Desktop app appears too small on high-DPI displays on Windows/Linux #861
Description

A small thing i have to say, can someone add a button to manually change the scaling? i have issues with my eyes and i can't see anything without 200% zoom..

I am on Windows 11 with a 5120x1440 ultrawide. That is roughly 109 PPI, so display-based auto-detection would classify it as a normal-density monitor and leave it alone, but the UI is still too small for me to read at the default. At that width the app spreads across a lot of physical space while the type stays at its base size, so the practical outcome is the same as the high-DPI case described here. I would want somewhere around 35 to 50 percent larger.
The existing zoom does not get me there. Ctrl and
=does nothing for me in the desktop app, which looks like the same failure as #4627, and there is no menu bar visible on Windows to reach View and Zoom In another way. There is also nothing in Settings that mentions text or UI size, so there is no discoverable path to a larger UI at all. The only remaining option I could find is the--force-device-scale-factorlaunch flag mentioned above, which means editing a shortcut target.That makes the "preserve manual user zoom adjustments" bullet in the original post worth widening slightly: expose the scale as a plain persisted value in Settings, alongside the auto-detected baseline. A number in Settings survives restarts, is discoverable without knowing a shortcut exists, and sidesteps the keybinding problems in #4627 and #2706 entirely rather than depending on a working accelerator.
Summary
On Windows and Linux, the desktop app does not automatically scale its UI on high-DPI displays the way macOS does. On 1440p and especially 4K monitors, the app can appear extremely small and difficult to use.
Problem
Electron does not automatically handle high-DPI scaling for this app on Windows in the same way macOS handles Retina displays. As a result:
This is especially noticeable when moving the app between monitors with different DPI / scaling characteristics.
Expected behavior
The desktop app should automatically scale its UI based on the current display so that it remains comfortably usable on high-DPI monitors.
