At the beginning I installed all the graphics drivers found by Manjaro Hardware Detection (video Linux → was already installed, video mode setting and video vesa). However, when I rebooted I no longer had access to the log-in screen, so I had to set up my entire system again (the previous one was also brand new and almost empty, so not that bad).
Since then, I've left it with Video Linux and haven't installed the other two.
However, I'm a little dissatisfied with the resolution of videos when I play them.
Sometimes they seem a bit pixelated despite the supposedly high resolution (also on Netflix) and sometimes a kind of line appears in the middle of the screen, which is a little annoying. But I believe that the playback can't be that bad if it was of better quality even on my laptop (Windows) and I'm currently using a higher quality graphics card.
Then what could one attribute this poor quality to? Is it the driver's fault, could it be the monitor? The official drivers are only offered for Ubuntu, but I use Manjaro and I don't think I can use them.
I can't tell you why the drivers don't work properly (I hate vesa anyway, it never works), but why did you reinstall? You just had to go to another tty and uninstall the driver via MHWD or change it? You can also install the nvidia package if you have an Nvidia graphics card. I have little idea about other graphics cards. I'm currently using the mesa driver as an Intel graphics driver. You should also ask in the manjaro forums, they probably know more there.
I'm a new Linux user and still have too little idea
what should be a tty
A tty is a second session that runs without a graphical user interface. To put it simply, it's a terminal without a GUI. There are 6 of them in total. You can enter a tty with CTRL + ALT + the desired tty (i.e. One of the function keys 1-6). I'm not sure, but I think the GUI runs in tty1 or 6. In a tty you can do everything that you can do with a terminal emulator. In a tty you can repair your system, so in your case you can install a different driver with MHWD.
For example, if X11 does not start, your operating system is not lost. You can then go to a tty, look up X's logs, fix the error in the tty and start X.
