Default Resolution settings

I am connecting Dell laptop Inspiron 13 5379 Windows 10, USB output to TV VGA input, using a Coredy MDA1920, which uses the DisplayLink DL-165 chipset and software. My Dell prefers to runs at 1920x1080. My TV appears to run at 1280x1024.
Trying these default settings using Win+P key combination: Display only on laptop works, Display only on TV only works, Extend over both laptop and TV works. However Duplicate/Mirror mode seems not to work. If I reduce the Dell resolution to 1366x768 (or less) the duplicate/mirror mode works.
Is this a resolution conflict issue? Is this behaviour expected, or is this a setting I need to adjust?
Advice and help please.

Hello Peter,

Clone mode must use a resolution supported by both displays. Windows doesn't allow scaling to match keeping the aspect ratio.
The system will default to the highest resolution supported by both, comparing the supported mode list.

From your description I am unable to understand what resolution you want on both.
If you tell me which one it is, and you have the .edid file saved in the DisplayLink folder (C:\ProgramData\DisplayLink\Debug), I can see if the external display advertises supporting it.

Kind regards,
Alban

Thanks. I didn't realise that Windows needed matched resolutions for clone/duplicate/mirror to work. Of course that is quite understandable. I wanted to know how this worked, as I may need to plug my high resolution laptop into lower resolution projectors when in meetings (which is why I was experimenting with my TV). Query resolved, thank you.

You're welcome Peter,
For presentation, extended desktop might be preferable.
For instance, PowerPoint will show you your current slides with speaker notes and an overview of the following slide on your local display with a timer whilst only showing the current slide full screen on the second display. It reminds you of what is coming next.
Kind regards,
Alban
