Hi,
Hoping someone here can help me with this problem. I got the 4090, previously having the 6800XT, on boot, my monitor has no signal. However I can hear windows boot up, and pretty sure I can log in too.

Here's what I've done
  1. Downloaded the latest nvidia drivers (not installed)
  2. I used DDU to remove the AMD Drivers, selecting the option for a new GPU install, so it turned off my pc afterwards
  3. Connected the 12VHPWR PSU Cable to my PSU (Corsair HX1000)
  4. Plugged in the 4090 and then plugged the other end of the PSU cable into it
  5. Connect display port cable from my monitor to the 4090
  6. Turned on my pc
    1. The 4090 lights up and fans spin
  7. Monitor stays blank while I hear the Windows boot sound
    1. I can boot into BIOS (when using HDMI but still not seeing anyhting outside of bios)
Here's a few things I've tried
  1. Just left the pc on for at least 10minutes
    1. Read on Reddit, user just left it on for 4 minutes and they suddently had image, something about drivers automatically install in the background)
  2. Removed the 4090 and put my 6800XT back in
    1. worked with no problems apart from the weird resolution due to removing the AMD drivers
  3. Used the 12VHPWR cable that came with the card
  4. Plugging the 12VHPWR PCIE end into a different slot on the PSU
  5. Used HDMI cable
  6. Updating to the latest mobo bios
  7. Repeated the above install steps but from safe mode (and selecte the option to prevent windows from auto downloading updates)
Any suggestions?

Update
Issue resolved
  1. Swapped DP cable to HDMI, I noticed I could only get into BIOS with HDMI cable
  2. Disabled CSM
    1. If you have an integrated gpu or secondary gpu available, you can use Nvidia GPU UEFI Firmware Update Tool which seems to address blank screens for the 40 series. I had to pick one of the workarounds
      • "Change boot mode from UEFI to Legacy/CSM"
        • On my mobo CSM was already enabled, so I tried disabling it and this worked.
The above steps allowed me to get into windows where I then
  1. Used the firmware update tool on the 4090 and installed nvidia drivers
  2. Swapped out my cable for Display Port
  3. Re-enabled CSM in BIOS

Couldn't get a display signal on my 4090 either.
Pulled the HDMI cable from the TV and connected it to the PC.
Two PCs connected by HDMI, neither connected to a display...
