A while ago, I’ve installed EndeavourOS on my new Zephyrus G15 laptop and until today, only used it with one external ultrawide monitor. Today, just to test, I’ve hooked up a second external monitor and with just some minor display settings adjustments, all three screens function as expected.
It’s mind-blowing how far Linux has come!
For now, I am dual-booting with W10 Pro but based on my first week of running EndeavourOS on this laptop, I most likely will nuke W10 soon.
i use external too. sometime extended, sometime miroring, and sometime just …external. , dual boot with win 11 Pro 
Can you update all the firmware/bios from Linux. Im running Dell and can upgrade bios but if I for example wish to update the thunderbolt firmware I need windows, so I always keep a small windows installation for that reason.
I know that Ubuntu/Pop OS does it via the software center/app then reboots and can do firmware, fedora too. Not sure how to do it in arch.
Have a look at:

Check if your machine is supported. If it is you might be able to update some device’s firmware as well.
Yea I know but as I said the thunderbolt firmare comes as an installible exe file from dell that require windows witch makes it kinda hard. Bios work.
I see. I missed that from your previous post 
In that case something like:

might work.
I use it to update the UEFI firmware which comes as a .exe file on a Lenovo laptop. It’s been working well for that purpose. May be worth to investigate it for your purpose.
Yea, looks promising for shure gonna check out. Thanks.
Hi grymphen,
my laptop is too new as I just got it a few weeks ago. On my dell machines (all running EOS only), I just download the critical updates and update via BIOS.
ASUS, as I understand, isn’t as Linux-friendly as DELL but I will soon enough check this out and update.
