I see, is there a clean way to uninstall 440 and install 450?
I don’t know how to do it in the terminal way,but in the gui you just right click the 440 driver and select remove,then right click on the 450 and select install,then you should reboot.
@XRaTiX That did the trick, I’ve upgraded to 450xx and I’m able to connect to my TV now, and xrandr -q outputs this:
>>> xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
...
HDMI-1 disconnected (normal left inverted right x axis y axis)
HDMI-1-2 connected (normal left inverted right x axis y axis)
...
However I still can’t switch to nvidia using optimus-manager, it still blacks out.
>>> inxi -G

Please help!
Intel is barely keeping up with the display, I see a lot of breaks in the display when I scroll.
You don’t need to switch to nvidia anymore to use the HDMI port,in the 450 driver you can now use hybrid mode the HDMI port,try using that one.
One note,i don’t know why still mark that you are using nouveau,thats weird.
Just tried hybrid mode and that blacks out as well. I’m using Nouveau in the swtiching method.
Yeah me too, anyways @XRaTiX thanks man I’m atleast happy that the HDMI works, have been at the HDMI thingy for a week now. But I’d really like to use the 4GB Nvidia card, somebody help!
Also, I’mn not able to open nvidia-settings which gives me even more reason to believe that something isn’t right with my drivers, should I start a new thread perhaps?
>>> nvidia-settings
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
Maybe thats why? you don’t have nouveau drivers so you should not use nouveau method,try using bbswitch method.
EDIT: Correction,you have nouveau drivers,but you are not using the nvidia propietary drivers.
There is a explanation in the optimus-manager wiki of what does each option,normally bbswitch works for most laptops,but try with bbswitch.
I just tried using bbswitch and rebooting caused my HDMI to stop working again 
I’ve installed bbswitch, but there is still a warning that pops up when I try to switch “The bbswitch module does not seem to be available for the current kernel”, and it logs back with the intel card.
Did you install the linux58-bbswitch?,that the one you should use because you have kernel 5.8
I think I broke my DM, I uninstalled linux414-bbswitch and installed linux58-bbswitch now I’m not able to boot into a DM…
Unable to open a tty either, tried at keys Ctrl + Alt + F1 to F12 …
Okay, I somehow managed to open a tty session by appending a 3 after quiet in the GRUB_LINUX line. I reinstalled linux414-bbswitch and I’m able to boot into a DM now…
Phew.
I tried installing linux58-bbswitch again, this time I kept linux414, but it still boots into the company logo 
what do I do?
I don’t use GNOME,but according to the guide you posted
install gdm-prime from AUR
On Manjaro Gnome you may have manjaro-gdm-tweak installed which requires gdm, so when you install gdm-prime, you get error because of the dependency with gdm.
You need gdm-prime from the aur,maybe you don’t have it installed?
I don’t know what is the cause of this 
I did install gdm-prime, I think the problem is occuring because I installed the wrong bbswitch package. I installed linux414 bbswitch.
I just tried to uninstall it from the pacam gui, and it warns me saying that
Warning: optimus-manager optionally requires bbswitch: alternative power switching meth
But when I removed it either way and installed linux58, it just boots into the company logo when I reboot.
I should probably start another thread explaining all the stuff again, especially about installing linux414-bbswitch, and linux58-bbswitch.
Sigh
Thanks @XRaTiX and @bogdancovaciu for your valuable input. Love the fact that there’s someone willing to help a random stranger.
P.S: Fortunately I’m still able to use the HDMI again, but with intel only.
Yeah there is something weird abut that linux414,the only thing i know is that linux414-bbswitch is for the kernel 4.14,but you are using the kernel 5.8,it should’t prevent the boot up,maybe you can uninstall that kernel if you don’t use it but i don’t know what would happen,either a black screen again or what…
I only have the kernel 5.8 and 5.4,I use the kernel 5.8 and have 5.4 as a safe backup kernel in case 5.8 starts to fail somehow.
When you resolve the issue with the bbswitch,you should be able to use the nvidia card
Also,make a backup with timeshift and have a usb with manjaro on it, just to prevent disasters later you can always restore the backup

I did make a timeshift backup, although it’s in the / partition itself, and I do have a bootable USB stick, so I’m prepared for the worst. It just beats me that I can’t use my dedicated graphics(that I spent extra money for), because I’m planning to shift to Manjaro entirely as a daily driver.
Do you think it’ll be a good idea to start a new thread asking why inxi -G, shows that my driver is
Device-2: NVIDIA GP107M [GeForce GTX 1050 Mobile] driver: nouveau
v: kernel
instead of hybrid-450xx? Maybe there’s a problem with my driver itself…
I don’t know about that,don’t hurt a try i guess but now that you mention it…you install the video-hybrid-intel-nvidia-450xx-prime,how is your mhwd -li?
I have this
mhwd -li

Do you have video-linux still installed? I think thats the nouveau driver and its preventing the nvidia driver to load properly? video-modesetting is the driver for intel so it should be there normal,try uninstalling the video-linux if you still have it.
Yes, this is mine:
