Default Dell Display Manager

Anyone here with a Dell Monitor and using its additional software 'Dell
Display Manager' (DDM)?

I recently bought the 24" Dell U2514 monitor and am happy with it apart
from the DDM. I prefer to manage the size and position of open windows
myself (and have various macros to assist). I couldn't find any way to
stop DDM rearranging my windows every time I enabled the monitor, even
by closing it from its tray icon. So I uninstalled it (thoroughly, using
Revo Uninstaller).

But windows of various apps are *still* appearing at some previous size
and position that I must have set during my early experimenting a few
days ago. Can't see how that can occur.

Bottom line: I want my windows to remain at whatever settings they were
in when last used, but I'm stumped how to return to that normal state.

We've had issues with Fujitsu's Display Manager; I basically recommend
not to use those. As for your problem, if you've uninstalled it then it
should no longer be moving windows around; just re-position the windows
and close/restart the programs. Unless these programs have some sort of
registry keys for constantly positioning their windows (unlikely,) and
providing you've re-enabled "open at last position" settings in said
programs, you shouldn't have issues (tho I'd be surprised if DDM messed
with program settings at all.)

It seems that on re-powering the display, even when DDM had been closed,

was in place. Rather than reverting to the OS settings.

I uninstalled again and on closing down and re-powering the display this
was my screen:

It looks like a resized version of the 'acceptable' layout I'd set as my
fallback. Instead of the originals.

Maybe I'll now try uninstalling the monitor driver.

Dell Display Manager is an "OEM" software written by EntechTaiwan.com.
Makers of Powerstrip and Moninfo.

Apparently, there is a support address for the Dell OEM product.
An email address at the entechtaiwan.com domain, and it is listed here.

https://www.dell.com/community/Monit...t/td-p/4516638

Maybe you can ask them whether there is any way to return
the machine to the state before DDM got installed. They are
known for having good tech support (likely developer class
people). You won't get a "drone reading from a script"
to draft a reply to your query. I'm sure the DDM product
has driven their support issues through the roof :-)

Thanks Paul, an email was going to be my next step so you've saved me a
search.

Duly emailed.

I've now gone one step further and in Device Manager reverted to the
built-in Microsoft generic drive. I'd have given good odds that would
fix it - and lost my cash.

Apart from an SR I can't think of anything else to try, and I'm
reluctant to do that as it might affect other stuff.

Is there a "Restore to Defaults" (or similar wording) option in the
monitor's OSD? On my Asus monitor, under System Setup, there's an "All
Reset" option.
Maybe that would clear whatever memory setting the monitor may have.

Thanks, yes, I'm pretty sure there was and that I tried it without
success. But if I don't get an email reply from Dell soon I'll reinstall
both the driver and DDM and check that again.

I did some lengthy searches with Regedit last night. Either I didn't
choose the right string or the registry had nothing to offer. I'll try a
few more strings.

Just removed and replaced the power and the mini DPort ('mDP') cables
and also restored to 'Factory Default Settings' via the on-screen
display menu. Still getting that same memorised layout on every restart.

FWIW, the Agent window was at 0,0 size 1441 x 1172
On restart that becomes 2,2 size 1022 x 736
The folder window was at 1440,0 size 480 x 1172
On restart that becomes 1020,0 size 480 x 738

Have not yet reinstalled the DDM.

You know that the monitor knows absolutely nothing
about the pixels on the screen.

The monitor works at the "panel" level. The EDID
contains a list of supported resolutions.

1920x1200 @ 60Hz
1920x1080 @ 60Hz
1280x720 @ 60Hz
...

When the system starts, the video card can read the
EDID serial bus and transfer the 256 bytes of data
(of which perhaps the lower 128 bytes are useful).

Once that is done, the 1920x1080 window is a "blank slate".

The monitor does not get a say in where the Agent window goes.

DDM does not send a command to the monitor, to make
the Agent window appear at certain coordinates.

The video card does compositing, and arranges windows
in Z-buffer order, so the window with the highest priority
appears in front of the others. Via compositing, a viewport
with the shape of the screen (1920x1080) ensures that
windows which are partially offscreen, the offscreen bits
don't do anything. They're clipped off (of course).

