I recently set up a dual boot on my older HP Envy i7 running Windows 10, and everything worked perfectly with the external display. Feeling inspired, I decided to do the same on my Lenovo Legion i9 at 3am. That install went well too, but after all the updates and fiddling with driver settings, it won't detect my two external displays—one connected directly to the GPU and the other through a USB-C dongle. I'm wondering, could switching from dynamic to discrete settings help? But I'm worried it might impact my Windows 11 setup, which I'd like to avoid. If I do decide to remove the Linux partition, is it as simple as deleting the partitions and then removing the boot option through the command prompt? By the way, my GPU is an Nvidia GeForce RTX 4070 with 8GB. Thanks for your help!

First off, double-check if you have the Nvidia driver installed and loaded. You can do that by running `nvidia-smi`. If that looks good, it might just be a limitation with X11's handling of displays. Wayland generally offers better support for multi-monitor setups, but Mint currently doesn't have desktop environments with solid Wayland support. KDE and Gnome are your best bets for that—consider trying a distro that features one of those. Before you jump into a new distro, maybe test out multi-monitor setup first to see if your drivers support it!
Oh, I see! I think external displays worked when I first booted, but they stopped after I updated to the so-called 'recommended' Nvidia driver. I might have been a bit tipsy when I did it! I'll try out the alternative driver versions to see if they help.
