Hi,

I'm hoping this mailing list is active.... been through all the issues
logged at https://github.com/FreeRDP/FreeRDP and can't find an answer.

I remotely connect to multiple machines, recently I got a new 4K monitor
and am using that with a FHD monitor.

If I connect to a Windows Server 2012 the /multimon works perfectly well.

If I connect to a Windows 7 Pro, I am having problems with screen
resolution and allocation.


The following results in getting a screen resolution of 3840x2048
instead of the full 3840x2160

  xfreerdp /network:modem /drive:aaa,/mnt/tmpx \
     +clipboard +compression -wallpaper -themes /f \
     /v:win7.example.com:3390 /u:username

If I use /multimon instead of /f expecting to use both monitors as two
separate displays for the RDP session, I get a total screen resolution
of 4096x2048 and Windows 7 shows only 1 screen in display settings.

  xfreerdp /network:modem /drive:aaa,/mnt/tmpx \
    +clipboard +compression -wallpaper -themes /multimon \
    /v:win7.example.com:3390 /u:username

I am getting the actual screen resolution figures from Windows itself.
  (Control Panel\All Control Panel Items\Display\Screen Resolution).


This is my current setup:

$ xfreerdp /monitor-list
      * [0] 3840x2160    +0+0
        [1] 1920x1080    +3840+0

In the past the Macbook Pro with a 2880x1800 screen was connecting to an
actual Windows Server 2012 at the site that now only has Windows 7
machines available, but the Macbook Pro was seeing both screens and
using them properly just before a change to my client end setup.

I am using the exact same command line on the new setup as I was with
the Macbook Pro.  NB: Whilst the Macbook Pro has MacOs, I always use Linux.

$ xfreerdp --version
This is FreeRDP version 1.1.0-beta1 (git n/a)


The Macbook Pro was running Devuan (Live USB) Ascii version and the new
setup is using MX Linux, but I'm pretty sure that MX Linux worked
properly until the first time that I adjusted the display alignment,
then the problems arose and I can no longer get proper dual screen
working for the Windows 7 connection; it still works perfectly well with
the Windows 2012 at the different site.


I can't see anything at the client end to clear to "start again" and
don't know which registry or other settings at the remote end might help
to be cleared so as to reset everything.

Some details from "inxi -F"

I just reconnected the Macbook Pro and it still works perfectly, showing
dual monitors on the Windows 7 Pro machine.  Back on the new setup and
it still doesn't work; perhaps there is something I can reset or do to
fix it?

How can I get proper dual screen support to work again for connections
to the Windows 7 Pro box?


Thanks and Kind Regards
