### Godot version

v4.0.beta12.mono.official [3c9bf4bc2]

### System information

Windows 10, Forward+ (Vulkan), NVIDIA GeForce RTX 3070 (526.98)

### Issue description

The `Initial Screen` select dropdown provides 64 options for monitors when it should only provide options for what is available.  In my case, I'm only using two monitors so there should only be two monitors to choose from (excluding the Primary Monitor option of course).  Screenshot below.

### Steps to reproduce

The issue appears to occur whether I'm using two monitors or one monitor.

---
1. Open `Project Settings`
2. Go to `Display` > `Window` > `Size`
3. Select the `Initial Screen` dropdown.
4. You will see the `Primary Monitor` option and 64 other monitor options as seen in the screenshot.
