Yes, it's common for Windows to boot more quickly at times.

The master is decided by the initial display that connects, and avoid leaving the PC running.
but if the master decides that way, then when windows control activates it must switch the master to center display or the user's chosen primary display. some settings become fixed after post-testing. this requirement to change the primary will influence boot times on a consistent but slightly changing duration. additionally, three monitors at 240hz each result in a total refresh rate of 720hz. if you aim for roughly 80hz, the GPU can handle it, but the displays must adjust to reach their 240hz target.
I'm not sure about your issue, but my PALIT GTX 980 works fine after multiple tests. When using only one monitor and switching between PC power states, connecting to the far right port always displays the main POST screen. Plugging in a monitor through DVI makes it the main display as well.
Uncertain about the 240hz setting, as all my displays are currently configured at 60.
I'll share a video showing the differences between the two boots once I'm back.
Consider how Windows temporarily pauses itself during shutdown to speed up startup the next time. A restart or pending updates may interrupt this pause, extending boot duration. This ensures updates and drivers complete their setup properly, as part of the hibernation process. UEFI/BIOS significantly influences loading speed. BIOS actions (though not always precise) during startup—like CPU setup, graphics initialization, RAM recognition, and device scanning—shape how quickly everything comes together. It searches for the CPU, checks the GPU, identifies RAM, and verifies storage devices. Once it finds the main drive or SSD, it looks up the boot menu to launch the operating system. This sequence is managed by BIOS, which eventually hands over control to the CPU and starts the full boot. If hardware isn’t fully UEFI ready, a compatibility feature steps in to mimic BIOS behavior. In some cases, especially with older systems or limited components, the process can feel sluggish. However, with modern setups—especially those using Intel integrated graphics and solid storage—boot times can be remarkably fast, often under 7 seconds after pressing power. Brands like ASUS have demonstrated this in videos from earlier Windows versions, highlighting fully UEFI-supported systems.
