I'm having a challenge with a 4 monitor set up with the KINGPIN 3090.  I recently upgraded my main monitor to a 4k 240hz Oled panel from ASUS (love it), but now I can only connect 3 total monitors.  Prior to that I could connect 4 2k monitors.   I've tried switching from a Display Port cable to an HDMI 2.1 cable that came with the monitor, but still no luck.  I was asking ChatGPT for help and it looks like I might be using the maximum bandwidth available for the card but wanted to check with the community to see if there another configuration that I could get to work without having to add a second GPU.
 
GPU - KINGPIN 3090 Hydro Copper
Monitors:
1. Main: 32" 4k 240hz ASUS ROG PG32UCDM
2. Samsung 32" 2k 165hz G51C (Landscape)
3. Samsung 32" 2k 165hz G51C (Portrait)
4. Samsung 32" 2k 165hz G51C (Portrait flipped)

Make sure all your dp cables are vesa certified. The 3090 can push up to 33,177,600 pixels. A setup of one 4k monitor and three 2k monitors would be 19,353,600 pixels which is way under the limit.

No problem. Did that solve your issue?

Firmware up to date?  There was an issue with DP if I recall correctly.
