Hi David,
I'm currently running DRM 12.0.2.0 and operating with the following setup; W10 Pro laptop 3200x1800 with 200% dpi and an external display 3840x2160 with 150% dpi. Everything was working great until a recent DRM 11.x upgrade where all the resolutions settings that were previously working went out of wack, that is high screen resolution, no scaling, tiny text etc. I can't recall which 11.x upgrade caused the issues but it was one of the last couple of ones prior to the 12.x upgrade.
I was hoping the DRM 12.x upgrade would fix the issues with the resolution settings but unfortunately this wasn't the case and now the issue is starting to have an impact on productivity. You mentioned previously that the issue was with Microsoft however, I don't recall any Microsoft updates at the time. Are you able to provide any further insight into exactly what Microsoft had changed recently that was now affecting the ability to properly manage the screen resolution settings? Is the issue at the client end or the server end? I only connect to W7 and W2008R2 end points so I don't have any feedback to report on anything else.
What should the Remote Desktop Size and Screen Size Mode be set to? I was after a remote desktop that would scale as well as resize depending on the workspace area. I can't recall now what combination worked in the past but nothing I try now seems to work anymore. I've tried to uncheck the UI option Disable display scaling on high DPI settings as well but it didn't result in the outcome I was looking for.
There was a link provided earlier in the post to a Microsoft KB which had a fix for W7 and W28R which I haven't tried as I wasn't sure exactly what was the issue and why is why now happening. I'm reluctant to simply apply updates to production systems without first understanding more what the root cause of the issue is.
Regards
Dave
