something like: --window-position=953,0 --window-size=974,1047...
-
The next version of DMT will have a new option where you can disable wallpaper changing if DMT detects that a full screen game or presentation is running.
-
Added option to not change wallpaper if gaming/presenting
-
Yes, my guess would be that it is due to an unsupported image type/subtype as well. If you are using DMT 2.10 and enable logging, then any such images will be logged. In short, to turn on logging you will need to enable the "log" entry in DmtFileLocations.xml and restart DMT. The longer version, assuming you have not made any previous changes to DmtFileLocations.xml: 1) Copy DmtFileLocations-sample.xml from the directory where DMT.exe resides to a directory where you have write permission, eg. your...
-
I'm guessing that you have the "Use smooth fade when changing wallpaper" option set. This uses the Windows Active Desktop to perform the smooth fade which uses the GPU to accomplish this. There isn't much I can do about this without implementing my own smooth fade, which probbaly wouldn't be very smooth unless the GPU was used. As a short term solution, I would recommend turning off this option when gaming. If I can find a way to detect when a game is running or when there is high GPU usage, I will...
-
DMT can't do this, and I am not aware of any other tools that will do this, but hopefully someone else does?
-
The fix will be in the next release which will be 2.11.
-
Thanks for the detailed description as that helped to pinpoint the problem. It happens when the screen resolution changes but before Windows has informed DMT that the screen resolution has changed, as the sticky cursor code was using a combination of screen resolutions both before the resolution was changed and after the resolution was changed. The code has now been fixed ready for the next release.
-
Re-worked position to monitor code to prevent problems when monitor resolution changed
-
Sorry, can you explain what you mean by "tab out of black bars"? I don't follow what you are doing when the problem occurs. Also, if you can explain which features you are using, like sticky cursosr or the wallpaper changer and if the DMT GUI is open at the time. Thanks, Gerald
-
Thanks for the suggestion, but I'm not sure if I can detect if a window is being dragged from within the sticky cursor code, but I will take a look at it at some point and if easy to implement, will add it in to the next release.
-
It is the 'Cursor movement between screens is sticky' hotkey that you would need to set if you want sticky cursor activated rather than 'Cursor free to move between screens'. Also, worth checking that the 'Resistance to movement between screens' slider is not set at the minimum. If this doesn't help, then does it work if you set 'Default cursor mode on startup' to something other than 'Cursor free to move between screens' and then restart DMT or your computer? If so, then it may just be the hotkey...
-
If you have multiple users on your computer, then each user should have their own settings. But I guess that you are talking about a single user having multiple settings that you can switch between? There is no built in way to support this, but it should be possible to achieve this with batch files. If you look at DMT->Options->'Dual Monitor Tools'->General, you will see where the setting files are held. So when you know which settings you want to switch between, you would create 2 variants of that...
-
Just added support for F13 through F24 ready for the next release.
-
F13 to F24 can now be used as hotkeys

Thanks for spotting this. The monitor number to put the snaps on was being reset every time the options dialog gets displayed. A fix has gone in ready for the next release to correct this.

It's not the multiple aspect ratios that is causing the problem, but the size of the resultant rectangle that covers both the width and the height of your entire monitor layout. It also depends on how well PNG can compress the images that make up the wallpaper which is why some generated wallpapers can be displayed and others can't. With people using larger monitors, this area is getting larger and becoming more of a problem as the resultant PNG image can now easily exceed the limit that Windows...

