I absolutely love my Spectrum monitors! One thing i am a little flummoxed by is my monitor not not coming on until Windows login screen, not allowing me to see the boot screen or bios. I have to unplug my Spectrum and plug in my old monitor to access the bios.
Any suggestions? Is there a setting where I can change this?
Edit: fixed! I needed to flash the bios on my gpu (1080ti) to support Display Port 1.4 natively
i had this issue before. i no longer have this issues ever since i upgraded my motherboard to a z390-a and gotten an i9-9900k cpu. i get asus bios to appear instantly right after i turn my pc and monitor on. my old z270-a i wasn’t getting a boot screen. maybe try another spare motherboard if you have one lying around?
I’ve got a i9-9900k in a Asus Maximus XI Extreme with latest bios. Unfortunately I don’t have a spare mobo to test with. But, if my previous monitor worked and showed boot screen, then surely it’s not the mobo?
I experiencethe same via DP, but not via HDMI. Until now, I thought this is due to that my motherboard (2011) has a non-UEFI BIOS that probably uses the classic 640x400@70Hz and/or 720x400@70Hz modes during boot, and Spectrum’s EDID lacks those modes.
But your CPU and motherboard are much more modern (2018), and BIOS is surely UEFI. So a regular video mode like 1024x768@60Hz is probably used during boot, so I’m now not sure what the issue reason is.
Also, Windows 7 shows flickering black screen with Eve Spectrum and cannot be used in my case.
I don’t have these issues with my Dell P2415Q 4K monitor I use via DP/MiniDP since 2015.
I have the same setup as you (ASUS x570-I / 5950x / ASUS TUF RTX3080ti / HDMI 2.1 cable)
I updated the latest firmware, Nvidia driver and an GPU bios update from ASUS in Aug, bought a premium HDMI cable, a lot of unplug/re-plug to different ports, then the issue was fixed. But I’m not sure which step exactly fixed the problem though.
Need to look into that, but I still believe it’s EVE related, since on dual setup my other screen does show BIOS until EVE gets on and login screen jumps to that. Also on single screen setup, the other screen does show bios, but EVE not.
BIOS updates are only for 30 series of nVidia GPUs. My GPU is GTX 650 Ti Boost (2013), so this is not an option. With the same GPU via the same DP using the same DP cable, another 4K monitor — Dell P2415Q — shows computer boot with no problem.
