FRLogger and display resolution

Hi all,

First, thank you for trying and for some of you using FRLogger.

I've had a number of people send in problem reports with respect to 4K monitors and increased scaling percents.  Here is some clarification on the issue:

FRLogger is a WinForms app currently.  WinForms is Microsoft's older display technology.  I selected it over newer modes like WPF or UWP because of ease of development.  I work in UWP and WPF every day and the time it takes to do certain things you can do in a single line of code in a WinForms app at times can be 2x-4x longer.

WinForms does not handle high DPI monitors very well.  Microsoft as made some patches but it is still not perfect.  WPF/UWP apps do a far better job.  Part of this is simply because high DPI monitors are relatively new, newer than the WinForms technology.

The other problem creator is the scaling.   In Windows 10, when setting your display resolution you see a dialog like below:

The scaling value is set in the "Scale and layout" field.   

As monitors have increased in resolution, people, (and Microsoft), have started to use and suggest setting the scaling to something like 150%.  This unfortunately is the worst case example for FRLogger.

This will cause fields to overlap, things not to line up, etc.

At this point in time I do not have a fix for you that will allow you to use your high DPI monitor at scale percentages like 150% and 200% without having some issues in FRLogger with how things display and align.

I will continue to work on the issue and see what resolutions I can find and present but for now if you want to use FRLogger on a high resolution display it would be best to keep the scaling at or close to 100%.

Also, when testing different screen resolutions and scaling to see what will work you cannot just change the scaling and check out a current running instance of FRLogger.  FRLogger really has no clue the scaling has changed.

So the right way to test different resolutions and scaling are as follows:
  1. Shutdown FRLogger
  2. Change the resolution or scaling in Windows as desired and accept the changes
  3. Restart FRLogger and examine the panels
If things look ok to you then you should be good to go.  If things are not lining up well I suggest:
  1. Shutdown FRLogger
  2. Log out of windows.  
  3. Log back into windows
  4. Run FRLogger and check out the panels.
Windows even notifies you that at times you need to log out and log back in for apps to receive notifications of the changes.

If you have a particular resolution you want to run and things are not aligning well please send me a screen shot of your monitor settings (above) and a screen shot of FRLogger and the panel that is not working well.

I am more than willing to try and make some adjustments.  Just understand I cannot handle every possible resolution.