WallpaperChanger: Added option to set wallpaper image type/quality
-
It's not the size of your input images that matters but the size of the generated PNG image that covers all of your monitors. It may be that Windows has reduced the maximum size of PNG file that is supported for Windows Wallpaper between 10 and 11, but I have not done any experimentation with this.
-
I think the problems with the black background is due to a limit within Windows of the maximum size of a PNG file that can be used for the background wallpaper. I have managed to replicate this on both Windows 10 and 11 using Explorer and "Set as desktop background". So it might work for a while, but if a composited image file ends up being larger that this limit, then you will suddenly get the black display. I've not worked out what the PNG file size limit is, but it looks like it is somewhere between...
-
It looks like Windows has a file size limit when displaying PNGs as background wallpaper so when DMT produces a wallpaper larger than this limit, it results in the black background. DMT switched from BMP to PNG as Windows seems to internally convert BMP to JPG before using it as wallpaper which was reducing the display quality. However, there does seem to be a registry setting that can be used can control the JPG compression/quality level when it does this, so that should help. A new option will...
-
First, can I check if you are using the 'Wallpaper Changer' in DMT or are you generating the wallpaper manually with DualWallpaper.exe? I've had DMT running with these 3 files for quite a few hours and have not noticed any problems. This was on Win 10 Home, 22H2, 19045.3208 When I try to set your 'DmtWallpaper - error 1.png' as desktop background, I do get all black, but I think that is because Windows does not support this format. Ideally a .bmp file needs to be used to ensure it can be displayed...
-
If you are trying to lock the cursor out of a single monitor and that monitor is at the exteme end of your set of monitors, then this can be achieved using Options->Cursor->'Primary Working Area'. Select all of the monitors apart from the monitor that you want to exclude and then set the required sticky/locked options on Options->Cursor->Sticky. You will then be able to move your cursor freely between all of your monitors apart from any that were excluded from the Primary Working Area.
-
I've not tried DMT on Windows 11, so there could well be a compatibility issue here. I already know that there are issues with the DMT's wallpaper changer and Windows 11 and hopefully I will soon be in a position to sort out DMT support for Windows 11. I don't know why supersize for you is producing such a small window. Does the same thing happen with other windows, eg. Notepad etc? Did you see this issue on Windows 10, or is it only with Windows 11? Supersize doesn't make a lot of sense if your...
-
This is Windows stopping you from creating a window that is larger than your total screen area. I've never tried to see if this limit is just in the Windows UI or if it is something built into the low level Windows code, which would mean there would be no easy way of overriding this.
-
On Options->"Wallpaper Changer"->General: disabling "Use smooth fade when changing wallpaper" should result in faster wallpaper changing.
-
Assuming that none of your images are corrupt, then I think the most likely issue is that some of your images are using attributes that are not supported by the JPEG implementation within .NET/GDI+. https://stackoverflow.com/questions/25723855/outofmemoryexception-out-of-memory-system-drawing-graphics-fromimage details this problem. If you can identify the images that are not displaying, then one solution seems to be to load them into say Windows Paint, and then re-save them, as mentioned in the...
-
In that case, my guess is that some of your images may be in a format that is not recognised or fully supported by the .NET code used to load the image ( https://learn.microsoft.com/en-us/dotnet/api/system.drawing.image.fromfile?view=windowsdesktop-7.0 ). Unfortunately, I silently ignore any images that can't be loaded. I may change this in the next release to log the image filenames that can't be loaded. Are you using the "Different image on each monitor (all changed together)" option? This can...
-
Which provider are you using for the images? It looks like it is failing to load one of the images, so I guess these are being downloaded over the internet?
-
DMT can only move the active window to a UDA or a SDA, so probably not the best solution for you unless you want to select each window in turn and press the corresponding hotkey for where you want that window to be. There is no ability to move multiple apps with a single hotkey. However, there is the ability to start multiple apps with a single operation and have them move to a designated area (this may not work with all apps as some want to control their own startup position). To use this, Options->Launcher->'Magic...
-
Have you tried checking/unchecking "Use smooth fade when changing wallpaper"? Depending on this setting, different Windows API calls are used, so there is a chance that the other option would work in Windows 11.
-
Sorry, DMT does not currently support this feature. It may be something that I will add in the future. If you go back to version 1.10 there was a tool called DisMon which offered similar (but different) functionality to Win+P but it didn't support hotkeys and only supported 2 monitors and I don't know if it will run on anything later than Windows 7.
-
Thanks for reporting this. A fix has gone in ready for the next release. There are 2 possible workarounds to save restaring DMT while waiting for the next release: 1) View the DMT options page (you don't need to go into any of the individual options) before plugging or unpugging a monitor. 2) If you have already plugged in a monitor when this happens, go into options->'Dual Monitor Tools'->'Monitor Order' and change the 'Order by' option and then back again. It should now spot the monitor you just...

I've not tried Windows 11, so there may well be an incompatibility issue. I hope to get Windows 11 shortly, so will check it out then. In the meantime, if anyone else viewing this thread is using the Wallpaper Changer and Windows 11, I would appeaciate it if you can say whether it works for you or not. Thanks.