It's Windows that decides where to put Agent. Based
on registry settings. If no registry settings are
available ("first run"), then the tiling logic decides
what coordinates are appropriate.

If DDM modifies an Agent registry entry, then the position
could change. Maybe there is a separate area of the registry,
an area not owned by Forte Agent, which is used to store
X,Y,W,H of the application. Knowing Microsoft, it's probably
the GUID of the application which is used to index a
registry table of some sort. You would need to use (clsid?)
the table in the registry, that gives a GUID for an application,
because the registry contains many many "two stage lookups"
for stuff. Microsoft doesn't want settings to be available
in one lookup, because users might succeed in fixing stuff.
ProgramName -- GUID -- table_with_thing_needing_changes

The EntechTaiwan people are wizards with the registry.
If there is a setting in the registry, they know about
it. For example, when Windows goes nuts and uses a
screen setting which the multisync monitor reports
is "Out Of Range", the EntechTaiwan people know where
those settings live. And depending on display class,
the settings are *not* all in the same registry section
either.

We've had issues with Fujitsu's Display Manager; I basically recommend
not to use those. As for your problem, if you've uninstalled it then it
should no longer be moving windows around; just re-position the windows
and close/restart the programs. Unless these programs have some sort of
registry keys for constantly positioning their windows (unlikely,) and
providing you've re-enabled "open at last position" settings in said
programs, you shouldn't have issues (tho I'd be surprised if DDM messed
with program settings at all.)

Regards,


I uninstalled again and on closing down and re-powering the display this
was my screen:
https://www.dropbox.com/s/mjrogtfumr...em-1.jpg?raw=1
It looks like a resized version of the 'acceptable' layout I'd set as my
fallback. Instead of the originals.


While it's possible it exists, I do not myself know of any way to ask
Windows itself to remember a program's position on the screen, unless
that changed with Win10. Programs have to do that themselves. What all
these Window Managers do, is move/resize windows as they are opened,
usually using the window-title to identify them. So if DDM is gone,
there should be no one messing around with the windows; they should
appear wherever the program themselves ask that they appear. However, I
do know of my own Intel Display Driver messing around a little when I
power-off a monitor with the computer turned on - The driver changes
the screen resolution back to whatever it is that the default Windows
Basic Display Driver supports, so all my windows move around the screen
(they all end-up squished top left.) Maybe your display driver is
messing around? Who knows, maybe it supports moving windows around the
screen as they open - are you using a special Dell Display Adapter Driver?

Maybe I'll now try uninstalling the monitor driver.

Try the Display Adapter Driver; get the one from the manufacturer, not
the Dell-Supplied one...

Thanks, appreciate your reply. And I do indeed wish I'd not installed
DDM ;-(

But it's baffling that after uninstalling it the issue remained. Here's
a more detailed explanation of the problem:
https://www.dropbox.com/s/jf5do72v0a...ut-1.jpg?raw=1

It seems that on re-powering the display, even when DDM had been closed,
or uninstalled, the monitor uses whatever the last saved preset layout
was in place. Rather than reverting to the OS settings.

Terry, East Grinstead, UK
Is there a "Restore to Defaults" (or similar wording) option in the
monitor's OSD? On my Asus monitor, under System Setup, there's an "All
Reset" option.
Maybe that would clear whatever memory setting the monitor may have.
(Clutching at straws, LOL!)
Thanks, yes, I'm pretty sure there was and that I tried it without
success. But if I don't get an email reply from Dell soon I'll reinstall
both the driver and DDM and check that again.


Just removed and replaced the power and the mini DPort ('mDP') cables
and also restored to 'Factory Default Settings' via the on-screen
display menu. Still getting that same memorised layout on every restart.

FWIW, the Agent window was at 0,0 size 1441 x 1172
On restart that becomes 2,2 size 1022 x 736
The folder window was at 1440,0 size 480 x 1172
On restart that becomes 1020,0 size 480 x 738

Have not yet reinstalled the DDM.

