Okay. If you can find the model number, that could help. Also, is the HDMI cable new? I know recently I’ve had a cable not detect a monitor correctly somehow and had to order a new one after returning it.

just found the model number:
C248W-1920RN-314
do you mean order a new HDMI or should it be Displayport?

There are a few similar models. If you have the one with Displayport (looks to be labeled purple in recent versions of the back of the C248W-1920RN monitor from 2018) try a Displayport cable. They are usually better to use and have a more secure connection.
Oh, and my recent experience with a faulty cable was a HDMI. I don’t know how or why, but a generic HDMI cable from Walmart ended up working better

Garuda (2.6.19-2):
System install date: 2023-11-14

Is partially upgraded: No
Relevant software: snapper NetworkManager dracut
Windows dual boot: Probably (Run as root to verify)
Failed units:
yep, I’ll restart
are there any monitors that are guaranteed to work with Garuda? should I only be concerned about getting a new HDMI Cable?
After looking into new BIOS versions, one mentioned fixing an error of blank displays on power up. I am not sure, but that could be a related problem to what your are facing and I would update to the lastest BIOS just to be sure.
Most monitors should have no problem with working with Garuda. Most do not need additional tinkering to work correctly. I know Spectre isn’t the most trusted brand, but you should be able to set supported resolutions using Garuda at the very least I would think. It wouldn’t hurt to upgrade your monitor however; That 4070 graphics card of yours using at least a 144hz monitor using displayport would be ideal. Don’t want that graphics card going to waste.

on it, will keep you in the loop with updates

Mhhh, a DP/HDMI cable are cheaper than a new monitor, isn’t it?

Also more easily returned 
Always best to troubleshoot the easier things first and work your way up I find

yep, very much so
on the virtual machine for example, I noticed you could change the resolution from the program and not internally on Garuda and that solved it quickly, it even recognized it as Virtual-1 in the specs, and because I also noticed that on most monitors you can change the resolution on them but not mine for some weird reason
and I got only HDMI and VGA, no displayport connection, bummer
Posted this on a different thread but I thought I would repeat this here for added visibility:
Searching more on the issue today, I came across this “Unknown” primary display (Gnome + Nvidia + Dual monitor) / Newbie Corner / Arch Linux Forums suggesting to enable DRM (Direct Rendering Manager) for Nvidia NVIDIA - ArchWiki

sorry for the long delay, I got swamped with work, right now since I don’t have a supported cpu, I have to Q-flash the BIOS to the motherboard, I’ll do that by Friday and keep you posted
I couldn’t update the BIOS, traditional updates kept failing with no error code returned, the Q-flash method didn’t work because it couldn’t verify the new update image. Waiting on the new HDMI cable, also a new monitor.
I was able to fix this by doing the following steps.
- Edit the GRUB configuration file:
sudo nano /etc/default/grub- Find the line with GRUB_CMDLINE_LINUX_DEFAULT
- Append the words inside the quotes with nvidia-drm.modeset=1
- Example: GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash nvidia-drm.modeset=1”
- Save the file with CTRL+O
-
Update the GRUB configuration:
sudo grub-mkconfig -o /boot/grub/grub.cfg -
Reboot

on it!
it is stuck on the AORUS logo, do I wait?
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash nvidia-drm.modeset=1”
are there spaces between quiet splash and splash nvidia?
it got me to boot failed to start remount root and kernel file system when I tried to load an earlier snapshot
Yes, delete the quiet.
For
you can use
sudo update-grub
too.
Also, micro for nano. 
Please, post log from
pacman -Qi nvidia-settings
