Graphic driver display issues - hybrid intel and Nvidia - external monitor

Hey all

I’m a complete newbie to Linux. In beginning stages of understanding all the terminology, commands etc ... I’m not techie.
I have a Dell XPS 502 with intergrated intel and Nvidia GF 540m card.
After a disappointing start with POP OS, I decided to try Manjaro KDE and seemed very impressive. BOTH monitors appeared to work at first. But then I noticed some “lag” wave effects when scrolling fast. I’m not exactly a gamer but want to do graphics work, I’m illustrator.
So after getting somewhat familiar I tried switching to Bumblebee hybrid drivers hoping for better performance.
But then external monitor stop working, pc no longer projected to external. So I tried the main Nvidia only drivers and no change. Then I tried going back to “video Linux” drivers again, but still no external monitor working.
I read about Optimus, installed and ran that, but again after installing hybrid and standalone Nvidia drivers, it told me it can’t find any optimus drivers.

Again I’m very new, baby steps ... any help would be appreciated, but my knowledge in terminal commands limited. From a previous post I got these commands & info that said would be requested.

I’m very confused by that ... bit overwhelming to be honest, will try wrap my head around it.
How do I know if my card supports 440 or not? And how do I know if my card is optimus enabled?
I checked, no way to switch off iGPU in bios.

Heck isn’t there an easier way to get Nvidia intel dual screen working? That info is crazy for someone new to Linux ... my brain just sizzled. I need some more direction on what to do, what line to run to activate this and maybe some short child like (for me) instructions on how to implement this.
Possible or do I need to first need to learn Linux before being able to set up graphics on external monitor?

Ps ... originally Manjaro at least detected my external monitor, but now it’s not even detected under settings/display, only shows laptop display, no external hdmi display ... even although I tried all the available drivers again (except vesa)

Newbie here jumping in... having exact same issue. I connected my laptop to a second monitor. Synced up very easily.. and then I updated the graphics driver which is now the 440xx prime, and it's not even trying to find my monitor now. Can't find much info so far on how to get things to work properly.. hmm

Hi ... apparently (and I might be wrong) ... so far Only the Linux-video drivers support external monitors. Apparently the Bumblebee and Nvidia drive does not , for now
