Possible Windows 7 RTM Bug in MRC
by ryanw on Fri Sep 25, 2009 11:09 am
I'm using the final RTM build of Windows 7 x32 Enterprise. If the remote computer's display settings under "Control Panel\Appearance and Personalization\Display\Make Text and Other Items Larger or Smaller" are set to 125% or 150% you can only see a small portion of the screen over the remote control.
Has anyone else seen this issue?

I've tried the following things with no success to fix this.
1. Try turning on/off the "Use screen work-area for full-screen" setting under the Local Global options dialog.
2. Try enabling/disabling “Use smart sizing for full screen when necessary" under the Local Global options dialog.
3. Try turning on/off the "Resize window on Connect" option as well.

After runing some more tests on this it does not happen on all my Windows 7 systems. So far only ones with the Intel Series 4 chipset/ video driver.

Hi Ryan,
Honestly, I don't think this has anything to do with Font Sizes in the O/S, because MRC should not care about the Font Size on the remote machine. It sounds more like a possible video driver issue, specifically the Video Driver and/or O/S may be reporting the wrong resolution back to our software.
To test this out, connect via the MRC software, then select View / View Connection Information from the MRC main menu, and then look at the Resolution: field in the Connection Information dialog. We basically just ask the remote machine (via standard Microsoft Windows APIs) for it's resolution, and then we record the resolution that is reported back to us in the Connection Information dialog. This information is then used (in conjunction with your local machine's resolution) to determine the size of the MRC connection window.
If the remote machine is reporting an incorrect resolution, then here are a few possible work-arounds off the top of my head:
1. Look for an updated Video Driver.
2. Try a different resolution on the remote machine. It's possible that other resolutions may report properly.
3. Try making the resolution change within the software provided by the Video Card manufacturer, instead of via the O/S Display Properties. For Example, if you're running some type of NVIDIA card, then try changing the driver via the NVIDIA Control Panel (which should be installed when you install Forceware, etc...). It's possible the O/S is only making this resolution change locally instead of globally. Making the change via the NVIDIA Control Panel should make the change on a global level.
I hope this helps.

Thanks for the reply. The system is reporting the wrong resolution at 960x600 even though the display is set to 1440x900. It is like somehow that driver is adjusting the reported resolution when the "make text and other items larger or smaller" is set above 100%.
I'm going to try 125% and see if it reports another resolution. At this point I am waiting for a new video driver to come out.

Bryan,
Do you have any ideal how I can trick the dameware mirror driver into using the correct resolution? A registry hack or something as a temporary fix until I hopefully get a better driver.
Thanks,
Ryan

I have been working with Dameware support on this issue all day. I don't see how it is a video driver when another piece of remote desktop software displays just fine ex. NetOp. I also have a hard time believing this because if you logoff or lock the machine, disconnect from it, and then reconnect it will work fine. So for the time being I have been locking a users PC, disconnecting from it, and then reconnecting to make it work.
Also I have tested it with the onboard Intel Chipset and with an NVIDIA graphics card and neither one proved to be an issue or resolve the issue. I haven't had any problems with setting it to 125% but I can recreate it everytime when it is set to 150%.
I am also looking for a better resolution than what I am doing but will it ever come.

As a temporary work-around, instead of Locking the remote machine or logging off the user, and then disconnecting and reconnecting, try this instead. Simply press CAD via the MRC toolbar, and then leave the remote machine at the Lock / Switch User / Logoff.... screen. Now disconnect and reconnect. Once you have reconnected, press ESC to exit the Lock / Switch User / Logoff screen and the resolution should be correct.
I was finally able to somewhat duplicate this behavior, but only on one specific older machine running and older NVIDIA video card. All the other machines (ATI or NVIDIA) work perfectly fine. It also worked perfectly at 100 or 125%, even on this specific test machine. The issue only showed up on this one machine when you set it to 150%.
So from what I've found so far, the APIs return incorrect information on this specific machine, only when it's set to 150%, and only when a user is currently logged in at the time you connect. If the remote machine is at the Logon Desktop, Lock Screen, or Lock/Switch User screen, then the APIs return back the correct resolution.
We're still looking into a more permanent solution (work-around) for this issue, whatever that may be. Unfortunately, at the present time there is no definite ETA.

I have exactly the same problem, using Windows 7 at 1920 x 1080 on a 32 inch TV.
In order to still see the icons and text from a few feet I set the fontsize at 200%
The above mentioned workaround works fine, but I hope there'll be a solution soon!

We wanted to update those of you who have reported this issue to us. We were able to duplicate the issue, which occurs when the DPI is above 144, and have resolved it. It will be fixed in the next release of our software in the very near future.
Thanks everyone for the information you provided.

Will this fix be in Version 6 or 7?
Re: Possible Windows 7 RTM Bug in MRC

This should already be fixed in version 6.9.0.0, which was released earlier today.
