Hello All,
I just started using ProScan for the first time and am using 15.3. I'm still on the 30 day trial, but intend to purchase within the trial period.

Here's what I'm seeing: I have a Windows 7 x64 machine that is headless (no direct attached monitor or mouse) and use Windows Remote Desktop to manage the machine like a home server from any remote location. I run ProScan on a secondary active login that has full administrative rights. When I use Chrome, Firefox, or Safari web browsers either on the local LAN or remotely outside of my local LAN (using any web browser from the internet) through my port-forwarded firewall, I can only see the SDS200 active display if I have a separate Windows Remote Desktop session active. Once I close the Windows Remote Desktop Session, but leave the user login and ProScan application active, the scanner display section of any web browser goes to blank black. The lower Stream Description Panel metadata still works, but I wonder why closing a separate Remote Desktop Session makes the upper Scanner Display section go black.

Love ProScan.

Does the display shown in the Web Browser is regular size or smaller like a placeholder image? If smaller then is ProScan minimized?
There is a Windows limitation if ProScan is minimized then Windows will not "paint" the display and that will happen.
I have on my list to try to come up with a work around but it will be a while before I get to it.

If the display is regular size then I don't know what could cause that. Perhaps a screen shot so I could try to see what is happening.

I'm not familiar with Remote Desktop Session so I don't have any ideals on that.

Hello Bob,
No the web browser can be full screen, either Chrome, Firefox, or Safari, and the scanner portion of the window is black. If I open a completely separate Windows Remote Desktop Session and login to the user login that has the ProScan running, then the web browser scanner window will begin working. When I lock (not log out, of course, which would close the ProScan application), the user login and close the remote desktop session, then at the metadata/audio delay time, the Scanner window on the browser goes black. Neither full screen or minimized on either the ProScan application, or the local web browser, seems to have any effect.

Question: Is it designed that ProScan would run on a windows machine with the local windows user login account ProScan is running in to be unlocked and showing on an attached monitor at all times?

PS. I use NVIDIA video card and drivers.

Don't really under stand the question but ProScan and the ProScan Web Server doesn't take in to account "local windows user login account".
The display should show on an attached monitor at all times so it can be "painted" by the OS

I see the screen shots appear okay. The one with no display looks like a different problem then what I was thinking with the OS "painting"
I don't know what it could be. Perhaps someone experienced in Remote Desktop could chime in.

I'm not sure what can be done to the Web Server to resolve this. I haven't seen this before. Is there anything on your side that can be setup differently or a Remote Desktop option?

On thing you could try is go into the Options - > Scanner Specific and choose Use ProScan Colors versus Sentinel Colors.

Another thing to try is go to the Test & Extra tab and set the Virtual Display Test.

Hello Bob,
I tried changing back to Sentinel Colors to the default ProScan Colors and then back again. I also tried the Test & Extra tab and set the Virtual Display Test checkbox. In each, the local Windows Remote Desktop Client had to have the remote machine Windows user login be open and displaying the ProScan running application for the separate local web browser to show the active SDS200 scanner display. When the local Windows Remote Desktop Client session was disconnected from the remote machine, but leaving the ProScan application running in the locked Windows user login account, the separate local web browser session scanner display went black. But all the other local web browser session information from the remote ProScan running machine, (metadata, etc.) is never affected. I can live with this, as the RSOIP client doesn't exhibit the same behavior, and in all situations I still always get metadata in the web browser.

Thanks for trying. Maybe the answer will come up at some later date.

Update: I moved ProScan to a different computer. ProScan now “paints” the SDS200 Web Server scanner screen display with Sentinel colors screen on a remote java-enabled browser properly, regardless of my headless (no monitor or mouse) remote use of this second computer with Windows Remote Desktop. So it seems the first computer with it’s two physical displays served from it’s single video card: An Nvidia display card serving an primary LCD local monitor, and also serving a secondary HDMI Home Theater Sony TV, caused ProScan Web Server SDS200 Scanner screen display output redirection issues. So all is great now. And I can still use Windows Remote Desktop to manage this second computer ProScan Server.
