A Way To Resize JMP window in exact pixel

[ChowDPa02k]

For most modern video players (PotPlayer, VLC, etc.), they usually support automatic resizing of the window to match the video's dimensions.

This function is important for high-resolution screens, such as playing 1080p content on 2K/4K monitors.

Otherwise, the video playback will suffer from upscaling algorithms, making the picture blurred.

Unfortunately, JMP hasn't implemented this feature so far. It's quite cumbersome to drag a window with pixel-level accuracy. I've tried this before, and even with a 3x magnifier, I couldn't do it well.

Windows

On Windows, there is no native way to resize a window to precise dimensions. However, there's a tool for us: Sizer, which can handle this task well.

Sizer will hook the right-click action on the edge of a window (when your cursor turns into a resize icon). Just configure it for a 1080p windowed mode...

Note: Sizer calculates the entire window size, including borders and the title bar, so the default 1080p gives a content area that is actually smaller than 1920x1080.

Depending on the system's display scaling settings, the height of the title bar may vary.

So how do we ensure we get a perfect 1080p size? Just check the log:

%localappdata%\JellyfinMediaPlayer\logs\JellyfinMediaPlayer.log

And search for resize event: QSize, you can find the actual size of the content area.

Example

For a 2K monitor with 100% scaling, you should configure it to 1922x1112 (1920+2, 1080+32).

For other scaling factors, start with (+2, +32) until the log finally shows the actual QSize(1920, 1080).

Ubuntu

wmctrl -r "$(wmctrl -l | grep 'Jellyfin Media Player' | awk '{print $1}')" -e 0,0,0,1920,1080
