I’ve recently gotten a new computer and installed unity onto it, it has a decently good GPU (Nvidia 1650 Super) but despite that I am getting extremely low graphical quality in the editor.
Below I have attached 2 images, one showing what my editor graphical quality looks like, and the second showing that I have all of my settings on Ultra
This might be because of being on a device with more than 1 GPU.
For example - you have a laptop with a built in Intel GPU (very low performance) and a dedicated GPU (Nvidia/AMD) and it is defaulting the Unity editor to use the low performance GPU.
i have already changed it to the dedicated graphic card that is nvidia rtx 2050
but still it is the same …
I’m honestly not sure how that default cube could ever look so lo-fi. 
No, absolutely honestly, I don’t quite see what you’re getting at. This is an empty scene with just a cube in it and the default sky background. This always looks that low quality unless you put content in, add lighting, and postprocessing, and then enter playmode because the editor scene view doesn’t render all of the glorious details.
MSAA needs to be enabled on the camera too if I recall correctly, but I can’t say whether this will affect the editor camera.
The Quality Settings only shows you what the maximum settings can be. But you need to actively enable those in the scene, on the camera and/or a volume, in order to add postprocessing effects.
