Oh I see, so you expect people to do it before they arrive/connect (or those links are allowed through your Sophos box at all times)? Or is there an open network for grabbing that stuff? Hopefully I'm making sense. Thanks, Mat

Hi kieran1990, I guess you host a captive portal page or something on another server (where you list instructions/distribute the CA cert)? Kind regards, Mat

Hi DJ_Teach, Based on your post I got in touch with Justin Comroe the chap that built the software (via the contact details on the website listed above) who was enthusiastic to help and very happy that the software was finding a use in Education. He has assured me that the software isn’t malicious in any way and is happy for anyone to submit the setup files and binaries to AV providers for analysis. Basically, his reply was that he's not hugely surprised that the software triggers some heuristic scans through some AV software packages and generates false positives. The original setup file was created with InstallShield (produced by SetupFactory 8) and hasn't been touched since it was pushed out for Shareware review (where it was peer checked and found to be clean) in 2015. He said: “I do see that there's quite a few detections on VirusTotal right now, so you're absolutely right on that part. DisplayClone itself {and all other executables within} are packaged with "Obsidium" [for code-protection / activation], and do contain code-virtualization. Given there's code-signing cert on any of the binaries, I'd suspect that modern heuristics and to blame here coupled with the packing -- {e.g, that the software performs hook injection, uses low level hooks, web-access, window manipulation, shared memory,etc}. For the sake of experimentation, I re-ran the unpacked (unprotected) binaries through VirusTotal. Seems that there's still some false positives on the loader processes, yet everything else in the clear with the exception of "SecureAge" on the TTS module (SpeechCore) and DisplayClone itself. Will look into this a bit more, could probably drop the software protection in future builds as we're no longer charging for the product.” Justin also provided the attached zip-archive with the obfuscation-free test binaries that can be run/analysed individually. “The more well known that the software is, the less false-positives that should exist as each company does their malware analysis.” Justin is aware of this thread, so he might register and get involved himself. He’s said if there is enough interest he may rewrite/update the software too. Zip/Hashes included below.

Thanks, yes I checked out this solution too, the DisplayClone software has a few extra features that are worth exploring though. Keeping a history of frozen screens as mentioned above for example and there are a bunch of settings that can be customised, like audio notifications that tell you when you have enabled/disabled cloning etc.â€

Hi folks, just posted a potential fix. /forums/how-do-you-do/235214-projector-replacement-tvs-teachers-missing-freeze-screen-pause-function-fix.html#post2013444 Mat

Good afternoon all, We've been keen to replace projectors with TVs as they're easier/cheaper and better in many ways. However - some teachers really miss the freeze screen/pause option that projectors have and we've spent a while trying to find a solution for this. In the end the following seems to be the best/most functional solution that we've found so far (for Windows 11 devices) so I thought I'd better share the info as it might be of use to others. Freeware produced by CamroeStudios called DisplayClone seems to have solved things for us. https://www.comroestudios.com/DisplayClone/Doc/DisplayClone.html With a second screen configured in extend mode users can open this software and clone their active screen to the extended display by pressing ctrl+m. Once cloned cltr+p can be pressed to pause the display on the second screen (allowing teachers to change to work on the next thing they want to display/something else, the software is also configured to keep a history of paused screens that can be scrolled through with ctrl+shift+left/right arrow keys (there are a number of customisable options in the software which are useful too). However - in order to make the software work for non-admin users we had to come up with a solution which allowed it bypass the UAC prompt. This was resolved by creating a custom sdb file in the Windows 11 ADK. https://techcommunity.microsoft.com/t5/ask-the-performance-team/act-suppressing-elevation-prompts-for-legacy-applications/ba-p/374734 Step 1: Install DisplayClone Software. Step 2: Install sdb file (e.g run the following command from an elevated prompt "sdbinst c:\DisplayCloneInvoker.sdb"). Step 3: Test/Trial. We noticed that differences in some resolutions/screen sizes can cause some artefacts (this seemed to be fixed be making sure scaling was set to the same percentage on both the primary and second screens). Hopefully this helps you out. Mat DisplayClone.zip DisplayClone.txt
