When I try and open the TheocBase program and I have dual screens, the program will not open.  It starts, hangs and closes without opening a UI.  If I change to have only one screen active, it works fine.  Since I use dual screens as default, specificly with the computer I use to schedule with, this is not productive for me.

I have another piece of the puzzel.  With my dual screens, my main screen is my external monitor, on the right.  I set that as the main screen.  However, if my laptop screen is set to be the main screen, it opens just fine.  Hence, when initilizising the display, if it sees the value for the main screen is not what it expects, then it crashes.  However, swapping the screens works.

Just wanted to post an update for this.  After the last update, it still has the same issue.  However, with the last Ms update to windows 10, when I have my second screen plugged in, it automatically reconfigures my system to dual screen support.  If I get theocbase opened soon enough so that the splash screen opens when it is in single screen mode, when it goes back to dual screen it will work fine.  So it seems that there is something in the splash screen or startup that crashes.  When I try to open this, it never shows the splash screen at all.

 

Hope this gets you some info to look at .

I found and used another USB adapter (USB-c) and it actually worked on that one (didn't previously).  I just updated the drivers for the video card, and it still doesn't work.  However, if I duplicate the system, it works.  There just seems to be something funny that happens when the display is extended.  It will work if I show only the external monitor, or if I duplicate it.  But, for just this one program and this external display adapter, it doesn't like to open with the extended display.  This is a Targus Dislay Link port replicataor.  It has two HDMI ports and a Display port. I changed what HDMI port it was plugged into, but that didn't change anything.

Hi John, thanks for your answer.

 

Can you tell us which version of Theocbase you are using?

Does the problem only occur if you EXTEND your display to the second monitor?

Or does it also occur if you MIRROR the display of your laptop on the second monitor?

Does it also occur if you switch the display firmly to the second monitor?

Because another port replicator in your setup causes the same problem, I would go on to find the cause on your laptop.

First I would set the resolution of the laptop to 1920 * 1080 and use the native resolution (without zoom).

Can Theocbase still be opened without connecting the port replicator?

I'm assuming that works...

Then I would connect the port replicator with the 27 "monitor and check if the settings in Windows still fit (also resolution 1920 * 1080 without zoom).

Can Theocbase be opened by connecting the port replicator?

If so, I'd recommend running the setup like this in future (in my opinion, such a high resolution on a 12 "display does not make much sense anyway, especially as you set the scaler to 150%; better a lower but native resolution).

If not, I would follow the replicator's guide:

"To ensure the best Windows performance, please be sure to update your host."

You could check if your chipset, Serial IO, VGA Driver and possibly the "Other Drivers" are on the last Acer stand.

The drivers can be found here:

https://www.acer.com/ac/en/GB/content/support-product/6806?b=1

You can check the drivers of your system via the Device Manager (Windows Key + X => Device Manager).

In the Device Manager (on the appropriate device) with right-click you can klick => Properties (Driver tab) and check which driver is currently being used.

You can do an update of the drivers - but do it at your own risk ;-)

Perhaps Theocbase also offers a debug mode to evaluate the crashes of the program.

I could not give you a syntax or the path for such logfiles for that. Maybe one of the moderators or developers knows more.

Hi John, interesting problem.

Maybe you are able to give some more information about your setup?

Which operating system in which version (for example Windows 10 64bit) do you use?

Which version of TheocBase do you use?

What resolution do you use on your monitors?

Are both monitors resolving at the same resolution?

Do you use a laptop with a dedicated graphics card (f.ex. first screen is embedded laptop screen and second external monitor)?

If so, which manufacturer is that and which driver version do you use?

Do you use the second screen as an extension or as an mirror screen?

Or do you use a desktop PC / Mac? Again, the graphics card manufacturer and the driver version would be interesting.

Did you already use Theocbase with this setup, or has it never been with two monitors?

If it has already run, can you say what changes have been made since then (updates, or similar)?

I can use your information to try to simulate the problem.
(I'm using Windows 10 (64bit) OS, TheocBase Version 2018.6.0, 14" laptop (embedded screen with resolution 1366x768) with dedicated Nvidia graphics card (driver 381.65), connected 24" monitor with fullHD resolution (1920x1200), monitor expansion mode - no issues so far to open and use the programm, no matter on which monitor (resolution)). 

Best regards
Fabian
