Screen resolution on with 4k laptop and second full Hd screen problem

Hi All, I am new to CAD, before I can get into it I need to sort a resolution problem. I have a Dell laptop with a 4k screen and I often plug in an extended full HD screen with an HDMI cable. The problem is that LibreCAD the menus and icons etc are very small on 4k and nursery book style (v large) on the HD screen. Is there some setting I can adjust to fix this? Please remember I am a beginner and unfamiliar to LibraCAD, but I would be very grateful for any help you can offer me.

Faced with the same problem (menu fonts too small), the only solution I found, under Linux, is to launch it from a console with

        /usr/bin/xrandr --dpi 96 && librecad

If you get/find a better solution, I would be interested  ;-3à
 
Cheers,

Another solution is documented in a support request ('Issues'): https://github.com/LibreCAD/LibreCAD/issues/1054  On a Linux command line, type:

     QT_AUTO_SCREEN_SCALE_FACTOR=1 librecad &

See issue 1054 for more details.

None of the two works, alas...

ron@localhost:~ $ RS_DEBUG::setLevel(3)
RS_DEBUG: Critical
RS_DEBUG: Errors
RS_DEBUG: Warnings

ron@localhost:~ $ xrandr --scale 0.5x0.5  && librecad
xrandr: --scale must be used after --output
Try 'xrandr --help' for more information.

Also try at the command prompt:
    QT_SCALE_FACTOR=1.5 ./librecad &

The value can be adjusted as required.  0.5 was way too small.  1.0 was the normal scale, 2.0 was too big (icons).   1.5 was just right on a 4k monitor.  Just to be clear - that is the only command that needs to be used.

QT_AUTO_SCREEN_SCALE_FACTOR=  only accepts a value of is 0 or 1 (boolean).  For me, it resulted in something similar to QT_SCALE_FACTOR=2, which resulted in icons that were too large.

Hi Folks, thanks for the replies, but I am sorry, I did not gain a good sense of understanding. I tried the (dangerous) command prompt option but it did not work. However, I am using the win 10 OS and I don't think the mentioned advice was aimed at that OS. Please advice me with any thoughts, I would be very interested as I still have the problem.

In Options - Widget Options you can set icon size for the toolbar and text size for the status bar. Not a solution for all elements, but at least a partial improvement possible.