You know that the monitor knows absolutely nothing
about the pixels on the screen.

The monitor works at the "panel" level. The EDID
contains a list of supported resolutions.

1920x1200 @ 60Hz
1920x1080 @ 60Hz
1280x720 @ 60Hz
...

When the system starts, the video card can read the
EDID serial bus and transfer the 256 bytes of data
(of which perhaps the lower 128 bytes are useful).

Once that is done, the 1920x1080 window is a "blank slate".

The monitor does not get a say in where the Agent window goes.

DDM does not send a command to the monitor, to make
the Agent window appear at certain coordinates.

The video card does compositing, and arranges windows
in Z-buffer order, so the window with the highest priority
appears in front of the others. Via compositing, a viewport
with the shape of the screen (1920x1080) ensures that
windows which are partially offscreen, the offscreen bits
don't do anything. They're clipped off (of course).

It's Windows that decides where to put Agent. Based
on registry settings. If no registry settings are
available ("first run"), then the tiling logic decides
what coordinates are appropriate.

If DDM modifies an Agent registry entry, then the position
could change. Maybe there is a separate area of the registry,
an area not owned by Forte Agent, which is used to store
X,Y,W,H of the application.


With DDM currently installed yet again, If I look at the registry key
Computer\HKEY_CURRENT_USER\Software\EnTech\DDM
I see this:
https://www.dropbox.com/s/e28oaiinws...em-4.jpg?raw=1

And I'm guessing the details about windows layouts are as shown he
https://www.dropbox.com/s/m1sgyoxfx5...ry-2.jpg?raw=1
https://www.dropbox.com/s/kn5e6bvw2d...ry-3.jpg?raw=1

Knowing Microsoft, it's probably
the GUID of the application which is used to index a
registry table of some sort. You would need to use (clsid?)
the table in the registry, that gives a GUID for an application,
because the registry contains many many "two stage lookups"
for stuff. Microsoft doesn't want settings to be available
in one lookup, because users might succeed in fixing stuff.
ProgramName -- GUID -- table_with_thing_needing_changes

The EntechTaiwan people are wizards with the registry.
If there is a setting in the registry, they know about
it. For example, when Windows goes nuts and uses a
screen setting which the multisync monitor reports
is "Out Of Range", the EntechTaiwan people know where
those settings live. And depending on display class,
the settings are *not* all in the same registry section
either.


I had a reply from the forum monitor, suggesting the culprit one of my
other many scores of applications. I don't buy that and am hoping to get
something from the developers.

Later this morning (it's Thursday 13 September 2018, 10:30 here in UK)
I'll uninstall DDM yet again and repeat the registry check. Those
*should* all be gone, yes?

Agreed. (Of course, window size and position are easily manipulated. One
of the main reasons I want to be rid of DDM is that I use several macros
to do so with keystroke hotkeys. And no, that's not a candidate culprit;
no change with Macro Express Pro closed.)

However, I
do know of my own Intel Display Driver messing around a little when I
power-off a monitor with the computer turned on - The driver changes
the screen resolution back to whatever it is that the default Windows
Basic Display Driver supports, so all my windows move around the screen

That sounds a promising line of enquiry, as you see that my 'DDM
windows' were affected the same way, shifted towards the top left
corner. But the check below shows no *obvious* issues with my Intel HD
Graphics 530, which I recently updated:
https://www.dropbox.com/s/1poezrkcfh...ults.jpg?raw=1

One other place I looked was the Intel HD Graphics Control Panel, but
see nothing relevant there either, even though I have not experimented
beyond those default settings:

That was what updated only a few days ago, and the subject of that check
above. In fact that's what prompts me to suspect it, together with your
similar experience. Are you saying that was resolve by updating your
Display Adapter Driver?

As for the *monitor* driver, as mentioned up-thread I reverted to the
generic MS version (straw clutching) and that remains the status today:
https://www.dropbox.com/s/bpia198qv5...blem.jpg?raw=1

My thanks to you and Paul for patiently staying on the case.

Did you touch anything in the Easy Arrange page?


Eh? Of course I 'touched things'. I've been playing with it for several
days.
