My initial setup involved thorough research and preparation, resulting in mostly successful operation. I managed to boot into BIOS, updated the drivers, and installed Windows 11. All video drivers were updated, devices verified, temperatures normal, and everything functioning properly.
Nevertheless, after shutting down the machine, I tried restarting via power button and then pressing F2 during startup. The display briefly appeared for a DP signal before everything reset. Once back in BIOS, the system booted normally and Windows loaded correctly. However, no screen was visible.
Interestingly, pressing F2 repeatedly during startup activated the display and allowed me to navigate the BIOS menu and boot into Windows successfully. I was able to restart without issues, but only after a complete shutdown.
I have performed a clean Windows installation three times (removing all other drives, now using a single NVMe SSD), yet the same problem persists—system boots into BIOS and Windows, but no display appears unless I enter BIOS first.
I also replaced the RAM, swapped the CMOS battery, and removed the old CMOS battery; all components appear intact. Based on this, the issue likely lies in the boot sequence or configuration rather than hardware faults.
EDIT: I have also experimented with different settings in BIOS and Windows Startup to see if adjustments resolve the problem.
Any suggestions or solutions would be appreciated.
Thanks!
It might help to monitor the GPU signal resolution. When switching between monitors, it takes around 20 seconds using a KVM to change from 1440 to 1080, even though the second monitor isn't its native setting. Could be a useful idea.
Also, try using an HDMI cable instead of a DP connection?
I’ve checked using HDMI as well, and the outcome remains the same. No video signal appears, not even after waiting a long time, unless I manually enter BIOS first. I’ll try another monitor or cable soon, but I suspect this isn’t the problem. (Note: My monitor is a 27” Samsung Odyssey G50A QHD, 1440p.)
