Auto-generated thumbnail size

[PsychicSmurf]

Describe the bug
Using a browser on a monitor with a different resolution to my "primary" monitor auto-generates thumbnails of an incorrect size which then do not display correctly.

Steps To Reproduce
Dual Monitor Setup: Primary = 2560x1440, Secondary = 1080x1920 (Portrait)
Browser in Secondary Monitor

Grid Layout - Fill Space (8 columns x 8 rows)

Create a Web Page Dial (https://calendar.google.com/calendar/u/0/r/agenda)

Configure Dial to 4 Columns 4 Rows (one quarter of screen)

No Crop / Scale enabled.

Auto-generated thumbnail size is: 676 x 279

This resolution would be correct for my primary monitor however it is completely wrong for my secondary. If I am generating a thumbnail I would expect it to use the resolution of the monitor that the browser is displayed on, or have a way to adjust the auto-calculatyed values.

Expected behavior
The thumbnail should allow for a custom size to be entered so that it can display correctly regardless of monitor.

Device info:
Windows 11
Firefox 130.0.1 (64-bit)
Speed Dial v26.0

Hello,
This should be configurable, although I'm not sure it will handle "portrait" dimensions, since there were some issues, I have a feeling it's restricted to "squared" thumbnails.
In any case, open Options page / Thumbnails / Auto-reload target screen resolution - switch it to Manual and then enter your monitor resolution.

Note that my addon will look for the "biggest" monitor, so that the thumbnails are always "sharp", but portrait mode is a special case...

And lastly, using different group layout may also help - right click group name / Edit group. Here choosing "dynamic" or "center/scroll" would fix the thumbnails since they use fixed size thumbnails.
