I understand the setup you're describing. You're using three monitors—two at 1440p and one at 5120x1440—connected to your GPU. To work around bandwidth limits on the 4090, you run two monitors at high refresh rates while the third uses the motherboard's HDMI. Recently, you updated drivers and performed clean installs, but bandwidth problems persist. I've tested HDMI, DP, various cables, and even different monitors. Connecting the same monitor to the GPU works, but bandwidth issues remain. Anyone have tips on troubleshooting graphics with the onboard card? Just for fun, I also updated all my 4090 drivers.
