Solved Themes for different resolutions.

[longpanda]

There is no method to auto select theme according to the current resolution.

You can set more that one themes in ventoy.json as follows:

Code:

"theme": {
    "file": [
        "/ventoy/theme/theme_800x600.txt",
        "/ventoy/theme/theme_1024x768.txt",
        "/ventoy/theme/theme_1600x900.txt"
    ]
}

Then you can select theme by F5 Tools ----> Theme Select  as in the attachment.

But this need user to manually select the appropriate theme.
