Precision 7540 with WD19DC and RTX3000
Running just what it says in the subject, needing to run dual 4K monitors. According to the bandwidth/resolution charts, I should be able to do this. But no matter what I do, the second monitor will not allow me to go above 2048x1280. Even if I downgrade one of the monitors to 1080, the second will NEVER allow me a higher resolution. I'm running both on DP ports. I've upgraded all my drivers.
In case it's a symptom of my docking station being messed up... just thought I'd throw out there that the power light on my docking station doesn't work, and often one of the lights on the USB-C cables won't light up.

UPDATE: At one point I had this set up working just fine... and I forgot that in order to do that, I'd had to manually update my BIOS and reset some settings in there. I'd reformatted a few months ago, which obviously undid all that. So if you have a setup like mine, and are having issues... check the BIOS version and its settings. There are a LOT of good step by steps in this forum about that very topic.
Leaving this up in case it helps anyone.
