Grainy Image on New PC

[TheModelBoatGuy]

I have just upgraded to a new PC specially for use with Fusion 360. The new machine's default display resolution is 3140 x 2160. My designs on this new PC look grainy as if displayed at very low resolution. See attached screen captures from both old and new machine.

As a test, I tried lowering the display resolution on the new machine to 1920 x 1200 to match the old machine, but it makes no difference.

Can anyone please advise what settings I need to change?

Thanks

Forget this post, I solved my own problem. I just needed to switch on the option "Use high resolution graphics" in Preferences/Graphics/Display.
